TCP payload persistence (convert Cisco ACE l4-payload stickiness)
Hi all,
I'm currently transforming lots of Cisco ACE configurations to Big IPs running 11.6.0. On the ACE, there is a sticky method called "l4-payload" which can use a fixed offset and length setting in order to grab a specific portion of the TCP payload and generate a sticky entry based on that string (see http://www.cisco.com/c/en/us/td/docs/interfaces_modules/services_modules/ace/vA5_1_0/command/reference/ACE_cr/sticky.htmlwp1040212)
For example, I have the following sticky setting on the ACE that I need to convert to bigIP:
sticky layer4-payload my_l4_stickiness
layer4-payload offset 30 length 20
serverfarm my_serverfarm
timeout 1
replicate sticky
Which approach would you suggest? I think, I will need a combined iRule and universal persistence in order to achieve the same on the BigIP. Has anybody built something like that already? Any help is appreciated.
Thanks in advance!
Regards
Martin
