Basic port parameter configuration
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• FESX compact switches – portnum
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both.
You can enable maximum port speed advertisement on one or two ports at a time.
To disable maximum port speed advertisement after it has been enabled, enter the no form of the
command.
Modifying port duplex mode
You can manually configure a 10/100 Mbps port to accept either full-duplex (bi-directional) or
half-duplex (uni-directional) traffic.
NOTE
You can modify the port duplex mode of copper ports only. This feature does not apply to fiber ports.
Port duplex mode and port speed are modified by the same command.
Port duplex mode configuration syntax
To change the port speed of interface 8 from the default of 10/100/1000 auto-sense to 10 Mbps
operating at full-duplex, enter the following.
Brocade(config)# interface ethernet 8
Brocade(config-if-e1000-8)# speed-duplex 10-full
Syntax: speed-duplex <value>
The <value> can be one of the following:
• 10-full
• 10-half
• 100-full
• 100-half
• auto (default)
MDI and MDIX configuration
Brocade devices support automatic Media Dependent Interface (MDI) and Media Dependent
Interface Crossover (MDIX) detection on all Gbps Ethernet Copper ports.
MDI/MDIX is a type of Ethernet port connection using twisted pair cabling. The standard wiring for
end stations is MDI, whereas the standard wiring for hubs and switches is MDIX. MDI ports
connect to MDIX ports using straight-through twisted pair cabling. For example, an end station
connected to a hub or a switch uses a straight-through cable. MDI-to-MDI and MDIX-to-MDIX
connections use crossover twisted pair cabling. So, two end stations connected to each other, or
two hubs or switches connected to each other, use crossover cable.
The auto MDI/MDIX detection feature can automatically correct errors in cable selection, making
the distinction between a straight-through cable and a crossover cable insignificant.
