I am using the Meraki Switch Configuration Wizard to try and add my Meraki switches to XI but I just get the following error message:
warning
No ports were detected on the m_switch
Possible reasons for this include...
The m_switch is currently down.
The m_switch does not exist at the address you specified.
SNMP support on the m_switch is disabled.

I've tried both the API and manual methods and get the same error. The API method successfully pulls back all of my Meraki switches. I ran the suggested command that came with the error and received the following results:

Any suggestions?

Hello macwjp,

Looking at the output it appears there is an issue decrypting the data from snmp which could explain why no ports are being found. One of the thoughts after a little research could be the privprotocol for most meraki switches is aes128 so that could be causing issues at least with the cfgmaker command. Along with that I would double check all the inputs on your end are right and the meraki switch is properly set up for snmp. Before using the wizard again I would try getting a successful output via the "snmpwalk" command on the CLI to ensure that you're properly configuring everything on the switches end. I would recommend reaching out to support if you haven't already https://support.nagios.com/.
