The SNMP Security Global Parameters Page contains the
following elds:
Local Engine ID (0-32 Characters) — Displays the
local device Engine ID. The eld 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 dened 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 dened per standard as:
– First 4 octets — rst 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.
