Configuring SNMP
12-14 Configuring SNMP
Trap EngineID
To use traps instead of inform notifications, you would change the preceding configuration as
follows:
1. Use this command to specify trap notifications:
set snmp notify v3notify tag v3tag trap
2. Verify that the “createuser” entry in the NetSight Console SNMP trap configuration looks like
this:
createuser -e 0x800015f80300e06314d79c v3user MD5 md5passwd DES despasswd
When you are finished modifying the configuration, save the file and restart the SNMP Trap
Service using NetSight Services Manager.
Configuring an SNMP View
It is possible to include certain OIDs and exclude certain other OIDs within one SNMP MIB view.
You do this by stacking different set snmp view includes and excludes which specify a single view
name. This allows the user to view all of the “included” OID strings for their associated view
name, minus all of the “excluded” OID strings for their view name. If no such parameter is
specified, “included” is assumed.
Though it is possible to create and use multiple view names as desired, for demonstration
purposes it is simplest to modify the default view, since it is already being referenced by the
remainder of the SNMP command set.
The following example removes the default view specifications, and inserts one which permits
access to branch MIB 1.3.6.1.2.1 with the exception of branch interfaces 1.3.6.1.2.1.2.:
enterasys(su)->clear snmp view All 1
enterasys(su)->clear snmp view All 0.0
enterasys(su)->set snmp view viewname All subtree 1.3.6.1.2.1
enterasys(su)->set snmp view viewname All subtree 1.3.6.1.2.1.2 excluded
enterasys(su)->show snmp view
View Name = All
4. On the Enterasys 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 privacy
despasswd authentication md5
md5passwd
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:d2:32: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.
