Hello,

This is more of a curiosity rather than an actual technical question.

How *should* the command 'show ip arp' function?

I've noticed that on almost all network operating systems the 'show ip arp' 
command (or it's equivalent) shows the device (router/switch/whatever) in the 
table.

On NX-OS and Dell 10 Enterprise it only shows the hosts connected to the 
interface (and not switch/routers own IP)

I am mostly just curious as to "what is correct" also if anyone is aware of a 
command in NX-OS or Dell 10 E that shows it 'the old way' please enlighten me!

I would expect it to show the table of IP addresses and MAC addresses that it has learned via the ARP protocol. Static ARP entries (using configured and BIA MAC addresses) I wouldn't expect to see, unless labelled as "static" as opposed to "dynamic".
