QOS+CobraNet

Evening,

Does CobraNet's ethernet frames tag DSCP or QOS? I haven't done a packet capture yet.

The wikipedia page for CobraNet specifies an ethertype of 0x8819. Should we build our policies off that?

Thanks!

    CobraNet packets do indeed have packet type 0x8819.
    Both Broadcast and Unicast packets are employed.

    The CobraNet.info site has this to say about QoS:

    Quality of service features impose a priority structure on data passing through a switch. Higher priority traffic is routed through the switch more quickly and is less likely to be discarded if bandwidth capabilities are exceeded. Traffic priority can be determined by a number of factors including port assignment, DTE address, protocol type and VLAN membership. QoS can be used to give the time sensitive CobraNet data precedence over less sensitive computer traffic, insuring that other transactions occurring over the network do not affect audio delivery.

    I read the cobranet.info site and it described QOS but not how cobranet handles it or participates in it... I guess it's packet capture time.. :)
