Use this script:
SET SNMPUser = '.220.127.116.11.4.1.518.104.22.168.4.' + convert(varchar(5), Port+1)

You can do it that way or use ISQL/w.

IMMEDIATELY change the "Read Comm" AND the "R/W Comm" to something else
(think of them as passwords). The last thing you want is to have anyone out
there to have your SNMP read/write community name. Remember that messages
to this list are available on the web shortly after their posted, so if you
don't change those community names now, you put your maxes at a serious

You can leave the "Security" option set to "No". SNMP concurrency control
will work with it set to no.

Leave the RD and WR Mgr settings as 0.0.0.0. Actually, of all of the things
you displayed, you only need to change the two community names.

That, I don't remember. You can take a look in SQL Enterprise Manager,
though in 6.5, I don't remember where. Here's my stored procedure (from
CREATE PROCEDURE RadCheckOnlineSNMP @Username varchar(64) AS
FROM Servers s, ServerPorts sp
WHERE s.ServerID = sp.ServerID
SELECT NASIdentifier, 0, NULL, NULL, NULL

You're welcome. Get those community names changed!
Oh, once you change the community names, run this:
UPDATE Servers SET Community = 'abcxyz'
(changing abcxyz to whatever your new community name is)
