Bridging Converter Performance

Overview

Note

MissingLink or Smart MissingLink is disabled when you perform a link test. Consequently, to ensure that the MissingLink or Smart MissingLink is enabled on the bridging converter, always set the Mode Selection button so that the ML or SML LED is green during normal network operations.

Smart MissingLink

Like MissingLink, the Smart MissingLink feature terminates the link on the failed port thereby notifying you when a connection has been lost. Additionally, Smart MissingLink indicates on which port the connection has failed. This is shown by a blinking LNK LED on the good port.

For example, if the network twisted pair cable to the 10Base-T/100Base-TX port on the bridging converter were to fail, the LNK LED on the 100Base-FX fiber optic port will blink, indicating a failed connection on the twisted pair port. The fiber optic port is still able to receive a signal.

The bridging converter notifies the end-node connected to the fiber optic port that the connection on the twisted pair port has been lost. If the failure had started with the fiber optic cabling, the LNK LED on the twisted pair port would blink.

The value to this type of network monitoring and fault notification is so that you can quickly see which port has failed and troubleshoot your network accordingly.

The bridging converters perform at:

❑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 2k MAC addresses

❑280 kB (per port) packet buffer

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