Description of PR
Summary:This commit introduces logic to assign the 'Dpc' role based on specific conditions within the port alias and subtype.
Fixes # (issue)
Type of change
Back port request
Approach
The 'Dpc' role is now assigned when:
The subtype is defined and equals 'SmartSwitch'.
The integer value extracted from the intf variable (starting from the 8th character) is greater than or equal to 224.
What is the motivation for this PR?
How did you do it?
How did you verify/test it?
Deployed the minigraph and confirmed that the DPU role configuration is present for all backplane interfaces.
Any platform specific information?
HwSKU: Cisco-8102-28FH-DPU-O
Supported testbed topology if it's a new test case?
