Description
Use the voice-config command to enable the DHCP server to send option 184 and
suboptions of 184 when it assigns addresses from the global 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 global
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.
By default, the DHCP server does not support option 184 and its suboptions.
Related command: dhcp server voice-config.
Example
# Enable the DHCP server to support option 184 and its suboptions in the view of global
address pool 123, setting IP address of NCP to 1.1.1.1, IP address of the alternate NCP
