Configuring port channels on Netvana 1638's with qos trust cos.

When configuring port channels on Netvana 1638's with qos trust cos do you apply on the individual ports or on the port channel interface?

Re: Configuring port channels on Netvana 1638's with qos trust cos.

Hi roberts:

Thank you for posting your question in the Support Community!

The command is accepted on the ports and the port-channel interfaces.  I'm guessing that the port-channel interface is key for aggregate interfaces.  The switch ports see only LACP frames and I'm not sure whether any COS tags are present, so trusting COS would seem to be irrelevant.  I don't have a firm answer (nor do I see this question answered in the documents Link Aggregation Control Protocol (LACP) in AOS‌ or Configuring Ethernet Switch QoS and CoS in AOS‌).  I don't think there's any danger in using the command for both the ports and port-channel.  Perhaps someone will have a better answer.

Best,

Chris
