Hi All,
I am running docsis 1.1 with cisco ubr7200VXR IOS 12.2(33)SCE5, with modem motorola SB5101i. I am using static service flow with two service (voice and data). I made clasifier based on udp port of voice. the plant testing is: phone and pc (both of them will get IP DCHP) connected to router (nat), router conected to modem. the result is modem and pc already get IP DCHP from router, but when I do call and browsing, both of them traffic comes in to primary DS dan US.
my configuration in CMTS:
cable service class 50 name primary_ds
cable service class 50 downstream
cable service class 50 max-rate 1000000
cable service class 51 name voice_ds
cable service class 51 downstream
cable service class 51 max-rate 110000
cable service class 51 priority 7
cable service class 90 name primary_us
cable service class 90 upstream
cable service class 90 sched-type 2
cable service class 90 max-rate 1000000
cable service class 91 name voice_us
cable service class 91 upstream
cable service class 91 sched-type 6
cable service class 91 req-trans-policy 1F
cable service class 91 grant-size 235
cable service class 91 grant-interval 20000
cable service class 91 grant-jitter 1000
cable service class 91 grants-per-interval 1
same at this in config file, include classifier based on wire shark, port udp RTP : Source 12626 destination 11784 .
hopefully some one can help me for this,
THank You,
as far as I know used RTP no fixed source port, but all highports.
and that source nat on the router changes the used port again.
thanks, how can I define RTP Port in config file? cause all traffic stil comes to primary DS and US.
In the CM Configfile not.
Maybe the router don't changes the ToS field of the phone packages and you can used for classifier.
I use a CM with built-in MTA. For example Motorola SBV5121E.
Then I give the MTA another ip subnet.
e.g. 10.0.1.0/24 for the CM, 10.0.2.0/24 for the MTA, 10.0.3.0/24 for the CPE/Host.
And 10.0.0.254 is the SIP Server.

Thank You, I dont know yet dan not configure anything about ToS, should do something about ToS?

maybe this link will help you
http://www.cmtsinfo.net/index.php?howto=cm_config
and in this Cablelabs Document, Annex C, you find all TLV's
http://www.cablelabs.com/specifications/CM-SP-MULPIv3.0-I18-120329.pdf
Does all the voice traffic go to a server? (eg Asterisk). If so, you could setup your classifier to match on that IP.
Wouldn't work though if your calls are peer-to-peer style.
If you do a lot of voice stuff, then I would definitely recommend you look at using eMTA rather than cm + external ATA. Using an eMTA opens up many options for QoS.
Of course, this only works with a RTP Proxy!
e.g. Asterisk or openSIPS, openSER, Kamailio + rtpproxy.
I use the eMTA Motorola SBV5121E D2.0 with SIP Firmware... can i do it better?
Can i tag the RTP Traffic?
Thanks, it works now!, after i changed the classifier based on IP Proto 17 (UDP) with destination/source IP Voice Server/RTP Proxy from port 5061 to 65535.

Hello grosche,
Can you please send me a sample of config file for mta? do you make fw upgrade for your modems to sip protocol?
i can't get modem uploaded by fw. husame(@)gmail.com
thanks
Yes, you must upgrade the Firmware to the SIP Version "SBV5121E-SIP-1.0.7-SCM-06-SHPC".
After encode the file with the docsis tool, you must insert the correct sha1sum on the last line before MtaConfigDelimiter 255
and encode the file again.
(e.g. SnmpMibObject pktcMtaDevProvConfigHash.0 HexString 0xbfac8a00a1f5e98f71c93ded50291738a0047157;)
You need the GI-BTI-MIB and the PKTC-IETF-MTA-MIB draft from January 21, 2005 with
::= { enterprises tComLabs(7432) 1 }
or replaced
SnmpMibObject pktcMtaDevEnabled.0 -->> SnmpMibObject enterprises.7432.1.1.1.6.0
SnmpMibObject pktcMtaDevProvConfigHash.0 -->> SnmpMibObject enterprises.7432.1.1.2.9.0
RFC 4682 from September 18, 2006 don't work with this Firmware.
You can upgrade the Firmware over SNMP or a CM Configfile.
I use the DHCP-Server for a automatic Firmware check and upgrade.

Is it possible to send me the fw and certificates for this modem sbv5121E? and mibs?
i will be greatfull.
how do create the hash (e.g. SnmpMibObject pktcMtaDevProvConfigHash.0 HexString 0xbfac8a00a1f5e98f71c93ded50291738a0047157;) and what is this hash used for?
Thanks.
The MTA checks so that the transfer of the configuration file is correct.
#!/bin/bash
# example: me.sh mta.txt mta.bin
TXTFILE=$1
BINFILE=$2
cp $TXTFILE $TXTFILE.tmp
docsis -p $TXTFILE.tmp $BINFILE 2>/dev/null
HASH=$(sha1sum $BINFILE | cut -d " " -f1)
sed -i "s/MtaConfigDelimiter 255;/SnmpMibObject pktcMtaDevProvConfigHash.0 HexString 0x$HASH;\n\tMtaConfigDelimiter 255;/g" $TXTFILE.tmp
docsis -p $TXTFILE.tmp $BINFILE 2>/dev/null
rm $TXTFILE.tmp
can i have the fw & mibs please? husame( at )gmail.com
