OL-22861-04
Resolved Caveats
•
CSCtf78276
A switch running Cisco IOS Release 12.2(53)SE1 stops when IEEE 802.1x authentication is
enabled.
The workaround is to apply a VLAN that the RADIUS server assigned to the switch.

Multidomain authentication (MDA) with guest VLAN or MAC authentication bypass (MAB) as a
fallback method is enabled on a switch running Cisco IOS Release 12.2(53)SE. When a non-802.1x
client is connected to a IP phone and the phone connected to a switch port shuts down and then
restarts, the client MAC address status is
drop
in the MAC address table. It takes 5 minutes for the
client to access the network.
The workaround is to use another software release, such as Cisco IOS Release 12.2(44)SE2.

This error message is displayed after copying a configuration file to the running configuration file
fails:
%Error opening system:/running-config (No such file or directory)
The output of the
dir system:/
EXEC command also does not show a running configuration file.
The workaround is to reload the switch.

After you upgrade the switch software to Cisco IOS Release 12.2(55)SE, enhanced auto-QoS
commands are generated when
–
auto-QoS is enabled on an interface
and
–
mls qos
command is not enabled on the switch
If the
mls qos
command was already enabled on the switch, enhanced auto-QoS commands are
generated only when you configure one of these commands:
–
auto qos classify
[
police
]
–
auto qos trust
{
cos
|
dscp
}
–
auto qos video
{
cts
|
ip-camera
}
Cisco IOS Release 12.2(55)SE supports implicit and explicit migration to enhanced auto-QoS
configurations.
Implicit migration to enhanced auto-QoS occurs on a switch running legacy auto-QoS when you
configure the
auto qos video
,
auto qos trust
, or
auto qos classify
command
on an interface. Global
and interface configurations on the switch migrate to the enhanced video or trust auto-QoS
configurations.
Explicit migration to enhanced auto-QoS occurs on a switch when you enable the
auto qos srnd4
global configuration command. You can configure the [
no
] form of this commandafter you remove
auto-QoS functionality from all switch interfaces.

When you disconnect the spanning tree protocol (STP) peer link, the STP port path cost
configuration changes.
There is no workaround.
