Monitoring SONET/SDH Interfaces
Use to display statistics for the different layers in channelized SONET and SDH
interfaces. Figure 5 on page 78 and Figure 6 on page 79 show the layers in the
interfaces.
For definitions of the MIB statistics, see RFC 2558 Definitions of Managed
Objects for the SONET/SDH Interface Type (March 1999).
Specify an interface in slot/port format (ERX-14xx models, ERX-7xx models, and
the ERX-310 router) or slot/adapter/port format (E120 and E320 routers).
To view statistics for a layer, specify the type of layer.
To view all statistics for all sessions, specify the total keyword.
To view baselined statistics for all intervals, specify the delta total keywords.
