Configure IDSM with RSPAN


We have here two 6509 switches with an IDSM blade in each one.

I want one of them to monitor a remote port on a remote switch.

But I can not see traffic on the IEV.

That is the configuration I used:

We have a pre configured RSPAN vlan (555) on our VTP servers.

1. on the remote switch:

monitor session 2 source interface Gi6/37

monitor session 2 destination remote vlan 555

2. on the 6509:

monitor session 2 source remote vlan 555

monitor session 2 destination intrusion-detection-module 2 data-port 2

3. on the IEV:

made a new filter with the scope of addresses used on that network.

made a new view using the filter I made.

If I forgot something tell me...

Thank You!!

Re: Configure IDSM with RSPAN

Not my area of expertise (RSPAN), but did you set up the IDSM2 ports to allow the proper vlans? This would be a switch config item, not an IPS config item.

Also, if you are running IPS 5 or 6, you can use the "packet" command to display what the IPS sensor is seeing on its sensing ports. Its a good way to see that your traffic is getting to the sensor.
