To configure the uplink speed of the member interfaces in a LAG bundle for the Aggregator that operates
in standalone, stacking, or VLT mode to be 40 Gigabit Ethernet per second, perform the following:
Specify the uplink speed of the member interfaces in a LAG bundle for the Aggregator that operates
in standalone, stacking, or VLT mode to be 40 GbE. By default, the uplink speed of the LAG bundle is
set as 10 GbE. You cannot configure the uplink speed if the Aggregator operates in programmable
MUX mode. The stack-unit unit-number iom-mode [stack | standalone | vlt] 40G
command is available the CMC interface and the CLI interface.
CONFIGURATION
stack-unit unit-number iom-mode [stack | standalone | vlt] 40G
You can use the show system stack-unit unit-number iom-uplink-speed command to view
the uplink speed of the LAG bundles configured on the Flex IO modules installed on the Aggregator. The
value under the Boot-speed field in the output of the show command indicates the uplink speed that is
currently effective on the LAG bundles, whereas the value under the Next-Boot field indicates the uplink
speed that is applicable for the LAG bundle after the next reboot of the switch. Depending on the uplink
speed configured, the fan-out setting is designed accordingly during the booting of the switch.
The following example displays the output of the show system stack-unit unit-number iom-
uplink-speed command with the Boot-speed field contained in it:
Dell# show system stack-unit 0 iom-uplink-speed
Unit Boot-speed Next-Boot

stack-unit iom-mode uplink-speed
Specify the uplink speed of the member interfaces in a LAG bundle for the Aggregator that operates in
standalone, stacking, or VLT mode to be 40 GbE. By default, the uplink speed of the LAG bundle is set as
10 GbE.
Syntax
stack-unit unit-number iom-mode {stack | standalone | vlt}
uplink-speed 40G
To restore the default uplink speed of the LAG bundle, which is 10 GbE, use the
stack-unit unit-number iom-mode {stack | standalone | vlt}
command.
Parameters
unit number
<0-5>
Enter the number of the member stack unit. The range is
from 0 to 5.
