Generally, device versions have matching NMS software. The NMS software needs to apply to all the devices supported by matching versions. Otherwise, the NMS cannot manage devices. If the NMS version is an earlier version but the current device is running a later version that does not match the current NMS version, the NMS cannot manage the current device.
To decouple the NMS version and device version, a compatible device model developed based on an earlier version is defined for each device model. If the NMS cannot manage a device because of version mismatch, obtain information about the device compatible with the current device. The NMS can then use the obtained information to manage the current device.
For example:
S5720-SI_R10 is a device model newly available in V200R010. The NMS software version that matches the device software version is V200R010.
S5720-SI_R8 is a device model newly available in V200R008. The NMS software version that matches the device software version is V200R008.
When you use the NMS of V200R008 to manage S5720-SI_R10, the device cannot be managed because of version mismatch. The NMS then obtains compatibility information about S5720-SI_R10 and learns that it is compatible with S5720-SI_R8. Subsequently, the NMS uses information about S5720-SI_R8 to manage the current device.
If the device does not have a compatible version, the system will display a message, indicating that no compatible information exists after the display compatible-information command is executed.
Compatible information of stacked devices can also be displayed.
