command to visualize PPS?

[Mehdi Talei]

Hello,

Is there a command to visualize the actual PPS in a L3 switch?

Thanks

Hi,

Not sure exactly what you are looking for

If you type

show int | inc line protocol | packets/sec

You will see an output like this:-

Vlan1 is administratively down, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

Vlan888 is up, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

Vlan999 is up, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

FastEthernet1/0/1 is up, line protocol is up (connected)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 1000 bits/sec, 1 packets/sec

FastEthernet1/0/2 is up, line protocol is up (connected)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 1000 bits/sec, 1 packets/sec

FastEthernet1/0/3 is up, line protocol is up (connected)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

FastEthernet1/0/4 is down, line protocol is down (notconnect)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

FastEthernet1/0/5 is down, line protocol is down (notconnect)

  5 minute input rate 0 bits/sec, 0 packets/sec

Desk_3750#sh int | in line protocol | packets/sec

Vlan1 is administratively down, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

Vlan888 is up, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

Vlan999 is up, line protocol is down

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

FastEthernet1/0/1 is up, line protocol is up (connected)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 1000 bits/sec, 1 packets/sec

FastEthernet1/0/2 is up, line protocol is up (connected)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 1000 bits/sec, 1 packets/sec

What I am looking for is to find out the actual forwarding rate that the switch is doing! In my case, I have a 3750X-48P which is able to forward 101.2 mpps and I want to have a command which gives me the actual rate!

Not sure though if such a command exists! Just curious...

Thanks

You probably realise this already, but worth checking - the Cisco 101.2 Mpps figure will have been based on a specific packet size (i.e. small 64 Byte packets.) Your packets are likely to vary a bit more than that, so even if there is a command to view the total figure, then it's unlikely to tie up very well with what you have in mind.

Also, bear in mind Mpps is based on all the uplinks being poluated and in use. Have you got the two 10GbE uplinks installed too? If not, then you're not going to get near the Cisco figure. I presume the Cisco figure is based upon x48 GbE switchports + two 10GbE uplinks = 68 x 1.488095 Mpps
