Usage

Enable serial 

fw_setenv bootdelay 5
fw_setenv asc0 0
fw_setenv preboot

GPON ONU status

Get the operational status of the ONU 

onu ploamsg

Get 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 the ME_IN is the ME instance number

Getting/Setting Speed LAN Mode

Velue Speed
4 1 Gbps / SGMII
5 2.5 Gbps / HSGMII with auto-neg on

To enable the 2.5 Gbps / HSGMII with auto-neg on:

fw_setenv sgmii_mode 5

To remove the value (back to default):

fw_setenv sgmii_mode

To get the (H)SGMII Mode:

onu lanpsg 0

The link_status variable tells the current speed

GPON/OMCI settings

Enable parameters modification

This setting must be inserted in order to performs the others parameters modification

ritool set OperatorID 0000

Getting/Setting ONU GPON Serial Number

To check the current serial number:

onu gtcsng

To set the current serial number:

ritool set MfrID ABCD
ritool set G984Serial 012345678
ritool set YPSerialNum 012345678

Getting/Setting ONU GPON PLOAM password

To check the current password (the password field contains decimal values of ASCII characters):

onu gtccg

The value can be changed using the web interface.

Getting/Setting OMCI software version (ME 7)

Software verion must be changed by directly modifing firmware by using the patches which can be found in GitHub page of Nokia G-010-A and adding a folder 0001_swversion that contins a file patch.sh:

#!/bin/sh

set -e

ROOTFS=$1

echo "Changing to software version desidered"
sed -i s/3FE46398BGCB22/3FE45655BOCK99/g "$ROOTFS/usr/etc/buildinfo"

Where 3FE46398BGCB22 is the current software version and 3FE45655BOCK99 the software version desidered

Getting/Setting OMCI hardware version (ME 256) 

ritool set HardwareVersion 3FE47211EGAA
ritool set ICS 01

Getting/Setting OMCI equipment ID (ME 257)

This ONT is designed to save nokia equipment ID, specifically to put the equipment ID of a Nokia G-010G-Q we need:

ritool set CleiCode __________
ritool set Mnemonic G-010G-Q__

Where CleiCode is the prefix and Mnemonic the postfix.

Advanced settings

Transferring files to the stick 

# scp rootfs.bin root@192.168.1.10:/tmp/

Backup of all partition

Make a backup of all partitions, an easy way is:

  • On the stick run: 
    cat /proc/mtd
  • For each mtdX run in the lantiq shell: 
    cp /dev/mtdX /tmp

And in the computer shell:

scp ONTUSER@192.168.1.10:/tmp/mtdX ./

Checking the currently active image 

upgradestatus

Setting management MAC 

ritool set MACAddress 12:34:56:78:9A:BC

Setting management IP 

ifconfig eth0:1 192.168.1.10 netmask 255.255.255.0

Flashing a new rootfs via SSH

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

mtd write /tmp/rootfs.bin image1
update_env_flag 1
reboot

Disabling Dying Gasp 

uci set gpon.gtc.nDyingGaspEnable='0'; uci commit gpon

Rebooting the ONU 

reboot
