Default Trunk Policy Default Subscriber Policy Packet/Attribute Type
Permit Permit Relearn
Permit Permit Unicast (user-to-user)
Permit Deny Unknown unicast DA
Permit Permit Unknown protocol
Modifying Subscriber Policies
For a network interface configured as a subscriber (client) interface, you can modify
the default subscriber policy to change the default permit or deny value for one or
more of the packet or attribute types listed in Table 78 on page 590.
You cannot, however, change the default trunk policy for a network interface
configured as a trunk interface or for the VPLS virtual core interface. Trunk interfaces
and the VPLS virtual core interface always use the default trunk policy, which forwards
packets of all types and permits relearning.
Table 79 on page 591 lists the commands that you can use to modify subscriber
policies for subscriber (client) interfaces associated with either a VPLS instance or a
standard bridge group.

Considerations for VPLS Network Interfaces
When you configure network interfaces for a VPLS instance, you must ensure that
the subscriber policy in effect for the interface is appropriate for your network
configuration.
To ensure that the network interface permits relearning and forwards (permits)
packets for all of the protocol types listed in Table 78 on page 590, be sure to configure
the network interface as a trunk (server) interface so that it always uses the default
trunk policy. For example, the following commands associate a 10-Gigabit Ethernet
