Aruba OS - which ip addresses from clients are connected to a switch?

2 methods are available (at least)

1) use dhcp snooping

turn on:
(SW)<config># dhcp-snooping enable
(SW)<config># dhcp-snooping vlan 99
(SW)<config># show dhcp-snooping
>> define trusted interface where the dhcp answers are coming from, for example interface 49 (your uplink)

see the clients: (Switch)<config># show dhcp-snooping binding


2) client tracker

turn on:
(SW)<config># ip client-tracker
(SW)<config># ip client-tracker probe-delay 300
see the clients: show port-access clients

!!! very important ->> use ip client-tracker always with a delay with at least 120 seconds, otherwise you could have problems with dhcp.
There are models like Aruba 2540, that are still (2025-11) not able to set the delay ... do not use client tracking if you have dhcp clients there !!!
