Hi,
I'm working on a config where the customer wants to both backup serverfarms on a CSM, which works and then within each farm, have a backup real.
The following config has been configured, however in serverfarm L1, both reals N01 and S01 are being used to balance connections, not just N01 as was expected. I have dug through the docs on CCO but it seems quite unclear to me. Any ideas, I have worked with server farms backing each other up within a vserver, but haven't seen this tried before.
!
serverfarm L1
nat server
nat client HIDE
real name S01
backup real name N01
inservice
real name N01
inservice standby
probe LDAP
!
serverfarm L2
nat server
nat client HIDE
real name S02
backup real name N02
inservice
real name N02
inservice
probe LDAP
!
vserver V1
virtual 1.1.1.1
serverfarm L1 backup L2
replicate csrp connection
no persistent rebalance
inservice
!
SW#sh mod csm 1 serverfarms name L1
nat = SERVER, CLIENT(HIDE)
virtuals inservice = 1, reals = 2, bind id = 0, fail action = none
inband health config: <none>
retcode map = <none>
Probes:
LDAP, type = script
Real servers:
N01, weight = 8, OPERATIONAL, conns = 27
S01, weight = 8, OPERATIONAL, conns = 26
Total connections = 47
!
Any help would be appreciated.
Regards,
Philip.

Hi Gilles,
Thanks, thats interesting, we use 4.2.4.
So the config is fine how it is and should only use the backup reals when the primary fails.
I suppose its likely a bug then.
