Q:

VLAN mirroring supported switches and how to configure VLAN mirroring?



A:

VLAN mirroring are only supported on switch models like 2930M/F, 3810, 5400 series and above. Following switch models, 2530, 2540 and 2920 doesn't support VLAN mirroring. Below is how VLAN mirroring can be configured. This example is from a 2930F switch running WC.16.05.0004.

 

# mirror <mirroring profile 1-4> port <Destination port>
# mirror 2 port 1/4

# vlan 10
monitor all both mirror 2

# show monitor 2

Is there a way to mirror multiple VLANs to one session?

 

Like having VLANs 10,17,64,72, and 4000 in session 2

 

I tried the steps above and it seems like I'm just overwriting the previous VLAN.
