Hardware Specifications

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:

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

diag gpon get onu-state

Querying a particular OMCI ME

# omcicli mib get MIB_IDX

Getting/Setting Speed LAN Mode

To change the link mode use this command:

# /etc/scripts/flash get LAN_SDS_MODE
LAN_SDS_MODE=0
# /etc/scripts/flash set LAN_SDS_MODE 1

GPON/OMCI settings

Getting/Setting ONU GPON Serial Number

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

Getting/Setting ONU GPON PLOAM password

# /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)

# /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)

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

Getting/Setting OMCI vendor ID (ME 256)

# /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)

# /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:

# /etc/scripts/flash get OMCI_OLT_MODE
OMCI_OLT_MODE=1
# /etc/scripts/flash set OMCI_OLT_MODE 2

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

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

Advanced settings

Setting management IP

# /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

Getting/Setting the MTU of the L2 bridge

# 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

# 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

# nv setenv sw_commit 0|1
# reboot

Enabling the Web UI

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

Transfering files from/to the stick

Works with binary files too, just run md5sum on source and destination to make sure you are not corrupting anything… From the stick to the PC:

# tftp <IP>
tftp> put <filename> <directory>
tftp> q

From the PC to the stick:

# tftp <IP>
tftp> get <filename>
tftp> q

Extracting and repacking the rootfs

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

Flashing a new rootfs

Flash mtd4/5 if you are on image1, mtd6/7 if you are on image0.

The following commands are used to flash a new rootfs to image1 and then boot to it

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

If you get this error on cat command

# cat /tmp/rootfs.new > /dev/mtd7
cat: write error: Invalid Argument

Use this proceudre instead to write firmware back to mtd:

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

Then make new firmware bootable

# nv setenv sw_version1 NEW_SOFTWARE_VERSION
# nv setenv sw_commit 1
# reboot
