Opened: May 09, 2016

Severity: 3-Major

Symptoms

Variables in the flow context when stored in the sessionDB cannot be shared since the traffic groups of the server and client flows are different.

Impact

Variable sharing in the TCL context will not work.

Conditions

DHCP virtual created in a non-local traffic group.

Workaround

Modify SysDb variable "Tmm.SessionDB.match_ha_unit" to disable the use of traffic-group ID while accessing the sessionDB.

Fix Information

Copy the traffic group from client to server connFlows such that both connFlows have the same traffic group.
