GS748T Smart Switch 
The GS748T Smart Switch uses both standard public MIBs for standard functionality and 
private MIBs that support additional switch functionality. All private MIBs begin with a “-” 
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  Management  System Information Web page, 
which is the page that displays after a successful login, displays the information you need to 
configure an SNMP manager to access the switch. 
Any user can connect to the switch using the SNMPv3 protocol, 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. Navigate to the System  SNMP  SNMPv3  User Configuration page.
2. To enable authentication, select an Authentication Protocol option, which is either MD5 or 
SHA.
3. To enable encryption, select the DES option in the Encryption Protocol field. Then, enter 
an encryption code of eight or more alphanumeric characters in the Encryption Key field.
4. Click Apply.
To access configuration information for SNMPv1 or SNMPv2, click System  SNMP  
SNMPv1/v2 and click the page that contains the information to configure.
