MULTIPLE Rspan vlan one destination port

[ciscoenginner79]

Hi guys.

I tried to resolve the issue with my Rspan design. I have a multiple switches so I create a one Rspan vlan for one switch to limit the trafic on the up link. I am not able to create a monitor session with multiple RSapn and I tried to do multiple monitor session with each rspan vlan as source and destination this same interface no able. Worrying message appear.

Do You know some tricks that would work.

Bellow some entry with out success.

Monitor session 1 source remote vlan 511

Monitor session 1 destination inter gig 2/0/3

Monitor session 2 source remote vlan 512

Monitor session 2 destination inter gig 2 0/3

The worning pup up message appear that interface is use for another session.

I want to put all remote vlans to one interface. Any idea????

Thanks for help

Hi @ciscoenginner79,

SPAN sessions (local or remote) allow you to monitor traffic on one or more ports or one or more VLANs and send the monitored traffic to one or more destination ports. 

Note: One port can be a destination of a single SPAN session not multiple like you are trying. However, you can define multiple VLANs or Interface (separated by comma or hyphen) as the source. See below for your reference:

monitor session session_number source {interface interface-id | vlan vlan-id} [, | -] [both | rx | tx]
