I assume that inter traffic group table access was somehow possible before 11.4 and now it's not. I can see benefits of session table space partitioning per TG but kind of read only access (lookup) could be implemented - as it seems to be fastest way to exchange data between iRules in different TGs - but well, we have what we have and have to figure out some way to use it :-)

 

Great explanation about difference between network connection and session table and how mirroring works for both! Thanks for help (again :-)

    One additional question. I am pretty sure that I saw somewhere (in some SOL) info that even if now HA and connection mirroring can be done between different types of devices (like 2000 <-> 4000) or VE with different config it is still required to have identical hardware in case of session table mirroring - are you aware about such limitation or it's no longer there?
