Swichport RSTP State

Raphael_L — Wed, 29 Mar 2023 18:39:38 GMT

Hi ,

Is it possible via any endpoint to get the RSTP state ?

I can see it from the dashboard :

( Which should be Discarding and not Blocking since this is based on RSTP and not 802.1D 🤔 )

The only way I was able to get something similar is via the port status Warnings : 'BPDU guard activated, STP discarding packets'

Thanks !

What device is connected to that port? Because rstp can fall back to stp

For purposes , I have looped my own switch. Eg : Port 2 into Port 3

Hmm i thought it might be a indication of that.

But apparently not 😛

A couple of calls return at least enabled state true/false, for instance https://developer.cisco.com/meraki/api-v1/#!get-device-switch-ports

...
    "rstpEnabled": true,
    "stpGuard": "disabled",
...

Might be worth trying it to see what you get, as the documentation often shows just a limited example of possible return data.

I don't know the answer.

This seems the closest - but it doesn't show that field in the example:

https://developer.cisco.com/meraki/api-v1/#!get-device-switch-ports-statuses

It does have an "Errors" and "Warnings" array - perhaps it might appear in there.

The other potential - ugly - way might be to retrieve the event log. Look for a log entry saying the port is blocked, that is not matched by a more recent entry saying that it is forwarding again.

It returns the actual configuration of the RSTP instead of the status 😞

But tbh I do think that Meraki is presenting the RSTP state on the dashboard at the wrong place. It is shadowing the configuration with the status :

So that's maybe why there are no endpoints that returns that info.

That is actually the most clever ( and only ) way that I have found so far !

I'm trapping these cases with the switch port statuses endpoint at the moment.

Warnings:[ 'BPDU guard activated, STP discarding packets']
