Separating management traffic

I wanted to be able to set up a service flow or whatever it would be so that I would be able to poll modem information from a management server but not have the customer's current usage affect my ability to pull info.

We currently just have a single service flow set up for whatever the customer's level of service is. This becomes an issue when they are using a ton of upload and I am unable to poll the modem.

We are running a Motorola BSR64000 app 6.4.2.3 bootrom 6.0.0.52

yep, easy to do

yep, easy to do

in your cm config file you need to do something like this

/* PRIMARY */

DsServiceFlow
{
DsServiceFlowRef 1;
QosParamSetType 7;
ServiceClassName "XXMBPS-DS";
}
UsServiceFlow
{
UsServiceFlowRef 2;
QosParamSetType 7;
ServiceClassName "XXMBPS-US";
}

/* MANAGEMENT */

DsServiceFlow
{
DsServiceFlowRef 11;
QosParamSetType 7;
ServiceClassName "MGT-DS";
}
UsServiceFlow
{
UsServiceFlowRef 12;
QosParamSetType 7;
ServiceClassName "MGT-US";

}

/* management servers */
DsPacketClass
{
ServiceFlowRef 11;
ClassifierRef 21;
ActivationState 1;
IpPacketClassifier
{
IpSrcAddr x.x.x.0;
IpSrcMask 255.255.255.192;
}
}
UsPacketClass
{
ServiceFlowRef 12;
ClassifierRef 22;
ActivationState 1;
IpPacketClassifier
{
IpDstAddr x.x.x.0;
IpDstMask 255.255.255.192;
}
}

notes :
* the first pair of service flows are the "default flows". This is where traffic that doesnt match any classifier rules will go. So general internet will go through here.
* my example uses ServiceClassName which is an abstraction referring to service-classes defined on the CMTS. You could replace that by putting the various settings like max-rate, priority etc directly into the config file instead
* for the addr/mask, you could match against the subnet where your management stations live, or I guess you could match against the CM IP subnets. Probably matching against the management stations is better, as then it wont matter if you are SNMP polling CM IP, MTA IP, CPE IPs etc
* Make sure you allocate enough speed to the management flows to allow things like firmware upgrades to run at a reasonable speed

Hope that helps!
