Command History
Usage Guidelines Enter the switchport autostate exclude command on a Layer 2 access or trunk port belonging to an SVI.
A VLAN interface (SVI) is up if ports are forwarding traffic in the associated VLAN. When all ports on
a VLAN are down or blocking, the SVI is down. For the SVI to be up, at least one port in the VLAN
must be up and forwarding. You can use the switchport autostate exclude command to exclude a port
from the SVI interface line-state up-or-down calculation. For example, you might exclude a monitoring
port from the calculations so that the VLAN is not considered up when only the monitoring port is active.
When you enter the switchport autostate exclude command on a port, the command applies to all
VLANs that are enabled on the port.
You can verify the autostate mode of an interface by entering the show interface interface-id
switchport privileged EXEC command. If the mode has not been set, the autostate mode does not
appear.
Examples This example shows how to configure autostate exclude on an interface and to verify the configuration:
Switch(config)#interface gigabitethernet 1/0/1
Switch(config-if)#switchport autostate exclude
Switch(config-if)#end
Switch#show interface gigabitethernet1/0/1 switchport
Name: Gi1/0/1
Switchport: Enabled
Administrative Mode: dynamic auto
