TWCGPON657 bandwidth limit to 30Mbps #35

ccy · 2022-05-13T10:14:56Z

My ISP is Maxis 100Mbps package.

I am using TWCGPON657 SFP stick. I flash the firmware to C00R657V2801F_V1.9.0-220404.tar.

I also follow the instruction perform necessary setup for the SFP stick. I am able to connect to the ISP via PPPoE.

However, when perform speedtest. The download speed cap at 30Mbps and upload is below 1Mbps.

Plug the fiber cable back to original Maxis/TM GPON, the speed is usual 100M/50M.

I also make sure the SFP port of network switch is set to 1000M.

This is the Chipset of the GPON stick:

# cat /proc/cpuinfo
system type             : RTL8672
processor               : 0
cpu model               : 56322
BogoMIPS                : 112.23
tlb_entries             : 64
mips16 implemented      : yes

Any steps I didn't do right?

oh that's very odd...

have you copy old ONU into to new stick? clone OMCI info to trick OLT,

also, can you print and paste your bandwidth status like this
https://github.com/Anime4000/RTL960x/blob/main/Docs/DIAG.md#bandwidth

ccy · 2022-05-14T04:03:33Z

I only copy the PLOAM password over. Is it enough?

bandwidth is fine...

With TM fiber, you need correct Hardware Version, then OLT give correct OMCI Parameters

Unifi HG8240H5 ONU Hardware Version:

flash set HW_HWVER 168D.A

since you using V2801F firmware on TWCGPON657, you need generate VS_AUTH_KEY

give me your ONU Model, Stick MAC Address, I make one

ccy · 2022-05-14T09:11:16Z

This is my current setting:

# flash get HW_HWVER
HW_HWVER=168D.A
# flash get GPON_ONU_MODEL
GPON_ONU_MODEL=HG8240H5
# flash get ELAN_MAC_ADDR
ELAN_MAC_ADDR=6cefc6bed812
# flash get VS_AUTH_KEY
VS_AUTH_KEY=7e,c8,c9,dc,c0,23,54,85,1d,c2,32,80,36,8f,2f,af,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00

After reboot, my GPON stick will enter O5 state, so I assume it works.

However, my download/upload bandwidth still cap at 30M/1M

Anime4000 · 2022-05-14T09:48:00Z

try this:

flash set GPON_ONU_MODEL HG8240H5
flash set GPON_SN HWTC12345678
flash set PON_VENDOR_ID HWTC
flash set OMCI_SW_VER1 V5R019C00S125
flash set OMCI_SW_VER2 V5R019C00S125
flash set OMCI_OLT_MODE 1
flash set OMCI_FAKE_OK 1
flash set HW_CWMP_MANUFACTURER 'Huawei Technologies Co., Ltd'
flash set HW_CWMP_PRODUCTCLASS HGU
flash set HW_HWVER 168D.A
flash set ELAN_MAC_ADDR 6cefc6bed812
flash set VS_AUTH_KEY 7EC8C9DCC02354851DC23280368F2FAF

This should work with TM, this making your stick like Huawei ONU,
Allo and TIME Fiber just works

ccy · 2022-05-14T09:57:50Z

No luck after execute your script. I assume these two lines has typo mistake:

flash get OMCI_OLT_MODE 1
flash get OMCI_FAKE_OK 1

I have changed to set when executing.

Anime4000 · 2022-05-14T09:58:46Z

my bad...

after enter these flash set have you tried to reboot?

ccy · 2022-05-14T10:02:27Z

Yes, I reboot before I try after execute those flash set command.

ccy · 2022-05-14T10:16:54Z

I also try to plug the GPON stick to another old model L2 switch, still the same.

Anime4000 · 2022-05-14T10:50:55Z

that's very odd, what kind of switch are you using?

ccy · 2022-05-14T12:50:47Z

S5860-20SQ
DGS-1210-20

Anime4000 · 2022-05-14T20:18:23Z

V2801F using 1000baseX
it's works well with RB3011 and Fortigate but not RB5009

have other SFP host or PCIe SFP to test?

ccy · 2022-05-14T21:53:21Z

I don't have RB3011 and Fortigate. Is MikroTik ok?

Anime4000 · 2022-05-15T07:34:59Z

Yes, Mikrotik RB5009 is currently I using with ODI DFP-34X-2C2 (TM-Maxis 500/100 Plan)

RB3011 + TWCGPON657 now at my friend home, TIME 500mbps

ccy · 2022-05-15T08:19:20Z

I have CRS326-24G-2S+. Will try tomorrow.

Anime4000 · 2022-05-15T08:40:58Z

Yes, PON Stick have limited SFP Host support, RTL960x firmware kind picky which router and switch

ccy · 2022-05-16T04:28:33Z

I have test all other switches I have.

Fail to detect the GPON stick:

MikroTik CRS326-24G-2S+ cannot detect the GPON stick at all.

These switches can ping to the GPON stick but fail to ping once plug in TM fiber cable:

These switches can ping to GPON Stick, can establish PPPoE connection, can serve Internet but limited to 30Mbps down/1Mbps up:

Do you face the same problem on TWCGPON657?

Anime4000 · 2022-05-16T10:05:13Z

wow, you have a lot of switches...

What I know, RTL9601B, RTL9601CI, RTL9601D has 1000base-T LAN_SDS_MODE 0 and 1000base-X LAN_SDS_MODE 1

Meanwhile other LAN_SDS_MODE value, is SGMII and HiSGMII, which is require SFP to have intermediate MII translation chipset to Ethernet. I afraid that not all Switch and Router support MII

but you can try:

echo 0 > /proc/lan_sds/lan_sds_cfg
echo 2 > /proc/lan_sds/lan_sds_cfg
echo 3 > /proc/lan_sds/lan_sds_cfg

Here my Mikrotik RB5009 + ODI DFP-34X-2C2

# cat /proc/lan_sds/lan_sds_cfg
lan_sds_mode = 3(SGMII MAC)
# flash get LAN_SDS_MODE
LAN_SDS_MODE=0

Value are not match, ODI DFP-34X-2C2 can auto nego with host with appropriate mode

However, you can buy this as MII translation: Hellotek T8501S

Or buy ODI DFP-34X-2C2 with Mikrotik CRS305-1G-4S+IN or CCR2004-1G-12S+2XS, 100% compatible including 2.5Gb support!!!

ccy · 2022-05-16T10:54:14Z

I prefer direct plug the GPON stick to my L2/L3 switch so I reduce a 12VDC power adapter to power the external device like TM's Huawei GPON.

Anime4000 · 2022-05-16T12:03:59Z

I understand, I just to make sure that TWCGPON657 have an issue or something else,
I afraid TWCGPON657 that you have is different hardware revision...

Mikrotik Router CCR2004-1G-12S+2XS and CRS305-1G-4S+IN Switch currently full supported, it has Port Extender which can support various MII (SGMII & HiSGMII) and base-X

meantime, try this command if got any different

echo 0 > /proc/lan_sds/lan_sds_cfg
echo 2 > /proc/lan_sds/lan_sds_cfg
echo 3 > /proc/lan_sds/lan_sds_cfg

ccy · 2022-05-16T12:56:11Z

How to identify the hardware of my GPON stick?

Anime4000 · 2022-05-16T16:34:00Z

How to identify the hardware of my GPON stick?

this you need disassemble and compare

ccy · 2022-05-17T00:29:56Z

I try these command:

echo 0 > /proc/lan_sds/lan_sds_cfg
echo 2 > /proc/lan_sds/lan_sds_cfg
echo 3 > /proc/lan_sds/lan_sds_cfg

Once execute, the GPON stick immediately freeze and no response. Need to unplug and plug to reboot.

This is the default value:

# cat /proc/lan_sds/lan_sds_cfg
lan_sds_mode = 1(Fiber 1G)

ccy · 2022-05-24T14:37:47Z

I bought a new ODI DFP-34X-2C2 GPON stick

$ cat /proc/cpuinfo
system type             : RTL8672
processor               : 0
cpu model               : 56322
BogoMIPS                : 299.00
tlb_entries             : 64
mips16 implemented      : yes

# cat /etc/version
V1.0-220304 --  Fri Mar 4 11:22:18 CST 2022

I didn't patch the firmware and direct enter my PLOAM password. I get connect to internet but the speed still remain at 30M download / 0.5M upload.

Should I patch the firmware? Which firmware should I patch?

Anime4000 · 2022-05-24T16:03:36Z

oh, you also bought ODI Stick which is using RTL9601D, where TWCGPON657 using RTL9601CI

both produce slow and odd speed.

there are no firmware to fix it, it seem your SFP host having compatibility issues with Realtek SGMII.

alternatively get MA5671a stick with OpenWRT, but I no guarantee compatible with your existing device, but can try

Anime4000 · 2022-05-24T16:05:31Z

since you have ODI Stick, try changing LAN_SDS_MODE

0 = 1GbaseT
1 = 1GbaseX
2 = SGMII PHY
3 = SGMII MAC

ccy · 2022-05-25T04:05:17Z

Try these modes and same issue too:

flash set LAN_SDS_MODE 0
reboot

flash set LAN_SDS_MODE 1
reboot

flash set LAN_SDS_MODE 2
reboot

flash set LAN_SDS_MODE 3
reboot

And I found that I can't change OMCI_SW_VER1 and OMCI_SW_VER2:

# flash get OMCI_SW_VER1
OMCI_SW_VER1=V1.0-220304
# flash get OMCI_SW_VER2
OMCI_SW_VER2=V1.0-210702

Anime4000 · 2022-05-25T05:44:33Z

if 0 until 3 produce same effect, highly chance that SFP Host having issue,

I have no idea how fix it 😅

yea, ODI have hard coded sw version,
for Telekom Malaysia OLT, doesn't care about it, only care HW Ver,

it will get O5 no matter what, since stock ISP ONU have own provisioning,

ccy · 2022-05-25T06:27:06Z

Even if I use different HW_HWVER, I still can get O5 and connect to internet.

ccy · 2022-05-25T09:27:08Z

I further debug the issue. I found out the GPON ignore my value set to LAN_SDS_MODE. It will also reset to 1.

# flash get LAN_SDS_MODE
LAN_SDS_MODE=2

# cat /proc/lan_sds/lan_sds_cfg
lan_sds_mode = 1(Fiber 1G)

And this is the /proc/kmsg output:

Anime4000 · 2022-05-25T16:03:04Z

Yes, ODI Stick has Auto Negotiation, it will auto switch to find right LAN_SDS_MODE

in my RB5009:

# cat /proc/lan_sds/lan_sds_cfg
lan_sds_mode = 3(SGMII MAC)
# flash get LAN_SDS_MODE
LAN_SDS_MODE=0

It seem your device only accept 1000baseX

ODI has another mode, flash set LAN_SDS_MODE 7, it will force SGMII mode, try that

tdmadam · 2022-05-25T18:23:51Z

Have you checked the VLANs and UNI port mapping? 30Mbps/1Mbps makes sense for VoIP or management VLANs, but not for Internet services. In some countries, users also saw low speeds until they marked the appropriate priority bits(PCP).

Turn off OMCI_FAKE_OK, turn on OMCI readable log(par) and see if you see many errors.
Is the IP address in the same range like original Maxis/TM ONT?
Make sure that the hardware, software version and other parameters are exactly the same as the original.
What is your OLT? omcicli mib get 131 Does it match OLT mode?

There is a nice picture of the Maxis network showing VLANs and port mapping:

After some trial and error and play around with variaous settings. I finally got it working at 100M/50M. I execute this

flash set OMCI_TM_OPT 0
reboot

OMCI_TM_OPT

0: priority controlled
1: rate controlled
2. priority and rate controlled

Anime4000 · 2022-05-26T09:45:35Z

@ccy wow, this is new...

during my testing on OMCI_TM_OPT on my fiber, it doesn't do anything, I have been wondering what is this...
with TM-Maxis currently I use, trying 0, 1, 2 give same results, so that time I not sure this can cause speed slow down:

I have updated info about this:
https://github.com/Anime4000/RTL960x/blob/main/Docs/FLASH_GETSET_INFO.md#omci_tm_opt-min-0-max-2-default-is-2

ccy · 2022-05-26T14:04:50Z

@Anime4000, as TM/Maxis provide asymmetric upload/download bandwidth. Possible to make it same? 100 up / 100 down? Or 500/500?

Anime4000 · 2022-05-26T14:28:35Z

@ccy
I have tried swapping Maxis and Unifi PPPoE Account.

Home with Unifi 100/50 subscription:
I swap with 800/200 pppoe account and do get 800+ in speedtest

Home with Maxis 500/100 subscription:
I tried with 800/200 pppoe account and speed still same...

This mean:
For Unifi, TM OLT didn't set bandwidth limit, only limited via PPPoE

For Maxis under TM fiber, TM OLT do set bandwidth limit, using higher speed PPPoE account will get speed limit at OLT (L2)

but this varied place to place, how TM configure.

like yours, OMCI_TM_OPT has effect your speed meanwhile mine remain same effect with any value.

but you can try access diag utility in telnet and try play with

ccy · 2022-05-27T02:29:05Z

I bought the GPON stick from here

Anime4000 · 2022-05-28T19:03:57Z

@ccy

tonight I tried again OMCI_TM_OPT 0, 1, 2

Results:
OMCI_TM_OPT 0

OMCI_TM_OPT 1

OMCI_TM_OPT 2

with 0 (priority controlled) mode, my speed never reach 500Mbps, always under 400 or worst

with 1 (rate controlled) mode, my speed can over 500Mbps

with 2 (both) mode, my speed still can over 500Mbps, but I stick with 1

May I know, Allo ISP working with this hardware ODI DFP-34X-2C2 with Mikrotik CRS305-1G-4S+IN as you mention?

and what type SFP need to buy GPON, XPON or EPON?

choose XPON
Allo should work

@Anime4000 , it is me again facing speed issue.

Previously I subscribed to 100M/50M maxis package, and the download speed from the GPON is 30M. Then I set OMCI_TM_OPT=0 and I can get 100M/50M bandwidth.

Now I upgrade my plan to 500M/100M, and my speed stay in 100M/50M, using the GPON from the ISP, I can get 500M/100M. Any idea?

Anime4000 · 2022-12-30T13:53:45Z

have you try other OMCI_TM_OPT value? 1 or 2 ?
I am using 2 as Maxis 500/100 under Unifi line

ccy · 2022-12-30T15:03:39Z

Yes, I have tried 0, 1, 2. All speed remain 100M/50M.

Anime4000 · 2022-12-30T15:43:44Z

try change the ONU information to something else, I afraid OLT locks on something, also try update to newer firmware

ccy · 2022-12-31T01:22:06Z

Where to get latest firmware?

This is my current firmware version:

# flash get OMCI_SW_VER1
OMCI_SW_VER1=V1.0-220414

# flash get OMCI_SW_VER2
OMCI_SW_VER2=V1.0-210702

Anime4000 · 2022-12-31T06:02:42Z

here
https://github.com/Anime4000/RTL960x/tree/main/Firmware/DFP-34X-2C2

maybe you can try change OMCC Version

ccy · 2022-12-31T06:04:59Z

I update GPON_SN=HWTC, and I get full bandwidth speed now:

flash set GPON_SN HWTC
flash set OMCI_TM_OPT 0

Anime4000 · 2022-12-31T06:30:03Z

your previous ONU is ALCL/Nokia?
It's best to use Huawei OMCI Information as most widely use for Universal ONU (brand interchangeable between OLT and ONU)

ccy · 2022-12-31T06:31:28Z

My previous ONU is huawei HG8240H5
