Configuring Option 184 parameters for the client To assign calling parameters to DHCP clients with voice service, you must configure Option 184 on the DHCP server. For more information about Option 184, see "Option 184." To configure option 184 parameters in a DHCP address pool: Step 1. Enter system view. 2. Enter DHCP address pool view. Command system-view dhcp server ip-pool pool-name 3. Specify the IP address of the primary network calling processor. voice-config ncp-ip ip-address 4. (Optional.) Specify the IP address for the backup server. voice-config as-ip ip-address 5. (Optional.) Configure the voice VLAN. voice-config voice-vlan vlan-id { disable | enable } 6. (Optional.) Specify the failover IP voice-config fail-over ip-address address and dialer string. dialer-string Remarks N/A N/A By default, no primary network calling processor is specified. After you configure this command, the other Option 184 parameters take effect. By default, no backup network calling processor is specified. By default, no voice VLAN is configured. By default, no failover IP address or dialer string is specified. Configuring self-defined DHCP options IMPORTANT: Use caution when configuring self-defined DHCP options because the configuration might affect DHCP operation. You can self-define options for the following purposes: • Add newly released options. • Add options for which the vendor defines the contents, for example, Option 43. • Add options for which the CLI does not provide a dedicated configuration command. For example, you can use the option 4 ip-address 1.1.1.1 command to define the time server address 1.1.1.1 for DHCP clients. • Add all option values if the actual requirement exceeds the limit for a dedicated option configuration command. For example, the dns-list command can specify up to eight DNS servers. To specify more than eight DNS servers, you must use the option 6 command to define all DNS servers. To configure a self-defined DHCP option in a DHCP address pool: Step 1. Enter system view. Command system-view Remarks N/A 39

Configuring Option 184 parameters for the client
To assign calling parameters to DHCP clients with voice service, you must configure Option 184 on the
DHCP server. For more information about Option 184, see "
Option 184
."
To configure option 184 parameters in a DHCP address pool:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter DHCP address pool view.
dhcp server ip-pool
pool-name
N/A
3.
Specify the IP address of the
primary network calling processor.
voice-config ncp-ip
ip-address
By default, no primary
network calling processor is
specified.
After you configure this
command, the other Option
184 parameters take effect.
4.
(Optional.) Specify the IP address
for the backup server.
voice-config as-ip
ip-address
By default, no backup
network calling processor is
specified.
5.
(Optional.) Configure the voice
VLAN.
voice-config voice-vlan
vlan-id
{
disable
|
enable
}
By default, no voice VLAN is
configured.
6.
(Optional.) Specify the failover IP
address and dialer string.
voice-config fail-over
ip-address
dialer-string
By default, no failover IP
address or dialer string is
specified.
Configuring self-defined DHCP options
IMPORTANT:
Use caution when configuring self-defined DHCP options because the configuration might affect DHCP
operation.
You can self-define options for the following purposes:
•
Add newly released options.
•
Add options for which the vendor defines the contents, for example, Option 43.
•
Add options for which the CLI does not provide a dedicated configuration command. For example,
you can use the
option 4 ip-address 1.1.1.1
command to define the time server address
1.1.1.1 for
DHCP clients.
•
Add all option values if the actual requirement exceeds the limit for a dedicated option
configuration command. For example, the
dns-list
command can specify up to eight DNS servers.
To specify more than eight DNS servers, you must use the
option 6
command to define all DNS
servers.
To configure a self-defined DHCP option in a DHCP address pool:
Step

Remarks
1.
Enter system view.
