1.1.5 IPv6 Support
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
38
IP
addresses. At the time of writing, the Switch supports the following features.
• Static address assignment and stateless auto-configuration
• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)
• Remote Management using ping SNMP, telnet, HTTP and FTP services
• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such
as "ping”
• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time
• DHCPv6 client and relay
• Multicast Listener Discovery (MLD) snooping and proxy
For more information on IPv6, refer to the CLI Reference Guide.
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 4 on page 35 .
• Command Line Interface. Line commands offer an alternative to the web configurator and in
some cases are necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 39.9 on page
300 .
• SNMP. The Switch can be monitored by an SNMP manager. See Section 40.3 on page 303 .
• Cluster Management. Cluster Management allows you to manage multiple switches through one
switch, called the cluster manager. See Chapter 43 on page 329 .
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the Switch to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the Switch. You
could simply restore your last configuration.
