Monitoring Interfaces

To display statistics for channelized SONET and SDH interfaces, use the show controllers sonet command. The following section describes some of the options for the command and shows some sample displays.

From User Exec mode, use the following show commands to monitor and display the T3, T1/E1, and HDLC serial data channel information:

Setting a Baseline

You can set statistics baselines for serial interfaces, subinterfaces, and circuits using the baseline interface serial command. You can also set statistics baselines for the section, line, and path layers using the baseline interface sonet command. Use the delta options with the show commands to display statistics with the baseline subtracted.

Output Filtering

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See Command Line Interface in JunosE System Basics Configuration Guide, for details.
