Hi. Trying to make an aggregated port (two 1Gb links)
asr1001x <-----> juniper ex4200
Juniper side reports that there are no issues (no drops or errors). But cisco port-channel shows some crazy output.
asr1.core#sh int port-channel 1
Port-channel1 is up, line protocol is up

Both interfaces on port-channel 1 are showing some unknow protocol drops:
