Configuring Peer Host Tracking Probes
Step 5 In the Priority field, enter a priority for the host you are tracking by the standby member of the high
availability group. Valid entries are integers from 1 to 255 with higher values indicating higher priorities.
Assign a priority value based on the relative importance of the gateway or host that the probes are
tracking. If the host goes down, the ACE appliance decrements the priority of the high availability group
on the standby member by the value in this Priority field.
Step 6 Do the following:
• Click Deploy Now to save your entries and to return to the Peer Track Host Probes table. The table
includes the added probe.
• Click Cancel to exit this procedure without saving your entries and to return to the Peer Track Host
Probes table.
• Click Next to save your entries and to configure another peer track host probe.
