To configure the default service instance on a port, use the encapsulation default command in the Interface configuration mode. To delete the default service instance on a port, use the no form of this command.
This command has no keywords or arguments.
No matching criteria are defined.
This command was introduced.
If the default service instance is the only one configured on a port, the encapsulation default command matches all ingress frames on that port. If the default service instance is configured on a port that has other non-default service instances, the encapsulation default command matches frames that are unmatched by those non-default service instances (anything that does not meet the criteria of other services instances on the same physical interface falls into this service instance).
Only a single default service instance can be configured per interface. If you attempt to configure more than one default service instance per interface, the encapsulation default command is rejected.
Only one encapsulation command must be configured per service instance.
The following example shows how to configure a service instance on a port:
Router(config-if)# encapsulation default
