Establishing SNMP community strings
3. Configure the SNMP version 3 features in devices.
Configuring SNMP version 3
Follow the steps given below to configure SNMP version 3 on devices.
1. Enter an engine ID for the management module using the snmp-server engineid command if
you will not use the default engine ID.Refer to “Defining the engine id” on page 167.
2. Create views that will be assigned to SNMP user groups using the snmp-server view command.
refer to “SNMP v3 Configuration examples” on page 175 for details.
3. Create ACL groups that will be assigned to SNMP user groups using the access-list command.
4. Create user groups using the snmp-server group command.Refer to “Defining an SNMP group”
on page 168.
5. Create user accounts and associate these accounts to user groups using the snmp-server user
command.Refer to “Defining an SNMP user account” on page 169.
If SNMP version 3 is not configured, then community strings by default are used to authenticate
access.
Defining the engine id
A default engine ID is generated during system start up. To determine what the default engine ID of
the device is, enter the show snmp engineid command and find the following line:
Local SNMP Engine ID: 800007c70300e05290ab60
See the section “Displaying the Engine ID” on page 174 for details.
The default engine ID guarantees the uniqueness of the engine ID for SNMP version 3. If you want
to change the default engine ID, enter a command such as the following.
TurboIron(config)#snmp-server engineid local 800007c70300e05290ab60
Syntax: [no] snmp-server engineid local <hex-string>
The local parameter indicates that engine ID to be entered is the ID of this device, representing an
SNMP management entity.
NOTE
Each user localized key depends on the SNMP server engine ID, so all users need to be reconfigured
whenever the SNMP server engine ID changes.
NOTE
Since the current implementation of SNMP version 3 does not support Notification, remote engine
IDs cannot be configured at this time.
The <hex-string> variable consists of 11 octets, entered as hexadecimal values. There are two
hexadecimal characters in each octet. There should be an even number of hexadecimal characters
in an engine ID.
The default engine ID has a maximum of 11 octets:
