Hi
In our ubr10k the downstreams are used indidually by docsis 1.1 and 2.0 modems
and are also used in wideband interface for docsis 3 modems
how can we monitor for congestion ?
we have 4 downstreams and 1 wideband interface
for example
ds1 is used at 50% by docsis2 modems
ds2 is used at 40% by docsis2 modems
ds3 is used at 30% by docsis2 modems
ds4 is used at 40% by docsis2 modems
ds1 is used at 50% by docsis3 modems
ds2 is used at 30% by docsis3 modems
ds3 is used at 30% by docsis3 modems
ds4 is used at 40% by docsis3 modems
we have congestion on ds1
is there a snmp interface I can read that will show me the 100% utilization ?
note: I cannot see the ds1 dcsis3 percentage so I can't add the two to get the 100%
hello
for every cisco architecture you have an rf interface with snmp values that count output bits of your frequency.
if you have external rfgateway you need to poll the device else you have a dedicated interface.
after you will need to remove docsis 1.1 from the total.
could you precise which architecture you use? or give the list of your interfaces?
we use cisco ubr10012 with mc20x20 cards
here is an example of the snmpwalk
IF-MIB::ifDescr.1016 = STRING: Cable5/1/0
IF-MIB::ifDescr.1961 = STRING: Wideband-Cable5/1/0:0
IF-MIB::ifDescr.1993 = STRING: Integrated-Cable5/1/0:0
IF-MIB::ifDescr.1994 = STRING: Integrated-Cable5/1/0:1
IF-MIB::ifDescr.1995 = STRING: Integrated-Cable5/1/0:2
IF-MIB::ifDescr.1996 = STRING: Integrated-Cable5/1/0:3
IF-MIB::ifDescr.6841 = STRING: Integrated-Cable5/1/0-downstream0
IF-MIB::ifDescr.6842 = STRING: Integrated-Cable5/1/0-downstream1
IF-MIB::ifDescr.6843 = STRING: Integrated-Cable5/1/0-downstream2
IF-MIB::ifDescr.6844 = STRING: Integrated-Cable5/1/0-downstream3
IF-MIB::ifDescr.8041 = STRING: Cable5/1/0-upstream0
IF-MIB::ifDescr.8042 = STRING: Cable5/1/0-upstream1
IF-MIB::ifDescr.8043 = STRING: Cable5/1/0-upstream2
IF-MIB::ifDescr.8044 = STRING: Cable5/1/0-upstream3
I guess the ones to watch are
IF-MIB::ifDescr.6841 = STRING: Integrated-Cable5/1/0-downstream0
IF-MIB::ifDescr.6842 = STRING: Integrated-Cable5/1/0-downstream1
IF-MIB::ifDescr.6843 = STRING: Integrated-Cable5/1/0-downstream2
IF-MIB::ifDescr.6844 = STRING: Integrated-Cable5/1/0-downstream3
our monitoring software seems to ignore those interfaces so I don't have any data
I will verify that
thanks
yes
docsis3 traffic:
IF-MIB::ifDescr.1961 = STRING: Wideband-Cable5/1/0:0
docsis 1.1 traffic:
IF-MIB::ifDescr.1993 = STRING: Integrated-Cable5/1/0:0
IF-MIB::ifDescr.1994 = STRING: Integrated-Cable5/1/0:1
IF-MIB::ifDescr.1995 = STRING: Integrated-Cable5/1/0:2
IF-MIB::ifDescr.1996 = STRING: Integrated-Cable5/1/0:3
RF traffic:
IF-MIB::ifDescr.6841 = STRING: Integrated-Cable5/1/0-downstream0

IF-MIB::ifDescr.6844 = STRING: Integrated-Cable5/1/0-downstream3
you have it
Have a look at the info here
