You
can specify a destination IP group of IP address that the firewall
will monitor. The firewall monitors the full path through the network
to mission-critical IP addresses using ICMP pings to verify reachability
of the IP address. The default interval for pings is 200ms. An IP
address is considered unreachable when 10 consecutive pings (the
default value) fail. You specify the failure condition for the IP addresses
in a destination IP group:
Any
IP address
unreachable or
All
IP addresses unreachable
in the group. You can specify multiple destination IP groups for
a path group for a virtual wire, VLAN, or virtual router; you specify the
failure condition of destination IP groups in a path group:
Any
or
All
,
which constitutes a path group failure. You can configure multiple
virtual wire path groups, VLAN path groups, and virtual router path
groups.
