After failover from A to B,the traffic is not flowing to B

Even after the failover from A to B is fine, the traffic doesn't flow through B, I have checked for both traffic groups where masquerade is enabled and other is not, same behaviour

its a vcmp guest running on a vipriion 2200/2400 platform- we have masquerdaes MAC and non Masqurade MACs as well, both caused issues

FYI, physical interaces was OK,

also i noticed, STATS were present on the VIPS at B side, but apps werent accessbile, so i suspect something was going to A side as well?

    Ah, good to know ;) Sounds like it is a bit more complex environment than initially thought. I'd recommend raising a support ticket and go through a structured troubleshooting process to get to the bottom of it.
