MDI and MDIX configuration notes
• This feature applies to copper ports only.
• The mdi-mdix mdi and mdi-mdix mdix commands work independently of auto-negotiation. Thus,
these commands work whether auto-negotiation is turned ON or OFF.
MDI and MDIX configuration syntax
The auto MDI/MDIX detection feature is enabled on all Gbps copper ports by default. For each port,
you can disable auto MDI/MDIX, designate the port as an MDI port, or designate the port as an MDIX
port.
To turn off automatic MDI/MDIX detection and define a port as an MDI only port.
device(config-if-e1000-2)# mdi-mdix mdi
To turn off automatic MDI/MDIX detection and define a port as an MDIX only port.
device(config-if-e1000-2)# mdi-mdix mdix
To turn on automatic MDI/MDIX detection on a port that was previously set as an MDI or MDIX port.
device(config-if-e1000-2)# mdi-mdix auto
Syntax: mdi-mdix[ mdi | mdix | auto ]
After you enter the mdi-mdix command, the Brocade device resets the port and applies the change.
To display the MDI/MDIX settings, including the configured value and the actual resolved setting (for
mdi-mdix auto), enter the command show interface at any level of the CLI.
Disabling or re-enabling a port
A port can be made inactive (disable) or active (enable) by selecting the appropriate status option. The
default value for a port is enabled.
To disable port 8 of a Brocade device, enter the following.
device(config)
# interface ethernet 8
device(config-if-e1000-8)# disable
You also can disable or re-enable a virtual interface. To do so, enter commands such as the following.
device(config)
# interface ve v1
device(config-vif-1)# disable
Syntax: disable
To re-enable a virtual interface, enter the enable command at the Interface configuration level. For
example, to re-enable virtual interface v1, enter the enable command.
device(config-vif-1)# enable
Syntax: enable
