Configuration of DHCP options in a Cisco device running the Cisco IOS DHCP
Server
The Cisco IOS DHCP server only allows Option 43 definitions for one device type for
each DHCP address pool, so only one device type can be supported for each DHCP
address pool. Complete these steps in order to configure DHCP Option 43 for VoWiFi
handsets:
1 Enter the configuration mode at the Cisco IOS command line interface (CLI).
2 Create the DHCP pool, which includes the necessary parameters, such as the
default router and the server name. This is an example DHCP scope:
ip dhcp pool <pool name>
network <ip network> <netmask>
default-router <default-router IP address>
dns-server <dns server IP address>
3 Add the Option 60 line with the following syntax:
option 60 ascii "VCI string of the handset"
NOTE: Avoid raw DHCP Option 43 without the specification of a VCI. Raw
DHCP Option 43 limits the DHCP server to support a single device type for
vendor specific information for each DHCP scope. Also, every DHCP client
receives the Option 43 values in a DHCP Offer, regardless of whether the values
are relevant to the device.
