(Optional) Configuring a DHCP Option for the Global Address Pool

(Optional) Configuring a DHCP Option for the Global Address Pool


As DHCP develops, new options are emerging. To use these options, add them to the attribute list of the DHCP server manually. If the DHCP server is configured with the options, the DHCP client obtains the configuration of the options from the DHCP packet replied by the DHCP server when the client requests an IP address from the server.


  1. Run system-view

    The system view is displayed.

  2. Run ip pool ip-pool-name

    The global address pool view is displayed.

  3. Run option code [ sub-option sub-code ] { ascii ascii-string | hex hex-string | cipher cipher-string | ip-address ip-address &<1-8> }

    A user-defined option that a DHCP server assigns to a DHCP client is specified.

    No user-defined option is specified by default.

    • To ensure accuracy, read the standard protocols before configuring options.

    • When the password is contained in option, the ascii or hex type is insecure. Set the option type to cipher. A secure password should contain at least two types of the following: lowercase letters, uppercase letters, number, and special characters. In addition, the password must consist of six or more than six characters.

  4. Run option121 ip-address { ip-address mask-length gateway-address } &<1-8>

    A classless static route that a DHCP server assigns to a DHCP client is specified.

    No classless static route is specified by default.

  5. Run option184 { as-ip ip-address | fail-over ip-address dialer-string | ncp-ip ip-address | voice-vlan vlan-id }

    The Option184 that a DHCP server delivers to a DHCP client is specified.

    The Option184 is not specified by default.

  6. Run commit

    The configuration is committed.
