Hello,
Has anyone experience this.. I have a Cisco 6513 with 4x1gb interfaces going to a Fortigate firewall. We have added all interfaces to channel-group 256.
However a "show etherchannel 256 detail" shows a etherchannel 256 and 256A?????
If I look at the interfaces in 256A, they show packets output, but not input. The interfaces in channel-group 256 show both input and output. Clearly something is amiss here. Why would it create a channel-group 256A?? and why would there be packets input and not output on this channel-group.. See the output of a "show etherchannel 256 detail" below:

Try shutting down the port channel SVI , this will shutdown all ports in the channel group Then do a no shut which will bring all back up at the same time. If you tried adding them 1 at a time a lot of times it won't come up correctly .
