A group is a label for a combination of attributes that determines whether
members have read, write, and/or notify privileges. Users can be associated
with a group. A group is operational only when it is associated with an
SNMP user.
SNMP Global Parameters
The Engine ID is used by SNMPv3 entities to uniquely identify themselves.
Both a remote and local Engine ID can be specified.
An SNMP agent is considered an authoritative SNMP engine. This means
that the agent responds to incoming messages (Get, GetNext, GetBulk, Set),
and sends trap messages to a manager. The agent's local information is
encapsulated in fields in the message.
Each SNMP agent maintains local information that is used in SNMPv3
message exchanges (not relevant for SNMPv1 or SNMPv2). The default
SNMP Engine ID is comprised of the enterprise number and the default
MAC address. The SNMP engine ID must be unique for the administrative
domain, so that no two devices in a network have the same engine ID.
The local information is stored in four read-only MIB variables:
snmpEngineId, snmpEngineBoots, snmpEngineTime, and
snmpEngineMaxMessageSize.
To configure SNMP:
1 Click System > SNMP > Global Parameters in the tree view to display
the Global Parameters page.
The global parameters are displayed.
2 Enter the fields:
– Local Engine ID (10-64 Hex Characters) — Check and enter 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.
– Use Default — Check to use 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
= 674.
