Note The following wiki is only compatible with version 5 or later!

Flashing the firmware

Flash the firmware image to image0 or image1 via SSH or via TTL serial as usual.

After flashing, it is absolutely necessary to connect to the SFP via telnet using the IP 192.168.1.10:

telnet 192.168.1.10

Once connected via telnet to the SFP, execute the following commands. Then wait a few minutes until the end of the automatic procedure:

firstboot
reboot

Performing the procedure described above is necessary after each flash of this firmware, otherwise the SFP will not work!


Username	root
Password	root
IP address	192.168.1.10
Telnet	Always available
TTL Serial	Always available
SSH	Only after the first configuration (firstboot)
Web	NO

GPON ONU status

Getting the operational status of the ONU

onu ploam_state_get

Getting optical laser status

otop -g s

Getting information of the OLT vendor

omci_pipe.sh meg 131 0

Querying a particular OMCI ME

omci_pipe.sh meg MIB_IDX ME_IN

Where MIB_IDX is the MIB ID and ME_IN is the ME instance number.

Getting VLAN table rule

gtop -g "GPE VLAN rule"

Getting GEM port status table

gtop -g e

Getting/Setting Speed LAN Mode

To get the LAN Mode:

onu lan_port_status_get 0

The link_status variable tells the current speed:

Value (for `sgmii_mode` and `link_status`)	Speed
3	1 Gbps / SGMII with auto-neg on
4	1 Gbps / SGMII with auto-neg off
5	2.5 Gbps / HSGMII with auto-neg on

To change the default lan mode value you can use fw_setenv sgmii_mode. The firmware is already set to 2.5G auto-negotiation, you shouldn’t touch it.

GPON/OMCI settings

Setting ONU GPON Serial Number

fw_setenv onu_serial "YOUR_SERIAL_ASCII"

Setting ONU GPON PLOAM password

fw_setenv onu_ploam "YOUR_PLOAM_ASCII"

Note If your ploam is in HEX convert it to ASCII, any non-printable characters write them in HEX with a slash in front, such as \7F. If the PLOAM is less than 10 bytes (one printable character counts as one byte, \7F also counts as one byte) add \00 to the end to get to 10 bytes.

Setting ONU GPON LOID

fw_setenv onu_loid "YOUR_LOID"

Setting ONU GPON LOID password

fw_setenv onu_loid_password "YOUR_LOID_PASSWORD"

Setting OMCI vendor ID (ME 256)

fw_setenv omci_vendor_id "YOUR_VENDOR_ID"

Setting OMCI equipment ID (ME 257)

fw_setenv omci_equip_id "YOUR_EQUIP_ID"

Setting OMCI hardware version (ME 256)

fw_setenv omci_hw_ver "YOUR_HW_VER"

Setting OMCI software version (ME 7)

fw_setenv image0_version "YOUR_SW_VERSION_0"
fw_setenv image1_version "YOUR_SW_VERSION_1"

Advanced settings

Note Changing these is normally not necessary and not changing them is a good idea

Setting custom OMCI MIB file

Copy the MIB file to /etc/mibs, then run this command:

fw_setenv mib_file_custom "YOUR_MIB_FILENAME"

Setting management IP

fw_setenv ipaddr www.xxx.yyy.zzz

Restore SFP to default config
