CSM Sticky Cookie Insert

gtambour

Hello,

We have a Catalyst 6500 w/ CSM-S configuration that has 2 serverfarms with identical real servers using the same VIP. Each farm has 50 real servers (2 IPs with 25 consecutive ports each). One of the serverfarms is defined under a SLB policy with client NAT and the second one directly under the vserver. Both serverfarms are configured with the same sticky group for cookie insert. When I issue "show mod csm 13 sticky group 4" I only see 52 entries instead of 100. Also, some of the entries are duplicate. All the rest of the sticky groups are displaying the correct number of cookie entries, matching the number of real servers in the farms. Any ideas on why this is?

You probably have encountered the following bug fixed only in version 4.2.2

CSM: sticky insert table not updated if adding new reals

The workaround is to reboot the CSM or reconfigure reals, policy and vserver in the correct order.
