Open Caveats in Software Release 7.1(1)
These caveats are open in software release 7.1(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)
• A watchdog timer exception occurred because of an infinite loop in the CIGMPFilterTable.

Resolved Caveats in Software Release 7.1(1)
This section describes caveats resolved in software release 7.1(1):
• Creating an EtherChannel consisting of ports located on different modules might not work on
Catalyst 4500 series switches.
Workaround: Upgrade the switch software. This problem is resolved in software release 7.1(1).

• If you have IP permit configured on your switch and you upgrade your switch software from a
release of 5.4.2 or earlier to any release later than 5.4.2, you will lose your IP permit entries.
However, the ip permit enable configuration will remain, and the switch might not be accessible
from Telnet; the switch might still be accessible using other protocols, such as SNMP or SSH.
Workaround: Upgrade the switch software. Before upgrading the switch software, back up the
switch configuration and disable IP permit by using the set ip permit disable command. After you
upgrade the software, enable the IP permit lists by using the set ip permit enable command, or
restore the configuration from the backup you made before performing the software upgrade. This
problem is resolved in software release 5.5(12). This problem is resolved in software release 7.1(1).
(CSCdv81793)
• If you power off a switch, or the switch loses power during the ROMMON boot process, the system
might fall back to the next image in the boot sequence. Repeating this process can lead to the system
booting to the ROMMON CLI prompt, which will require manual intervention and connecting to the
console serial port.
Workaround: Do not power cycle switches before they finish booting, or you can fix the problem
by upgrading the ROMMON. This problem is resolved in software release 7.1(1). (CSCdu45096)
