Splitting 40G Ports without Reload
You can split 40G interfaces into 10G ports without reboot. You can also combine the split ports to create a 40G port without reload.
• The switch consists of six 40G ports (49,50,51,52,53,54) that can be split into 10G ports.
• In stacking, congure prole rst before provisioning for new units. Otherwise it is mandatory to reload for prole to take eect.
• If there is a mismatch in fan-out prole between master and the new member in stacking, the master re-congures the member with
its quad-mode prole, quad-mode, and stack-group conguration and then reset the member. To avoid stack split during prole
mismatch, the master does stack group congurations of the new member.
To congure the quad-port-prole, use the following command:
CONFIGURATION mode
stack-unit stack-unit number port port-number portmode quad
The defaults ports are:
49,50,51,52,53,54
To display the Fan-out capability prole, use the following show command:
show system stack-unit stack-unit number fanout configured
Example of the
show Command
The following example shows the show system stack-unit stack-unit number fanout
configured command.
