OLT tools: cards, PON ports, uplink, VLANs, profiles, CLI and save
Every OLT you added has its own page. To open it, go to Settings, then OLTs, and click View on the row of the OLT. You can also click the OLT name in "Your OLT fleet" on the Overview.
Tabs and actions depend on the manufacturer and model. Read-only preview drivers hide configuration controls. See supported OLTs.
If the panel cannot read the OLT, a red box at the top of the page says "SmartOLT cannot read this OLT" with the error and a checklist of the connection steps. Read Connection troubleshooting to fix it.
OLT details
This is the first tab. A table lists the settings and the last values read from the OLT: Name, OLT IP, Connection (direct or VPN tunnel), the Telnet port and username, SNMP monitoring, OLT hardware version, OLT software version, the signal warning and critical levels (-25 and -27 dBm), Last read, Configuration saved and the number of ONUs online, authorized and waiting. The OLT password is never shown. Beside the table you see a picture of the OLT with its Uptime and Temperature.
For an OLT connected through the VPN, a panel under the table shows whether the tunnel is connected and the commands to paste into your MikroTik. See Connect with OpenVPN on MikroTik.
The buttons on this tab
| Button | What it does |
|---|---|
| Edit OLT settings | Opens the form with the name, connection, Telnet login and SNMP settings. Saving the form logs in to the OLT and reads it at once. See Add an OLT. |
| Refresh | Reads the OLT now, without waiting for the next 5 minute read. It reads the boards, profiles, VLANs, every ONU with its status and signal, and the waiting ONUs. On a big OLT this takes up to a minute. You then see a line such as "Main OLT read: 412 ONUs, 398 online." |
| See history | Opens the activity log with only the actions on this OLT. See Tickets and task history. |
| CLI | Opens the CLI tab. |
| Save config | Opens the "Save OLT configuration" box. See Save below. |
| Unconfigured | Opens the list of ONUs waiting for authorization on this OLT. See Authorize an ONU. |
OLT cards
One row for each board in the OLT: Slot, Card (the board name), Status, Role (GPON service board, Control board, or Uplink or power), the number of PON ports and ONUs online out of the ONUs on that board. A status in green is normal. A status in red needs your attention. Click Refresh OLT cards info to read the OLT again, for example after you insert a new board.
PON ports
One row for each PON port.
| Column | What it shows |
|---|---|
| PON port | Frame/slot/port, for example 0/1/3. |
| ONUs and Online | Authorized ONUs on the port, and how many are online. |
| Load | The ONUs on the port out of 128. The bar turns orange from 70% and red from 90%. |
| Power fail and LOS | ONUs on the port that are down for each reason. Click a number to list those ONUs. |
| Average signal and Weakest | The average and the lowest light level received by the ONUs on the port. |
On each row with ONUs, ONUs opens the Configured list for that port and the graph button opens its graph on the Graphs page. Above the table, Refresh PON ports info reads the OLT again and Unconfigured ONUs opens the waiting list.
Uplink
The Uplink tab shows the Ethernet interfaces of the OLT and their traffic. This tab needs SNMP. The rest of the panel works without it.
- Configure a read-only SNMPv2c community on the OLT.
- Click SNMP settings, tick Enable read-only SNMPv2c, enter the community and the UDP port, and save.
- For an OLT behind the VPN, copy the MikroTik commands from the OLT details tab again and paste them into the router. The new commands also carry SNMP.
- Back on the Uplink tab, click Test SNMP / refresh counters. You should see "SNMP read completed."
The table then lists each interface with Admin and Link state, Capacity, Receive Mbps and Transmit Mbps. A rate needs two successful reads and is the average between them. Automatic reads run every five minutes, and each interface gets a graph of the last 24 hours. A restart of the OLT or a missing counter leaves a gap. A failed SNMP read does not mean that the Telnet connection is down. Run display command opens the CLI tab.
VLANs
This tab lists the VLANs read from the OLT: VLAN-ID, Type, Description and the number of ONUs in the panel that use it. Click the number to list those ONUs. VLAN 1 is not listed.
- Click Add VLAN.
- Enter the VLAN-ID, from 2 to 4094, and a short Description.
- Click Add VLAN. The panel creates the VLAN on the OLT.
A VLAN you add here is not tagged on the uplink ports of the OLT. Tag it on the uplink interface yourself, or traffic in this VLAN will not reach your router.
Delete removes a VLAN from the OLT after you confirm. The panel refuses to delete a VLAN that ONUs still use. Move those ONUs to another VLAN first.
Profiles
This tab is for reading only. It shows what exists on the OLT:
- Line profiles: ID, name, the number of bindings on the OLT and the number of ONUs in the panel that use the profile.
- Service profiles: ID, name and bindings on the OLT.
- Speed tables (traffic tables): index, CIR and PIR.
Click Scan OLT profiles after you create a profile on the OLT by hand, so the panel knows about it. The speeds you offer to customers are set in the panel. See Speed profiles and ONU types.
CLI
The CLI tab lets you ask the OLT a question without opening a Telnet client.
- Type a command in Display command, for example
display board 0. - Click Run.
- Read the answer in the box under the form. Click Copy to copy it.
What the CLI allows: only commands that start with display, on one line. Any other command is refused with the message "Only display commands can be run here". So nothing on the OLT can change by accident from this tab. Changes are made with the other pages of the panel. Each command you run is written to the activity log.
Quick checks
The Quick checks box has ready commands. Fill in Frame, Board, Port and ONU when the check needs them, then click the check.
| Check | Needs |
|---|---|
| Software version, Uptime, Boards, Unauthorized ONUs (autofind), Speed tables, VLANs, Line profiles, Service profiles | Nothing |
| One board | Frame, Board |
| ONUs on a PON port, Optical levels on a PON port, Service ports of a PON port | Frame, Board, Port |
| One ONU, Running config of one ONU | Frame, Board, Port, ONU |
Save: keep the configuration on the OLT
When you authorize or change an ONU, the OLT applies the change to its running configuration. The running configuration is lost when the OLT restarts, unless it was saved. Save writes what is running on the OLT to the memory of the OLT. ONUs authorized or changed since the last save are then still there after a restart.
- Click Save in the side menu, or Save config on the OLT details tab. The "Save OLT configuration" box opens.
- Choose one OLT, or All OLTs. Beside each OLT you see how long ago it was last saved from the panel.
- Click Save and wait. A save can take some time on a big OLT.
- You should see "Configuration saved on" with the name of the OLT. If an OLT could not be saved, a red message gives its name and the reason.
If the OLT restarts or loses power before you save, the ONUs you authorized since the last save are gone from the OLT and those customers have no service. Save after each group of authorizations or changes.
The Configuration saved row on the OLT details tab shows the last save made from the panel. Each save is also listed in the Task history. Save is not a backup: it keeps the configuration inside the OLT. To keep a copy outside the OLT as well, use Configuration backups.
