Statement introduced before Junos OS Release 7.4.
For unchannelized OC3, OC12, and OC48 SONET/SDH interfaces on T Series routers only, configure the interface to interoperate with SONET/SDH line-terminating equipment (LTE) that is provisioned for unidirectional linear APS in 1+1 architecture.
If the switching-mode statement is not configured, the mode is bidirectional, and the interface does not interoperate with a unidirectional SONET/SDH LTE.
bidirectional—Support bidirectional mode only.
unidirectional—Interoperate with a SONET/SDH LTE provisioned for unidirectional mode.
