802.1p Port Traffic Class Information
This switch provides two priority levels with weighted fair queuing for
port egress. This means that any frames with a default or user priority
from 0-3 are sent to the low priority queue “0” while those from 4-7 are
sent to the high priority queue “1” as shown in the following screen:
Configuring
Virtual LANs
Use the VLAN Configuration menu to assign any port on the switch to
any of up to 16 LAN groups. In conventional networks with routers,
broadcast traffic is split up into separate domains. Switches do not
inherently support broadcast domains. This can lead to broadcast
storms in large networks that handle a lot of IPX traffic. By using IEEE
802.1Q compliant VLANs and GARP VLAN Registration Protocol, you can
organize any group of network nodes into separate broadcast domains,
confining broadcast traffic to the originating group. This also provides a
more secure and much cleaner network environment.
For a more detailed description of how to use VLANs, see Chapter 4. The
VLAN configuration screens are described in the following sections.
