Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that contains
bits to define class of service. Frames without an explicit priority tag are given the default priority of the
ingress port. Use the next fields to configure the priority level-to-physical queue mapping.
The Switch has eight physical queues that you can map to the 8 priority levels. On the Switch, traffic assigned
to higher index queues gets through faster while traffic in lower index queues is dropped if the network is
congested.

8.6 IPv6 Introduction

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
addresses.

8.6.1 IPv6 Addressing

The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can
be written as 2001:db8:1a2b:15:0:0:1a2f:0.

DESCRIPTION
Leave Time sets the duration of the Leave Period timer for GVRP in milliseconds. Each port
has a single Leave Period timer. Leave Time must be two times larger than Join Timer;
the default is 600 milliseconds.
Leave All Timer sets the duration of the Leave All Period timer for GVRP in milliseconds. Each
port has a single Leave All Period timer. Leave All Timer must be larger than Leave Timer.
Typically used for network control traffic such as router configuration messages.
Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in
delay).
Typically used for video that consumes high bandwidth and is sensitive to jitter.
Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.
Typically used for "excellent effort" or better than best effort and would include important
business traffic that can tolerate some delay.
This is for "spare bandwidth".
This is typically used for non-critical "background" traffic such as bulk transfers that are
allowed but that should not affect other applications and users.
Typically used for best-effort traffic.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
