rspan not working properly .. i only see tx traffic

[manjeetsmahi]

I have 2 Cat swtiches both configured with vlan 2959 and vlan 3409 and i have trunk configurated between this two switches. Vlan 2959 is my source vlan and 3409 is my destination. On cat2 s/w i can all the traffic from remote s/w and local switch but on cat1 i can only see tx traffic from cat2.

monitor session 2 source vlan 2959
monitor session 2 destination remote vlan 3409

I have 2 port on CAT1 and CAT2 trunked to each other. I have switch mode trunk on all of them.

Any Clue ?

For RSPAN..

1. You ned to create a rspan vlan. In your case it seems to be vlan 3409.

These configs are required on both switches:

conf t

vlan 3409

remote-span

then

you put the following on the Switch with the source vlan.

monitor session 2 source vlan 2959
monitor session 2 destination remote vlan 3409

on the other switch where the destination port is... you put

monitor session 2 source vlan 3409
monitor session 2 destination

If this dont help send a topology and besides this, there are SPAN limitations per hardware. So what hardware are you using?
