[c-nsp] ingress vs egress queues

Hey guys,

 

Can someone please explain to me the difference between ingress and egress
queues on catalyst switches?

 

I always thought Ingress was traffic coming 'in' to the switch port from a
device and egress traffic coming out of the port but I don't think this is
correct?

 

Does a packet first go through the ingress queue and then to the egress
queue before it is 'switched'.

 

I have been trying to find some good documentation to aid my understanding
in this area. If anyone could help me out with this it would be greatly
appreciated.

 

Thanks,

 

-Aaron.
