Important Notes
•
The duplex setting shown by the device manager for an Ethernet interface is not the same as the
duplex setting in the running configuration. This occurs when you change the only duplex setting
on the device manager from Auto to Full. The speed setting remains Auto. When the device manager
page is refreshed after the configuration change, the duplex setting is reported as Auto.
duplex setting in the running configuration. This occurs when you change the only duplex setting
on the device manager from Auto to Full. The speed setting remains Auto. When the device manager
page is refreshed after the configuration change, the duplex setting is reported as Auto.
The workaround is to configure the Ethernet interface at 10, 100, or 1000 Mbps, remove the full
duplex setting on the Ethernet interface and let the duplex return to Auto. If you had configured full
duplex because the Ethernet interface was autonegotiating to half duplex, configure the speed and
duplex settings on both link partners. (CSCeh58774)

•
When an IEEE 802.1x-authenticated client is disconnected from an IP phone, hub, or switch and
does not send an EAPOL-Logoff message, the switch interface does not change to the unauthorized
state. If this happens, it can take up to 60 minutes for the interface to change to the unauthorized
state when the re-authentication time is the default value (3600 seconds).

state when the re-authentication time is the default value (3600 seconds).
The workaround is to change the number of seconds between re-authentication attempts by using
the dot1x timeout re-authperiod seconds global configuration command. (CSCdz38483)

The guest VLAN might not assign a DHCP address to some clients. This is a problem with the
IEEE 802.1x client, not with the switch.

The workaround is to either release and renew the IP address or to change the default timers. These
examples show typical interface timer changes:
