How to monitor throughput on fc switch ports

Hi,

We recently started using the cisco nexus 5000 switch.

Previosuly we were using brocade switch.

In order to monitor the throughput on the switch ports, we used the command >perfportshow

output:

  0    1    2    3    4    5    6    7    8    9   10   11   12   13   14   15 Total

===============================================================================

52m   0    0   79m  79m  52m   0    0    0    0    0    0    0    0    0    0  262m

It used to depict the throughput on each of its 16 ports.

Do we have a similar command on a cisco nexus 5000 swithc to monitor the throughput dynamically on the ports.

Any guidance appreciated.

Thanks.

How to monitor throughput on fc switch ports

On 9509 switches I use " sh int counters brief module *" * for the number of each Module in this case 2 and I get the following output.

How to monitor throughput on fc switch ports

Thanks Roy.

But is that dynamic.. ?

What i mean is - in the portperfshow command, it systematically displays the throughput on the ports and that too in real time with a interval of 1 second.

You just fire the command and sit back and you will get per second throughput stats.

does the above has same capabilities?

Thanks.

How to monitor throughput on fc switch ports

I know that Brocade command from many years ago, no it doesn't do the automatic refresh. You can also use " sh int aggregate-counters brief" for all the modules usage but that doesn't refresh either. I think you could script something to re-run either command every 5 minutes thou.

How to monitor throughput on fc switch ports

Hi,

You can try Device Mangaer summary tab.
It's #3 in this link.http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/sw/5_2/configuration/guides/fund/DCNM-SAN-LAN_5_2/dm.html#wp254943

The poll interval might be 10 or 30 seconds. Select Util%.

Regards,

David
