Accessing devices within different SNMP communities
SNMP community passwords can provide a level of protection by limiting access
to devices. In Optivity Switch Manager, you can access subnets with different
communities by adding the correct SNMP passwords in the Communities dialog
box. SNMP devices, which include those devices supported by Optivity Switch
Manager, typically have two passwords or communities for read and write
operations on that device. The two passwords are “public” (open access) and
“private” (restrictive access).
By default, Optivity Switch Manager reads an ASCII file (snmpcomm.properties)
that contains one entry. That entry allows Optivity Switch Manager to access all
devices in the discovered network using “public” as the community password for
read operations and “private” as the password for write operations. If devices
contain a different SNMP community password, you cannot access them unless
you know their passwords and enter those password into the Optivity Switch
Manager snmpcomm.properties file.
To assign a different SNMP community password to a group or single device:
1 From the Optivity Switch Manager menu bar, choose Edit > Communities.
The Communities dialog box opens (Figure 13).
