I have a BSR64k and when I enable baseline privacy in my cable modem config files I get a ton of RF Errors In on just 2 brands of modems. The two modems are the Linksys CM100 and a Remstream. If I disable baseline privacy the errors go away. My average RF Errors In per second is around 2,000. These 2 modems represent a very small percentage of my total modems.
Has anyone seen this before?
What modulation profile are you configured for?
what's the snr on the upstream?
do those modems have current cert files and what is your bpi configured for on the modem file?
I recommend the modem be configured with:
17 (Baseline Privacy Configuration Settings Block)
S01 Author Wait Timeout = 10
S02 Re-auth Wait Timeout = 10
S03 Author Grace Timeout = 600
S04 Oper Wait Timeout = 10
S05 Re-key Wait Timeout = 10
S06 TEK Grace Time = 3600
S07 Auth Rej Wait Timeout = 60
S08 SA Map Wait Timeout = 10
S09 SA Map Max Retries = 10
18 (Maximum Number of CPE) = 4
29 (Privacy Enable) = 1
The modems are on a few different blades. One blade is MTDMA with modulation profile 104 which is: [code] Cable Modulation Profile 104 Description: DOCSIS 2.0-BRCM MTDMA Profile for Mixed Impulse Channel +--------------+------+------+------+------+------+------+------+------+ | | 1 | 3 | 4 | 5 | 6 | 9 | 10 | 11 | | IUC | Req | Init | Per | Short| Long | Adv | Adv | Adv | | | | Maint| Maint| Data | Data | Short| Long | UGS | +--------------+------+------+------+------+------+------+------+------+ Modulation qpsk qpsk qpsk 16qam 16qam 64qam 64qam 64qam Diff Encoding OFF OFF OFF OFF OFF OFF OFF OFF Preamble Len 64 640 384 72 80 88 96 96 FEC Err CRC 0 10 10 10 10 16 16 16 FEC CW Len 16 34 34 75 219 75 219 219 Scrambler Seed 338 338 338 338 338 338 338 338 Max Burst 0 0 0 8 0 6 0 0 Guard Time 8 48 48 8 8 8 8 8 Last Codeword FIXED FIXED FIXED SHORT SHORT SHORT SHORT SHORT Scrambler ON ON ON ON ON ON ON ON Intlv Depth 1 1 1 1 1 1 0 0 Intlv Blk Sz 0 0 0 0 0 0 2048 2048 Preamble Type QPSK0 QPSK0 QPSK0 QPSK0 QPSK0 QPSK1 QPSK1 QPSK1 SCDMA Spreader OFF OFF OFF OFF OFF OFF OFF OFF Codes Subfrm 0 0 0 0 0 0 0 0 Intlv Stp Sz 2 2 2 0 0 2 2 2 TCM Encoding OFF OFF OFF OFF OFF OFF OFF OFF Channel Type mtdma mtdma mtdma mtdma mtdma mtdma mtdma mtdma [/code] It is also happening on my TDMA blade with Modulation Profile 1: [code] Description: DOCSIS 1.X-TDMA 16-QAM & Transmit POST-EQ & FEC - for linear distor tion and impulse noise +--------------+------+------+------+------+------+------+------+------+ | | 1 | 3 | 4 | 5 | 6 | 9 | 10 | 11 | | IUC | Req | Init | Per | Short| Long | Adv | Adv | Adv | | | | Maint| Maint| Data | Data | Short| Long | UGS | +--------------+------+------+------+------+------+------+------+------+ Modulation qpsk qpsk qpsk 16qam 16qam Diff Encoding OFF OFF OFF OFF OFF Preamble Len 64 128 128 144 160 FEC Err CRC 0 5 5 5 10 FEC CW Len 16 34 34 78 235 Scrambler Seed 338 338 338 338 338 Max Burst 2 0 0 8 0 Guard Time 8 48 48 8 8 Last Codeword FIXED FIXED FIXED SHORT SHORT Scrambler ON ON ON ON ON Intlv Depth 1 1 1 1 1 Intlv Blk Sz 0 0 0 0 0 Preamble Type NONE NONE NONE NONE NONE SCDMA Spreader OFF OFF OFF OFF OFF Codes Subfrm 0 0 0 0 0 Intlv Stp Sz 0 0 0 0 0 TCM Encoding OFF OFF OFF OFF OFF Channel Type tdma tdma tdma tdma tdma [/code] The upstream SNR is good (above 25). It happens for just these two models of modems no matter what their SNR is (even if it is above 30). Regarding my config file, I inherited this config file from the previous admin: [code] GlobalPrivacyEnable 1; BaselinePrivacy { AuthTimeout 10; ReAuthTimeout 10; AuthGraceTime 600; OperTimeout 10; ReKeyTimeout 10; TEKGraceTime 600; AuthRejectTimeout 60; } [/code] I will try it with your Baseline settings and let you know what happens.
