HA Overview Set Up High Availability

Additional master

hold up time

This time interval is applied to

the same event as Monitor Fail

Hold Up Time (range 0-60000

ms, default 500 ms). The

additional time interval is

applied only to the active

device in active/passive mode

and to the active-primary

device in active/active mode.

This timer is recommended to

avoid a failover when both

devices experience the same

link/path monitor failure

simultaneously.
