Debugging Aggregator Operation
This section describes common troubleshooting procedures to use for error conditions that may arise
during Aggregator operation.
All interfaces on the Aggregator are operationally down
Symptom: All Aggregator interfaces are down.
Resolution: Ensure that port channel 128 is up and that the Aggregator-facing port channel on the
top-of-rack switch is correctly configured.
Steps to Take:
1. Verify that uplink port-channel 128 i s up (show interfaces port-channel 128 brief command) and
display the status of member ports (show uplink-state-group 1 detail command).
FTOS#show interfaces port-channel 128 brief

2. Verify that the downstream port channel in the top-of-rack switch that connects to the Aggregator is
configured correctly.
