Variables Name Description Defaults mac Cable Modem MAC sid Cable Modem SID interface Cable interface
Related Events Network | DOCSIS | Bad Timing Offset Probable Causes The cable modem is not using the correct starting offset during initial ranging, causing a zero, negative timing offset to be recorded by the CMTS for this modem. The CMTS internal algorithms that rely on the timing offset parameter will not analyze any modems that do not use the correct starting offset. The modems may not be able to function, depending on their physical location on the cable plant.
Recommended Actions Locate the cable modem based on the MAC address and report the initial timing offset problem to the cable modem vendor.

Related Events Network | DOCSIS | Maximum Capacity Reached Probable Causes The currently reserved capacity on the upstream channel already exceeds its virtual reservation capacity, based on the configured subscription level limit. Increasing the subscription level limit on the current upstream channel will place you at risk of being unable to guarantee the individual reserved rates for modems since this upstream channel is already oversubscribed.
Recommended Actions Load-balance the modems that are requesting the reserved upstream rate on another upstream channel.
