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.
iom-mode Denotes the operating mode of the I/O Aggregator.
stack Specify that the uplink speed of the member interfaces in a LAG bundle applies for
the Aggregator in stacking mode
standalone Specify that the uplink speed of the member interfaces in a LAG bundle applies for
the Aggregator in standalone mode
vlt Specify that the uplink speed of the member interfaces in a LAG bundle applies for
the Aggregator in VLT mode
uplink-speed 40G Set the uplink speed of the member or child interfaces of the LAG bundle to
function at 40 Gigabit Ethernet per second

9.3(0.0) Supported on the M I/O Aggregator
Usage
Information
This functionality to set the uplink speed is available from the CMC interface when the I/O Aggregator
functions as a simple MUX or a VLT node with all of the uplink interfaces configured to be member links in
the same LAG bundle. You cannot configure the uplink speed to be set as 40 GbE by default if the
Aggregator functions in programmable MUX mode with mutiple uplink LAG interfaces or in stacking mode
because CMC is not involved with configuration of parameters when the Aggregator operates in either of
these modes with uplink interfaces being part of different LAG bundles.
When you configure the native mode to be 40 GbE, the CMC sends a notification to the IOA to set the
default internal working of all of the ports to be 40 GbE after the reload of the switch is performed. After
you configure the native mode that denotes the uplink speed of the module ports to be 40 GbE, you must
enter the reboot command (not pressing the Reset button, which causes the factory default settings to
be applied when the device comes up online) from the CMC to cause the configuration of the uplink
speed to be effective.
stack-unit priority
Configure the ability of a switch to become the management unit of a stack.
Syntax
stack-unit stack-number priority 1-14
Parameters
stack-number Enter the stack member unit identifier.
1–14 This preference parameter allows you to specify the management priority of one
backup switch over another, with 0 the lowest priority and 14 the highest. The
switch with the highest priority value is chosen to become the management unit if
the active management unit fails or on the next reload.
