Parameters
ncp-ip ip-address: Specifies the IP address of the primary network calling processor.
as-ip ip-address: Specifies the IP address of the backup network calling processor.
voice-vlan vlan-id: Specifies the voice VLAN ID, in the range of 2 to 4094.
disable: Disables the specified VLAN, meaning DHCP clients will not take this VLAN as their voice
VLAN.
enable: Enables the specified VLAN, meaning DHCP clients will take this VLAN as their voice
VLAN.
fail-over ip-address dialer-string: Specifies the failover IP address and dialer string. The dialer-string is
a string of 0 to 39 characters, which can be 0 to 9, and "*".
Description
Use the voice-config command to configure Option 184 and its sub-options in the global address pool.
Use the undo voice-config command to remove Option 184 and its sub-options from the global
address pool.
The DHCP server answers Option 184 and the corresponding sub-options only after the DHCP client
requests Option 184.
By default, a DHCP server global address pool does not assign Option 184 and the corresponding
sub-options to the client.
Related commands: dhcp server voice-config.
