Brocade Communications Systems 6650 Defining an Snmp group, Snmp version 3. If you want command

6 User-based security model

See the section “Displaying the Engine ID” on page 167 for details.

The default engine ID guarantees the uniqueness of the engine ID for to change the default engine ID, enter the snmp-server engineid local

SNMP version 3. If you want command.

Brocade(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:

•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 Communications, Inc. 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.

•Octets 6 through 11 form the MAC address of the lowest port in the management module.

NOTE

Engine ID must be a unique number among the various SNMP engines in the management domain. Using the default engine ID ensures the uniqueness of the numbers.

Defining an SNMP group

SNMP groups map SNMP users to SNMP views. For each SNMP group, you can configure a read view, a write view, or both. Users who are mapped to a group will use its views for access control.

To configure an SNMP user group, enter a command such as the following.

Brocade(config)#snmp-server group admin v3 auth read all write all

Syntax: [no] snmp-server group <groupname> v1 v2 v3 auth noauth priv [access <standard-ACL-id>] [read <viewstring> write <viewstring>]
