SNMP > Global Parameters
Local Engine ID
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.
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

access is granted via the MIB name, or MIB Object ID.
