Hi,
Just heard that, two ways to check the router interface:

1. I just know one way is to use the "show ip cache flow"

2. Anybody knows the other command ?

Cheers

I do not think this command :
---------------------------------------------------------------
#sh ip int brief
Interface IP-Address OK? Method
Status Protocol
GigabitEthernet0/0 192.168.1.251 YES NVRAM
up up
GigabitEthernet0/1 10.10.1.251 YES NVRAM
up up
Serial0/0/0:0 unassigned YES unset
down down
Serial0/0/0:1 unassigned YES unset
down down
---------------------------------------------------------------

As above, it can not display the line traffic nor which ip address
occupies the line

guys, Any other commands ?

THX

Then you are not looking for a router interface command. You are
looking for detailed information about traffic flows, which can only
be provided by netflow (which exports the ip cache-flow data to a
collector for analysis and reporting). Only other commands that can
give you a bit of visibility (but nowhere near as good as netflow) is
installing access lists and logging hits or debugging.
