Type of change
Back port request
Approach
What is the motivation for this PR?
Verification of the new feature of LAG ID allocation to PortChannel and new list of SYSTEM_LAG_IDS_FREE_LIST
How did you do it?
The test case verifies traffic flow between all port channels in a full mesh topology. It begins with a system reboot to allocate the lower series of LAG IDs and validate the SYSTEM_LAG_IDS_FREE_LIST. Next, the LAG IDs are incremented through temporary port channel additions and deletions. A configuration reload is then performed to allocate higher LAG IDs to the port channels, followed by a final validation of mesh traffic.
How did you verify/test it?
Verified on T2 VOQ Chassis
Any platform specific information?
Applicable for T2 Chassis
Supported testbed topology if it's a new test case?
T2 Chassis
