Adding a description to the interface from within ZebOS may cause interface level routing protocol commands to be lost on restart.
Interface level commands after the description will not appear in the imish running config and will not be loaded/functional.
- Add interface level description to a configuration with interface level routing protocol commands. - Restart services, tmrouted, or reboot.
To prevent this issue, do not use interface-level descriptions. If the issue has already occurred, and the configuration is not loading, you can manually correct it using the following procedure: 1. Stop tmrouted using the following command: bigstart stop tmrouted 2. Edit the ZebOS.conf from the corresponding route-domain file manually and remove the interface-level 'description' and 'no shutdown' commands. 3. Restart tmrouted using the following command: bigstart restart tmrouted. Note: Performing the workaround procedure will temporarily disrupt dynamic routing, so care and adequate planning must be taken into consideration.
Routing protocol interface commands are no longer lost with the addition of interface descriptions.
