Keepalive not working between GSS and CSM

[hussainmo]

Hello,

We are using a KAL-AP keepalive between GSS and CSM for our global application. One problem we are facing is that the KAL-AP messages (UDP 5002) for VIP status are sent from GSS in one data center to the CSM in another data center. However the response from the CSM takes more than 40 seconds and by that time the firewall in between has already removed the connection. We don't see the same latency issue when we use utitlities like ping, traceroute etc between these 2 devices.

The communication between all other GSSs and CSMs in different data centers is fine.

Regards,

murtaza

Check if you are using the real address of the CSM for KAL-AP .
