Hope this is an easy answer:

Command:
tshark -i eth1 -f "port 67 or 68" -V


In the below code snippet, I am trying to determine the option 43, but tshark is only givng me a partial value for option 43

    Option: (t=43,l=128) Vendor-Specific Information
        Option: (43) Vendor-Specific Information
        Length: 128
        Value: 01063C6E756C6C3E020445535442030845434D3A45535442...

It there a switch that will allow me a more verbose to complete value return?

I know about the -x option, but that gives me the whole packet, I only need the parsed option 43?


Thanks,

Moe
