Here is an example of searching ARP records for mac address:Continue reading “How to view ARP and MAC addresses on Cisco”
Today it was necessary to go into the BIOS on the Lenovo IdeaPad 110-15IBR laptop (80T7), but when you press all the keys that are usually used to enter the BIOS, the laptop did not respond and the system continued to boot.
As it turned out, in the BIOS of this Lenovo laptop model, the HotKey Mode function is activated as standard and the functional keys are activated instead of the F1-F12 keys.
Therefore, to enter the BIOS, it is necessary to press two Fn and F2 keys simultaneously, if HotKey Mode is disabled, then simply F2.
On the test I’ll take the H805GPFD board with 16 GPON ports and install it in OLT Huawei SmartAX MA5683T without shutting it down.
After inserting on the board, the RUN / ALM indicator flashed red and literally a minute later green.
Optionally, before inserting the board, you can turn on alarm output and then turn off:
alarm output all undo alarm output all
When the board is already installed, in the configuration mode, confirm it:
board confirm 0/3
And enable ONT detection on ports:
interface gpon 0/3 port 0 ont-auto-find enable port 1 ont-auto-find enable port 2 ont-auto-find enable port 3 ont-auto-find enable port 4 ont-auto-find enable port 5 ont-auto-find enable port 6 ont-auto-find enable port 7 ont-auto-find enable port 8 ont-auto-find enable port 9 ont-auto-find enable port 10 ont-auto-find enable port 11 ont-auto-find enable port 12 ont-auto-find enable port 13 ont-auto-find enable port 14 ont-auto-find enable port 15 ont-auto-find enable quit
Let’s look at the information about the board:
display board 0/3 display cpu 0/3
Exit the configuration mode and save the current configuration:
If you are using the U2000, then by clicking on the OLT, select “Synchronize NE Configuration Data”.
In the old version of U2000 R009 noticed that in the main window a question mark is displayed instead of the port of the board, in this case it is necessary to update U2000 or for example add ONT through GPON – GPON Management – GPON UNI Port tab – select port – ONU Info tab – Auto Discover ONUs.
See my video on installing H805GPFD in Huawei SmartAX MA5683T:
On an example I will use ASUS RT-G32 Rev.C1 router with firmware version 188.8.131.52.Continue reading “Firmware Update for ASUS RT-G32 Router”
UPnP (Universal Plug and Play) – universal automatic configuration of network devices, automatically opens ports for p2p applications, games, etc.
In the Winbox settings you can find the “IP” – “UPnP“.
To enable it, check Enabled.
Now you need to specify interfaces, click “Interfaces” and “Add New“.
We’ll add an external WAN port, usually ether1-gateway.
Add an internal port or bridge, such as a bridge.
This completes the configuration.
I’ll give an example of how this will look through the console:
ip upnp set enabled=yes ip upnp interfaces add interface=ether1-gateway type=external ip upnp interfaces add interface=bridge type=internal
On the test, I will update the SSD firmware of the Kingston SV300S37A 120Gb drive.
1) Download the official utility Kingston SSD Manager with firmware upgrade
2) Run the downloaded utility and if there is a firmware newer, the “Update to firmware …” button will be displayed, and click it to start the update process, which will last a few seconds.
Done, watch the video as I did:
