# Multiclass MLPPP Platform Considerations

You can configure multiclass MLPPP on the following E Series Broadband Services Routers:

- E120 router
- E320 router

## Module Requirements

For information about modules that support multiclass MLPPP on the E120 and E320 Broadband Services Routers:

- See E120 and E320 Module Guide, Table 1, Module and IOAs for detailed module specifications.
- See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information about the modules that support multiclass MLPPP.

## Interface Specifiers

For E120 and E320 routers, use the slot/adapter/port format, which includes an identifier for the bay in which the I/O adapter (IOA) resides. In the software, adapter 0 identifies the right IOA bay (E120 router) and the upper IOA bay (E320 router); adapter 1 identifies the left IOA bay (E120 router) and the lower IOA bay (E320 router). For example, the following command specifies a gigabitEthernet interface on slot 3, adapter 0, port 0 of an E320 router.

host1(config)#interface gigabitEthernet 3/0/0
