Adding a Logical Unit Description to the Configuration
You can include a text description of each logical unit in the configuration file. Any descriptive text you include is displayed in the output of the show interfaces commands, and is also exposed in the ifAlias Management Information Base (MIB) object. It has no impact on the interface’s configuration. To add a text description, include the description statement:
You can include this statement at the following hierarchy levels:
- [edit interfaces interface-name unit logical-unit-number]
- [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
The description can be a single line of text. If the text contains spaces, enclose it in quotation marks.
 | Note: You can configure the extended DHCP relay to include the interface description in the option 82 Agent Circuit ID suboption. See “Enabling and Disabling Insertion of Option 82 Information” in the Junos OS Subscriber Management, Release 12.3. |
