AT-FS20x Series Installation Guide

Switch Performance

The AT-FS20x switches have the following performance values:

148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire speed forwarding and filtering

200 Mbps maximum throughput in 100 Mbps, full-duplex mode

20 Mbps maximum throughput in 10 Mbps, full-duplex mode

Storage for up to 4,000 MAC addresses

280 kilo bytes (per port) packet buffer

Low latency 15.6 ∝s (64-byte packet, 100 Mbps full-duplex)

DIP Switches

The DIP switches are used to manually configure the operating characteristics of the ports. These characteristics include the port speed, duplex mode, and Auto-Negotiation.

On the 100Base-FX fiber optic port, you can manually set the duplex mode to either half- or full-duplex.

On the 10Base-T/100Base-TX twisted-pair port, you can manually set the speed of the port to either 10 Mbps or 100 Mbps, set the duplex mode to either half- or full-duplex and enable or disable Auto-Negotiation. Enabling Auto- Negotiation automatically sets the port’s speed and duplex mode.

MAC Address Table

Up to 4,000 MAC addresses can be stored in the switch’s MAC address table. After power-up, the switch’s self-learning feature learns new addresses in real-time. If the source address of an incoming packet is not found in the MAC address table, the switch updates the table with the new address.

The switch also has an automatic address aging feature that deletes a source address from the table if it has not received a frame from the end-node with that address within five minutes. This prevents the table from becoming filled with addresses of end-nodes that are no longer active.

The switch forwards all multicast, broadcast, and unicast packets when the MAC address table has exceeded its storage limit.
