Ethernet Oversubscription for Dynamic Interfaces

When you configure S-VLAN subinterfaces over Ethernet interfaces to support dynamic
PPPoE subinterfaces, you can take advantage of VLAN and S-VLAN oversubscription.
For more information on S-VLAN oversubscription, see "S-VLAN Oversubscription"
on page 188 .

Platform Considerations

You can configure dynamic interfaces on the following E Series Broadband Services
Routers:

Module Requirements

For information about the modules that support dynamic interfaces on ERX14xx
models, ERX7xx models, and the ERX310 router:

E320 routers:

Interface Specifiers

The configuration task examples in this chapter use the slot/port[.subinterface ] format
to specify the physical interface that you want to configure to support dynamic
interfaces. However, the interface specifier format that you use depends on the router
that you are using.
