Basic port parameter configuration

NOTE
You can modify the port speed of copper ports only; this feature does not apply to fiber ports.
NOTE
For optimal link operation, copper ports on devices that do not support 803.3u must be configured
with like parameters, such as speed (10,100,1000), duplex (half, full), MDI/MDIX, and Flow Control.
Port speed and duplex mode configuration syntax
The following commands change the port speed of copper interface 8 on a FastIron from the
default of 10/100/1000 auto-sense, to 100 Mbps operating in full-duplex mode.
Brocade(config)# interface ethernet 8
Brocade(config-if-e1000-8)# speed-duplex 100-full
Syntax: speed-duplex value
where value can be one of the following:
• 10-full – 10 Mbps, full duplex
• 10-half – 10 Mbps, half duplex
• 100-full – 100 Mbps, full duplex
• 100-half – 100 Mbps, half duplex
• 1000-full-master – 1 Gbps, full duplex master
• 1000-full-slave – 1 Gbps, full duplex slave
• auto – auto-negotiation
The default is auto (auto-negotiation).
Use the no form of the command to restore the default.
NOTE
On FastIron devices, when setting the speed and duplex-mode of an interface to 1000-full, configure
one side of the link as master (1000-full-master) and the other side as slave (1000-full-slave).
NOTE
On Brocade ICX 6610 devices, after you remove 10 Gbps speed from the running configuration,
plugging in a 1G optic SFP transceiver into a 10 Gbps port causes the software to fail to revert the
ports back from the default 10G LRM mode to 1 Gbps speed. Remove the 1G SFP transceiver and
plug in the 10G optic SFP+transceiver so that the Brocade ICX 6610 devices go into default 10 Gbps
LRM mode.
