Switching

Hi,

I have a port mirror configured, which is mirroring traffic from a trunk port.
When I capture the traffic in Wireshark, there's no VLAN tags includes.

Is there something special I need to do to keep the VLAN tags in the capture?


Thanks

Hello Luke:

I am assuming that you have a local analyzer configured and this is why you cant see the VLAN tags on the capture. If you want to see traffic from specific VLANS a remote analyzer needs to be configured. You can find configuration examples on the following article: https://kb.juniper.net/InfoCenter/index?page=content&id=KB10878&cat=SWITCH_PRODUCTS&actp=LIST 

Kind regards
