Cisco Cisco IOS Software Release 12.2(55)SE

Some access point devices are incorrectly discovered as IEEE 802.3af Class 1 devices. These access
points should be discovered as Cisco pre-standard devices. The show power inline user EXEC
command shows the access point as an IEEE Class 1 device. The workaround is to power the access
point by using an AC wall adaptor. (CSCin69533)

After you change the access VLAN on a port that has IEEE 802.1x enabled, the IP phone address is
removed. Because learning is restricted on IEEE 802.1x-capable ports, it takes approximately 30
seconds before the address is relearned. No workaround is necessary. (CSCea85312)

The Cisco 7905 IP Phone is error-disabled when the phone is connected to wall power.

The workaround is to enable PoE and to configure the switch to recover from the PoE error-disabled
state. (CSCsf32300)

When upgrading switches in a stack, the director cannot send the correct image and configuration
to the stack if all switches in the stack do not start at the same time. A switch in the stack could then
receive an incorrect image or configuration.

The workaround is to use an on-demand upgrade to upgrade switches in a stack by entering the
vstack download config and vstack download image commands. (CSCta64962)

When you upgrade a Smart Install director to Cisco IOS Release 12.2(55)SE but do not upgrade the
director configuration, the director cannot upgrade client switches.

When you upgrade the director to Cisco IOS Release 12.2(55)SE, the workaround is to also modify
the configuration to include all built-in, custom, and default groups. You should also configure the
tar image name instead of the image-list file name in the stored images. (CSCte07949)

Backing up a Smart Install configuration could fail if the backup repository is a Windows server and
the backup file already exists in the server.

The workaround is to use the TFTP utility of another server instead of a Windows server or to
manually delete the existing backup file before backing up again. (CSCte53737)

In a Smart Install network with the backup feature enabled (the default), the director sends the
backup configuration file to the client during zero-touch replacement. However, when the client is
a switch in a stack, the client receives the seed file from the director instead of receiving the backup
configuration file.

The workaround, if you need to configure a switch in a stack with the backup configuration, is to
use the vstack download config privileged EXEC command so that the director performs an
on-demand upgrade on the client.

When the backup configuration is stored in a remote repository, enter the location of the
repository.

When the backup file is stored in the director flash memory, you must manually set the
permissions for the file before you enter the vstack download config command. (CSCtf18775)

If the director in the Smart Install network is located between an access point and the DHCP server,
the access point tries to use the Smart Install feature to upgrade even though access points are not
supported devices. The upgrade fails because the director does not have an image and configuration
file for the access point. There is no workaround. (CSCtg98656)
