arubaos / procurve switche - find out ip address of connected clients

option (1):
-----------------
one way to do that in a nice way is using "ip client-tracker"

command: ip client-tracker

# Enables or disables the visibility of statically and
# dynamically assigned IPv4 and IPv6 addresses for both
# authenticated clients and non-authenticated clients

to see the clients run the command: show port-access clients


option (2)
----------------
the other way is using dhcp snooping

commands:
DHCP-Snooping Configuration:

(MySwitch)<config># dhcp-snooping enable
(MySwitch)<config># dhcp-snooping vlan 1099
(MySwitch)<config># show dhcp-snooping

and define a trusted interface where the dhcp answers are allowed to come from, for example:
Interface trk1
dhcp-snooping trust
exit

to see the clients run the command: show dhcp-snooping binding
