Configuring SNMP version 3 on the BigIron RX
To configure SNMP version 3 on the BigIron RX, do the following.
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
2. Create views that will be assigned to SNMP user groups using the snmp-server view command.
on page 1103 for details.
3. Create ACL groups that will be assigned to SNMP user groups using the access-list command.
Chapter 22, “Access Control List”
for details.
4. Create user groups using the snmp-server group command. Refer to
5. Create user accounts and associate these accounts to user groups using the snmp-server user
command. Refer to
“Defining an SNMP user account”
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
on page 1101 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.
BigIron RX(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
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:
•
Octets 1 through 4 represent the agent's SNMP management private enterprise number as
assigned by the Internet Assigned Numbers Authority (IANA). The most significant bit of Octet 1
is "1". For example, “000007c7” is the ID for Brocade in hexadecimal. With Octet 1 always
equal to "1", the first four octets in the default engine ID is always “800007c7” (which is 1991
in decimal).
•
Octet 5 is always 03 in hexadecimal and indicates that the next set of values represent a MAC
address.
