SNMPv3 Commands

snmp-server
engine-id
This command configures an identification string for the SNMPv3 engine. Use the
no form to restore the default.
Syntax
snmp-server engine-id {local | remote {ip-address}} engineid-string
no snmp-server engine-id {local | remote {ip-address}}
local - Specifies the SNMP engine on this switch.
remote - Specifies an SNMP engine on a remote device.
ip-address - The Internet address of the remote device.
engineid-string - String identifying the engine ID. (Range: 9-64 hexadecimal
characters)
Default Setting
A unique engine ID is automatically generated by the switch based on its MAC
address.
Command Mode
Global Configuration
Command Usage
An SNMP engine is an independent SNMP agent that resides either on this
switch or on a remote device. This engine protects against message replay,
delay, and redirection. The engine ID is also used in combination with user
passwords to generate the security keys for authenticating and encrypting
SNMPv3 packets.
A remote engine ID is required when using SNMPv3 informs. (See the
server host
command.) The remote engine ID is used to compute the security
digest for authentication and encryption of packets passed between the switch
and a user on the remote host. SNMP passwords are localized using the engine
ID of the authoritative agent. For informs, the authoritative SNMP agent is the
remote agent. You therefore need to configure the remote agent's SNMP
engine ID before you can send proxy requests or informs to it.
Trailing zeroes need not be entered to uniquely specify a engine ID. In other
words, the value "0123456789" is equivalent to "0123456789" followed by 16
zeroes for a local engine ID.
A local engine ID is automatically generated that is unique to the switch. This is
referred to as the default engine ID. If the local engine ID is deleted or changed,
all SNMP users will be cleared. You will need to reconfigure all existing users
(page
147).
