Defining SNMP
Communities
Access rights are managed by defining communities in the SNMP
Communities Setup Page. When the community names are changed,
access rights are also changed. SNMP communities are defined only for
SNMP v1 and SNMP v2c.
Monitor users have no access to this page.
To define SNMP communities:
1 Click Administration > SNMP > Communities > Setup. The SNMP
Communities Setup Page opens:
Figure 73 SNMP Communities Setup Page
The SNMP Communities Setup Page contains the following fields:
■ SNMP Status — Specifies if SNMP is enabled on the device. The
possible field values are:
■ Enable — Enables SNMP on the device.
■ Disable — Disables SNMP on the device.
