The following example checks for ports with active breakout configuration and then removes breakout
from ports 1/3/1 through 1/3/6.

Device(config)# end
Device# reload
NOTE
If there had been any configuration on any sub-ports (1/3/1:1 to 1/3/6:4), the
no
breakout
command would have returned an error. The configuration would
then have to be removed from the sub-ports before breakout configuration
could be removed.
The following example shows a failed attempt to remove breakout from port
1/1/5 as indicated by the error message. Configuration is then removed from
sub-port 1/1/5:1 before the breakout configuration is successfully removed.
Once the updated configuration is loaded, the ports are restored as full 40 Gbps
ports. The former sub-port configuration is not retained in memory.
device(config)# no breakout ethernet 1/1/5
Error: Port 1/1/5:1 is tagged
device(config)# vlan 200
device(config-vlan-200)# no tagged ethernet 1/1/5:1
Deleted tagged port(s) to port-vlan 200.
device(config)# end
device# configure terminal
device(config)# no breakout ethernet 1/1/5
Reload required. Please write memory and then reload or power cycle.
device(config)# end
device# write memory
Write startup-config done.
