sho ilmi stat or sho lane def will sho the nsap address if you have the well
known 0/16 ilmi pvc created. The arp server runs on a selected router. The
switch learns the configure esi addresses and sends the ip arp request to
the router that you define as the arp server. It does this using the fully
qualified nsap address which includes the esi address you define.
