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
This section describes how you can troubleshoot the scenario in which all the interfaces are down.
Symptom: All Aggregator interfaces are down.
Resolution: Ensure the 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 is up (show interfaces port-channel 128 brief command) and
display the status of member ports (show uplink-state-group 1 detail command).
