How to form a link in the lab setup for PTP 820 licensed (minimum configuration required)
Summary:
This document will explain the requirements and minimum configuration to form a PTP 820 link in a lab setup.
To establish a PTP 820 link in a lab setup we recommend to use bench setup kit. We can use the kits for bench testing, system staging before a radio is installed on a tower, troubleshooting in the lab, or setup for PTP 820 for classroom training.
For bench test kits part numbers refer the below community link.
Cause:
When we need to test the units in a lab before installing them in field so as to confirm the hardware status and see if the configuration is correct.
Solution:
The document explains the step by step configuration required to establish a link between two PTP 820 units in a lab setup.
Brief Summary of Steps:
- Connect both the PTP 820 units using the bench test kit.
- Power on the unit, connect the management port of radio to your laptop and change the Ethernet IP address of the laptop to 192.168.1.10 and the subnet mask to 255.255.255.0.
- Open a web browser and login into the web interface of the unit with 192.168.1.1(default IP)
- Select Planned Ethernet and Radio interfaces under Platform>Interfaces>Interface Manager.
- Configure Radio>radio parameters as per planning (TX frequency, RX frequency, TX level and set TX mute OFF, set TX level to low value as you are forming a link on a lab setup.
- Make sure TX/RX frequency is configured as per the part number of the radio (High radio should have high TX frequency and low RX frequency and the Low radio should have low TX frequency and high RX frequency) Link will not be formed if we have swapped the frequencies.
- If using both radio cores and using the same Tx and Rx frequencies on both cores, please set XPIC as enabled under Radio>Groups>XPIC.
- Configure services P2P and MNG with two service points (Radio and Ethernet) under Ethernet> services. Assign a VLAN to the MGT Radio service point.
- Make sure the MRMC script is the same and as per planning on both sides of the link under Radio> MRMC>symmetrical scripts>FCC/ETSI (as per the region).
STEPS to configure the minimum configuration to form a link between two PTP 820 radios in a lab setup.
Power ON the unit.
Power ON the PTP 820 unit with the cambium recommended power supply. If using a third-party power supply, you may experience continuous reboot issues due to different power consumption ratings.
Once the unit is powered ON successfully, please connect the management port of the PTP 820 radio to your laptop with the Ethernet LAN cable. Once the laptop detects the Ethernet connection, open the network and sharing center to change the IP address of the laptop. (Refer below screen shot).
Click on change adapter options/settings.
Select Ethernet/Local network option to open Ethernet status page.
Click on properties
Select Internet protocol version 4(TCP/IPv4) and click on properties
Default IP Address of PTP 820 is 192.168.1.1 so you can set the laptop IP address to 192.168.1.10 and subnet mask as 255.255.255.0 and apply.
Once this is done, enter the default IP address (192.168.1.1) of PTP 820 on web browser
Below is the login window which will appear after entering the default IP address on web browser.
Default user name of PTP 820 unit is “admin” and password is “admin”
After entering user name and password below window appears. (Unit Summary)
PTP 820S (Single Core) - Interface Manager.
Click on Platform>Interfaces>Interface Manager. PTP 820S (Single core) has 3 Ethernet interfaces, 1 Radio port and 1 Management port.
Admin state of one radio port and the required Ethernet port (At least one) should be up. Admin status of unused ports can be set as down.
Management port status will be up by default.
PTP 820C (Dual Core) - Interface Manager
PTP 820C is a dual core radio hence we can use either the single radio or both radio cores. If we use single core (H or V) then it behaves similar to the PTP 820S radio (1+0)
If we use both radio ports (Horizontal + vertical) then it behaves as dual core. (2+0)
Select the required radio cores, either one or both, and the Ethernet port and set the admin status as up. Admin status of unused ports can be set as down.
PTP 820G – Interface Manager.
Similarly, in PTP 820 G you can select the required radio and Ethernet interfaces and set the admin status as up. Admin status of unused ports can be set as down.
PTP 820S Radio Parameters:
Click on Radio>Radio parameters.
Under Radio parameters enter the planned TX frequency, RX frequency, TX level (set TX level to low value as you are forming a link on a lab setup), set TX Mute as Unmute/OFF and Apply.
PTP 820 CG Radio Parameters:
Click on Radio>Radio parameters.
Under Radio parameters you will see two radio ports (Radio slot 2 port 1 and Radio slot 2 port 2). Select the one you need to use and click on Edit.
Enter the planned TX frequency, RX frequency, TX level (set TX level to low value as you are forming a link on a lab setup), set TX Mute as Unmute/OFF and Apply.
If you have planned to use both the radio ports then select the other radio port and click on EDIT to  Enter the planned TX frequency, RX frequency, TX level (set TX level to low value as you are forming a link on a lab setup), set TX Mute as OFF and Apply.
Also, if we are using both radio cores in PTP 820C or G and the same Tx and Rx frequencies on each core we need to enable XPIC.
Ethernet Services for PTP 820 S-C-G
Click on Ethernet>Services
Under services we have a default MNG service. We need to add P2P service for data traffic to flow across the RF link. Click on ADD.
Adding P2P service
After clicking on ADD, a new window pops up. Select service type, ECC ID and EVC description as P2P, click on Apply.
Once the P2P service is added it will appear as below. Now we need to add service points under P2P service. Select P2P service and click on service points.
Click on Add to add service points.
Adding first P2P service point for PTP 820S:
After clicking on ADD below window appears.
Select Pre defined options as “option #8(PIPE,dot1q)”
Enter service point name as Radio. And select Interface location as “Radio: Slot 2, Port1”
Adding Second P2P service point for PTP 820S
Now again we need to click on add, After clicking on ADD below window appears.
Select Pre defined options as “option #8(PIPE,dot1q)”
Enter service point name as Ethernet. And select Interface location as “Ethernet slot 1 port 1”
Once both the service points are added below window appears
MNG Service points: (In Band management)
Now we need to add service points under MNG service, select MNG service and click on service points.
Click on Add to add service points.
Adding first MNG service point for PTP 820S:
After clicking on ADD below window appears. Select Pre-defined options as Option #1 (MNG, dot 1q). Enter service point name as Radio and the Interface location as radio: Sot 2 port 1. If you want to configure any VLAN select it under C-VLAN encapsulation otherwise keep it as untagged. Adding a C-VLAN to the MGT Radio service point is recommended. This VLAN will only be used over the radio interface.
Adding Second MNG service point for PTP 820S
Now again we need to click on add, After clicking on ADD below window appears.
Select Pre defined options as Option #1 (MNG, dot 1q). Enter service point name as Ethernet and the Interface location as Ethernet Slot 2 port 1.
After adding both the service points under MNG below window appears.
Now we have configured both the services P2P (For data traffic) and MNG (For management).
Make sure the MRMC script is the same and as per planning on both sides of the link under Radio> MRMC>symmetrical scripts>FCC/ETSI (as per the region).
Once the above configuration is complete, we will be able to form a link between two PTP 820 units in a lab setup.
