Is there a debug or show option that will display ipx frame types being received at the router ?

[admin_2]

The show IPX traffic command displays a large amount of "format errors".

I suspect there are a number of devices on the network that are set to "auto-negotiate" the frame type.

Is there a debug or show command that would display ipx frame received that are not 802.3 ?

There is indeed a way to do that.

You have to first configure on your ethernet interface,

4 sub-interfaces. Each of them with a different IPX encap and a different network number:

int et 0.1

ipx network 1 encap snap

int ethe 0.2

ipx netw 2 encap ...

Then you enbable "debug ipx packet" and you will see

all the IPX packets whatever the encapsulation is.
