24.3.2.9 Ping Trigger Configuration Example
Syntax trigger ping
Context Alarm Configuration context
Usage Create a ping trigger, and enter the Alarm Trigger Configuration context
for this trigger. The ping trigger monitors the network connectivity (i.e.,
network reachability) to a given host, using the ping command.
Associated with the ping trigger are the following settings:
❼ peer: The host to test the connectivity against.
❼ interval: the ping interval can be configured (see
section 24.3.8 )
❼ number: a robustness threshold, i.e., number of failed (or successful,
depending on the condition) pings required to consider the remote host
to be unreachable (or reachable), see
section 24.3.9 )
❼ outbound: to force ping to use a specific interface. Useful with dynamic
VRRP priority (see section 30.1.1 ), where you do not want to rely on the
system default gateway.
In this example a ping trigger is created and mapped to the default ac-
tion profile, to indicate alarm when the peer become unreachable after 3
retries.
