ON Mode
When you add or modify a PortChannel member
port configuration, you must explicitly disable
(shut) and enable (no shut) the PortChannel
member ports at either end.
Port initialization is not synchronized.
All misconfigurations are not detected as no
protocol is exchanged.
Transitions misconfigured ports to the suspended
state. You must explicitly disable (shut) and
enable (no shut) the member ports at either end.
This is the default mode.
To configure active mode using Fabric Manager, follow these steps:
Step 1 Expand ISLs and then select Port Channels in the Physical Attributes pane.
You see the PortChannels configured in the Information pane.
Step 2 Click the Protocols tab and, from the Mode drop-down menu, select the appropriate mode for the Port
Channel.
Step 3 Click the Apply Changes icon to save any modifications.

About PortChannel Deletion

When you delete the PortChannel, the corresponding channel membership is also deleted. All interfaces
in the deleted PortChannel convert to individual physical links. After the PortChannel is removed,
regardless of the mode (ACTIVE and ON) used, the ports at either end are gracefully brought down,
indicating that no frames are lost when the interface is going down (see the
on page
If you delete the PortChannel for one port, then the individual ports within the deleted PortChannel
retain the compatibility parameter settings (speed, mode, port VSAN, allowed VSAN, and port security).
You can explicitly change those settings as required.

Deleting PortChannels

To delete a PortChannel using the PortChannel Wizard in Fabric Manager, follow these steps:

20-11).
If you use the default ON mode to avoid inconsistent states across switches and to maintain
consistency across switches, then the ports shut down. You must explicitly enable those ports again.
If you use the ACTIVE mode, then the PortChannel ports automatically recover from the deletion.
Chapter 23
ACTIVE Mode
When you add or modify a PortChannel interface,
the PortChannel automatically recovers.
There is synchronized startup of all ports in a
channel across peer switches.
Consistently detect misconfigurations using a
PortChannel protocol.
Transitions misconfigured ports to the isolated
state to correct the misconfiguration. Once you
correct the misconfiguration, the protocol ensures
automatic recovery.
You must explicitly configure this mode.
