Configuration Tasks
Use to select an interface on which you want to configure SONET or SDH.
Use the interface specifier in slot/port:path-channel format (ERX14xx models,
ERX7xx models, and the ERX310 Broadband Services Router ) or slot/adapter/port
format (E120 and E320 routers). The E120 and E320 routers do not support path
channelization, and therefore does not support the path-channel specifier.
Example 1 Selects a SONET interface on ERX14xx models, ERX7xx models,
or the ERX310 router
host1(config)#controller sonet 4/0
Example 2 Selects an SONET interface on the E320 router
host1(config)#controller sonet 3/0/0
There is no no version.
See controller sonet.

host1(config-controll)#description boston-sonet-interface
