Huawei Switch MAC Address Table

A scripted ConfigSource should work. The thing about LM is that it's not really built for interacting with the devices just once in a while. You'd need to build the configsource to log in regularly and issue the show commands. You wouldn't have to set any config checks on it, unless you really wanted to. The configsource would pull back the results of the show commands (using Expect) and store them in LM. Then your users could see the output of the command without ever logging into the device.
