Wireshark · Wireshark-users: [Wireshark-users] Capture filter with multiple VLANs

[Todd Adamson <tadamson@xxxxxxxxxxx>]

Is it possible to create a capture filter to deal with 
multiple vlans?  What I would like to do is:

not (vlan 20 or vlan 30)
or
not vlan 20 and not vlan 30

So far, from what I've read, only the first vlan element is 
used in the filter.

Ideas?

Thanks.

Todd
