Physical Ports
This switch provides:
•Eight 10/100BaseTX ports
•Seven 10/100BaseTX ports + one 100BaseFX port
•Six 10/100BaseTX ports + two 100BaseFX ports
CONNECTIVITY
•RJ-45 connectors
•ST or SC connector on 100BaseFX fiber port.
MODE SELECTION
•10BaseT full-duplex mode
•10BaseT half-duplex mode
•100BaseTX full-duplex mode
•100BaseTX half-duplex mode
•100BaseFX full-duplex mode
•Auto-sensing mode (Copper Ports)
<Note>
i. Half-duplex mode uses back pressure flow control to prevent the receiving
buffer from being overrun by data from a source node.
ii. Full-duplex mode uses 802.3x flow control standard to prevent fast data
traffic from overrunning slow data traffic.
iii. Auto-sensing mode is in use after auto-negotiating with the other end of the
link.

Basic Functions
In general, the switch is responsible for switching both VLAN
tagged and untagged frames from a receiving port to one or
more transmitting ports. The switch performs multiple steps
during the switching process:
VLAN CLASSIFICATION
LEARNING
FILTERING
FORWARDING
AGING
Below is additional information about tasks that the switch
performs during unicast and multicast switching.
