4.11 SNMP

Simple Network Management Protocol (SNMP) provides a method for managing network devices. Devices supporting SNMP
run a local software (agent).
The SNMP agents maintain a list of variables, which are used to manage the device. The variables are defined in the
Management Information Base (MIB). The MIB contains the variables controlled by the agent. The SNMP protocol defines the
MIB specification format, as well as the format used to access the information over the network.
Access rights to the SNMP agents are controlled by access strings. To communicate with the device, the Embedded Web
Server submits a valid community string for authentication.

4.11.1 Global Parameters

The Global Parameters screen (see figure 4-61) contains parameters for defining SNMP notification parameters.
The Global Parameter Screen contains the following fields:
SNMPV3
Local Engine ID
Use Default
Figure 4-61 SNMP Global Parameter
Indicates the local device engine ID. The field value is a hexadecimal string. Each
byte in hexadecimal character strings consists of two hexadecimal digits. Each byte
can be separated by a period or a colon. The Engine ID must be defined before
SNMPv3 is enabled. For stand-alone devices, select a default Engine ID that is
comprised of Enterprise number and the default MAC address.
For a stackable system configure the Engine ID, and verify that the Engine ID is
unique for the administrative domain. This prevents two devices in a network from
having the same Engine ID.
Uses the device generated Engine ID. It's defined per standard as:
First 4 octets — first bit = 1, the rest is IANA Enterprise number. To locate the IANA
Enterprise number by referring to the Vendor website, or use the show SNMP
command using a CLI interface.
