E120 Router and E320 Router
Use the slot/adapter/port format to identify unchannelized SONET/SDH interfaces.
NOTE: The E120 router and the E320 router do not support path channelization.
■
slot —Number of the slot in which the line module resides in the chassis.
In the E120 router, line module slots are numbered 0–5. In the E320 router, line
module slots are numbered 0–5 and 11–16. For both routers, slots 6 and 7 are
reserved for SRP modules; slots 8–10 are reserved for switch fabric modules
(SFMs).
■
adapter— number of the bay in which the I/O adapter (IOA) resides.
This identifier applies to the E120 and E320 routers only. 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).
■
port —Number of the port on the IOA.
For information about installing line modules and IOAs in the E120 and E320 routers,
see
E120 and E320 Hardware Guide, Chapter 4, Installing Modules .
Interface Specifier
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” on page 81
.)
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
