The full TLS handshake: tls.record.content_type == 22

Client Hello:tls.handshake.type == 1

Server Hello: tls.handshake.type == 2

Client or Server Hello: tls.handshake.type == 2 or tls.handshake.type == 1

Only client Hello that match a server responding with TLSv1.2 or all client Hello messages?

Are tshark and grep an option?

There is a discussion in this bug about support for filtering on the Protocol column:

The dissector keeps track of the session version but I don't see where it's exposed to filter on.

ssl_session->session.version == TLSV1DOT2_VERSION
