[comp.dcom.lans] Token Ring Analyzer?

Help...

I am looking for information on Token Ring Protocol Analyzers.
Specifically, I would like an analyzer which can be programmed to simulate
a station on the ring.

The analyzer should be capable of making a decision based on the content of
an inbound frame and respond appropriately.

For example:

  WHEN inframe == {802.5 MAC + 802.2 LLC + SNAP + ARP_REQUEST}

    SEND {802.5 MAC + 802.2 LLC + SNAP + ARP_REPLY} 

  where everything inside "{}" pairs is the appropriate bit sequences or
  wildcards .

I have looked at Date General's Sniffer and Novell's Excelan.  Neither
SEEMS to offer this feature.  The are both "windows" into the network
rather than true simulators.

Does anyone know of an analyzer which will meet my needs?  Please send mail
to me directly.

Thank you,

Mike Traynor
