Provides data security by restricting all traffic to the originating
VLAN, except where a connection has been configured
between separate VLANs using a router or Layer 3 switch.
Multicast Switching
Specific multicast traffic can be assigned to its own VLAN to ensure
that it does not interfere with normal network traffic and to
guarantee real-time delivery by setting the required priority level
for the designated VLAN. The switch uses IGMP Snooping and
IGMP to manage multicast group registration.
Traffic Priority
This switch provides Quality of Service (QoS) by prioritizing each
packet based on the required level of service, using two distinct
categories with Weighted Fair Queuing. It uses IEEE 802.1p and
802.1Q tags to prioritize incoming traffic based on input from the
end-station application. These functions can be used to provide
independent priorities for delay-sensitive data and best-effort data.
Optional Media Extender Modules
Optional 100BASE-FX Module (SMC6900FSC)
Figure 1-6. 2-Port 100BASE-FX Fiber Module
Using fiber optic cable, the 100BASE-FX port can be connected to
a remote site up to 2 km (1.24 mi.) away. This port operates only
at 100 Mbps, full duplex. This module is fitted with an SC
connector, but you can attach an ST plug to the switch using the
optional SC-ST Converter (Part Number: 99-012034-091).
