Juniper JUNOSE 10.0.X PHYSICAL LAYER, Configuration Manual

Page: 128 / 262

■
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.
