Description
Use the dhcp server voice-config interface command to enable the DHCP server to
send option 184 and suboptions of 184 when it assigns addresses from the specified
interface address pool.
Use the undo dhcp server voice-config command to disable the DHCP server to
send option 184 and suboptions of 184 when it assigns addresses from the specified
interface address pool.
The DHCP server sends option 184 and suboptions of 184 only when thus required by
the DHCP client.
Configure the NCP-IP suboption before configuring other suboptions; otherwise, they
cannot take effect.
