20569-1 : BIG-IP Source IP cmp-hash setting is distributing traffic unequally
Component: TMOS
Symptoms:
After a period of time, Inet port exhaustion error messages begin to be reported, and traffic starts to fail:
crit tmm1[17985]: 01010201:2: Inet port exhaustion on <ip_address> to <ip_address>.
Conditions:
1. BIG-IP system uses sock or virtIO drivers; cmp-hash is src-ip.
2. Both VLANs are set to Source Address CMP Hash configuration.
3. Pool members are distributed to different TMM cores based on the VLAN configuration.
4. Traffic is load balanced to the pool member mapped to the other core.
Impact:
The system reports Inet port exhaustion error messages, and traffic starts to fail.

This is interesting, In SNAT statistics i am seeing its equally spreading traffic across all SNAT pool members.

In above article they are saying "The cmp-hash src-ip setting has been improved to avoid unequal distribution." so how do i configure cmp-hash src-ip setting ?
My current model F5 model is 10350 running 13.1.0.8 version of software and this guys having issue related SNAT.
If i am running same load-test on F5 model 10200 running 12.0.0.0 and i not seeing any issue. do you think it issue of 13.x.x.x ? That is why i want to revert my image to verify.
