DOT1X (802.1X) Messages
Error Message DOT1X-5-ERR_PVLAN_TRUNK:Dot1x can not be enabled on private VLAN trunk
ports.
Explanation
802.1X cannot coexist with private VLAN trunking on the same port.
Recommended Action This is an informational message only. No action is required.
Error Message DOT1X-5-ERR_RADIUSVLAN_EQ_VVLAN: RADIUS attempted to assign a VLAN to
Dot1x port [char] whose Voice VLAN is same as Access Vlan
Explanation
The RADIUS server attempted to assign a VLAN to a supplicant on an interface whose
voice VLAN settings are identical to the access VLAN settings.
Recommended Action Update the RADIUS configuration so that the access VLAN settings are not
identical to the voice VLAN settings for this interface.
Error Message DOT1X-5-ERR_RSPAN_VLAN:Dot1x can not be enabled on ports configured in
Remote SPAN vlan.
Explanation
802.1X cannot be enabled on the remote SPAN VLAN port. This condition is caused by
trying to set 802.1X port control to auto or force-unauthorized (force_unauth) mode on a port that
is in the remote SPAN VLAN, which is not allowed.
Recommended Action Disable remove span on the VLAN, and then enable 802.1X.
Error Message DOT1X-5-ERR_SPANDST: Dot1x can not be enabled on [char]. It is
configured as a SPAN Dest port.
Explanation
The switch was not able to configure Dot1x on a given port because Dot1x and SPAN
destination ports are mutually exclusive features.
Recommended Action Disable the SPAN destination port configuration the reconfigure Dot1x on the
port.
Error Message DOT1X-5-ERR_TRUNK: Dot1x can not be enabled on Trunk port
Explanation
Because this port is a trunk port dot1x port-control cannot enter enable state with auto
mode (or disable state with force-authorized mode).
Recommended Action Disable trunking on the interface, and then enable 802.1X.
Error Message DOT1X-5-ERR_TUNNEL:Dot1x can not be enabled on 802.1q tunnelling
enabled ports
Explanation
802.1X cannot be enabled on the dot1q tunneling-enabled port. This condition is caused
by trying to set 802.1X port control to auto or force-unauthorized (force_unauth) mode on a
802.1Q tunnel-enabled port, which is not allowed.
Recommended Action Disable 802.1Q tunneling on the interface, and then enable 802.1X.
