Finding IP Addresses of Devices connected to a switch

[itisok4me]

I have a few HPE 1920-48G Switch JG927A and 1920S 48G -JL382A in the network. How can i find the ip address of devices connected on each port of these switches. Going through the forums suggested me a few commands including

 show lldp info remote-device
show cdp neighbors detail

I am unable to see the show command on the 1920-48G Switch JG927A  model. Enabling the _cmdline-mode on command does not help either. 

Any help on this would be appreciated.

Hello  itisok4me,

You may try:

display arp

In the command line. Note it will work if layer 3 traffic is sent to the devices like ping or the switches are default gateways for the devices.

Hope this helps!

Hello,

You have to enable LLDP globally  

Network > LLDP. and Click the Global Setup tab

You can refer pg.213 and 214 from below user guide:

Thank you. This works a treat on 1920 model. 

Is there a similar way to find the ip on devices connected on the 1920s.
