The configuration examples in this chapter use the format for ERX-7xx models, ERX-14xx models, and the ERX-310 router to specify a SONET/SDH interface. (The format is described in Numbering Scheme .)
For example, the following command specifies a SONET/SDH interface on port 0 of an I/O module in slot 0.
- host1(config)#controller sonet 4/0
When you configure a SONET/SDH interface on an E120 router or an E320 router, you must include the adapter identifier as part of the interface specifier. For example, the following command specifies a SONET/SDH interface on port 0 of the IOA installed in the lower adapter bay (0) of slot 3.
- host1(config)#controller sonet 3/0/0
