Hello,
I've seen the ISIS/OSI dissector does not work at least since 10.6;
ethereal claims the packet has an "Unknown ISO protocol":

No.     Time        Source                Destination           Protocol Info
     58 19.737276   N/A                   N/A                   ISO   
  Unknown ISO protocol (21)

Frame 58 (313 bytes on wire, 313 bytes captured)

    CLNS Padding: 0x83

But 0x83 is the common protocol-id for ISIS in OSI; the decoding should be:

Frame 58 (313 bytes on wire, 313 bytes captured)
Cisco HDLC
    Address: Multicast (0x8f)
    Protocol: OSI (0xfefe)
    Intra Domain Routing Protocol Discriminator: ISIS (0x83)
    PDU Header Length  : 33
    Version (==1)      : 1
    System ID Length   : 0
    PDU Type           : L2 CSNP (R:000)
    Version2 (==1)     : 1
    Reserved (==0)     : 0
    Max.AREAs: (0==3)  : 0
...etc

I've upgraded to 10.10 without success

Does anybody knows if there's a bug or any?

Thank you
