HASH Carp Persistence

Hi guys,

 

I've just configured HASH persistence using CARP Algorithm, as describe in this document:

 

http://support.f5.com/kb/en-us/solutions/public/11000/300/sol11362.html

 

I've defined a persistence profile with this options:

 

Hash Algorithm: CARP

 

iRule: Select the iRule you created which contains the persist hash command.

 

Timeout: 0 seconds

 

This is the iRule:

 

when CLIENT_ACCEPTED { persist carp [IP::client_addr] }

 

This Persistence Profile has been applied in a Virtual Server type "Performance Layer (L4)" port UDP.

 

I've noticed something strange, active connections has increased around 35-40%, is this normal?, using this algorithm active connections have to be higher?

 

Thanks for your help, Ron
