2 Initial Configuration

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 11-1,or refer to the specific CLI commands for SNMP starting on page 40-1.

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 switch will also create a file named “startup1.cfg” that contains system settings for initialization. The configuration settings from the factory defaults configuration file are copied to this file, which is then used to boot the switch. See “Saving or Restoring Configuration Settings” on page 6-4for 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 6-1for more information.

Diagnostic Code — Software that is run during system boot-up, also known as POST (Power On Self-Test).
