Statistics Commands for Troubleshooting

You can configure bucket statistics through Cisco WAN Manager (CWM) for logical lines, ports, and

channels (connections). Statistics configuration in CWM requires the TFTP mechanism. You can also

enter commands on the CLI. Refer to the Cisco WAN Switching Command Reference for descriptions of

the following commands:

• Logical line statistics: cnflnstats, dsplnstatcnf, and dsplnstathist

• Port statistics: cnfportstats, clrportstats, dspportstats, dspportstatcnf, and dspportstathist

• Channel (connection) statistics: cnfchstats, clrchstats, dspchstats, dspchstatcnf, dspchstathist

Integrated and Statistical Line Alarms

Integrated alarms for the UXM-E consist of LOS, LOF, AIS, YEL, LOC, LOP, Path AIS, Path YEL,

Path Trace, and Section alarms. The display for the dsplns command lists an alarm if the related event

occurs. You can configure the event duration that qualifies and clears an alarm with cnflnparm.

You can configure the class, rate, and duration for setting and clearing of statistical alarms with the

cnflnalm command. Refer to the description of cnflnalm in the Cisco WAN Switching Command

Reference publication for a list of all possible line alarm types. The display for the dsplnerrs command

shows data for existing alarms. To clear the statistical alarms on a line, use the clrlnalm command.

Loopback and Test Commands

The UXM-E supports local and remote loopbacks. You can establish a local loopback on either a

connection or a port. Remote loopbacks are available for connections only. No line loopbacks are

available for the UXM-E.
