how to setup rspan to monitor vlan

We are trying to setup monitoring through RSPAN. One server in particular is virtualized in vmware. To force traffic out a specific physical/virtual nic would eliminate redundancy, so I'm trying to setup RSPAN to monitor a vlan -- we can do vlan tagging through vmware. This is what I've come up with.

1. Create VLAN as an RSPAN VLAN

conf t

vlan 50

remote span

vlan 45 (for server traffic tagging)

end

2. Create an RSPAN Source Session

conf t

no monitor session 50

monitor session 50 source vlan (new_vlan_num)

monitor session 50 destination remote vlan 50

end

3. Create an RSPAN Destination Session

conf t

monitor session 50 source remote vlan 50

monitor session 50 destination interface gigabitethernet0/1

end

Does this look about right?

Hi Chris,

Looks good... Implement and lets see whether its successfull or getting issues...

Though redundant, but make sure that vlan is allowed on trunks between switches.

HTH,

Smitesh
