1.2.5 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, SSH, 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 Appendix C on page 618 and the CLI Reference Guide.
1.3 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 45 .
• 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 File Transfer Protocol for firmware upgrades and configuration backup or restore. See Section
58.9.1 on page 532 .
• SNMP. The Switch can be monitored and/or managed by an SNMP manager. See Section 59.7.1 on
page 546 .
• Cluster Management. Cluster Management allows you to manage multiple switches through one
switch, called the cluster manager. See Chapter 63 on page 568 .
• ZON Utility. ZON Utility is a program designed to help you deploy and perform initial setup on a
network more efficiently. See Section 4.3 on page 48 .
1.4 Good Habits for Managing the Switch
Do the following regularly to make the Switch more secure and to manage the Switch more effectively.
• Change the password. Use a password that is 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.
