Fanning out 40g Ports Dynamically


The device supports the Fan-out Interfaces without reboot on Dell Networking OS. It aims at converting the 40G ports into 10G mode without reboot. The switch has the facility to dynamically change the 40G port to 4X10G port and vice-versa without reload.

By adding this feature, the number of reloads are reduced and traffic disruption is only seen in fanned out or fanned in ports.
  • On a device, fan-out profile constructs automatically with default 24 ports (0,8,16,24,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,100,108,116,124) . These ports can be changed to 40G to 10G mode or vice-versa without reload.
  • When a non-supported profile release is upgraded to a supported profile release, the fan-out configured ports get automatically included in the profile. In fan-out mode, if a system is upgraded with 25 or 26 ports, only 24 ports get upgraded to fan-out mode. The rest of the ports put to default 40G mode.
  • 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 primary switch and the new member in stacking, the primary switch 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 primary switch controls the stack group configurations of the new member.
 


Verify quad-port-profile


To display the Fan-out capability profile, use the following show command:

show system stack-unit quad-port-profile

The following example shows the system stack-unit quad-port-profile command.

DellSwitch#show system stack-unit 0 quad-port-profile

Configure the quad-port-profile


To configure one of the default ports  (0,8,16,24,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,100,108,116,124) for quad mode run this command:

DellSwitch(conf)#stack-unit 1 port 24 portmode quad
Port 24 quad mode enabled


When attempting to configure a port not on the default list you will see an error.

DellSwitch(conf)#stack-unit 0 port 96 portmode quad
% Error: Quad mode is currently not activated on this port


In order to configure a port that is not a default port or is not listed in the show system stack-unit 0 quad-port-profile command you will have to modify the ports in the quad-port-profile with this command.
Example of adding port 96 and removing port 100 from the list.

DellSwitch(conf)# stack-unit 0 quad-port-profile 0,8,16,24,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96,108,116,124

 

A save and reload is required after modifying the quad port profile. Be aware that you are not just adding a port to the list you must remove a port to stay within the 24 port total limit.

 

Splitting 40g port to 10g ports


Now that you have a quad-port-profile established you can change any one of the ports listed in the quad-port-profile from 40g to 4 - 10g ports and vice versa without rebooting.
Example:

DellSwitch(conf)#stack-unit 1 port 4 portmode quad
Port 4 quad mode enabled

 

The quad port must be in a default configuration before you can split it into 4x10G ports. The 40G port is lost in the configuration when the port is split; be sure that the port is also removed from other L2/L3 feature configurations.


 

Verifying Configuration


To verify port splitting use this command:

DellSwitch# show system stack-unit 0 fanout {count | configure}

You will also see the ports from this command:

DellSwitch# show interface status
