Switch port transmit packets

[clark white]

Dears ,

I want to know in my 6500, 4500, 3560 ,3700 switches from which port i am receiving heavy traffic, by which command i will come to know.

thanks

Check your interface for any "packet output drops".  This particular counter should NOT be incrementing.

There are so many commands to determine. 

If you want to see the link utilization in real-time, the command (for Catalyst 2K & 3K) is "sh controller utilization" and the values are expressed in percentage.

Hi John, 

I'm in Canberra (east side of Australia).  You went to the west-side of Australia.

hi,

try the show interface summary command.

i've used one of our 3560 as an example.

#sh int summ

 *: interface is up
 IHQ: pkts in input hold queue     IQD: pkts dropped from input queue
 OHQ: pkts in output hold queue    OQD: pkts dropped from output queue
 RXBS: rx rate (bits/sec)          RXPS: rx rate (pkts/sec)
 TXBS: tx rate (bits/sec)          TXPS: tx rate (pkts/sec)
 TRTL: throttle count

  Interface               IHQ   IQD  OHQ   OQD  RXBS RXPS  TXBS TXPS TRTL
