Before performing the following procedure, you can verify the current port configuration using the show interface status command:
-------------------------------------------------------------------------------- Port Status Mode Speed Type Description -------------------------------------------------------------------------------- Eth 0/1 adminDown -- -- -- Eth 0/2 adminDown -- -- -- Eth 0/3 adminDown -- -- -- Eth 0/4 adminDown -- -- -- Eth 0/5 adminDown -- -- --
Note
When configuring breakout mode - either breaking into multiple interfaces or consolidating into one interface - it is a best practice to remove all configuration on the interface, and set the interface to the disabled state.Perform the following steps:
device# configure terminal
device (config)# interface ethernet 0/1 shutdown exit
Or;
device (config)# interface ethernet 0/1:1-4 shutdown exit
device(config)# hardware
device(config-hardware)# connector 0/1
device(config-connector-0/1)# breakout mode 4x10g
Note
Dynamic breakout is supported; the user does not need to reboot the switch to execute the breakout.device(config-connector-0/1)# exit device(config-hardware)# exit device(config)#
device(config)# show interface status -------------------------------------------------------------------------------- Port Status Mode Speed Type Description -------------------------------------------------------------------------------- Eth 0/1:1 adminDown -- -- -- Eth 0/1:2 adminDown -- -- -- Eth 0/1:3 adminDown -- -- -- Eth 0/1:4 adminDown -- -- -- Eth 0/2 adminDown -- -- -- Eth 0/3 adminDown -- -- -- Eth 0/4 adminDown -- -- -- Eth 0/5 adminDown -- -- --
