ERSPAN source Nexus 7000

All,

I hope you can assist with the following

I am trying to configure erspan between two nexus 7K my question here is regarding the origin IP address on a nexus7K with multiple VDCs.

The example below is from cisco website

With a Nexus 7K with multi VDC (from example below) should we have loopback1 configured in the admin VDC or the VDC we are trying to mirror traffic from. (As the monitor origin ip address x.x.x.x global command can only be configured in the admin VDC)

http://www.cisco.com/c/en/us/support/docs/switches/nexus-7000-series-switches/113480-erspan-nexus-7k-00.html

switch_1(config)#monitor erspan origin ip-address 10.254.254.21 global



!--- Configure the IP address for loopback interface, which is used
!--- as source of the ERSPAN traffic.

switch_1(config)#interface loopback1
switch_1(config-if)#ip address 10.254.254.21/32
switch_1(config-if)#exit

Many Thanks,

Zee

All can I please add another question can we have an ERSPAN on a nexus 7K set up as a source in one VDC and set as a destination in another VDC on the same N7K.

Unfortunately I could find any documentation from Cisco Regarding Erspan on nexus 7K with multiple VDC

Any help is much appreciated
