Hi everybody

Which ios command we can use to see as the packets enter or leave a particular port on cisco ios switches or router?

Here is my setp up

sw--- etherchannel---routed ports Router

I want to see which interface in etherchannel selects to send ip packets. We could use wireshark but my computer is pretty slow so I am wondering is there any particular ios command will do the job.

thanks and have a great weekend.

When I tried to open the link that is what i got:

The file or application you are trying to access may require additional  entitlement or you are trying to access a file with an invalid name.  Additional entitlement levels are granted based on a users relationship  with Cisco on a per-application basis.
