Splitting 40G Ports Without Reload - Dell S4048–ON Configuration Manual

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, configure profile first before provisioning for new units. Otherwise it is mandatory to reload for profile to take effect.
• If there is a mismatch in fan-out profile between master and the new member in stacking, the master re-configures the member with
its quad-mode profile, quad-mode, and stack-group configuration and then reset the member. To avoid stack split during profile
mismatch, the master does stack group configurations of the new member.
To configure the quad-port-profile, 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 profile, use the following show command:
show system stack-unit stack-unit number fanout configured
