Removing an Aggregator from a Stack and Restoring Quad Mode
To remove an Aggregator from a stack and return the 40GbE stacking ports to 4x10GbE quad mode
follow the below steps:
1. Disconnect the stacking cables from the unit. The unit can be powered on or off and can be online
or offline.
2. Log on to the CLI and enter Global Configuration mode.

3. Configure the Aggregator to operate in standalone mode.

4. Log on to the CLI and reboot each switch, one after another, in as short a time as possible.
reload
EXEC PRIVILEGE
When the reload completes, the base-module ports comes up in 4x10GbE (quad) mode. The switch
functions in standalone mode but retains the running and startup configuration that was last
synchronized by the master switch while it operated as a stack unit.
Configuring the Uplink Speed of Interfaces as 40 Gigabit
Ethernet
You can configure the I/O Aggregator switch in standalone, VLT, and stack modes to operate with an
uplink speed of 40 Gigabit Ethernet per second. You can use the chassis management controller (CMC)
interface to access the switch and specify the 40 GbE QSFP+ module ports to function in 40 GbE mode
after the subsequent reload operation. By default, these QSFP+ modules function in 10GbE mode.
When you configure the native mode to be 40 GbE, the CMC sends a notification to the Aggregator to
set the default internal working of all of the ports to be 40 GbE after the switch reloads. After you set this
configuration, 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 for the uplink
speed to be effective.
This functionality to set the uplink speed is available from the CLI or the CMC interface when the
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 if the
Aggregator functions in programmable MUX mode with multiple uplink LAG interfaces or in stacking
mode. This is because CMC is not involved with the configuration of parameters when the Aggregator
operates in either of these modes, with the uplink interfaces being part of different LAG bundles.
