Release Notes for Catalyst5000 Family Software Release4.x
OL-2306-01
Open and Resolved Caveats in Software Release 4.5(5)
• The switch might reset following a show configuration command if the login banner is set through
SNMP and is longer than 200 characters without a return. This problem is resolved in software
release 4.5(6). (CSCdp65405)
• Permanent CAM entries created by MPOA are not removed when an ATM module is removed or
reset. This problem is resolved in software release 4.5(6). (CSCdm94115)
• Configuring the RMON alarm for the ATM module-related MIB object might cause Catalyst5000
family switches to stop responding to SNMP requests. This problem is resolved in software release
4.5(6). (CSCdp48766)
• If DNS lookup fails, a high rate of memory leaks occur for every DNS lookup. This problem is
resolved in software release4.5(6). (CSCdp71815)
• If you are connected to the console port on a Catalyst 5000 supervisor engine and Telnet out of the
supervisor engine, the Catalyst switch reboots with a TLB exception. To avoid this problem, do not
cut and paste a large amount of data onto the Telnet screen while Telnetting out of or sessioning into
the RSM. This problem is resolved in software release4.5(6). (CSCdp60430)
• The system might encounter an exception if all of the following conditions are met:
– RMON is enabled
– A Token Ring module exists in the device
– The system is low on free memory
To prevent this problem, disable RMON, remove the Token Ring module, or reduce the memory
usage in the device. This problem is resolved in software release4.5(6). (CSCdp57910)
• MAC addresses might be learned on invalid or nonexistent ports when CDP traffic on Fast Ethernet
channel or Gigabit Ethernet channel interfaces is received with different MAC addresses but from
the same physical port in the channel group.
Workaround: Disable CDP on the device channeling to or connecting to the Catalyst 5000 family
switch. This problem is resolved in software release4.5(6). (CSCdp55073)

This section describes open caveats in software release4.5(5).
• When using VMPS on ports connected to routers running HSRP that are not configured to use the
burned in address, the Catalyst 5000 family switch might reset when the active HSRP router is being
shut down.
