Customizing Dhcp Options - HP FlexNetwork MSR2003 Configuration Manual

Step
3. Specify the IP address of the
primary network calling
processor.
4. (Optional.) Specify the IP address
for the backup server.
5. (Optional.) Configure the voice
VLAN.
6. (Optional.) Specify the failover IP

Customizing DHCP options

IMPORTANT:
Use caution when customizing DHCP options because the configuration might affect DHCP
operation.
You can customize 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 customize a DHCP option in a DHCP address pool:
Step
1. Enter system view.
2. Create a DHCP address
pool and enter its view.
3. Customize a DHCP
option.
To customize a DHCP option in a DHCP option group:
Step
1. Enter system view.
2. Create a DHCP user
class and enter DHCP
user class view.
