%SYS-4-P2_WARN: 1/Tag 0
The switch generates %SYS-4-P2_WARN: 1/Tag
0… messages.
This example shows the syslog output that you see when this error
occurs:
%SYS-4-P2_WARN: 1/Tag [dec] on packet from [ether] port [chars],
but port's native vlan is [dec]
This message indicates that an 802.1Q-tagged packet was received on a
nontrunk port. The VLAN that is derived from the packet tag is different from
the port native VLAN. In the error message:
-
The Tag [dec] is the VLAN identifier
from the packet.
-
The [ether] is the host MAC
address.
-
The port [chars] is the port
identifier.
-
The second [dec] is the native VLAN
number.
There is a possibility that the local port is incorrectly configured
as an access port instead of a trunk port. Alternately, the remote side can
have been configured as a trunk port instead of an access port.
Verify that the local port is not incorrectly configured as an access
port instead of a trunk port. Also, verify that the remote side is not
configured as a trunk port instead of an access port.
Then also it shows check the port connectivity
