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: 1-26 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

snmp-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 117

).

Example

Console(config)#snmp-server engine-id local 1234567890

Console(config)#snmp-server engineID remote 9876543210 192.168.1.19

Console(config)#
