Cambium Model Issues

[tmcdon89]

I'm getting generic fails when trying to connect to cambium PMP models using the built in cambium.rb model.

Its trying three times then moving on. Using oxidized -d doesn't reveal much.

I'm happy to share what Info I can, but I'm not sure where to start on posting. I'm seeing the same results as millenium7 in issue: https://github.com/ytti/oxidized/issues/1287

Seeing the same. I'm running 0.27.0 My debug logs look like this:

A tcpdump confirms that NO outbound packets are being sent to the target (HTTP, SSH, Telnet, or otherwise). DNS resolution confirmed working.

Debug log does not make any reference to lib/oxidized/input/http.rb (whereas for i.e. juniper devices, there are lines like "... lib/oxidized/input/ssh.rb: Connecting to ...")

My input stanza looks like this:

input: debug: true http: debug: true

my models stanza looks like this:

models: junos: username: password: cambium: username: password:

I also noticed that https://www.rubydoc.info/gems/oxidized/Oxidized/Input does not list HTTP as an input method (though i.e. TFTP and FTP are listed, along side the standard SSH and Telnet)

I have all of the dependencies described in https://rubygems.org/gems/oxidized . I see that it lists net-ssh and net-telnet as required gems. Why no net-http gem?

[martydingo]

Bumping this as Cambium is within our ecosystem, this only supports 450i's and there's other devices too.

On this issue though, I'm not seeing any configurations being pulled on 450i's. Can we please clarify the naming convention too, since Cambium has ePMP3000's which aren't supported by this model, and it's misleading until you find the small note in the docs section.

[ytti]

In reality we support specific NOS, not vendor or model. So the models should be named based on NOS. So perhaps open support case to vendor and ask what do they call the different NOS they have.

[martydingo]

@ytti Well, this model should be named along the lines of CambiumCanopy, as Canopy is the 'NOS' in use on that, but just Canopy isn't very clear. As the other models are currently not supported it's not so much a bother, but then the ePMP series of NOS would then be 'Cambium-ePMP' and so forth.

[ytti]

If model does not work, it usually implies it's different NOS. You're proposing to call them VendorModel, which is not what we want to do, several models can use same NOS.

[martydingo]

@ytti That makes sense. They name the software 'Canopy', which runs on PMP Series, which includes the 450 series, you can see this here. The others do not seem to be clearly named, so I'll shoot them an e-mail later on.

In any case I'm derailing this issue, so I'll create a new issue for the naming convention when I have all the information. Configuration retrieval should be pretty easy on their other radios comparatively to Canopy, so once the naming standards are sorted I can look at seeing how difficult it would be to implement.

[typecookie]

along these lines i have a bash script that pulls configs from pmp1000 via SNMP is there a possibility it might be convertible to ruby and integrated???

I'm a script monkey and all my code is haky

[martydingo]

I've written the code already.

Save the following as /var/lib/gems/2.5.0/gems/oxidized-0.28.0/lib/oxidized/model/cambiumepmp.rb (Please double check the oxidized-0.28.0 folder is named correctly as the versioning may be different on your end)

 class CambiumePMP < Oxidized::Model
  # Cambium ePMP Radios

  # prompt /\(.*\)>/
  prompt /.*>/

  cmd :all do |cfg|
    cfg.cut_both
  end

  pre do
    cmd 'config show json'
  end

  cfg :ssh do
    pre_logout 'exit'
  end
end

Use the CambiumePMP as the model / device type / NOS in your configuration/inventory file.

[typecookie]

you are a champion dingo thanks for this

[NoifP]

Thanks Marty! That's awesome!

[NoifP]

Thanks @martydingo; it's working great!

Hi @martydingo I flow your instruction to add a new feature to scan the Cambium epmp 3000 AP series, but, dosen't works for me.

According to the log, the model name is "epmp", so I renamed the file cambiumepmp.rb to epmp.rb, but when I run oxidized, I get the following error: 1: from /var/lib/gems/2.5.0/gems/oxidized-0.28.0/lib/oxidized/manager.rb:60:in 'loader' /var/lib/gems/2.5.0/gems/oxidized-0.28.0/lib/oxidized/manager.rb:17:in 'load': undefined method 'new' for nil:NilClass (NoMethodError) My config file:

Any idea? Thanks in advance.

[martydingo]

I'm pretty sure you have to use cambiumepmp as the model. Be aware this issue is about 450i support. From #2081

CambiumCanopy (i.e. for 450-series PTP and PMP devices - aka "Canopy" NOS) CambiumEPMP (for EPMP3000-series devices, including low-end PTP devices - aka "Cambium Networks" NOS) CambiumCeraOS (for Ceragon-derived products - aka CeraOS NOS)

[CharlyBote]

Thanks for your answer @martydingo I attach the debbug for oxideized for epmp model name

It needs to be configured as cambiumepmp, not epmp. You need to follow the instructions closely, and don't deviate with file names. Potentially an issue within Oxidized, but I'm unsure as I don't work at the place I required this and Oxidized for. It's also potentially a point that inside the ruby script, it's referenced as cambiumepmp, and Oxidizied is now looking for 'epmp'.

I'd remove all the things you've done to add epmp support, and start by placing the cambiumepmp.rb file in the correct location. configuring it without making any modifications to any files except for configurations, and see what output you arrive at.

I was using this on the same version are you are on currently, so I don't foresee any issues on that front.
