New Features for Supervisor Engine Software Release 4.4 New Features for Supervisor Engine Software Release 4.4 This section describes the new features available in software release4.4. Layer 3 fabric integration module (WS-X5305)—Seamlessly integrates the Catalyst 5500 switching backplane and the Catalyst 8510 campus switch router (CSR) backplane in a Catalyst 5500 chassis by providing an internal Fast EtherChannel trunk between the two switches. New Features for Supervisor Engine Software Release 4.
New Features for Supervisor Engine Software Release4.2 New Features for Supervisor Engine Software Release 4.2 This section describes the new features available in software release4.2. • Dynamic Trunking Protocol (DTP)—DTP supports negotiation of both Inter-Switch Link (ISL) and IEEE 802.1Q VLAN trunks. • Disable receive traffic on Switched Port Analyzer (SPAN) destination port—You can prevent normal receive traffic from entering a port configured as a SPAN destination.
New Features for Supervisor Engine Software Release4.1 • Switch TopN reports—Provides metrics for port utilization, broadcasts, multicasts, unicasts, and errors, sorted by TopN ports in the switch. • IP Traceroute Support—Provides support for the standard Internet Control Message Protocol (ICMP)-based IP traceroute facility from the system console. • Token Ring VLANs in RSM—Provides RSM support for Token Ring VLANs.
Open and Resolved Caveats in Software Release 4.5(13a) – Three-port Gigabit Ethernet Module—Provides three 1000BASE-SX Ethernet ports; supports ISL and 802.1Q trunking, broadcast suppression in hardware, 802.3x flow control, and is full duplex only. This module does not support Gigabit EtherChannel port aggregation. (WS-X5403) – NetFlow Feature Card (NFFC)—Enables new features for the Supervisor Engine III, including MLS, IGMP snooping, and Protocol Filtering.
Open and Resolved Caveats in Software Release 4.5(13) Workaround: Reenable protocol filtering, which will restore multicast traffic forwarding. If you do not want to reenable protocol filtering, you must reset the switch to resolve the condition. (CSCdu04672) • On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.
Open and Resolved Caveats in Software Release 4.5(13) Open Caveats in Software Release 4.5(13) Note For a description of caveats resolved in software release4.5(13), see the “Resolved Caveats in Software Release4.5(13)” section on page19. This section describes open caveats in software release4.5(13). • When operating at 10MB, a disabled port on a WS-X5224, WS-X5012, WS-X5012A, or WS-X5014 module will continue to transmit link pulses. This causes the link-partner port to stay up. There is no workaround.
Open and Resolved Caveats in Software Release 4.5(13) Resolved Caveats in Software Release4.5(13) Note For a description of caveats open in software release4.5(13), see the “Open Caveats in Software Release4.5(13)” section on page18. This section describes resolved caveats in software release4.5(13). • The Catalyst 5500 series switch might crash when you make Telnet connections between the switch and the RSM. Workaround: Reload the switch. This problem is resolved in software release 4.5(13).
Open and Resolved Caveats in Software Release 4.5(12) Open and Resolved Caveats in Software Release 4.5(12) This section describes open and resolved caveats in supervisor engine software release4.5(12): • Open Caveats in Software Release4.5(12), page20 • Resolved Caveats in Software Release4.5(12), page21 Open Caveats in Software Release 4.5(12) Note For a description of caveats resolved in software release4.5(12), see the “Resolved Caveats in Software Release4.5(12)” section on page21.
Open and Resolved Caveats in Software Release 4.5(12) Resolved Caveats in Software Release4.5(12) Note For a description of caveats open in software release4.5(12), see the “Open Caveats in Software Release4.5(12)” section on page20. This section describes resolved caveats in software release4.5(12). • Supervisor Engine III sends CGMP packets to routers with a source mac address of all zeros. This problem is resolved in software release 4.5(12).
Open and Resolved Caveats in Software Release 4.5(11) The reset is caused by a high number of MLS-enabled interfaces with HSRP and static MAC addresses configured. The fix allows MLS to be enabled on a large number of interfaces configured for MLS. This problem is resolved in software release 4.5(12). (CSCdp08252) Note that the RSM IOS software must be upgraded to 12.2(1) or later.
Open and Resolved Caveats in Software Release 4.5(11) • On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port. Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired).
Open and Resolved Caveats in Software Release 4.5(10) Open and Resolved Caveats in Software Release 4.5(10) This section describes open and resolved caveats in supervisor engine software release4.5(10): • Open Caveats in Software Release4.5(10), page24 • Resolved Caveats in Software Release4.5(10), page24 Open Caveats in Software Release 4.5(10) Note For a description of caveats resolved in software release4.5(10), see the “Resolved Caveats in Software Release4.5(10)” section on page24.
Open and Resolved Caveats in Software Release 4.5(9) • To avoid high CPU utilization from a show logging buffer command, do not display more than 20 messages when the screen length is set to 0 or greater than 24 with the set length command. This problem is resolved in software release 4.5(10).
Open and Resolved Caveats in Software Release 4.5(9) Open Caveats in Software Release 4.5(9) Note For a description of caveats resolved in software release4.5(9), see the “Resolved Caveats in Software Release4.5(9)” section on page26. This section describes open caveats in software release4.5(9).
Open and Resolved Caveats in Software Release 4.5(8) • When upgrading Supervisor Engine II from software release 3.2(5) directly to software release 4.5(7), the clock may report an earlier date and become stuck after the reset. Use the set time comm to recover the correct time and start the clock. This problem is resolved in software release 4.5(9). (CSCdr89912) • The switch might display “Out of memory” messages, which can cause VMPS to become inactive.
Open and Resolved Caveats in Software Release 4.5(7) Resolved Caveats in Software Release 4.5(8) Note For a description of open caveats in software release 4.5(8), see the “Open Caveats in Software Release4.5(8)” section on page27 . This section describes caveats resolved in software release 4.5(8): • When a port on a WS-X5012 or WS-X5012A module is disabled, the OutOctet counters might report an incorrect value if the value is larger than can be displayed with 32 bits.
Open and Resolved Caveats in Software Release 4.5(7) Open Caveats in Software Release 4.5(7) Note For a description of caveats resolved in software release4.5(7), see the “Resolved Caveats in Software Release4.5(7)” section on page29 . This section describes open caveats in software release4.
Open and Resolved Caveats in Software Release 4.5(7) • If you save a configuration file from a switch where Token Ring is not configured, and then apply the saved configuration file to that same switch, it is safe to ignore messages about TRBRF and TrCRF VLANs. These messages are caused by the default Token Ring VLAN configuration, which is always present regardless of the specific configuration of the switch. This problem is resolved in software release 4.5(7).
Open and Resolved Caveats in Software Release 4.5(6) Open and Resolved Caveats in Software Release 4.5(6) These sections describe open and resolved caveats in supervisor engine software release4.5(6): • Open Caveats in Software Release4.5(6), page31 • Resolved Caveats in Software Release4.5(6), page31 Open Caveats in Software Release 4.5(6) Note For a description of caveats resolved in software release4.5(6), see the “Resolved Caveats in Software Release4.5(6)” section on page31 .
Open and Resolved Caveats in Software Release 4.5(6) This section describes caveats resolved in software release 4.5(6): • If a large number of RMON history, alarm, and event entries are continuously deleted and added, the RMON alarmTimer experiences a memory allocation problem. This problem is resolved in software release 4.5(6). (CSCdp58575) • When a FDDI port is trunking, a fast link flap may cause the port to stop trunking. This problem is resolved in software release 4.5(6).
Open and Resolved Caveats in Software Release 4.5(5) • The switch might reset following a show configuration command if the login banner is set through SNMP and is longer than 200 characters without a return. This problem is resolved in software release 4.5(6). (CSCdp65405) • Permanent CAM entries created by MPOA are not removed when an ATM module is removed or reset. This problem is resolved in software release 4.5(6).
Open and Resolved Caveats in Software Release 4.5(5) Workaround : Configure standby use-bia on the router interfaces for the HSRP (standby uses the interfaces burned in address [bia]). (CSCdp51787) • If you save a configuration file from a switch where Token Ring is not configured, and then apply the saved configuration file to that same switch, it is safe to ignore messages about TRBRF and TrCRF VLANs.
Open and Resolved Caveats in Software Release 4.5(5) Resolved Caveats in Software Release4.5(5) Note For a description of open caveats in software release4.5(5), see the “Open Caveats in Software Release4.5(6)” section on page31. This section describes caveats resolved in software release 4.5(5): • If a switch is configured with the sc0 interface in a Token Ring VLAN, and there are parallel trunks to another switch, it is possible for the first switch to erroneously detect a duplicate IP address.
Open and Resolved Caveats in Software Release 4.5(4) • After a switchover, ports that are in a Port Security shutdown state on the 10/100 Mbps Fast Ethernet Switching Module (WS-X5224) do not recover their links to workstations connected to those ports. If the cables on the ports are disconnected, the link lights remain green and the link is not dropped, indicating that the ports are connected and spanning tree is in forwarding state. Resetting the module is the only means of recovering from this problem.
Open and Resolved Caveats in Software Release 4.5(4) Open Caveats in Software Release 4.5(4) Note For a description of caveats resolved in software release4.5(4), see the “Resolved Caveats in Software Release4.5(4)” section on page38 . This section describes open caveats in software release4.5(4).
Open and Resolved Caveats in Software Release 4.5(4) Resolved Caveats in Software Release 4.5(4) Note For a description of open caveats in software release4.5(4), see the “Open Caveats in Software Release4.5(4)” section on page37 . This section describes caveats resolved in software release 4.5(4): • Under certain conditions, the switch can access an out-of-range memory location, causing the switch to reset. This problem is fixed in software release 4.5(4).
Open and Resolved Caveats in Software Release 4.5(3) Open and Resolved Caveats in Software Release 4.5(3) These sections describe open and resolved caveats in supervisor engine software release4.5(3): • Open Caveats in Software Release4.5(3), page39 • Resolved Caveats in Software Release4.5(3), page40 Open Caveats in Software Release 4.5(3) Note For a description of caveats resolved in software release4.5(3), see the “Resolved Caveats in Software Release4.5(3)” section on page40 .
Open and Resolved Caveats in Software Release 4.5(3) Resolved Caveats in Software Release 4.5(3) Note For a description of open caveats in software release4.5(3), see the “Open Caveats in Software Release4.5(3)” section on page39 . This section describes caveats resolved in software release 4.5(3): • Autonegotiation between Sun 10/100 NICs and certain Catalyst5000 family modules (such as the WS-X5225R) might result in speed and/or duplex mismatches under certain conditions.
Open and Resolved Caveats in Software Release 4.5(2) • If you configure a port as an ISL trunk in on mode and the neighbor port is configured in off mode, the switch still forwards Token Ring ISL frames over the link. Workaround: Correct the misconfiguration by configuring the ports to compatible trunk modes (for example, both off, both on, one desirable and one auto, and so forth). This problem is fixed in software release4.5(3).
Open and Resolved Caveats in Software Release 4.5(2) Open Caveats in Software Release 4.5(2) Note For a description of caveats resolved in software release4.5(2), see the “Resolved Caveats in Software Release4.5(2)” section on page43. This section describes open caveats in software release4.5(2).
Open and Resolved Caveats in Software Release 4.5(2) Resolved Caveats in Software Release4.5(2) Note For a description of open caveats in software release4.5(2), see the “Open Caveats in Software Release4.5(2)” section on page42. This section describes caveats resolved in software release 4.5(2): • In some cases, multiple Catalyst5000 family switches connected through ISL trunk ports might all report that they are the designated root for the default TrBRF (VLAN 1005).
Open and Resolved Caveats in Software Release 4.5(2) • In a switch with one or more 24-port 10/100BASE-TX Fast Ethernet module (WS-X5225R) or the 12-port 100BASE-FX Ethernet (WS-X5201R) modules, the swBusSBDErrorDrop counter in the show counters output increments if the module detects invalid frames on the backplane. Such frames are discarded and have no effect on the normal operation of the switch. This counter has been renamed swBusSBDEvent in software release4.5(2).
Open and Resolved Caveats in Software Release 4.5(1) • If you configure the IP address of the in-band (sc0) interface with an address in subnet zero of a ClassB address and 24bits of subnet mask, IP traffic destined for other subnets in the same ClassB network are not forwarded to the default gateway. For example, if the sc0 IP address is 172.20.0.10/24, a ping to any other address in the 172.20 ClassB network (except for those in the 172.20.0 subnet) fails.
Open and Resolved Caveats in Software Release 4.5(1) • In some cases, when you connect a port on the 24-port 10/100BASE-TX Fast Ethernet module (WS-X5225R) to an end station, the port might loop data back to itself. If spanning tree is disabled on the port, this problem can negatively affect switch performance. If spanning tree is enabled, the port is automatically disabled.
Open and Resolved Caveats in Software Release 4.5(1) • On some switch ports, if you enable port security on the port before the port is in the spanning tree forwarding state, port security might shut the port down. This problem occurs only if BPDUs, broadcast packets, or other traffic is received on the port before the port enters the forwarding state.
Open and Resolved Caveats in Software Release 4.5(1) • In a Catalyst5000 family switch with redundant Supervisor EngineII modules and one or more ATM modules, if you download a software image to an ATM module and the active supervisor engine is reset before the ATM module comes online, the ATM image is corrupted and the output of the show test command for the module shows “Flash-CheckSum Failure.
Open and Resolved Caveats in Software Release 4.5(1) • In some cases, enabling IGMP snooping on a switch with a Supervisor EngineIII causes the switch to reset. The problem occurs when one of these special multicast addresses is used for normal multicast data traffic: 01-00-5e-00-00-01 01-00-5e-00-00-02 01-00-5e-00-00-04 01-00-5e-00-00-05 01-00-5e-00-00-0d This problem is resolved in software release4.5(1).
Open and Resolved Caveats in Software Release 4.5(1) • The 64-bit Rx and Tx unicast packet counters are reported incorrectly for these modules: – WS-X5005, WS-X5006, WS-X5009—Supervisor EngineI module uplink ports – WS-X5010—24 port 10 BASE-T (Telco connector) – WS-X5011—12-port 10BASE-FL MMF (ST connector) – WS-X5013— 24 port 10BASE-T (RJ-45 connector) – WS-X5113—12-port 100BASE-TX (RJ-45 connector) This problem is resolved in software release4.5(1).
Open and Resolved Caveats in Software Release 4.4(1) • In some cases, on a switch with both BackboneFast and UplinkFast enabled, the show spantree mod_num/port_num command output shows that a port is in forwarding mode, but in reality the port is in listening mode. As a result, all data traffic received on the port is discarded. Workaround: Disable and reenable the affected port. This problem is resolved in software release4.5(1).
Open and Resolved Caveats in Software Release 4.4(1) • In some cases, after a switchover from the active to the standby supervisor engine, the SPAN destination port might not function correctly.
Open and Resolved Caveats in Software Release 4.4(1) • In some cases, after a switchover from the active (slot1) to the standby (slot2) supervisor engine, the uplink ports on the previously active supervisor engine (slot1) fail to come online. You might see this message: %SYS-3-PORT_SSUPFAIL:Failed to bring up ports on standby supervisor Workaround: Disable the standby ports using the set standbyports disable command and then reenable them using the set standbyports enable command.
Open and Resolved Caveats in Software Release 4.4(1) • In some cases, when you connect a port on the 24-port 10/100 BASE-TX Fast Ethernet module (WS-X5225R) to an end station, the port might loop data back to itself. If spanning tree is disabled on the port, this problem can negatively affect switch performance. If spanning tree is enabled, the port is automatically disabled.
Open and Resolved Caveats in Software Release 4.4(1) • When a Catalyst 5000 family switch learns a MAC address on a port of the Gigabit EtherChannel module (WS-X5410), an ATM LANE module installed in the same chassis might be unable to respond to LE-ARP requests for that MAC address. As a result, all traffic for this MAC address is forwarded through the BUS rather than over a data direct VC, resulting in poor network performance. This problem is resolved in software release4.4(1).
Open and Resolved Caveats in Software Release 4.3(1) • When you enter the set port protocol group command, the command functions normally and is saved in NVRAM, but does not appear in the output of the show config command. This problem is resolved in software release4.4(1).
Open and Resolved Caveats in Software Release 4.3(1) Open Caveats in Software Release 4.3(1) Note For a description of caveats resolved in software release 4.3(1), see the “Resolved Caveats in Software Release4.3(1)” section on page59 . This section describes open caveats in software release4.3(1). Caution If your switch contains an ATM module running Token Ring LANE software, you must install Token Ring LANE software release 70.
Open and Resolved Caveats in Software Release 4.3(1) • In certain situations, attempts to create or modify a VLAN using SNMP fail. Workaround : Create or modify the VLAN from the CLI. (CSCdk01511) Note CSCdk01511 has not been seen in later releases. • In some cases, if you change the VLAN assignment of ports in a Fast EtherChannel, some ports are placed in the errdisable state and the channel is not renegotiated. The correct behavior is that the channel is torn down and renegotiated.
Open and Resolved Caveats in Software Release 4.3(1) • After a topology change occurs in a Token Ring environment, when STP reconverges, source-routed frames originating from a Catalyst 5000 family Token Ring module (WS-X5030 or WS-X5031) are not forwarded across an ISL trunk link to another switch. Non-source-routed frames are forwarded correctly. Workaround: Enter the clear cam dynamic command on the affected switches.
Open and Resolved Caveats in Software Release 4.3(1) • If you configure Fast EtherChannel on the Supervisor Engine III dual-port fiber-optic uplink module (WS-U5533-FEFX-MMF or WS-U5535-FEFX-SMF) and the link in one direction on one of the ports fails so that receive (Rx) traffic is no longer received on that port, that port incorrectly continues to transmit traffic. The correct behavior is that the port should be disabled, allowing all traffic to be transmitted over the second link in the bundle.
Open and Resolved Caveats in Software Release 4.3(1) • When upgrading to software release 4.2(1) from a previous release, if you download the software image file and then hot insert a second supervisor engine before you reset the system, the standby supervisor engine does not synchronize with the primary. This problem is resolved in software release4.3(1).
Open and Resolved Caveats in Software Release 4.3(1) • On Gigabit Ethernet ports, if autonegotiation is disabled and the link fails in only one direction, only the port losing the receive (Rx) signal brings its link down; the other port incorrectly keeps the link up. This problem is resolved in software release 4.3(1). (CSCdk48954) • Some counters might not restart at one again after reaching their maximum value. This problem is resolved in software release 4.3(1).
Open and Resolved Caveats in Software Release4.2(2) • On 10 BASE-T Ethernet modules, if a port is assigned to a particular VLAN and is configured as the SPAN source, when you change the VLAN assignment for that port, the port might stop transmitting traffic. This problem is resolved in software release4.3(1). (CSCdk25510) • In some cases, under heavy traffic (close to 99 percent), the system might generate a Switching Bus Timeout error, causing the switch to reset.
Open and Resolved Caveats in Software Release4.2(2) Open Caveats in Software Release 4.2(2) Note For a description of caveats resolved in software release 4.2(2), see the “Resolved Caveats in Software Release4.2(2)” section on page65. This section describes open caveats in software release4.2(2).
Open and Resolved Caveats in Software Release4.2(2) • In some cases, when you open a Telnet session to a Catalyst 5000 family switch from a Windows95 PC and then attempt to configure the switch using the configure network command, the Telnet session hangs. Workaround: Connect to the switch through the console port and then configure the switch from the network using the configure network command.
Open and Resolved Caveats in Software Release4.2(2) These errors can occur when there is a port-duplex misconfiguration (both ends of the link are not configured for the same duplex mode) or when the attached cable is not to specification (too long or of the wrong type). If a port has been automatically disabled, make sure the duplex configuration is the same on both ends of the link, verify that the cable is within specification, and then reenable the port using the set port enable command.
Open and Resolved Caveats in Software Release4.2(1) • In certain cases, if there are multiple ports assigned to the same TrCRF VLAN on different modules in a Catalyst 5000 family switch, and an ATM LAN emulation client (LEC) is one of those ports, Token Ring source-route switching might not forward data correctly.
Open and Resolved Caveats in Software Release4.2(1) • In some cases, when you attempt to use the CiscoView Device Configuration window to modify the IP routing table on a Catalyst 5000 family switch, the change is not made on the switch correctly. If you attempt to change the ipRouteNextHop, the value is not changed. If you attempt to change the ipRouteDest, a new table entry is added instead of the old value being changed.
Open and Resolved Caveats in Software Release4.2(1) • In a chassis with redundant Supervisor Engine III modules with NFFCs and the 24-port 10/100 BASE-TX Fast Ethernet module (WS-X5225R), you must have an uplink module installed in the supervisor engine in slot2. Without an uplink module in the supervisor engine in slot2, the synchronization between the active and standby supervisor engines might fail.
Open and Resolved Caveats in Software Release4.2(1) • When you set the BOOT environment variable using SNMP, the trailing semicolon (;) is not appended correctly, which can cause an error. This problem is resolved in software release 4.2(1). (CSCdk36756) • In some cases, after a module comes online, ports configured as a Fast or Gigabit EtherChannel bundle (in on mode) do not form a channel. Workaround : Reenter the set port channel mod_num/port_list on command.
Open and Resolved Caveats in Software Release4.1(3) • When UplinkFast is enabled on a switch with a supervisor engine with an EARL daughter card installed, the switch might respond slowly to CLI commands and software image downloads. However, switch performance and spanning tree processing are not affected. This problem is resolved in software release 4.2(1).
Open and Resolved Caveats in Software Release4.1(2) Resolved Caveats in Software Release 4.1(3) Note For a description of open caveats in software release 4.1(3), see the “Open Caveats in Software Release4.1(3)” section on page71 . This section describes caveats resolved in software release4.1(3): • Under heavy traffic conditions, ports 1–24 (or ports 25–48) of the 48-port, 10 BASE-T Ethernet module (WS-X5012) might stop transmitting frames. This problem is resolved in software release4.1(3).
Open Caveats in Software Release4.1(1) Resolved Caveats in Software Release4.1(2) Note For a description of open caveats in software release 4.1(2), see the “Open Caveats in Software Release4.1(2)” section on page72. This section describes caveats resolved in software release 4.1(2): If you attempt to upgrade the software on a Catalyst 5500 chassis with redundant Supervisor EngineIIIs from software release 3.X to software release 4.
Usage Guidelines and Restrictions Caution If you enable numerous memory-intensive features concurrently (such as VTP pruning, VMPS, EtherChannel, and RMON), or if there is switched data traffic on the management VLAN, the maximum number of supported logical ports is reduced. Note • Count each port in an EtherChannel port bundle independently (do not count the bundle as a single port).
Usage Guidelines, Restrictions, and Troubleshooting Caution • If you plan to use the Gigabit EtherChannel module (WS-X5410) with Supervisor Engine I or II or in a Catalyst 5000 series chassis, use supervisor engine software release 4.3(1) or later in conjunction with Gigabit EtherChannel module software release 4.3(1) or later. This hardware was not fully tested with the Gigabit EtherChannel module in earlier releases.
Usage Guidelines, Restrictions, and Troubleshooting System and Supervisor Engine This section contains usage guidelines, restrictions, and troubleshooting information that apply to the supervisor engine and to the switch at the system level.
Usage Guidelines, Restrictions, and Troubleshooting Modules and Switch Ports This section contains usage guidelines, restrictions, and troubleshooting information that apply to modules and switch ports. • To avoid a broadcast storm on Catalyst 5500 switches with a Supervisor Engine III and NFFC, do not insert a WS-X5030 Token Ring module in slots 9 through 12 while the switch is in service. Reset the switch after inserting a WS-X5030 Token Ring module in slots 9 through 12.
Usage Guidelines, Restrictions, and Troubleshooting • Whenever you connect a Catalyst 5000 family port that is set to autonegotiate to an end station or another networking device, make sure that the other device is configured for autonegotiation as well. If the other device is not set to autonegotiate, the Catalyst 5000 family port will remain in half-duplex mode, which can cause a duplex mismatch resulting in packet loss, late collisions, and line errors on the link.
Usage Guidelines, Restrictions, and Troubleshooting Transceivers This section contains usage guidelines, restrictions, and troubleshooting information that apply to transceivers. • If you experience trouble with a port that has an MII transceiver attached to it, check that the transceiver jumpers are set properly. • If an MII transceiver is plugged in at an angle, the Catalyst5000 family switch might stop transmitting data. To recover, reseat the MII transceiver so that it is not seated at an angle.
Usage Guidelines, Restrictions, and Troubleshooting Caution • A Catalyst family switch should be the root for all VLANs, especially VLAN1. In order to recover from an extended broadcast storm caused by a faulty device in a network, Catalyst family switches reset blocked ports. To ensure recovery, all Catalyst family switches in the network should perform this function at the same time by sending synchronization packets on VLAN 1.
Usage Guidelines, Restrictions, and Troubleshooting VTP, VLANs, and VLAN Trunks This section contains usage guidelines, restrictions, and troubleshooting information that apply to VTP, VLANs, and VLAN trunks. • Although the Dynamic Trunk Protocol (DTP) is a point-to-point protocol, some internetworking devices might forward DTP frames.
Usage Guidelines, Restrictions, and Troubleshooting SPAN This section contains usage guidelines, restrictions, and troubleshooting information that apply to the Switch Port Analyzer (SPAN). • If you configure a SPAN destination port with the inpkts disable option (the default), normal incoming traffic on the port is not forwarded. However, if you reset the module on which the SPAN destination port is configured, the port will forward normal incoming traffic after the module comes online.
Documentation Updates for Software Release4.5 Documentation Updates for Software Release 4.5 This section describes caveats for the Catalyst5000 family software release4.5 documentation. These changes will be included in the next update to the documentation. The April 1999 version of the Catalyst 5000 Series Module Installation Guide incorrectly includes information about the two-slot, 48-port 10/100BASE-TX Fast Ethernet switching module (WS-X5239-RJ21) with RJ-45 connectors.
Documentation Updates for Software Release4.2 Documentation Updates for Software Release 4.2 This section describes caveats for the Catalyst5000 family software release4.2 documentation. These changes will be included in the next update to the documentation.
Additional Documentation • In the Catalyst 5000 Series Command Reference publication, the set snmp rmon command section has been updated. The “Usage Guidelines” section should contain the following information: – RMON is enabled for Ethernet, Fast Ethernet, Gigabit Ethernet, and Token Ring switch ports. – When RMON is enabled, the supported RMON groups for Ethernet, Fast Ethernet, and Gigabit Ethernet ports are Statistics, History, Alarms, and Events, as specified in RFC 1757.
