Multi-Gigabit; Ipv6 And Ipv6 Firewall; Applications For The Nbg7815 - ZyXEL Communications NBG7815 User Manual

1.1.1 Multi-Gigabit

A 10 Gigabit port supports speed of 10 Gbps if the connected device supports 10 Gbps and a Cat 6a
(up to 100 m) or Cat 6 cable (up to 50 m) is used. The speed drops to 1G if these criteria are not met; it
drops to 100 Mbps if a Cat 5 cable is used (up to 100 m).
If a network device such as a 5G network card, gaming computer, server, Network Attached Storage
(NAS) or Access Point (AP) only supports 2.5 Gigabit or 5 Gigabit connectivity, then the maximum speed
potential of these devices is never reached.
In addition, at the time of writing, most existing cabling is Cat 5e or Cat 6, further limiting maximum
speed or distance potential.
Multi-Gigabit (IEEE 802.3bz) solves these problems by additionally supporting 2.5 Gigabit and 5 Gigabit
Ethernet connections over Cat 5e and higher Ethernet cables. Multi-Gigabit ports are also backward
compatible with 100 Mbps and 1 Gigabit ports.
See the following table for the cables required and distance limitation to attain the corresponding
speed.

1.1.2 IPv6 and IPv6 Firewall

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
NBG7815 can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and support IPv6 rapid
deployment (6RD).
See the LAN chapter in the User's Guide for information on configuring IPv6 in NBG7815.
Consequently, you can enable and create IPv6 firewall rules to filter IPv6 traffic.
See the Security chapter in the User's Guide for information on configuring IPv6 firewall in NBG7815.
