I am trying to setup and 2+0 Cross-polar link with 2 separate networks requiring segregation from each other but sharing the full capacity of the combined Radio Channels. Each network is to connected via fibre to an SFP port on 850C radios to each network’s own switches. These switches have been in service for sometime and currently only support 1Gbe SFP ports.
Reading through the User Guide I have a few queries regarding this setup.
Firstly, as per system release 12.5 (850C Overview, pages 853-855),port 3 (Eth2) is exclusively for dualband use (future release) and Port 5 (Eth 4) only supports 10G. Does this mean that Port 3(Eth2) is essentially unusable for general traffic? Does this mean that Port 5(Eth4) will not be able to be locked on to 1Gbe speeds or accept a 1Gbe SFP to connect to the older switches?
Secondly, if the physical connections can be established, does a LAG need to be setup combine each Ethernet service in order to push through the combined Radio channels? Also will this maintain the segregation of the networks or do further settings need to be used to prevent one network from being able to access the other?
Did yo get a chance to test 850C by connecting it to two separate network switches. Actually I was planning to test the scenario. Please let me know your feedback on the same.
We we able to deploy the segregated network to site and all is working well. Our setup was XPIC in the end. We managed to find, deep in the Cambium archives, a procedure to to set up VLANs on the services between each ethernet port and the MC-ABC service port.
We were able to test each service separately and they both had full use of the over-the-air throughput. We did not test each service whilst the other was passing traffic so we do not know if there was any unexpected overhead usage that restricted the total throughput.
The service has been operating for 6 months and each client is happy with the operation and capacity of the units. My concerns with the set-up is that management access can only be made through the management port. In our set up, this meant that only one of the users of the link had physical access the management port which opens up security risks for the other user. Thankfully, this was left to them to agree upon.
Here’s the link to the Cambium community post that has the instructions if you don’t already have it.
Let me know the results you get, would be interesting to see.
