Release Notes for Catalyst 4500 Series Software Release 7.x

OL-1983-28

Open and Resolved Caveats in Software Release 7.2(1)

Open Caveats in Software Release 7.2(1)

These caveats are open in software release 7.2(1):

• 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 you use Merit Radius Server (a freeware application), and enter an invalid username to Telnet

to a switch configured to use RADIUS authentication and a RADIUS server is available, the switch

will reboot.

Workaround: Use Cisco Secure Radius Server. (CSCdx01532)

• Ports on a Catalyst 2980G-A switch can stop receiving packets when connected to some hosts or

ports with high ESD applied to them. This could happen in environments where cables are allowed

to charge up to a high voltage. The ports will not receive any good packets. The Rx good packet

count will not increase, and some error counters can increase when packets are received from

neighboring hosts and switches. The symptoms are only temporary and will not damage your

hardware. This problem is resolved in software releases later than 7.2(1); however, it is disabled by

default.

Workaround: Reset the switch. (CSCdw37422)

• ARP packets from an AIX server connected to the Catalyst 4000 with Gigabit EtherChannel (GEC)

links are not received. This problem is intermittent. (CSCdv15018)

Resolved Caveats in Software Release 7.2(1)

These caveats are resolved in software release 7.2(1):

• CISCO-STACK-MIB SNMP controlled configuration download is not functioning correctly. This

problem is resolved in software release 7.2(1). (CSCdx04874)

• When you are removing the fiber cable on a forwarding port, UplinkFast works fine and data traffic

recovers after a few seconds; but when the whole module is disabled, it takes an average of

25 seconds for data traffic to recover. This problem is resolved in software release 7.2(1).

(CSCdt41259)

• Two or more Catalyst 4003 switches configured for Remote Span (RSPAN) might experience a

packet storm when one switch has active source and destination RSPAN ports, and the other has

active source RSPAN ports.

Workaround: Do not configure the local switch (switch with a destination port) with an RSPAN

source port. This problem is resolved in software release 7.2(1). (CSCdx10678)

• Under certain circumstances, it is possible that the UplinkFast feature can cause high CPU

utilization on a Catalyst 4500 series switch running MST or MISTP. If high CPU utilization does

occur, the CPU utilization of the ufastMcast process will remain high until the switch is reloaded.

This problem is resolved in software release 7.2(1). (CSCdu61791)

• The switch does not respond correctly to community strings that contain a “/”. This problem is

resolved in software release 7.2(1). (CSCdx03088)
