Features

Ethernet ports are labeled 1 to 4 for documentation purposes.

SDSL ports are connected via the backplane.

There are no specific uplink ports. All ports are functionally identical.

The link and speed status of each Ethernet and SDSL port is indicated by status LEDs (see “Connectors and Indicators”).

The switch learns Ethernet addresses by analyzing received frames and stores them in the query.

The switch learns Ethernet addresses by analyzing received frames and stores them in a lookup table (up to 2048 entries),

used to forward frames only to the correct port. If the frame is

widecast or multicast, or the destination address is not found in the lookup table, the received frame is forwarded to the correct port.

then the received frame is forwarded to all ports except the receive port.

Receive port. If an entry in the lookup table is not refreshed by an incoming frame with a specific source address

then it is aged out for a maximum of 304 seconds.

Maximum 304 seconds (default, configurable).

For IEEE 802.1Q VLAN frames, the switch can be configured in VLAN or transparent mode. In transparent mode

the switch does not change any frames or frame TAGs; in VLAN

mode, the switch can be configured to support a variety of applications, such as

trunking or access ports.
