Cisco Cisco IOS Software Release 12.2(52)SE

Error Message DOT1X_SWITCH-5-ERR_SEC_VLAN_INVALID: Attempt to assign secondary VLAN 
[dec] to non-PVLAN host 802.1x port [chars] 

An attempt was made to assign a secondary VLAN to a port that is not a private VLAN 

host port, which is not allowed. [dec] is the VLAN, and [chars] is the port. 

Change the mode of the port so that it is configured as a private VLAN host 

port, or use a different VLAN that is not configured as a secondary VLAN. 

Error Message DOT1X_SWITCH-5-ERR_SPAN_DST_PORT: Attempt to assign VLAN [dec] to 
802.1x port [chars], which is configured as a SPAN destination 

An attempt was made to assign a VLAN to an IEEE 802.1x port that is configured as a 

Switched Port Analyzer (SPAN) destination port. [dec] is the VLAN, and [chars] is the port. 

Change the SPAN configuration so that the port is no longer a SPAN 

destination port, or change the configuration so that no VLAN is assigned. 

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] 

Multi-Domain Authentication (MDA) host mode cannot start if the configured 

data VLAN on a port is the same as the voice VLAN. [chars] is the port. 

Change either the voice VLAN or the access VLAN on the interface so that 

they are not the same. MDA then starts. 

Error Message DOT1X_SWITCH-5-ERR_VLAN_EQ_VVLAN: Data VLAN [dec] on port [chars] 
cannot be equivalent to the Voice VLAN. 

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. 

Change either the voice VLAN or the IEEE 802.1x-assigned VLAN on the 

interface so that they are not the same. 

Error Message DOT1X_SWITCH-5-ERR_VLAN_INTERNAL: Attempt to assign internal VLAN 
[dec] to 802.1x port [chars] 

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. 

Assign a different VLAN.
