Version Description
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 congured to be member links in the same LAG
bundle. You cannot congure 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 conguration of parameters when the Aggregator operates in either of these modes with uplink interfaces
being part of dierent LAG bundles.
When you congure the native mode to be 40 GbE, the CMC sends a notication 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 congure
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 conguration of the uplink speed to be eective.
stack-unit priority
Congure 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 identier.
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.
Defaults 0
