This article helps list out the OIDs that can be used to build the aggregate objects, if PAgP is unavailable on device snmpwalk
Smarts - 10.1.x / 2.x
TCSA - 2.x
SMARTS uses the PAgP (Port Aggregate Protocol) to build aggregate objects (ports and interfaces).
When PAgP is not available, one can use the LACP (Link Aggregate Control Protocol)/LAG (Link Aggregate Group) to build aggregate objects.
For LACP/LAG to build aggregate objects, the following OIDs need to be populated:
dot3adAggMACAddress {".1.2.840.10006.300.43.1.1.1.1.2"}
dot3adAggPortAttachedAggID {".1.2.840.10006.300.43.1.2.1.1.13"}
dot3adAggPartnerSystemID {".1.2.840.10006.300.43.1.1.1.1.8"}
dot3adAggActorSystemID {".1.2.840.10006.300.43.1.1.1.1.4"}
dot3adAggPortPartnerOperPort {".1.2.840.10006.300.43.1.2.1.1.17"}
dot3adAggPortActorPort {".1.2.840.10006.300.43.1.2.1.1.14"}
dot3adAggPortActorSystemID {".1.2.840.10006.300.43.1.2.1.1.3"}
dot3adAggPortPartnerOperSystemID {".1.2.840.10006.300.43.1.2.1.1.9"}
Once the above OIDs are populated, SMARTS can use this information to build the aggregate objects.
