Interface Discard

Post the output to the following commands:

1.  sh interface Gi ;

2.  sh controller e Gi

Do not run the two commands on the port-channel interfaces.  I want to see the outputs of the physical interfaces of the port-channels.  Please do not post screenshots.

Re: Interface Discard

Thanks Leo

port 20,21 int one portchannel , port 22,23,24 in another portchannel , both portchannel has discard transmit packet , find the output below :
