Port Mirroring and Surf Control

Unanswered Question
Apr 16th, 2007

I have not been able to mirror firewall traffic to surf control since we changed switches to catalyst 4506. I have the following commands entered where Gi5/23 is the firewall interface and Gi5/12 is the SurfControl interface:

monitor session 1 source interface Gi5/23

monitor session 1 destination interface Gi5/12 ingress vlan 150 learning

sho monitor detail

Session 1

---------

Type : Local Session

Source Ports :

RX Only : None

TX Only : None

Both : Gi5/23

Source VLANs :

RX Only : None

TX Only : None

Both : None

Source RSPAN VLAN : None

Destination Ports : Gi5/12

Encapsulation : Native

Ingress : Enabled, default VLAN = 150

Learning : Enabled

Filter VLANs : None

Filter Addr Type :

RX Only : None

TX Only : None

Both : None

Filter Pkt Type :

RX Only : None

Dest RSPAN VLAN : None

IP Access-group : None

Any ideas on why it's not working?

Thanks,

Mary

I have this problem too.

Further on this .... The network card on the surf control server is receiving packets. It just isn't doing anything with them -- no send packets and nothing appearing in surf control.

Thanks,

We moved SurfControl off of the hub to a Cisco 3750. What we did different is we made the source VLAN 1 (data VLAN) and made the destination the port where the SurfControl server is connected to. Hopes this helps.

What finally did it for us was adding encapsulation parameter to the destination.

I'm still a little unclear about which VLAN I should be using -- do you create one specifically for that port or use one that's already in use. We've got 6 VLANs in use.

I used VLAN 150 because that's where the destination port is assigned already.

It is working now, so I'm not going to mess with it.

Thanks,

Mary
