4.0 OPERATION

This chapter describes the functions and operation of the Magnum 6K32T &

6K32TRC Switch.


4.1 Switching

Functionality

A Magnum 6K32T & 6K32TRC provides switched connectivity at Ethernet

wire-speed among all of its ports. The Magnum 6K32T & 6K32TRC support 10/100Mbs

for copper media and 10 or 100Mb separate traffic domains for fiber ports to maximize

bandwidth utilization and network performance. All ports can communicate to all other

ports in a Magnum 6K32T & 6K32TRC, but local traffic on a port will not consume any

of the bandwidth on any other port.

Magnum 6K32T & 6K32TRC units are plug-and-play devices. There is no

software configuring necessary to be done for basic operation at installation or for

maintenance. The only hardware configuration settings are user options for an UP-LINK

Switch (resides inside the unit) on the 6K8-RJ45 (modular port). Optional Half / Full

duplex mode and 10 or 100Mbps selection for the switched ports must be configured

through MNS-6K software per unit as per the requirement. The internal functions of both

are described below.

Filtering and Forwarding

Each time a packet arrives on one of the switched ports, the decision is taken to

either filter or to forward the packet. Packets whose source and destination addresses are

on the same port segment will be filtered, constraining them to that one port and relieving

the rest of the network from having to process them. A packet whose destination address

is on another port segment will be forwarded to the appropriate port, and will not be sent

to the other ports where it is not needed. Traffic needed for maintaining the operation of

the network (such as occasional multi-cast packets) are being forwarded to all ports.

The Magnum 6K32T & 6K32TRC Switches operate in the store-and-forward

switching mode, which eliminates bad packets and enables peak performance to be

achieved when there is heavy traffic on the network.

Address Learning

All Magnum 6K32T & 6K32TRC units have address table capacities of 4K

node addresses suitable for use in larger networks. They are self-learning, so as nodes are

added, removed or moved from one segment to another, the 6K32T & 6K32TRC Switch

automatically keeps up with node locations.
