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.
Console(config)#snmp-server view mib-2 1.3.6.1.2.1 included
Console(config)#snmp-server view 802.1d 1.3.6.1.2.1.17 included
Console(config)#snmp-server group r&d v3 auth read mib-2 write 802.1d
Console(config)#snmp-server user steve group r&d v3 auth md5 greenpeace priv
des56 einstien
Console(config)#
For a more detailed explanation on how to configure the switch for access from
SNMP v3 clients, refer to the specific CLI commands for SNMP starting on page 151.
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 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 FTP/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 switch initialization, including
information about the unit identifier, and MAC address for the switch. 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 58 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 “File Management” on page 103 for
more information.
