1.2.5.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain thereby increase network
performance through reduced 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 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 629 and the CLI Reference Guide.
1.3 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• NCC (Zyxel Nebula Control Center). With the NCC, you can remotely manage and monitor the
Switch through a cloud-based network management system. See the NCC User’s Guide for detailed
information about how to access the NCC and manage your Switch through the NCC. See the NCC
User’s Guide for how to configure Nebula managed devices.
