Deferred Software Releases

---

Caution Catalyst 4000 family supervisor engine software release 5.1(1) was deferred due to caveat CSCdm09827. When you upgrade the switch software to release 5.1(1) from any 4.x release, the switch configuration is lost. This problem is resolved in software release 5.1(1a).

---

If you intend to upgrade to release 5.x from any 4.x release, we strongly recommend that you upgrade directly to release 5.1(1a) or later, skipping release 5.1(1). Always back up the switch configuration file before upgrading or downgrading the switch software to avoid losing all or part of the configuration.

If you are already running software release 5.1(1), there is no need to upgrade to 5.1(1a).

Power Supply Requirements

The Catalyst 4006 switch requires dual power supplies.

Release 5.x Memory Requirements

Table 1 shows the specific memory requirements for running software release 5.x on the Catalyst 4000 family Supervisor Engine I.

Table 1 Software Release 5.x Supervisor Engine Memory Requirements

Software Release	Supervisor Engine I Memory Requirements	Supervisor Engine II Memory Requirements
Software release 5.1(2a) and earlier	32-MB RAM	—
Software release 5.2(1) and later	64-MB RAM	—
Software release 5.4(1) and later	64-MB RAM	64-MB RAM

If your Supervisor Engine I has less than 64 MB RAM, you can add more memory by ordering the 32-MB DIMM RAM upgrade (Cisco product number MEM-C4K-32-RAM=) for the Catalyst 4000 family Supervisor Engine I.

Product and Software Version Matrix

This section contains configuration matrixes to help you order Catalyst 4000 family products. Table 2 lists the minimum supervisor engine version and the current recommended and default supervisor engine version for Catalyst 4000 family modules and chassis.

1 The 5.5(4) and later CiscoView releases requires JPI (Java Plug-in) 1.3 in the browser. These releases are incompatible with 5.5(3) CiscoView and earlier releases, which require JPI 1.2.2. 2 All 5.x CiscoView images have been deferred due to CSCdu25881. You should upgrade to CiscoView release 5.5(8a)CiscoView. The CiscoView that is embedded in Catalyst software will not work after May 11, 2001, because the digital certificates used to sign the Java classes have expired. You should upgrade to release 5.5(8a)CiscoView. For workarounds and additional information, see the following URL: http://www.cisco.com/warp/public/770/fn13613.shtml

New Features for Supervisor Engine Software Release 5.4

This section describes the new features available in software release 5.4.

Hardware Features

This section lists the new hardware features available in software release 5.4.

•Catalyst 4006 chassis (WS-C4006-S2)

•Catalyst 4006 Supervisor Engine (WS-X4013)

•Catalyst 2980G 80-port 10/100/1000 Fixed Configuration Switch (WS-C2980G)

•48-port 10/100-Mbps Fast Ethernet Switching Module (WS-X4148-RJ21)

•12-port 1000BASE-T Gigabit Ethernet Switching Module (WS-4412-2GB-TX)

Software Features

This section lists the new software features available in software release 5.4.

•Unidirectional Link Detection Protocol (UDLD) enhancements—With supervisor engine software releases 5.4(3) and later, you can specify the message interval between UDLD messages. Previously, the message interval was fixed at 60 seconds. With a configurable message interval, UDLD reacts much faster to link failures.

Additionally, releases 5.4(3) and later have UDLD aggressive mode, which is recommended only for point-to-point links between Cisco switches running software release 5.4(3) or later. UDLD aggressive mode is disabled by default. When aggressive mode is enabled and a port on a bidirectional link stops receiving UDLD packets, UDLD tries to reestablish the connection with the neighbor. After eight failed retries, the port enters an errdisable state.

In order to prevent spanning tree loops, set normal UDLD message intervals to 15 seconds. This setting is fast enough to shut down a unidirectional link before a blocking port transitions to forwarding state (when default spanning tree parameters are used).

Enabling UDLD aggressive mode provides additional benefits in the following cases:

–One side of a link has a port stuck (both Tx and Rx)

–One side of a link remains up while the other side of the link has gone down

In these cases, UDLD aggressive mode disables one of the ports on the link and stops dropping traffic. Even with aggressive mode disabled, there would have been no risk for a broadcast storm due to a spanning tree loop in this situation, as one port is unable to pass traffic in both directions.

---

Note Before using UDLD, read the "Open and Resolved Caveats in Software Release 5.5(1)" section, and note the recommendations listed for caveat CSCdr50206.

---

For detailed information on configuring the message interval and UDLD aggressive mode, refer to the online version of the Software Configuration Guide—Catalyst 5000 Family, 4000 Family, 2928G Series, 2948G, and 2980G Switches, Release 5.4.

•The Catalyst Web Interface (CWI) is a browser-based tool that you can use to configure the Catalyst 6000 family, 5000 family, and 4000 family switches. It consists of a graphical user interface (GUI) that runs on the client (a Catalyst version of CiscoView 5.0) and a Hypertext Transfer Protocol (HTTP) server that runs on the switch. A GUI alternative to the CLI and SNMP interfaces, the CWI provides a real-time graphical representation of the switch and detailed information such as port status, module status, chassis type, and installed modules. The CWI uses HTTP to download CiscoView from the server to the client.

For information on installing and using the CWI, refer to the Catalyst 6000 Family, 5000 Family, and 4000 Family Switches Web Interface Installation and Configuration Note.

•Dynamic Host Configuration Protocol (DHCP) client—Allows the switch to obtain its IP configuration automatically from a DHCP server.

•Configure from Flash at startup—Allows the switch to run one or more configuration files stored in Flash memory when the switch is powered on or reset.

•Flexible PAgP—Provides enhancements and new functionality to existing EtherChannel port bundling features, including non-contiguous port bundles, port bundles of up to eight ports, and port bundles across multiple modules.

•Port security enhancements—Provides additional port security features, such as restricting traffic on a secure port instead of shutting down the port, and allowing multiple secure addresses on a port.

•UDLD on copper—Provides support for the UDLD protocol on copper media.

•Kerberos Telnet—Provides support for encrypted Telnet sessions on the switch using Kerberos.

•Remote Copy Protocol (RCP) support—Provides an alternative method for copying system software image files and configuration files over the network, using rcp.

•Switched Port Analyzer (SPAN) enhancements—Provides a "don't learn" option to prevent a SPAN destination port with the inpkts enable option set from learning addresses from the incoming traffic.

•Open Caveats in Software Release  5.5(20)

•Resolved Caveats in Software Release  5.5(20)

Open Caveats in Software Release  5.5(20)

There are no open caveats in software release 5.5(20).

Resolved Caveats in Software Release  5.5(20)

This section describes resolved caveats in supervisor engine software release 5.5(20).

•A TTL of 32 is too low for some implementations. A TTL of 32 may decrement before the packets get out of a MPLS network. This situation can cause problems with any IP-based application. This problem is resolved in software release 5.5(20). (CSCea48092)

•The switch might incorrectly report an STP root change with the following message:

2003 Jun 09 11:42:28 EST -04:00 %SPANTREE-5-ROOTCHANGE:Root changed for Vlan Y:New 
root port n/m. New Root mac address is XX-XX-XX-XX-XX-XX. 

This is an informational message only and should not affect the operation of your switch. The workaround is to change the logging level on the SPANTREE facility down to level 4. This problem is resolved in software release 5.5(20). (CSCeb78548)

•The system does not synchronize local time through Network Time Protocol (NTP) when summertime is configured or changed. This problem is resolved in software release 5.5(20). (CSCdx42695)

•The set spantree root command does not work if the switch is already the root for the VLAN. This problem is resolved in software release 5.5(20). (CSCec13215)

There are no open caveats in software release 5.5(19).

Resolved Caveats in Software Release  5.5(19)

This section describes resolved caveats in supervisor engine software release 5.5(19).

•A Catalyst 4000 family switch with a WS-X4012 occasionally returns an invalid value of 4.29497e+09 for CPU objects cpmCPUTotal5sec and cpmCPUTotal1min. This problem is resolved in software release 5.5(19). (CSCdz42365)

•A port with port security enabled is not included in the static CAM table when an MC receiver is on the port. When the host sends an IGMP join report to the MC router, the MC router sends a CGMP join to the switch but the switch does not add the host to the static CAM table.

If there are no other hosts, the switch will flood the MC traffic and all hosts will receive the traffic. However, if just one host with port security disabled joins the group, only that host will show up in the static CAM table and all other hosts will stop receiving the MC traffic.

Workaround: Disable either port security or CGMP on the switch. This problem is resolved in software release 5.5(19). (CSCdz89564)

•Moving a host from a secured port to an unsecured port causes a security violation. This problem is resolved in software release 5.5(19). (CSCea07450)

•The show log command on a Catalyst 4006 switch does not report power supply 3 failures.

Workaround: Install a syslog server to show power supply unit failures. This problem is resolved in software release 5.5(19). (CSCdz45426)

•The multicast entry for a trunk port in a nondefault VLAN disappears when you configure permanent CAM entries on the trunk port for any VLAN other than the default VLAN and reboot the system.

Workaround: Clear the permanent CAM and reconfigure the CAM entries. This problem is resolved in software release 5.5(19). (CSCea31013)

This section describes resolved caveats in supervisor engine software release  5.5(17).

•Under rare circumstances, a Catalyst 4000 family switch will crash after receiving a corrupted VTP packet with an invalid vlan_id. The switch will recover automatically.

Workaround: There is no workaround. (CSCdy60111)

•In a Catalyst 4006 switch that is fully populated with WS-X4148 cards running software version 7.1(2), the port security shutdown timer might not work as expected and you might not be able to reenable the shutdown ports on all line cards. This problem is resolved in software release 5.5(17). (CSCdy01966)

There are no open caveats in software release 5.5(16).

Resolved Caveats in Software Release  5.5(16)

This section describes resolved caveats in supervisor engine software release  5.5(16).

•When you enter the show port and show counters commands using the CLI, FCS errors are generated, but when the SNMP object dot3StatFCSError is polled, no errors are indicated. This problem is resolved in software release 5.5(16). (CSCdx88030)

•If a static MAC address is installed using the port security feature, a flood-path can be installed instead of a unicast path. The port security feature automatically installs a static MAC address if there is a secure address configured on the port. This problem is resolved in software release 5.5(16). (CSCdy14154)

•When Spanning Tree Protocol (STP) tries to send a SCP message to set CBL for a channel port, it queries the Port Aggregation Protocol (PAgP) to get the corresponding physical ports. In some rare cases, the Network Management Protocol (NMP) gets a port that has been removed from STP (and now nontrunking) and sends an SCP message for that port which results in native VLAN inconsistencies.

Workaround: There is no workaround. This problem is resolved in software release 5.5(16). (CSCdw12370)

There are no open caveats in software release 5.5(15).

Resolved Caveats in Software Release 5.5(15)

This section describes resolved caveats in supervisor engine software release 5.5(15).

•The total number of all received error packets (as represented in the CLI by the show mac command and its associated InLost counter) is not available through SNMP because the dot3StatsInternalMacRxErrs MIB is incorrect. This problem is resolved in software release 5.5(15). (CSCdw86025)

•When a reachable host and an unreachable host are configured as syslog servers on a Catalyst 2948G switch without a default-gateway, only the first syslog message is sent to the syslog server. After clearing the unreachable host, any unsent messages are sent to the reachable host all at once.

Workaround: Clear the unreachable host from the configuration. This problem is resolved in
