Configuring System Information
221
The SNMP Global Parameters page contains the following fields:
• Local Engine ID (10-64 Hex Characters) — Indicates 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.
– 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 — Select 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.
– Fifth octet — Set to 3 to indicate the MAC address that follows.
– Last 6 octets — MAC address of the device.
• SNMP Notifications — Enables or disables the router sending SNMP notifications.
• Authentication Notifications — Enables or disables the router sending SNMP traps when
authentication fails.
