The isis enable command enables IS-IS on an interface and associates an IS-IS process ID with the interface.
The undo isis enable command disables IS-IS from an interface and dissociates the IS-IS process ID from the interface.
By default, IS-IS is not enabled on an interface.
| Parameter | Description | Value |
|---|---|---|
| process-id | Specifies the IS-IS process ID to be associated with the interface. |
The value is an integer ranging from 1 to 65535. By default, it is 1. |

Usage Scenario
After an IS-IS process is configured in the system view, you need to run the isis enable command in the interface view to enable IS-IS on the interface and associate the interface with the process so that IS-IS can work properly.
Prerequisites
An IS-IS process has been enabled using the isis command in the system view.
# Create IS-IS process 1, enable IS-IS on GigabitEthernet0/0/0, and associate the interface with process 1.
<sysname> system-view
