# ICR Platform Considerations

ICR is supported on all E Series routers.

For information about modules supported on E120 and E320 routers:

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

For information about modules supported on ERX routers:

- See ERX Module Guide, Table 1, ERX Module Combinations for detailed module specifications.
- See ERX Module Guide, Appendix A, Module Protocol Support for information about the modules that support ICR.

## Interface Specifiers

The majority of the configuration task examples in this topic collection use the slot/adapter/port format to specify an interface. However, the interface specifier format that you use depends on the router that you are using.

For ERX7xx models, ERX14xx models, and ERX310 routers, use the slot/port format. For example, the following command specifies a Gigabit Ethernet interface on slot 0, port 1 of an ERX7xx model, ERX14xx model, or ERX310 router.

host1(config)#interface gigabitEthernet 0/1

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 a10-Gigabit Ethernet interface on slot 5, adapter 0, port 0 of an E320 router.

host1(config)#interface tenGigabitEthernet 5/0/0
