3.3.3.1 SNMPv2
For most devices, only read communities are used during discovery. Some devices, including iMG/RGs, require discovering
write communities as well.
Communities will be attempted in the order displayed. The order may be modified by selecting a row and then clicking on the
up/down buttons.
Communities may be added, modified, or deleted with the Add, Modify or Delete Buttons. The Add button will add to the list
whatever is in the Read or Write text field. The Modify button will replace whatever is in the selected row with whatever has
been typed in the Read or Write text field.
The SNMP agent port, timeout, and retry count can be configured as well. The defaults are 161, 10, and 0 respectively.
Whereas 161 is the most commonly used SNMP agent port, others can be added as a space-separated list. Each port will be
tried in the given order.
3.3.3.2 SNMPv3
There is the option enable SNMPv3 Discovery, which adds security and administration features. (For information on the rela-
tionships between the SNMP versions refer to RFC 3416.)
The SNMP panel allows the addition of Users following the User-based security model defined in RFC 3414. As RFC 3416,
states, it is up to the only those principals (users) having legitimate rights can access or modify the values of any MIB objects
supported by that entity.
The SNMP panel includes the Enable SNMPv3 Discovery option, as shown in Figure 3-2. User Names are added by typing in
the User Name field, the Context Field, and then selecting Add. Names can continue to be added and the order changed using
the direction arrows. A name can be modified by selecting a name, changing the name in the User name field, and selecting
Modify. Selecting Save Changes writes the values to the NMS
