Spanning more than 1Gb data on 6513 1g port.

Hi Experts,

We have a server connected on 1Gig port with a traffic load of 900mb tx and 900mb rx. For business requirement we need to span rx and tx traffic to a destination of 1gig interface on same switch. Since total traffic is more than 1Gb, it is getting dropped in the switch. Is there any way we can monitor tx and rx seperately and give in to 2 different physical ports?

Thanks in advance..

Yes, when you setup the SPAN session, you can specify rx, tx, or both. Both is the default.

Example.

Monitor session 1 source int gi4/1 rx

monitor session 1 destination int gi4/2

monitor session 2 source int gi4/1 tx

monitor session 2 destination int gi4/3

Hope to Help.

I already tried this and got no luck. When you chose a port for a monitor session, you cannot choose the same port for other monitor session.

Is there any other way to do it?

Thanks for the reply..

Depending on the software release you are running you have an option to set a port-channel as a SPAN destination. If you do that you can bundle two or more Gig interfaces in a port-channel and send the SPAN traffic out of the port-channel. An obvious thing to consider is how you will process it, maybe your probe can take in multiple interfaces.

Hello

Thanks for the reply.

I have tried setting the destination interface as port-channel but no luck as the swithc is not taking the port-channel in output.

monitor session 2 source vlan 24
monitor session 2 destination interface Gi2/21

Switch(config)#monitor session 2 destination ?

This is not working

That is why I had written 'depending on the software release you are running' :-). You seem to be running 12.2(18)SXF17. This feature was introduced in 12.2(33)SXH I believe. If you want to upgrade then make sure you do a proper analysis of the new code specific to your operating environment.

OK Thanks Atif.

Let me test this and will update once i am through....

Thanks a lot.
