# General Settings and Useful Commands
## Useful files
- `/var/config/lastgood.xml` - Contains the user portion of the configuration
{% if include.lastgoodHs %}
- `/var/config/lastgood-hs.xml` - Contains the "hardware" configuration (which _should not_ be changed)
{% endif %}
- `/tmp/omcilog` - OMCI messages logs (must be enabeled, see below)
## Useful binaries
- `{{ include.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 `{{ include.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
## Getting/Setting the ONT's S/N
```sh
# {{ include.flash }} get GPON_SN
GPON_SN=TMBB00000000
# {{ include.flash }} set GPON_SN TMBB0A1B2C3D
```
## Getting/Setting the ONT's PLOAM password
{% if include.ploam == 'asciiAndHex' %}
{% include alert.html content="The ploam can be saved in either ASCII or HEX format, without any 0x or separators" alert="Note" icon="svg-info" color="blue" %}
```sh
# {{ include.flash }} get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=AAAAAAAAAA
# {{ include.flash }} set GPON_PLOAM_PASSWD AAAAAAAAAA
# {{ include.flash }} set GPON_PLOAM_PASSWD 41414141414141414141
```
{% elsif include.ploam == 'hex' %}
{% include alert.html content="The PLOAM password is stored in HEX format, without any 0x or separators" alert="Note" icon="svg-info" color="blue" %}

```sh
# {{ include.flash }} get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=AAAAAAAAAA
# {{ include.flash }} set GPON_PLOAM_PASSWD AAAAAAAAAA
```
{% endif %}
## 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
```sh
# nv setenv sw_commit 0|1
# reboot
```
## Getting/Setting the ONT Vendor ID
{% include alert.html content="This may need the OMCI_OLT_MODE value to be set to 3 to work" alert="Note" icon="svg-info" color="blue" %}
```sh
# flash get PON_VENDOR_ID
PON_VENDOR_ID=ZTEG
# flash set PON_VENDOR_ID HWTC
```
## Getting/Settng the ONT Custom software version
{% assign customSwVersionAlert = include.customSwVersionAlert | default: "This needs the OMCI_OLT_MODE value to be set to 3" %}
{% include alert.html content=customSwVersionAlert alert="Note" icon="svg-info" color="blue" %}
```sh
# nv setenv sw_custom_version0 YOURFIRSTSWVER
# nv setenv sw_custom_version1 YOURSECONDSWVER
```
## Getting/Setting a custom HW Version
{% include alert.html content="This may need the OMCI_OLT_MODE value to be set to 3 to work" alert="Note" icon="svg-info" color="blue" %}
```sh
# {{ include.flash }} get HW_HWVER
HW_HWVER=V2.0
# {{ include.flash }} set HW_HWVER MYHWVERSION
```
## Getting/Setting a custom ONT Equipment ID
{% include alert.html content="This may need the OMCI_OLT_MODE value to be set to 3 to work" alert="Note" icon="svg-info" color="blue" %}
```sh
# {{ include.flash }} get GPON_ONU_MODEL
GPON_ONU_MODEL=DFP-34X-2C2
# {{ include.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
# {{ include.flash }} get OMCI_OLT_MODE
OMCI_OLT_MODE=1
# {{ include.flash }} set OMCI_OLT_MODE 2
```
| Value | Note | OMCI Information |
| ----- | --------------- | ---------------------------------------------- |
| 0 | Default Mode | Stock, some value are cannot be change |
| 1 | Huawei OLT Mode | Huawei MA5671a |
| 2 | ZTE OLT Mode | ZTE |
| 3 | Customized Mode | Custom Software/Hardware Version, OMCC, etc... |
Some Fiber Vendor/Wholesale/ISP have explicit LAN Port Number provisioning or proprietary OMCI that ONT Stick cant not understand, this will make ONT Stick reply OK whatever OMCI OLT throw at.
`0` = Disable, `1` = Enable, Default is 0
```sh
# {{ include.flash }} get OMCI_FAKE_OK
OMCI_FAKE_OK=0
# {{ include.flash }} set OMCI_FAKE_OK 1
