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 Command Remarks
1. Enter system view.
system-view
N/A
2. Create a DHCP address
pool and enter its view.
dhcp server ip-pool

3. Customize a DHCP
option.
option
code {
ascii
ascii-string |
hex
hex-string |
ip-address
ip-address&<1-8> }
By default, no DHCP option is customized in a
DHCP address pool.
DHCP options specified in DHCP option
groups take precedence over those specified in
DHCP address pools.
To customize a DHCP option in a DHCP option group:
Step Command Remarks
1. Enter system view.
