1. Specify that you want to configure authentication options.
•
For DHCP local server:
[edit system services dhcp-local-server]
user@host# edit authentication
•
For DHCP relay agent:
[edit forwarding-options dhcp-relay]
user@host# edit authentication
•
For DHCPv6 local server:
[edit system services dhcp-local-server dhcpv6]
user@host# edit authentication
•
For DHCPv6 relay agent:
[edit forwarding-options dhcp-relay dhcpv6]
user@host# edit authentication
2. (Optional) Configure a password that authenticates the username to the external
authentication service.
See “Configuring Passwords for Usernames” on page 102.
3. (Optional) Configure optional features to create a unique username.
