Best I can think of is tools to manufacture layer 2 frames. Arp poison
tools are an excellent example - though perhaps not perfect because you are
not running IP - regardless, an arp-poison tool will kick out frames with
MAC headers you specify. Additionally, any raw-packet-write tool should
all
LLC has a test frame. But the devices might not be using LLC. If they are
on Token Ring they probably are though.

I believe Fluke has a meter which will assist in this too.

Johnny,
Thanks for the reply, but I should have been clearer. The network we are
testing is not running TCP/IP. It is strictly a test bed for testing
filters based on layer 2 connectivity only, (the "r

Johnny,
Thanks for the reply, but I should have been clearer. The network we are
testing is not running TCP/IP. It is strictly a test bed for testing
filters based on layer 2 connectivity only, (the "real" network is running
SNA with SR/TRB). So in this case ping does not apply.

You can still use ping for your testing. Ping verify's connectivity "up to"
and "including" layer three. If you have no layer two connectivity due to
an acl, you have no layer three (or higher), and no response to ping.
