Setting SSHD to use protocol 2 instead of 1

I have sshd running on a few boxes (version is 3.4) and would like to make sure they are accepting only protocol 2 instead of 1. Does anyone know how i can force my sshd to accept only protocol 2 connections and not 1?

In /etc/ssh/ssh_config, change this

Protocol 2,1
to this

Protocol 2
(and then restart sshd)
