STP? oui:00-00-0c, pid:01-0b

[mariko.hayashi]

Hi,

During sniffing my network, I encountered a lot of SNAP frames with oui:00-00-0c, pid:01-0b, destination address: 01-00-0c-cc-cc-cd. I could not find any document about how to decode this frame. Has anyone got any decent list for these multicast frames destined for 01000ccccccc/01000ccccccd??

Thanks,
