When i download software for my 9300 switch for version 16.9.5, i have to decide between two images. the choices are:
1. CAT9300/9400/9500 Universal, or
2. CAT9300/9400/9500 UNIVERSAL W/O DTLS
what is DTLS? and how would i know if i need it or not?
Thanks,
Kevin

Usually DTLS image is not needed unless you want to configure TLS. See link for more info

KMeltonFLSA,
Images without DTLS cannot use any encryption services (e.g. MACsec). Originally these images were put in placed to sell to countries where US encryption standards are not allowed due to export restrictions or due to the receiving country's laws. if you are not selling to, or deploying in, one of these restricted countries, it is best to order the image with DTLS.
