Defining SNMPv1/v2 communities

Access rights in SNMPv1 and SNMPv2 are managed by defining communities in the Configure communities dialog,
which is available after clicking Traditional access control. The community name is a type of shared password between
the SNMP management station and the device. It is used to authenticate the SNMP management station.
Communities are only defined in SNMPv1 and v2 because SNMP v3 works with users instead of communities. The users
belong to groups that have access rights assigned to them.
