character strings is two hexadecimal digits. Each byte can be separated by a period or a colon.
• Privacy Key. Defines the Privacy Key (LSB). If only authentication is required, 20 bytes are defined. If both
privacy and authentication are required, 36 bytes are defined. Each byte in hexadecimal character strings is

Defining SNMP Communities
Access rights are managed by defining communities on the SNMPv1,2 SNMP Community screen. When the
community names are changed, access rights are also changed. SNMP Comminutes are defined only for SNMP
v1 and SNMP v2.
The SNMP Communities screen is divided into the following tables:
• SNMP Communities Basic Table
• SNMP Communities Advanced Tables
SNMP Communities Basic Table
Management Station. Displays the management station IP address for which the basic SNMP community is
defined.
Community String. Defines the password used to authenticate the management station to the device.
Access Mode. Defines the access rights of the community. The possible field values are:
• Read-Only - Management access is restricted to read-only, and changes cannot be made to the
community.
• Read-Write - Management access is read-write and changes can be made to the device configuration, but
not to the community.
