4. On the N-Series switch, define the same user as
in the above example (v3user) with this
EngineID and with the same Auth/Priv
passwords you used previously.
set snmp user v3user remote
800007e5804f190000d232aa40
authentication md5 md5passwd privacy
despasswd
Note: You can omit the 0x from the
EngineID. You can also use the colon
notation like this:
80:00:07:e5:80:4f:19:00:00:d
2:32:aa:40
5. Navigate to and display the user configuration
on the management station. (This assumes that
you have already created the user in Netsight
Console, so you will only need to add it to the
configuration file of the trap daemon.)
C:\Program Files\Enterasys
Networks\NetSight
Console\Bin\snmptrapd.conf
6. Using any plain text editor, add this line to the
configuration file.
createuser v3user MD5 md5passwd DES
despasswd
Note: When installed on a Unix platform, the NetSight server must be manually restarted.
