How to monitor throughput on fc switch ports

[santoshsm]

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.

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.

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.

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.

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

After the port type has been changed from Ethernet to FC, the FC port will not be enabled on the switch until FCOE feature is enabled:

N5K(config)#feature FCOE
C license checked out successfully
fc_plugin extracted successfully
FC plugin loaded successfully
FCoE manager enabled successfully
FC enabled on all modules successfully
Enabled FCoE QoS policies successfully
