Monitoring Interfaces
Use to display statistics for the different layers in channelized SONET and SDH
interfaces. Figure 8 on page 113 shows the layers in the interface.
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.
To view information for a specific controller in a layer, enter the specifier for the
controller and the type for the controller. For example, to view tributary 1/1/1
on path 1 of interface 4/0, enter show controllers sonet 4/0:1/1/1/1 tributary.
To view information for all controllers above a particular layer, enter the specifier
for the layer and the type for the controller. For example, to view all tributaries
on path 1 of interface 4/0, enter show controllers sonet 4/0:1 tributary.
To view statistics for a layer, specify the type of layer.
To view the configuration for a controller or all controllers in a layer, omit the
controller type.
To view all statistics for all sessions, specify the total keyword.
To view baselined statistics for all intervals, specify the delta total keywords.
Field descriptions
Current Interval Counters Statistics for the current 15-minute interval
Errored seconds Number of errored seconds encountered by a T1 or
an E1 in an interval
Severly errored seconds Number of severely errored seconds
encountered in an interval
Severly errored framing seconds Number of severely errored framing
seconds encountered in an interval
Coding violations Number of coding violations encountered in an
interval
Unavailable seconds Number of unavailable seconds encountered in
an interval
Last Interval Counters Statistics for the previous 15-minute interval
Current Far End Interval Counters Statistics for the remote connection
associated with the SONET/SDH path in the current 15-minute interval
Last Far End Interval Counters Statistics for the remote connection
associated with the SONET/SDH path in the previous 15-minute interval
Total interval counters Shows the statistics for all intervals or baselined
statistics
Example 1 This example shows the MIB statistics for the section layer on
interface 2/1.
