Hi,
This is the scenario:
2 3560 switches both are populated with IP phones. There is a specific Voice VLAN. The monitoring port is on switch1
It looks like you can not configure SPAN and RSPAN on the same switch using the same destination port.
So I can moonitor voice traffic on switch1 using SPAN or on switch2 using RSPAN.
Is there no way I can monitor both switches here?
Anyone has experience with this?
Thanks,
Jan

Here the configuration for a switch which is connected to the network monitoring device.
!Define the RSPAN VLAN Let's say vlan 100
vlan 100
remote-span
! Monitor session 1 captures bidirectional traffic from source vlan's to RSPAN VLAN 100.
! let's say we want to monitor traffic for multiple vlan which span over multiple switches in this example our source vlans are vlan 2 to vlan 20.
monitor session 1 source vlan 2 - 20
monitor session 1 destination remote vlan 100
! Monitor session 2 captures bidirectional traffic from RSPAN VLAN 100 to interface conected to network monitoring device say fa4/29
monitor session 2 source remote vlan 100
monitor session 2 destination interface fa4/29
On other switches do the following configuration
!Define the RSPAN VLAN Let's say vlan 100
vlan 100
remote-span
! Monitor session 1 captures bidirectional traffic from source vlans to RSPAN VLAN 100
monitor session 1 source vlan 2 - 20
monitor session 1 destination remote vlan 100
hope this will help

Hi Jan,
May be I did not understood your question well but configuring RSAPN you can monitor both switch 1 and switch 2 on a destination port which can be on switch 1 or switch 2.
