Configuring Access for SNMP Version 3 Clients

To configure management access for SNMPv3 clients, you need to first create a

view that defines the portions of MIB that the client can read or write, assign the view

to a group, and then assign the user to a group. The following example creates one

view called “mib-2” that includes the entire MIB-2 tree branch, and then another view

that includes the IEEE 802.1d bridge MIB. It assigns these respective read and read/

write views to a group call “r&d” and specifies group authentication via MD5 or SHA.

In the last step, it assigns a v3 user to this group, indicating that MD5 will be used for

authentication, provides the password “greenpeace” for authentication, and the

password “einstien” for encryption.

For a more detailed explanation on how to configure the switch for access from

SNMP v3 clients, refer to “Simple Network Management Protocol” on page 5-1, or

refer to the specific CLI commands for SNMP starting on page 24-1.

Managing System Files

The switch’s flash memory supports three types of system files that can be managed

by the CLI program, web interface, or SNMP. The switch’s file system allows files to

be uploaded and downloaded, copied, deleted, and set as a start-up file.

The three types of files are:

• Configuration — This file type stores system configuration information and is

created when configuration settings are saved. Saved configuration files can be

selected as a system start-up file or can be uploaded via TFTP to a server for

backup. The file named “Factory_Default_Config.cfg” contains all the system

default settings and cannot be deleted from the system. If the system is booted with

the factory default settings, the master unit will also create a file named

“startup1.cfg” that contains system settings for stack initialization, including

information about the unit identifier, MAC address, and installed module type for

each unit the stack. The configuration settings from the factory defaults

configuration file are copied to this file, which is then used to boot the stack. See

“Saving or Restoring Configuration Settings” on page 4-24 for more information.

• Operation Code — System software that is executed after boot-up, also known as

run-time code. This code runs the switch operations and provides the CLI and web

management interfaces. See “Managing Firmware” on page 4-21 for more

information.
