Changes to the Release Notes Changes to the Release Notes This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15454 SDH Release 4.1.3 since the production of the Cisco ONS 15454 SDH System Software CD for Release 4.1.3. The following changes have been added to the release notes for Release 4.1.3. Changes to Caveats The following caveats have been added.
Caveats G1K-4 cards with the CLEI code of WM5IRWPCAA (manufactured after August 2003) are expected to support CWDM and DWDM GBICs, but final qualification testing was not complete at press time. The online version of the 4.1 user documentation and release notes will be updated to reflect the final qualification status of CWDM and DWDM GBICs on the G1K-4 card with the CLEI code of WM5IRWPCAA, when this information is available. Note Operating temperature of the DWDM GBICs is -5 degrees C to 40 degrees C.
Caveats Upgrades DDTS # CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1 Caution Before you upgrade to Release 4.1.3 from Release 4.0, 4.0.1, or 4.1, you must read this caveat and run the SDH Circuit Repair Utility (VcCheck) provided on the software CD (also available on CCO). The XCVXL card on the ONS 15454 SDH allows the intermixing of VC12 and VC3 payloads within a single VC4.
Caveats DDTS # CSCec46228 Rarely, traffic on the DS3i-N-12 card might incur a hit when the active TCC2 is pulled. Removing the active TCC2 can cause timing hits and disrupt communication between cards, causing protection switches. To avoid this issue, instead of pulling the active TCC2, issue a manual switch, then pull the TCC2 once it has become standby. This issue will be resolved in Release 4.6.
Caveats Ethernet Polarity Detection The TCC2 does not support Ethernet polarity detection. The TCC+ and TCCI both support this feature. If your Ethernet connection has the incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), the TCC+/I will work, but the TCC2 will not. In this event, a standing condition, “LAN Connection Polarity Reverse Detected” (COND-LAN-POL-REV), will be raised (a notification will appear on the LCD, and there will be an alarm raised).
Caveats Table 1 SDH Data Cards that are SONET Compatible Product Name Description 15454E-ML100T-12 10/100 Mbps Ethernet card, 12 ports, RJ-45, L2/L3 switching, SDH/ETSI system, includes console cable 15454E-ML1000-2 1000 Mbps Ethernet card, 2 SFP slots, L2/L3 switching, SDH/ETSI system Table 2 SONET Data Cards that are SDH Compatible Product Name Description 15454-G1000-4 4 Port Gigabit Ethernet 15454-E100T-G 10/100BT, 12 circuit, compatible w/ XC, XCVT and XC10G 15454-E1000-2-G Gigabit Et
Caveats a PLM against traffic that passes through a node, though it will appear to raise a PLM against traffic with the wrong C2 byte that is terminated on an electrical card within the node. It is not known at this time when or if this issue will be resolved. Note Optical cards do ensure that the C2 byte is nonzero (Equipped), and will raise a UNEQ condition if the C2 byte is 0 (Unequipped).
Caveats Single-card EtherSwitch Each E100/E1000 card can be configured as a single-card EtherSwitch configuration to allow VC4-4c of bandwidth to be dropped at each card. The following scenarios for provisioning are available: VC4-4c VC4-2c, VC4-2c VC4-2c, VC4, VC4 VC4, VC4, VC4, VC4 When configuring scenario 3, the VC4-2c must be provisioned before either of the VC4 circuits.
Caveats DDTS # CSCea36829 The broadcast packet count is always 0 for the SPR interface. The ML100 and ML1000 hardware does not support counting broadcast packets. This issue will not be resolved. DDTS # CSCeb21996 When the POS interface is removed from SPR due to a defect, while SPR is configured in immediate mode, the defect type may not be reported. This only occurs if the defect is set and clears in less then 50 ms.
Caveats DDTS # CSCdz87944 Error messages indicating “Stuck Ucode” and “MDA_INTERNAL_ERROR” occur when routing 64-byte VLAN tagged frames at line rate. For VLANs, use bridging instead of routing. This issue will be resolved in a future release. DDTS # CSCea01675 Packets without an 802.1q VLAN tag are classified as COS 0. This issue will be resolved in a future release. DDTS # CSCea11742 When a circuit between two ML POS ports is provisioned OOS, one of the ports might erroneously report TPTFAIL.
Caveats DDTS # CSCin35960 POS ingress classification based on IP precedence does not match the packets when inbound policy map classifying based on IP precedence is applied to the POS interface, which is configured for HDLC or PPP encapsulation. To avoid this issue, use LEX encapsulation (default) or, at the Ethernet ingress point, mark the COS based on an IP precedence classification, then classify based on the COS during POS ingress. This issue will be resolved in a future release.
Caveats A companion advisory that describes the vulnerability for products that do not run Cisco IOS software is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-nonios.shtml. This issue is resolved in Releases 2.3.5, 4.1.4 and 4.6.2. DDTS # CSCeb63327 The High Temperature Alarm is raised at 50 degrees Celsius. This is, however, not optimal on an Itemp rated system, which can tolerate up to 65 degrees Celsius.
Caveats Changed Default Alarm Severities The following alarm severities have changed for Release 4.1.x.
Caveats DDTS # CSCea13593 DRI configuration rules require limits on multiple drops. However, in an ONS 15454 SDH DRI topology, a unidirectional circuit can be created from one ring to another with two drops at the destination node. This issue will be resolved in Release 5.0. DDTS # CSCdz90733 PCA traffic can remain down after restoring the incorrect database and then restoring the correct database to the node. To avoid this issue, exercise care in database restoration.
Caveats • Enable OSPF on the LAN • Enable Firewall • Craft Access Only When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 15454 SDH proxy ARP service assumes that all nodes are participating in the service. This situation can also occur immediately after the aforementioned features are enabled. Other hosts on the Ethernet segment (for example, the subnet router) may retain incorrect ARP settings for the ONS 15454 SDHs.
Caveats DDTS # CSCdw38283 If a node has one good BITS reference and is running in a normal state, and you configure a second BITS reference, then reconfigure the second reference within 30 seconds of applying the first configuration, the node will enter FAST START SYNC mode. To avoid this problem, wait a minute before configuring the second reference a second time. This issue is a hardware limitation, and there are no current plans to resolve it.
Caveats MS-SPRing Functionality DDTS # CSCec32195 Rarely, in a two fiber MS-SPRing with STM64 span cards and a VC3 circuit running across DS3I drop cards, if you upgrade to Release 4.1.3 the TU-LOP alarm might be falsely reported against the STM64 trunk card even though traffic is passing fine. It is not known when or when this issue will be resolved.
Caveats DDTS # CSCea02986 In MS-SPRing configurations multiple node deletions and additions on a ring in quick succession can cause PCA traffic to go down. If this occurs, apply a Force Ring switch on the effected nodes. This issue will be resolved in Release 5.0. DDTS # CSCdz66275 When creating a MS-SPRing from the network view, the node default values for reversion are not initially used.
Caveats To see this issue, on a node participating in a two fiber MS-SPRing with PCA circuits terminating at the node over the two fiber MS-SPRing, cause an SF-R by failing the receive fiber in one direction (say, west). Then issue a lockout span in the other direction (in our example, east). Since the lockout span has higher priority than the SF-R, the ring switch should clear and PCA traffic should be restored on spans without a fiber fault. The ring switch does clear, but PCA traffic does not restore.
Caveats Step 1 To isolate the failed node, issue a force switch toward the failure node from the adjacent east and west nodes. Step 2 If more than one node has failed, restore the database one node at a time. Step 3 After the TCCi has reset and booted up, release the force switch from each node. SNCP Functionality DDTS # CSCeb37707 With a VT SNCP circuit, if you inject signals with a thru-mode test set into one path of the circuit in a particular order, you may not see the appropriate alarms.
Resolved Caveats for Release 4.1.3 Documentation VcCheck Readme File Changes The VcCheck readme file on the CCO Software Download Page contains the following changes, updated from the version on the software CD for Release 4.1.3. The readme file on CCO replaces the readme file on the software CD. Setting the Java environment variable: Windows: From the command prompt, enter: USE_JAVA=C:\Program Files\JavaSoft\JRE\1.3.
Resolved Caveats for Release 4.1.3 Line Cards DDTS # CSCea16455, CSCea37089, CSCea37185 Malformed SNMP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 4.6, and maintenance Releases 4.0.1, 4.0.3, and 4.1.3. DDTS # CSCed05846 In Releases 4.0, 4.0.1, and 4.1 the standby TCC+, TCC2, or XTC card might reset automatically.
Resolved Caveats for Release 4.1.3 ML Series DDTS # CSCin25238 If you configure Fast EtherChannel and POS-channel in the same bridge group, during system boot, the Fast EtherChannel or POS-channel configuration may be lost and following error message displayed: Interface FastEthernet1 is attempting to join Port-channel1. But Port-channel1 belongs to bridge-group 1 which has another FE(C) member in it. FEC + FE(C) is not allowed in the same bridge group. Please change your configuration and retry.
Resolved Caveats for Release 4.1.3 the characters from 5th position onwards. While node was operating in release 4.1.3, create the users with 'A' at 5th position of the username. Upgrade the node to any other release. After the upgrade, only the first 4 characters are retained as username. This issue is serious enough to cause a network to be unreachable during an outage or other service impacting occasions. Workaround: Do not add a username with character 'A' in 5th position.
New Features and Functionality SNCP Functionality DDTS # CSCec04550 In a SNCP configuration, upon detecting a double-path failure with UNEQ-P, the UNEQ-P on the protect path is not reported. This issue is resolved in Release 4.1.3. DDTS # CSCec14995 In a non-revertive SNCP configuration, when a double failure is detected on both paths with UNEQ-P or AIS-P, upon clearing the protect path defect, the UNEQ-P or AIS-P alarm may remain stuck on the working path for the node.
New Features and Functionality • No hardware changes: Only requires ONS 15454 Release 4.1.x, which includes the new IOS configuration. • Increased number of supportable VLANs and MAC addresses on the ring. • A scalable, inter-ring protection mechanism for increased network resiliency. • The addition of RPR does not remove any Release 4.0 functionality. RPR features are enabled via a new set of configuration commands.
New Features and Functionality Gigabit Ethernet Transponder The Gigabit Ethernet Transponder is a software enhancement to existing G-series Ethernet cards that allows these cards to support transponder functionality. The following features support Gigabit Ethernet Transponder functionality for Release 4.1.x. Note In this section, unless otherwise mentioned, all items apply equally to both G1000-4 cards and G1K-4 cards. Some capabilities also apply to G1000-2 cards for the ONS 15327.
New Features and Functionality This applies only to the ONS 15454-based G-series cards (G1000-4 and G1K-4). This feature also includes the ability of the cards to operate (when in transponder mode) independent of the cross connect cards and even operate without any cross connect cards in the shelf. When at least one port is provisioned in a transponder mode, the entire card will be in transponder mode. When SONET/SDH circuits are provisioned on a card, the card is said to be in normal/SONET/SDH mode.
