DOT1X_SWITCH Messages
Error Message DOT1X_SWITCH-5-ERR_VLAN_EQ_MDA_INACTIVE: Multi-Domain Authentication
cannot activate because Data and Voice VLANs are the same on port [chars]
Explanation Multi-Domain Authentication host mode cannot start if the configured data VLAN on a
port is the same as the voice VLAN. [chars] is the port.
Recommended Action Change either the voice VLAN or the access VLAN on the interface so that
they are not equal. This causes Multi-Domain authentication to start.
Error Message DOT1X_SWITCH-5-ERR_VLAN_EQ_VVLAN: Data VLAN [dec] on port [chars]
cannot be equivalent to the Voice VLAN.
Explanation An attempt was made to assign a data VLAN to an IEEE 802.1x port that is the same as
the voice VLAN. [dec] is the VLAN, and [chars] is the port.
Recommended Action Change either the voice VLAN or the access/IEEE 802.1x-assigned V LAN on
the interface so that they are not equal. This causes the authentication to proceed normally on the
next retry.
Error Message DOT1X_SWITCH-5-ERR_VLAN_INTERNAL: Attempt to assign internal VLAN
[dec] to 802.1x port [chars]
Explanation An attempt was made to assign an invalid VLAN to an IEEE 802.1x port. The VLAN
specified is used internally and cannot be assigned to this port. [dec] is the VLAN, and [chars] is the
port.
Recommended Action Update the configuration to not use this VLAN.
Error Message DOT1X_SWITCH-5-ERR_VLAN_INVALID: Attempt to assign invalid VLAN [dec]
to 802.1x port [chars]
Explanation An attempt was made to assign an invalid VLAN to an IEEE 802.1x port. The VLAN
specified is out of range and cannot be assigned to this port.[dec] is the VLAN, and [chars] is the
port.
Recommended Action Update the configuration to use a valid VLAN.
Error Message DOT1X_SWITCH-5-ERR_VLAN_NOT_FOUND: Attempt to assign non-existent or
shutdown VLAN [dec] to 802.1x port [chars]
Explanation An attempt was made to assign a VLAN to an IEEE 802.1x port, but the VLAN was not
found in the VTP database. [dec] is the VLAN, and [chars] is the port.
Recommended Action Make sure that the VLAN exists and is not shut down, or use another VLAN.
