Description
This article describes how to identify the hbdev(heartbeat port) that is used for session sync and config sync in 6/7K Chassis.

Solution
Both 6K and 7K Chassis have multiple hbdev(heartbeat port) which are fixed and built-in.
Below is an example of hbdev in 7K chassis:
# show sys ha
# config system ha
    set group-id 19
    set group-name "7K"
    set mode a-p
    set hbdev "1-M1" 100 "1-M2" 100 "2-M1" 100 "2-M2" 100  < -----------
    set session-pickup enable
    set override enable
    set priority 200
end
Heartbeat packets will be send out on both M1 and M2 hbdev (heartbeat port);
Session-sync only utilized the (active/highest priority) hbdev and will fall back to 2nd highest priority hbdev, if the previous hbdev failed.

To identify which heartbeat port was use for the session-sync, kindly run the following command:
# diag sys ha dump-by group

[FIM01] (global) # diag sys ha dump-by group
<hatalk>             HA information.
