Monitoring switch health
The Nortel SNAS continually monitors the health of the network access
devices. At specified intervals, a health check daemon sends queries
and responses to the switch as a heartbeat mechanism. If no activity
(heartbeat) is detected, the daemon will retry the health check for a
specified number of times (the dead count). If there is still no heartbeat,
then after a further interval (the status-quo interval) the network access
devices moves all its clients into the Red VLAN. When connectivity is
re-established, the Nortel SNAS synchronizes sessions with the network
access devices.
The health check interval, dead count, and status-quo interval are
configurable.
To configure the interval and dead count parameters for the Nortel SNAS
health checks and status-quo mode, use the following command:
/cfg/domain #/switch #/hlthchk
The HealthCheck menu appears.
The HealthCheck menu includes the following options:
/cfg/domain #/switch #/hlthchk
followed by:
interval <interval> Sets the time interval between checks for
switch activity.
•
interval is an integer that indicates the
time interval in seconds ( s ), minutes ( m ), or
hours ( h ). The valid range is 60s (1m) to
64800s (18h). The default is 1m (1 minute).
