Identify the location of
DHCP and which DHCP
server is assigned IP
address for the
corresponding subnet
(see Appendix A on page
215 for examples>.
2.
For an external
Microsoft DHCP (NT
server, etc.), make sure
that the option type is set
to LONG.
Note: For Windows
2000, refer to TSB
#58001604.
3.
For a Cisco Router
DHCP, make sure that
the option type is set to
hex, and padded with 0s

for VLAN 2).

internal DHCP, set the

1.
Check the IP address
on the phone display.
2.

the conflict.
