• You can configure a disabled port as a fanout port when the maximum limit is not exceeded. This
behavior reduces the number of reloads required to configure a disabled port in Quad mode to Non-
quad mode.
• When you configure 13 ports as fanout, a warning message is displayed stating that the maximum
number of ports that you can configure in Quad mode has been reached. The extra ports are disabled
the next time you reload the system.
• When you attempt to configure fanout on the ports where fanout feature is not supported, a warning
message displays stating that Quad mode ports limit has been reached and that you cannot configure
additional ports.
• For theshow hardware command, the valid range for the port-range parameter is from 0-127.
• Internal ports mapped to global ports may vary depending on the configured attributes. The show
hardware
command output using these internal ports is realigned according to the configured
settings.
• To view the disabled ports, you can use thedisabled-ports keyword with the show system
stack-unit 0 command.
• Before you configure the last available port in Quad mode, you are prompted to confirm whether you
want to configure the port Fanout mode, as shown in the following example.
Dell(conf)#stack-unit 0 port 0 portmode quad
Maximum number of ports that can be made Quad mode in the range <0-63> is
configured. Ports 12,16,60, will be disabled on reload.
Do you wish to continue? [confirm yes/no]:yes
Please save and reset unit 0 for the changes to take effect.
The following figure shows 26 ports configured in Quad mode. Ports X(52, 56, 60) and Y( 64, 68, 72) are
disabled (shown in red).
