directly talk to or hear from stations that are not in the same groups unless such traffic first goes through
a router.
For more information on VLANs, refer to Chapter 9 on page 76 .
1.2.5.1 Ta g - b a se d VLAN Exa m ple
Ports in the same VLAN group share the same frame broadcast domain, therefore increasing network
performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding,
moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the
following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to
other VLAN groups too.

1.2.6 IPv6 Suppo rt
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, telnet, SNMP, HTTP and TFTP 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
