For trunk ports or access ports configured with IEEE 802.1Q tagging, inconsistent statistics might
appear in the show interfaces counters privileged EXEC command output. Valid IEEE 802.1Q
frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the
frames are not counted on the interface statistics. There is no workaround. (CSCec35100).
If the number of VLANs times the number of trunk ports exceeds the recommended limit of 13,000,
the switch can fail.
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
When you are prompted to accept the security certificate and you click No, you only see a blank
screen, and the device manager does not launch.
The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)
When the physical UID LED of the switch is on, it is blue. However, when the image of this LED
on the device manager Front Panel view is on, it is green.
There is no workaround (CSCsd98457).

The behavior of the no logging on global configuration command changed in Cisco IOS
Release 12.2(18)SE and later. You can only use the logging on and then the no logging console
global configuration commands to disable logging to the console. (CSCec71490)
In Cisco IOS Release 12.2(25)SEC, the implementation for multiple spanning tree (MST) changed
from the previous release. Multiple STP (MSTP) complies with the IEEE 802.1s standard. Previous
MSTP implementations were based on a draft of the IEEE 802.1s standard.
If the switch requests information from the Cisco Secure Access Control Server (ACS) and the
message exchange times out because the server does not respond, a message similar to this appears:
00:02:57: %RADIUS-4-RADIUS_DEAD: RADIUS server 172.20.246.206:1645,1646 is not
responding.
If this message appears, check that there is network connectivity between the switch and the ACS.
You should also check that the switch has been properly configured as an AAA client on the ACS.
