Figure 6-57. SNMP Global Parameters
The
SNMP Global Parameters
page contains the following fields:
Local Engine ID
— 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 Defaults
— 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 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.
