DOT1X Messages
Error Message
DOT1X-5-ERR_VLAN_RSPAN_CONFIGURED: VLAN [dec] is configured as a
Remote SPAN VLAN, which has Dot1x enabled interface(s) configured. Please disable
Dot1x on all ports in this VLAN or do not enable RSPAN on this VLAN.
Explanation
This message means that remote SPAN should not be enabled on a VLAN in which ports
are configured with 802.1x enabled. [dec] is the VLAN ID.
Recommended Action
Either disable the remote SPAN configuration on the VLAN, or disable 802.1x
on all the ports in this VLAN.
Error Message
DOT1X-5-INVALID_INPUT: Dot1x Interface parameter is Invalid on
interface [chars].
Explanation
The IEEE 802.1x interface parameter is out of the specified range or is invalid. [chars]
is the interface.
Recommended Action
Refer to the CLI help documentation to determine the valid IEEE 802.1x
parameters.
Error Message
DOT1X-5-INVALID_MAC: Invalid MAC address (zero, broadcast or multicast
mac address [chars] is trying to authenticate).
Explanation
This message means that authentication was attempted for a zero, broadcast, or
multicast MAC address using 802.1x. 802.1x authentication is allowed only for a valid nonzero,
nonbroadcast, or nonmulticast source MAC address.
Recommended Action
Connect a 802.1x-supported host to the 802.1x-enabled port.
Error Message
DDOT1X-5-NOT_DOT1X_CAPABLE: Dot1x disabled on interface [chars]
because it is not an Ethernet interface.
Explanation
This message means that you can enable 802.1x authentication only on Ethernet
interfaces. [chars] is the interface.
Recommended Action
Enable 802.1x authentication only on Ethernet interfaces.
Error Message
DOT1X-5-SECURITY_VIOLATION: Security violation on the interface
[chars], new MAC address [enet] is seen.
Explanation
A host on the specified interface is trying to access the network or to authenticate in a
host mode that does not support the number of hosts attached to the interface. This is a security
violation, and the port is put in the error-disabled state.
Recommended Action
Ensure that the interface is configured to support the number of attached hosts.
Enter the
shutdown
interface configuration command and then the
no shutdown
interface
configuration command to restart the port.
