Advanced Port Configuration; Configuring Vlans - 3Com Baseline 2848-SFP Plus User Manual

Advanced Port Configuration

Use the Advanced Port Configuration tab to set the
Switch's broadcast storm control and threshold limits.
A broadcast storm is an incorrect packet sent out on a
network that causes most hosts to respond all at once,
typically with wrong answers that start the process over
again. Broadcast storms use substantial network
bandwidth and may cause network time-outs.
Advanced settings include:
Broadcast Storm Control – Enables and disables
■
broadcast storm control
Packet Rate Threshold – Sets the broadcast storm
■
threshold (64 to 95232000 bytes per packet)

Configuring VLANs

A virtual LAN (VLAN) is a collection of network nodes
that share the same collision domain, regardless of their
physical location or connection point in the network. A
VLAN serves as a logical workgroup with no physical
barriers, and allows users to share information and
resources as though located on the same LAN.
You can use the Switch to create VLANs to organize any
group of ports into separate broadcast domains. VLANs
confine broadcast traffic to the originating group and
help eliminate broadcast storms in large networks. This
also provides for a more secure and cleaner network
environment.
Using the Switch, you can create up to 64 VLANs, add
specific ports to a chosen VLAN (so that the port can
only communicate with other ports on the VLAN), or
configure a port make it a member of all VLANs.
