Telnet control on too many devices

[glaahmet0]

We want to find out if telnet is turned on on our Cisco devices, but we have too many devices. How can we find out on which of our devices Telnet is turned on? :(( 

Tools we use: Solarwinds,Cisco prime, Cisco ISE

Run a port scan, solar wind has open port scanner, don’t think you can do it from prime.

Presume telnet is enabled and make plans to switch to more secure method, like SSH.
