Ah. And that is why we ask the questions.  I didn't think of moving farther down the stack for the capture filters.  Thanks to everyone who sent the idea.

How about a capture filter such as this?

"vlan and not (ether[14:2]&0x0fff = 20 or ether[14:2]&0x0fff = 30)"

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

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
