Remote span only shows broadcast traffic

Hello,

 

I want to configure remote span, so that I can span the traffic on an access port of a WS-C2960X-24PD-L, to a sniffer that is on a WS-C2960G-24TC-L. The first switch has universal license the second lanbase.

I have configured a vlan for remote-span on my core switch and have permitted the vlan on uplinks towards the two switches. Unfortunately the only traffic that is spanned is broadcast traffic.

 

Here is the configuration:

WS-C2960X-24PD-L

monitor session 1 source interface Gi1/0/6
monitor session 1 destination remote vlan 999

 

sh vlan remote-span

Remote SPAN VLANs
------------------------------------------------------------------------------
997,999

 

WS-C2960G-24TC-L

monitor session 1 destination interface Gi0/12
monitor session 1 source remote vlan 999

 

sh vlan remote-span

Remote SPAN VLANs
------------------------------------------------------------------------------
997,999

 

Any ideas would be really helpful.

 

Thanks in advance,

Katerina

Hello

Have you allowed the span vlan over the trunks and on the other side of the span session where your analyzer resides have you directed the span traffic to that interface?

 

monitor session 1 source remote vlan 999
monitor session 1 destination interface x/x/x

Hello,
The vlans are allowed on trunks on all the path.

Thanks
