DOCSIS 2 & 3 Cable Modems Support


DOCSIS is a Standard and as such I imagine that almost any cable modem could be used, I have noticed some difference over the years between models / vendors. So i have provided the 4 models I commonly use & sample output from each.

Models Currently In Use:
-Motorola SB5101
-Motorola SB6180
-Motorola SBG6580
-Arris DG1674

Sample Output:
SB5101 -
SB6180 -
SBG6580 -
DG1670A -

Items to be Counted / Graphed:

SNMP-Walk Output:

Layer 1 Info;
-These don’t really need to be graphed - Something more of an event history would suffice - also the existing Ports / Overview page already shows Up/Down - but associating the mib/oid with the interfaces is important
-Mac Address’s
-BRIDGE-MIB::dot1dTpFdbAddress.’ .d…g’ = STRING: 20:e5:64:ff:db:67 #### CABLE MODEM MAC ADDRESS
-BRIDGE-MIB::dot1dTpFdbAddress.‘l…’ = STRING: 6c:19:8f:f3:99:95 #### DEVICE BEHIND THE MODEM

-Ethernet Status & Last State Change
SNMP Walk output:

-Traffic with Total in Mb,Gb etc… ( I imagine something existing can be used for this )

Please let me know if you require any additional information or output.

Thank you.


I would find this incredibly useful for one of my clients.
