CSM session maintenance

[Rojer-bkk]

Hi,

I have two CSM (active/standby), if reset CSM active, current session on active will lost? I'm not sure about replicate csrp sticky and connection will help or not. Thank you for all feedback

Some configuration...

vserver CFI-8443
  virtual 10.108.50.123 tcp 8443
  serverfarm CFI-8443
  idle 600
  replicate csrp sticky
  replicate csrp connection
  persistent rebalance
  inservice

!

serverfarm CFI-8443
  nat server
  no nat client
  predictor hash address source
  real 10.108.50.124
   inservice
  real 10.108.50.125
   inservice
  probe CFI-TCP-8443

!

Hi Rojer,

the standby CSM will have the connections state and sticky entries replicated by the primary and will take over the active connections once the primary fails. There are certain requirements for this to work. You can find more details here:

hope this helps.
