Configuring Unidirectional Ethernet
This chapter describes how to configure Unidirectional Ethernet on the Catalyst 4500 series switch and
contains these sections:
• Overview of Unidirectional Ethernet, page 22-1
• Configuring Unidirectional Ethernet, page 22-1
Note For complete syntax and usage information for the switch commands used in this chapter, refer to the
Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/index.htm.
Overview of Unidirectional Ethernet
You can set non-blocking GigaPorts to unidirectionally transmit or receive traffic. Unidirectional
Ethernet uses only one strand of fiber for either transmitting or receiving one-way traffic for the
GigaPort, instead of two strands of fiber for a full-duplex GigaPort Ethernet. Configuring your GigaPorts
either to transmit or receive traffic effectively doubles the amount of traffic capabilities for applications,
such as video streaming, where most traffic is sent as unacknowledged unidirectional video broadcast
streams.
Configuring Unidirectional Ethernet
Note You must configure Unidirectional Ethernet on the non-blocking GigaPort, which will automatically
disable UDLD on the port.
