If using Ethernet – No Spanning Tree uplinks, use the CLI commands in this section to validate the configuration.
show port-channel summary on MX9116n FSE
From the MX I/O module, use the show port-channel summary
command to confirm the port-channel is created for the uplink with spanning-tree disabled on MX Switches

Upstream switch validation - SmartFabric OS10
show port-channel summary
From the upstream switch, run the show port-channel summary CLI command to verify port-channel is up and running and no STP BPDUs are received on the upstream switch. This command is for SmartFabric OS10. If the upstream swtich is not running OS10, execute the similar command specific to that switch model.
show spanning-tree interface port-channel
From the upstream switch, run the show spanning-tree interface port- channel
CLI command to verify that no BPDUs are received on the port.
show running-configuration interface port-channel
From the upstream switches, use the show running-configuration interface port-channel
CLI command to verify spanning tree is enabled on the port-channel interface. Then run the show lldp neighbors
command to show that no BPDU packets are received on the interface.
show lldp neighbors
After running the show running-configuration interface port-channel
command above, use the show lldp neighbors
CLI command to verify that no BPDU packets are received on the interface.
Upstream switch validation - Cisco
show port-channel summary
From an upstream Cisco Nexus switch, run the show port-channel summary CLI command to verify port-channel is up and running and no STP BPDUs are received on the upstream switch.
show running-configuration interface port-channel
Run the show running-config interface port-channel {port-channel ID}
command on the Cisco Nexus to show spanning tree configuration.
