Serial ​

The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface. To accept TX line commands, the GND of the TTL adapter should be attached to the stick's shield:

Note

Some USB TTL adapters label TX and RX pins the other way around: try to swap them if the connection doesn't work.

Useful files and binaries ​

Useful files ​

  • /var/config/lastgood.xml - Contains the user portion of the configuration

  • /var/config/lastgood-hs.xml - Contains the "hardware" configuration (which should not be changed)

  • /tmp/omcilog - OMCI messages logs (must be enabeled, see below)

Useful binaries ​

  • /etc/scripts/flash - Used to manipulate the config files in a somewhat safe manner
  • xmlconfig - Used for low-level manipulation of the XML config files. Called by /etc/scripts/flash
  • nv - Used to manipulate nvram storage, including persistent config entries via nv setenv/nv getenv
  • omcicli - Used to interact with the running OMCI daemon
  • omci_app - The OMCI daemon
  • diag - Used to run low-level diagnostics commands on the stick

GPON ONU status ​

Getting the operational status of the ONU ​

sh
diag gpon get onu-state

Querying a particular OMCI ME ​

sh
# omcicli mib get MIB_IDX

The list of the MEs is in GPON MIB, and the most useful ones to check the provisioning received from the OLT are in Most useful MEs to check the provisioning.

To dump all the MEs at once[1]:

sh

Getting the GEM ports and the flows ​

sh
# diag gpon show us-flow

    GPON ONU MAC U/S Flow Status
Flow ID | GEM Port | Type | TCont
      0 |      263 |  ETH |     0

     64 |        2 | OMCI |    16
============================================================
# diag gpon show ds-flow

Getting the VLANs bridged by the stick ​

The L2 table shows the learned MAC addresses with their VLAN (Vid): if the internet traffic arrives untagged on the router, this is a way to find which VLAN is used on the PON side[2].

sh
# diag l2-table get entry address valid

On the RTL9601D (e.g. ODI DFP-34X-2C2) the valid parameter is not available, the table has to be read entry by entry:

sh
i=0
while [ $i -lt 2047 ]; do
    diag l2-table get entry address $i | grep -q "LUT" && diag l2-table get entry address $i
    i=$((i+1))
done

Getting the port status and the bandwidth limits ​

sh
# diag port get status port all
Port Status Speed    Duplex TX_FC RX_FC
---- ------ -----    ------ ----- -----
0    Up     1000M    Full   Dis   Dis
2    Up     1000M    Full   Dis   Dis
# diag bandwidth get egress port all
# diag bandwidth get ingress port all

Getting/Setting Speed LAN Mode ​

Note

The default firmware does not allow modification of the LAN_SDS_MODE parameter. Using modded firmware is needed. Before editing the sync speed make sure your hardware supports it.

To change the link mode use this command:

sh
# /etc/scripts/flash get LAN_SDS_MODE
LAN_SDS_MODE=0
# /etc/scripts/flash set LAN_SDS_MODE 1
Valuecat /proc/kmsgModeBehavior
1<4>change mode to 1(Fiber 1G)FIBER1GbaseX with auto-neg on
2<4>change mode to 2(SGMII PHY)TP MII1Gb PHY
3<4>change mode to 3(SGMII MAC)MII1Gb MAC
4<4>change mode to 4(HiSGMII PHY)TP MII2.5Gb PHY
5<4>change mode to 5(HiSGMII MAC)MII2.5Gb MAC
6<4>change mode to 6(2500BaseX)FIBER2500baseX with auto-neg on

The 2.5G modes are 4 (HiSGMII PHY), 5 (HiSGMII MAC) and 6 (2500BASE-X): most of the hosts that support 2.5G work with the mode 6 and the port forced to 2500BASE-X, see the SFP standard page and the 2.5G compatibility list[3].

WARNING

A LAN_SDS_MODE not supported by the host makes the stick unreachable: the only way to restore it is the serial console.

GPON/OMCI settings ​

Getting/Setting ONU GPON Serial Number ​

sh
# /etc/scripts/flash get GPON_SN
GPON_SN=TMBB00000000
# /etc/scripts/flash set GPON_SN TMBB0A1B2C3D

Getting/Setting ONU GPON PLOAM password ​

Info

The PLOAM password is stored in ASCII format

sh
# /etc/scripts/flash get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=AAAAAAAAAA
# /etc/scripts/flash set GPON_PLOAM_PASSWD AAAAAAAAAA

Getting/Setting OMCI software version (ME 7) ​

sh
# /etc/scripts/flash get OMCI_SW_VER1
OMCI_SW_VER1=YOURFIRSTSWVER
# /etc/scripts/flash set OMCI_SW_VER1 YOURFIRSTSWVER
# /etc/scripts/flash get OMCI_SW_VER2
OMCI_SW_VER1=YOURSECONDSWVER
# /etc/scripts/flash set OMCI_SW_VER2 YOURSECONDSWVER

Getting/Setting OMCI hardware version (ME 256) ​

sh
# /etc/scripts/flash get HW_HWVER
HW_HWVER=V2.0
# /etc/scripts/flash set HW_HWVER MYHWVERSION

Getting/Setting OMCI vendor ID (ME 256) ​

sh
# /etc/scripts/flash get PON_VENDOR_ID  
PON_VENDOR_ID=ZTEG
# /etc/scripts/flash set PON_VENDOR_ID HWTC

Getting/Setting OMCI equipment ID (ME 257) ​

sh
# /etc/scripts/flash get GPON_ONU_MODEL
GPON_ONU_MODEL=DFP-34X-2C2
# /etc/scripts/flash set GPON_ONU_MODEL DFP-34X-XXX

Getting/Setting OMCI OLT Mode and Fake OMCI ​

Configure how ONT Stick handle OMCI from OLT:

sh
# /etc/scripts/flash get OMCI_OLT_MODE
OMCI_OLT_MODE=1
# /etc/scripts/flash set OMCI_OLT_MODE 2
ValueNoteOMCI Information
0Default ModeStock setting, some values cannot be changed
1Huawei OLT ModeHuawei MA5671a
2ZTE OLT ModeZTE
3Customized ModeCustom Software/Hardware Version, OMCC, etc...

Some vendors/wholesale providers/ISPs have explicit LAN Port Number provisioning or proprietary OMCI that the stick cannot understand, this will make the stick reply OK to whatever the OLT sends it via OMCI.

0 = Disable, 1 = Enable, Default is 0

sh
# /etc/scripts/flash get OMCI_FAKE_OK
OMCI_FAKE_OK=0
# /etc/scripts/flash set OMCI_FAKE_OK 1

Advanced settings ​

Setting management IP ​

sh
# /etc/scripts/flash get LAN_IP_ADDR
LAN_IP_ADDR=192.168.2.1
# /etc/scripts/flash set LAN_IP_ADDR 192.168.1.1

Getting/Setting the L2 Bridge MTU ​

Note

Settings given via diag are not permanent after reboot

Getting/Setting the MTU of the L2 bridge

sh
# diag switch get max-pkt-len port all 
Port Speed 
---------- 
0 1538 
2 2031 
# diag switch set max-pkt-len port all length 2000

Checking the currently active image ​

sh
# nv getenv sw_active
sw_active=1
# nv getenv sw_version0
sw_version0=V1_7_8_210412
# nv getenv sw_version1
sw_version1=V1_7_8_210412

Booting to a different image ​

The firmware upgrade always writes the inactive image, so it is possible to go back to the previous firmware[4]:

sh
# nv setenv sw_commit 0|1
# nv setenv sw_active 0|1
# reboot

Modifying the firmware ​

Warning

A wrong rootfs makes the image unbootable: always flash the inactive image, so that the stick can still boot the other one, and keep a backup of all the partitions.

Transferring files from/to the stick ​

Run md5sum on the source and on the destination to make sure that the file has not been corrupted.

Via SSH, from the stick to the PC and vice versa:

sh
ssh admin@192.168.2.1 "cat /dev/mtd5" > mtd5.bin
cat rootfs.new | ssh admin@192.168.2.1 "cat > /tmp/rootfs.new"

Via TFTP (a TFTP server must be running on the PC):

sh
# tftp <PC IP>
tftp> get rootfs.new
tftp> put <filename> <directory>
tftp> q

Via netcat (nc on the stick does not exit at the end of the transfer: stop it with CTRL+C)[5]:

sh
# on the stick
nc -l -p 12345 > /tmp/rootfs.new
# on the PC
nc 192.168.2.1 12345 < rootfs.new

Info

On Windows run the commands from cmd (not PowerShell) and replace cat with type.

Extracting and repacking the rootfs ​

The rootfs is a SquashFS (LZMA) image: on the stick it is in r0 (/dev/mtd5) for the image 0 and in r1 (/dev/mtd7) for the image 1, while the kernel is in k0 (/dev/mtd4) and k1 (/dev/mtd6).

Warning

Run both commands as root, otherwise the rootfs image might be damaged.

sh
# unsquashfs mtd5.bin
# mksquashfs squashfs-root rootfs.new -b 131072 -comp lzma -no-recovery

The RTL960x emulator runs the extracted firmware in QEMU (qemu-user-static) to modify and test it before flashing it: any file in its custom folder is copied over squashfs-root when leaving the chroot, and the custom startup scripts go in /etc/init.d/rc35.

Flashing a new rootfs ​

Check which image is running (nv getenv sw_active): flash mtd6/mtd7 if the image 0 is running, mtd4/mtd5 if the image 1 is running. The following commands flash a new rootfs to the image 1 and boot it:

sh
# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtd7
# nv setenv sw_version1 NEW_SOFTWARE_VERSION
# nv setenv sw_commit 1
# reboot

If cat fails with cat: write error: Invalid Argument, write the image to the block device instead:

sh
# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtdblock7

Repacking a firmware upgrade file ​

The firmware upgrade files of the ODM firmwares (e.g. V-SOL, T&W, ODI) are a tar containing the kernel (uImage), the rootfs, the fwu.sh upgrade script, the fwu_ver version file and the md5.txt checksums: after replacing the rootfs, update the checksums and repack it, then upload it from the Web GUI firmware upgrade page[5:1]:

sh
tar -xf firmware.tar
mv rootfs.new rootfs
md5sum fwu.sh rootfs uImage fwu_ver > md5.txt
tar -cvf ../firmware-mod.tar *

The Firmware_Mod folder of the RTL960x repository contains the community patches for the ODI DFP-34X-2C2, V-SOL V2801F and T&W TWCGPON657 (Bootstrap Web GUI, VLAN, speed and software version fixes).

Info

On this stick the files are usually transferred via TFTP (see Transferring files from/to the stick), and writing the rootfs to /dev/mtd7 may fail with Invalid Argument: in that case write it to the block device /dev/mtdblock7.

Enabling the Web UI ​

sh
# /bin/iptables -D INPUT -p tcp --dport 80 -j DROP
