(Optional) Configuring the DHCP User Name and Password


The DHCP user name and password must be configured during server authentication.


  1. Run system-view

    The system view is displayed.

  2. Run dhcp user-name format-include { ip-address | mac-address | option82 | sysname } *

    The DHCP user name format and the sequence of elements in the user name are specified.

    By default, the DHCP user name is in the following format: system name + "-" + slot ID (two digits, prefixed 0 if it contains only one digit) + subcard ID (one digit, set to 0 if the subcard does not exist) + port number (two digits, prefixed 0 if it contains only one digit) + outer VLAN ID (four digits, prefixed 0 if it contains fewer than four digits) + inner VLAN ID (five digits, prefixed 0 if it contains fewer than five digits) + @ + access domain name, for example, HUAWEI-02024000000768@domain1.

    If the user name is generated according to the Option 82 field and the user name contains non-ASCII characters, the non-ASCII characters are displayed as "..." for example, ...session1@domain1.

  3. Run dhcp user-password cipher password

    The DHCP user password is set.

    By default, the DHCP user password is vlan.


    To ensure device security, change the password periodically.
