Backup Only Server

Unlike a Backup/Overflow server, a Backup Only server is used to only backup real servers, and not
provide an overflow capability. This enforces maximum session capacity while still providing
resiliency. In this configuration, if the primary server reaches its maximum session capacity, the
backup server does not take over sessions from the primary server. The backup server only comes
into play if the primary server fails.
Example Define Real Server 4 as a backup only server for Real Servers 1 and 2
>> # /cfg/slb/real 4
>> Real server 4# rip 200.200.200.5
>> Real server 4# ena
>> Real server 4# /cfg/slb/real 1
>> Real server 1# backup 4
>> Real server 1# /cfg/slb/real 2
>> Real server 2# backup 4
Example Assign a backup/overflow server to a real server group
Similarly, a backup/overflow server can be assigned to a real server group. If all real servers in a
real server group fail the backup comes online.
>> # /cfg/slb/group <real server group
number>
>> Real server group# backup r4
