Re: Information from router What does this info mean?

OK then 

RCS (Receive Channel Set) Partial Service. The hub ‘knows’, for example that it should have 24 bonded downstream channel but for some reason, generally noise or interference, it is unable to properly lock onto one or more of them. If this happens then rather than the hub simply going offline, it carries on with a slightly degraded service - which may or may not even be noticeable to the user. If and when the conditions improve, the hub will recover it’s full service although this isn’t logged. Getting some of these infrequently is not uncommon and can usually be ignored.

As I said, there will be a number of downstream channels and the hub need to know which if these is the primary channel to lock onto. To do this, information is periodically included in all of the downstream channels to let the hub know which to use. This is especially important when the hub first starts up but needs to be periodically resend. This information (along with other data that the hub uses to adjust itself) is called the Mac Domain Descriptor (MDD), and the message is simply saying that the hub hasn’t managed to receive a fresh copy of the MDD within the required period, it’s basically timed out - as per the wording of the message.

Again if you just get a couple of these from time to time, there’s no need to be concerned - like the RCS messages, they are more warnings than actually error messages.

So as @jbrennand says are you experiencing any issues with your service or were you just curious as to what they mean?

Oh and if you see actual error messages about DHCP, these really can be ignored as they aren’t error messages at all and VM really should suppress them.
