3300 ICP Technician's Handbook
Reprogram external DHCP servers (required for Release 7.0)
Note: If you intend to rely on LLDP VLAN Discovery in the network, you must
first upgrade the 3300 ICP to Release 7.0 or later and upgrade the IP Phone
firmware to version 2.0.0.18 or later.
Note: LLDP-MED non-compliant telephones cannot use LLDP for VLAN
discovery. They must use DHCP VLAN discovery. Non-compliant sets are:
5001, 5005, 5010, 5020 IP Phones, 5140 IP Appliance, 5201, 5205, 5207,
5215 (single mode), 5220 (single mode), 5230 IP Phones, 5240 IP Appliance,
5485 IP Pager, and 5550 IP Console keypad.
1. Use option pairs 60/43 or 124/125, whichever is most appropriate for
the customer's environment.
2. Ensure that previously programmed options 128-133 values are in
place for the global scope and any defined sub-scopes in the DHCP
server(s).
Note: DO NOT delete Options 128-133 yet.
3. Ensure that the TFTP server pointed to by option 128 corresponds to
a server (possibly an upgraded ICP) that contains the new IP Phone
software loads.
4. On the DHCP server(s), create a global scope corresponding to option
60 or option 124 (as selected above). Repeat for each sub-scope (if
any).
5. On DHCP server(s) define option 43 or option 125 (as selected above)
for each newly created scope. See the 3300 System Administration
Tool Help for information on formatting the required option strings.
Note: The values used in the option 43 string must correspond exactly to
previous option 128-133 values.
6. After the upgraded controllers are returned to service, and all IP
Phones have re-homed to them, use the LOAD IP 1-700 maintenance
command to force a firmware reload of all devices.
7. Delete old options 128-133 on all DCHP servers.
