Field Description
Wait Time If disruption to the primary Cisco MGM server occurs, the Wait Time field
provides the number of seconds the client waits before attempting to log into the
backup server.
No. of Retries If the first backup Cisco MGM server is not available, this field provides the
number of times the client should retry logging in before moving to the next
server on the list.
Server List Lists the Cisco MGM servers that Cisco MGM clients will log into if access to
the primary Cisco MGM server is disrupted. The Add button adds a Cisco MGM
server to the Cisco MGM server list. The Remove button removes a Cisco MGM
server from the list.
If access to the primary Cisco MGM server is disrupted, the Cisco MGM client
tries to log back into the primary server by default. If the Cisco MGM client
cannot log back into the primary server, and if the server list contains server
names, the client tries to log into each backup server in the order listed until the
last server in the list is reached, or until the client successfully logs into a server.
