www.dell.com | support.dell.com 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).
