Surveillance Tasks for Alarms
Setting DS3 Alarm Thresholds
The chds3alm command changes the configuration settings for alarm severity, integration period, and
thresholds for various error conditions, such as LCV, LES, and LSES. The performance alarm is set if
the DS3 errors exceed any of the threshold counts set by this command. To change alarm threshold
values, enter the chds3alm command as described in the “chds3alm” section on page 9-56.
Monitoring Fast Ethernet Alarms
Fast Ethernet lines raise an alarm when an active line goes down, and invoke informational events for
line configuration changes.
To view the information for configured Fast Ethernet lines, enter the lsethlns command. The system
lists summary information for all Fast Ethernet lines:
