Release Notes for Catalyst 4500 Series Software Release 7.x

OL-1983-28

Open and Resolved Caveats in Software Release 7.1(2a)

• The switch might crash if VTP is configured in client or server mode and connected to a

Catalyst 4500 series switch with a Supervisor Engine III.

Workaround: Configure VTP to use transparent mode. This problem is resolved in software release

7.2(1). (CSCdw41158)

• In certain configurations, the switch might drop IGMP reports before passing the reports to the

router. If multicast functionality is based on CGMP, it will be affected.

Workaround: Manually add a multicast static entry pointing to the CGMP router on the switch that

is dropping IGMP reports. This problem is resolved in software release 7.2(1). (CSCdw60550)

• You do not need to reload the switch to clear a faulty status for a supervisor engine. If the supervisor

engine still shows up as faulty, there is another problem in the system, possibly a bad fan or a

temperature alarm. This problem is resolved in software release 7.2(1). (CSCdw62053)

• On a Catalyst 2948G or 2980G switch, port negotiation or flow control commands are not saved in

the configuration file. You can see this when you issue the show config all command. This does not

affect the functionality of the switch, but if you reload the switch with a TFTP configuration file,

the port negotiation and port flow-control configuration settings will be lost. The configuration

remains intact in the NVRAM, and an ordinary reboot will not affect the configuration. This issue

is not apparent on Catalyst 4500 series switches. This problem is resolved in software release 7.2(1).

(CSCdw44268)

• You cannot configure the switch using the set spantree root command in software release 7.x. This

problem is resolved in software release 7.2(1). (CSCdw76786)

Open and Resolved Caveats in Software Release 7.1(2a)

These sections describe the open and resolved caveats in supervisor engine software release 7.1(2a):

• Open Caveats in Software Release 7.1(2a), page 47

• Resolved Caveats in Software Release 7.1(2a), page 48

Open Caveats in Software Release 7.1(2a)

These caveats are open in software release 7.1(2a):

• A Catalyst 4500 series switch running in the access layer may display loop guard-inconsistent

messages if a topology change occurs in corresponding designated switches that have a high number

of spanning tree instances. The switch recovers on its own and does not cause a network outage.

(CSCdz65842)

• When connecting NIC: SMC 8432BT with a DEC 21041-AA chipset on a PC Compaq Desktop

6xxxx to a 2980A-G switch at 10/HD, you might experience Align/FCS/Rcv-errors. (CSCdv79989)

• HP TopTool Remote Control Card v2.0 will join or leave the group approximately every 1 minute.

(CSCdw00897)

• A router in HSRP standby status is changed to active status. When status is restored, it does not go

back to standby status from active status.

Workaround: The router recovers if the interface on the HSRP standby side is set to shutdown or

no shutdown. (CSCdw32957)

• The switch does not send dummy frames with known dynamic MAC addresses if one of the uplinks

is configured as GEC and it goes down. (CSCdw34521)
