Julie Ann,

According to Novell docs (the latest) the IPX Type field decode:

 0x00 NLSP
 0x01 RIP
 0x02 Echo
 0x03 Error
 0x04 SAP
 0x05 SPX
 0x11 NCP (type 17)
 0x14 NetBIOS (type 20)

As far as cisco and what we do with type 17 - nothing. But of course we
can send/reply echo packets, we can send/receive NLSP packets, we can
send/receive RIP/SAP packets, we can spoof SPX, we can forward type-20
packets. Think that's what cco docs are trying to lead to.

Regards

Bernard.
