Server Maintenance Procedures

Source Server Failure Scenarios
In the event that the source R3000 unit should fail, the target
servers will continue to run using the last known configura-
tion loaded from the source server. However, all dynamic
authentication-based profiles will eventually time-out, since
the source R3000 server can no longer verify user creden-
tials. When this occurs, the information on the server can no
longer be trusted. In most cases, the failure of the source
server can be quickly repaired, though it is possible the
source server will be down for an extended period of time
due to detailed troubleshooting that needs to be performed,
or that the source server will need to be replaced due to
hardware failure.
In cases in which the source R3000 server is out of commis-
sion for an extended period of time, this server should be
replaced as soon as possible so that individual user authen-
tication can be executed, and the ability to control the
filtering cluster is continually enabled. In cases in which the
R3000 will not be immediately replaced, one of the target
R3000 servers should be designated as the new source
server.

Establish Backup Procedures

To prevent down time during a source server failure, 8e6
recommends establishing backup and restore procedures.
It is important that regular backups of the source R3000
server are saved using the Backup/Restore window in the
System section of the R3000 console. Once a backup is
created, it can be downloaded to another machine for safe-
keeping. A backup should be created and downloaded
whenever a change is made to filtering settings on the
source R3000 server.
