Hello experts,

I would like to ask how to build a filter so when I'm capturing traffic I just want to capture some specific packets that contain radius av-pairs (from cisco devices).

I would like to gather specifically:

Radius Protocol
    Code: Access-Accept (2)
    Packet identifier: 0xcb (203)
    Length: 450
    Authenticator: 788d2c00367b1f3cfe87c2ac3038bdf0
    [This is a response to a request in frame 11]
    [Time from request: 0.023681000 seconds]
    Attribute Value Pairs
        AVP: l=43  t=Vendor-Specific(26) v=Cisco(9)
            VSA: l=37 t=Cisco-AVPair(1): url-redirect-acl=DR_WebAuthRedirect

The url redirect. I tried with:

tshark -ni internal -V -R 'radius.Cisco_AVPair'

Thanks

Have you read the Wiki on capture filters, are you aware of the differences / limitation of these vs. display filters?
