DTP Messages
Error Message DOT1X-5-INVALID_INPUT: Dot1x Interface parameter is Invalid on
interface [char]
Explanation
The parameter that is specified for the 802.1X interface is not valid (it could be outside
the range of valid values).
Recommended Action Try again, using a valid value. See the CLI help to find the valid 802.1X
parameters.
Error Message DOT1X-5-INVALID_MAC: Invalid MAC address(drop, zero, broadcast or
multicast mac address) <mac address> is trying to authenticate."
Explanation
Authentication is allowed for an invalid source MAC address because it is nonzero, it is
not a broadcast, and it is not a multicast MAC address.
Recommended Action Connect an 802.1X-supported host to the 802.1X-enabled interface.
Error Message DOT1X-5-NOT_DOT1X_CAPABLE: Dot1x disabled on interface [char] because
it is not an Ethernet interface
Explanation
The user attempted to configure 802.1X on a non-supported interface. 802.1X can be
enabled on Ethernet module interfaces only.
Recommended Action Enable 802.1X authentication on Ethernet interfaces only.
Error Message DOT1X-5-SECURITY_VIOLATION: Security violation on interface [char] in
single-host mode. Authorized MAC address was [mac-addr]
Explanation
That the port is configured in Single Host mode, so that any new host that is added to
this interface results in a security violation and the port is shut down.
Recommended Action Ensure that the port is configured to use only one host. Enter the shutdown
command followed by the no shutdown command to restart the port.
