Only LACP ifgrp member ports attached to one switch come up
Applies to
- ONTAP 9
- LACP ifgrp
- Multiple switches supporting ifgrp member ports
Issue
- Lack of multi-chassis lagg config on the switch causes only a subset of ifgrp member ports to participate in the ifgrp
- All participating ports in the ifgrp are attached to one switch
- All ports attached to a different switch do not participate
- Compare SystemID of "lag id" (ifgrp global) and "laggport" (member port specific) sections of ifconfig
- Member ports with different SystemIDs than that in the "lag id" section are connected to switch ports which are not part of the same port channel configuration on the switch
- Example ifconfig -vvv output (Green: correct SystemID; Red: Incorrect SystemID):
-
lag id: [(8000,D2-39-EA-53-E0-03,082F,0000,0000), (8000,94-8E-D3-7F-DB-DD,0066,0000,0000)] laggport: e8b flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING> [(8000,D2-39-EA-53-E0-03,082F,8000,0007), (8000,94-8E-D3-7F-DB-DD,0066,8000,0009)] input/output LACPDUs: 50321 / 50293 laggport: e4b flags=18<COLLECTING,DISTRIBUTING> state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING> [(8000,D2-39-EA-53-E0-03,082F,8000,000B), (8000,94-8E-D3-05-B1-29,0066,8000,0009)] input/output LACPDUs: 50323 / 50293
