RSPAN traffic in Linux

Unanswered Question

I am having difficulties with getting RSPAN traffic in Linux over my trunk link.

Here's the setup .

[PC1]---[Gi0/1--CoreSw--Gi0/2]---802.1q trunk---[PC2_Linux]

CoreSW - Cisco C3560E version IOS 12.2(35r)SE

PC2_Linux - Linux PC with a VLAN is working properly

Current configuration of Gi0/1:

interface GigabitEthernet0/1

description MVTS1 port 1

switchport access vlan 21

switchport mode access


Current configuration of Gi0/2:

interface GigabitEthernet0/2

description Link to XEN01/1

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 60,66,98,208

switchport mode trunk

channel-protocol lacp

channel-group 1 mode passive


Current configuration of VLAN 98:

vlan 98



Current configuration of monitor sessions:

monitor session 2 source interface Gi0/1

monitor session 2 destination remote vlan 98

I'm trying to view a traffic from Gi0/1 on PC2. I don`t see it.

Can who help me and tell where the error?

A Catalyst 2950 switch may not RSPAN traffic correctly. This is due to an ASIC limitation specific to the 2950 platform.
