Has anyone had experience passing remote mirrored traffic from XOS switches through Cisco Nexus switches? I need to monitor traffic from my Extreme switches with a virtual machine on Cisco UCS blades connected to Cisco Nexus switches. Is there a way to get Extreme Remore Mirror traffic into a Cisco RSPAN VLAN? (from Brad_Morgan)

Did you solve this problem? I have a similar request in my network.

If still problem is not resolved.
Could one of you guys open a TAC case with Extreme.
Extreme TAC can help on this.
I configured remote span between Extreme Networks X460-24p and Cisco Cataylst 2960X switches. 2 IP phones are connected to ports 15 and 17 on Extreme switch, and are monitored to port 1/0/47 on Cisco switch. Extreme and Cisco switches are interconnected with trunk (port 28 on Extreme with port 1/0/51 on Cisco).

I configured the following:

On Extreme switch:

configure mirror mode enhanced
enable mirroring to port 28 remote-tag 1000
configure mirroring add port 17 ingress-and-egress
configure mirroring add port 15 ingress-and-egress

On Cisco switch:

vlan 1000
name RemoteSPAN
remote-span
monitor session 1 destination interface Gi1/0/47
monitor session 1 source remote vlan 1000

This is working 🙂
