74.2.2 DHCP Server
The following describes DHCP Server commands.
74.2.2.1 ip dhcp-server
This command enables the specified address of the DHCP relay server to be used on the
specified interface or on all Layer 3 interfaces. It also provides support for the device to act
as a DHCP server for Lync-enabled IP phones, by supporting DHCP Options 120 and 43.
DHCP Option 120 enables SIP clients to discover a domain name system (DNS) FQDN
(Fully-Qualified Domain Name) of a SIP server (SIP Server Discovery). For detailed
information on DHCP Option 120, see RFC 3361. DHCP Option 43 enables devices to
discover the Microsoft Lync Server Certificate Provisioning service. For detailed information
on how to configure DHCP Option 120 and DHCP Option 43, see
http://technet.microsoft.com/en-us/library/gg412828%28v=ocs.14%29.aspx.
Use the no form of this command to disable the address of the DHCP relay server on a
specific interface or on all Layer 3 interfaces.
Note: Not all the commands in this section have a no form. See the details in the
commands syntax below. The no form for the ip dhcp-server <ip address>
command is used to disable the DHCP relay server.
