Release Information
Statement introduced in Junos OS Release 17.2 for QFX Series switches.
Description
Enable the use of a custom text string as the interface description in the DHCP base option 82 Agent Circuit ID (suboption 1) information. This text string is defined independently of the interface description that is configured using the description statement at the [edit interfaces interface-name] hierarchy level.
The custom text string is configured using the user-defined-option-82 statement at the following hierarchy levels:
- To configure a custom string on an interface level: [edit forwarding-options dhcp-relay group group-name interface interface-name overrides user-defined-option82 string]
- To configure a custom string at the group level:[edit forwarding-options dhcp-relay group group-name overrides user-defined-option82 string]
- To configure a custom string globally: [edit forwarding-options dhcp-relay overrides user-defined-option82 string]
When you enable the custom text string, other options for the Circuit ID cannot be configured. For example, you cannot configure the prefix statement with the user-defined statement.
Default
If you do not configure the user-defined statement, the custom text string is not included in the DHCP option 82 Circuit ID.
