Configuring SNMP
The PT-7728 supports SNMP V1, V2c, and V3. SNMP V1 and SNMP V2c use a community
string match for authentication, which means that SNMP servers access all objects with read-only
or read/write permissions using the community strings public and private by default. SNMP V3
requires that you select an authentication level of MD5 or SHA, and is the most secure protocol.
You can also enable data encryption to enhance data security.
Supported SNMP security modes and levels are shown in the following table. Select the security
mode and level that will be used to communicate between the SNMP agent and manager.
