Release Notes for Catalyst5000 Family Software Release4.x
OL-2306-01
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.
• NetFlow Data Export—Allows a summary of intersubnet Layer 3 traffic statistics for all expired
flows to be periodically exported to a network management data collector.
• Standby Supervisor Engine Port Usage—Allows the uplink ports on both the active and standby
supervisor engine to be active at the same time. Prior to software release 4.1, the uplink ports on the
standby supervisor engine were always in standby mode (inactive).
• IEEE 802.1Q VLAN Trunking—Allows you to support multiple VLANs across a single trunk link
between two switches using 802.1Q packet encapsulation. This feature is supported only on modules
that support 802.1Q encapsulation.
• Multiple Default IP Gateways—Allows you to configure up to three default IP gateways. If one
gateway is not reachable, another gateway becomes the default.
• SNMP Trap Message Enhancements—Provides additional information with certain SNMP trap
messages, including:
– Spanning Tree Topology Enhancement—Provides a Cisco-defined SNMP trap notification and
syslog message for a spanning tree topology change.
– Configure Change Syslog Message and SNMP Trap—Sends a syslog message and/or SNMP
trap indicating who is making a configuration change (via SNMP or the CLI): Terminal Access
Controller Access Control System Plus (TACACS+) user name, Domain Name Service (DNS)
name, IP address, or console port.
• Remote Monitoring 2 (RMON2) Configuration Group—Adds support, probe capabilities, software
revision, and hardware revision for the RMON2 configuration group trap destinations Management
Information Base (MIB) defined in RFC2021.
• DNS Device Name Usage—Allows you to set the system name to be configured automatically based
on the IP address of the switch.
• show port capabilities command—Allows you to determine the capabilities of the modules and
ports in a switch.
• Configuration File Management—Allows you to copy a configuration file to or from a file on a flash
device (bootflash, slot0, or slot1) or a TFTP server with the config keyword of the copy command.
• New hardware supported:
– 24-port 10/100BASE-TX Ethernet Module—Provides 24 10/100BASE-TX Ethernet ports;
supports ISL and IEEE 802.1Q trunking, broadcast suppression in hardware, 802.3x flow
control, EtherChannel port aggregation, and a local rewrite engine. (WS-X5225R)
– 12-port 100BASE-FX Ethernet Module—Provides 12 100BASE-FX Ethernet ports; supports
ISL and 802.1Q trunking, broadcast suppression in hardware, 802.3x flow control,
EtherChannel port aggregation, and a local rewrite engine. (WS-X5201R)
– Gigabit Ethernet Uplink for Supervisor Engine III—Provides two 1000BASE-SX Gigabit
Ethernet ports; supports ISL and 802.1Q trunking. This uplink module does not support Gigabit
EtherChannel port aggregation. (WS-U5534)
