Cisco Bug: CSCuq79212 - Config entered on deleted controllers lost from the system
Jul 30, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: Config committed under a nV Optical controller can be lost if committed the same time as the controller is being deleted. Note that, since the controller is being deleted, this has minimal immediate impact on the system: the only effect is that the deleted controller has incorrect 'preconfig'. For example, in the config commit below, 'no transponder 100 3/0/2' causes Optics100/3/0/2 to be deleted. The expected behaviour is that the new 'wavelength 4' config is moved to preconfig ('controller preconfigure Optics100/3/0/2 wavelength 4'). Instead, the 'wavelength 4' config is lost from the system. RP/0/0/CPU0:ios(config)#show conf ... nv satellite 100 no transponder 100g 3/0/2 ! ! controller Optics100/3/0/2 wavelength 4 ! end RP/0/0/CPU0:ios(config)#commit RP/0/0/CPU0:ios(config)#show run ... nv satellite 100 type ons15454-m6 ! ! controller preconfigure Optics100/3/0/2 shutdown ! end Conditions: Seen in any single config commit that: 1. Includes configuration under a nV Optical controller. 2. Causes that controller to be deleted. Controllers can be deleted in a number of ways: 1. Removing 'transponder' or 'muxponder' configuration. 2. Adding 'transponder' or 'muxponder' configuration that's incompatible with an existing transponder/muxponder. 3. Removing satellite 'type' configuration. 4. Removing or changing an Optics controller's 'portmode' configuration.
