S3300 Smart Managed Pro Switch
Use SNMPv3
The switch software supports the configuration of SNMP groups and users that can manage
traps that the SNMP agent generates.
The switch uses both standard public MIBs for standard functionality and private MIBs that
support additional switch functionality
. All private MIBs begin with a hyphen (-) prefix. The
main object for interface configuration is in -SWITCHING-MIB, which is a private MIB. Some
interface configurations also involve objects in the public MIB, IF-MIB.
SNMP is enabled by default. The System Information screen, which is the screen that
d
isplays after a successful login, displays the information you need to configure an SNMP
manager to access the switch. To configure information for SNMPv1 or SNMPv2, see SNMP
on page 95.
Any user can connect to the switch using the SNMPv3 proto
col, but for authentication and
encryption, the switch supports only one user which is admin; therefore there is only one
profile that can be created or modified.
To configure authentication and encryption settings for the SNMPv3 admin profile by
using the web interface:
1. Select Sy
stem > SNMP > SNMPv3 > User Configuration. The User Configuration
screen displays.
Figure 15. SNMPv3 User Configuration
The SNMPv3 Access Mode is a read-only field that shows the access privileges for the
user account. The admin account always has Read/Write access, and all other accounts
have Read Only access.
2. T
o enable authentication, select an Authentication Protocol option.
If the authentication protocol is MD5 or SHA,
the user login password will be used as
SNMPv3 authentication password. To configure the login password, see Change
Password on p
age 241.
3. T
o enable encryption:
a. I
n the Encryption Protocol field, select the DES option to encrypt SNMPv3 packets
using the DES encryption protocol.
b. I
n the Encryption Key field, enter an encryption code of eight or more alphanumeric
characters.
4. Click the Ap
ply button.
