[Bro] Help with bro scripting exercise question

[craig bowser]

Hello all, trying to learn bro scripting.  I am working through the
exercises from the 2011 workshop and I'm getting an error.

I'm on this page:
https://www.bro.org/bro-workshop-2011/exercises/notices/index.html

I'm on Pt3 More Advanced Policy Notice running this script:

const watched_servers: set[addr] = {
172.16.238.136,
172.16.238.168,
} &redef;

redef Notice::policy += {
	[$action = Notice::ACTION_ALARM,
	 $pred(n: Notice::Info) =
		{
		return n$note == SSH::Login && n$id$resp_h in watched_servers;
		}
	]
};


And I'm getting an error that says

#bro -r ssh.pcap local advancebro.bro
error in ./advancebro.bro, line 10: unknown identifier SSH::Login, at
or near "SSH::Login"


Is the SSH::Login no longer a valid function?

Thanks.
