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 f o r
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.
