11.3.1 Defining SNMP Global Parameters
The SNMP Security Global Parameters Page permits the enabling of both SNMP and Authentication notifications.
To define SNMP security global parameters:
1. Click
System > SNMP Management > Security > Global Parameters. The SNMP Security Global Parameters Page
opens:
Figure 100: SNMP Security Global Parameters Page
The SNMP Security Global Parameters Page contains the
following fields:
Local Engine ID (0-32 Characters) — Displays the
local device Engine ID. The field value is a hexadecimal
string. Each byte in hexadecimal character strings
is two hexadecimal digits. Each byte can be separated by a period or a colon. The Engine ID must be defined before
SNMPv3 is enabled. Select a default Engine ID that is comprised of an Enterprise number and the default MAC address.
Use Default — Uses the device-generated Engine ID. The default Engine ID is based on the device MAC address and
is defined per standard as:
– First 4 octets — first bit = 1, the rest is IANA Enterprise number.
– Fifth octet — Set to 3 to indicate the MAC address that follows.
– Last 6 octets — MAC address of the device.
2. Define the Local Engine ID and Use Default fields.
3. Click . The SNMP global security parameters are set, and the device is updated.
11.3.2 Defining SNMP Views
SNMP Insert space views provide or block access to device features or portions of features. For example, a view can be
defined which provides that SNMP group A has Read Only (R/O) access to Multicast groups, while SNMP group B has
Read-Write (R/W) access to Multicast groups. Feature access is granted via the MIB name or MIB Object ID.
To define SNMP views:
1. Click
System > SNMP Management > Security > Views. The SNMP Security Views Page opens:
Figure 101: SNMP Security Views Page
The SNMP Security Views Page contains the following
fields:
View Name — Displays the user-defined views. The
view name can contain a maximum of 30 alphanumeric
characters.
Object ID Subtree — Displays the device feature OID
included in or excluded from the selected SNMP view.
View Type — Indicates whether the defined OID
branch will be included in or excluded from the selected
