About PortChannel Configuration

Before configuring a PortChannel, consider the following guidelines:
•
•
On switches with Generation 1 switching modules, or a combination of Generation 1 and Generation 2
Note
switching modules, you can configure a maximum of 128 PortChannels. On switches with only
Generation 2 switching modules, you can configure a maximum of 256 PortChannels.
If you misconfigure PortChannels, you may receive a misconfiguration message. If you receive this
message, the PortChannel's physical links are disabled because an error has been detected.
A PortChannel error is detected if the following requirements are not met:
•
•
•
If all three conditions are not met, the faulty link is disabled.

Configuring PortChannels

To create a PortChannel using the PortChannel Wizard in Fabric Manager, follow these steps:
Step 1 Click the PortChannel Wizard icon in the toolbar (see
Figure 23-8

Configure the PortChannel across switching modules to prevent redundancy on switching module
reboots or upgrades.
Ensure that one PortChannel is not connected to different sets of switches. PortChannels require
point-to-point connections between the same set of switches.
Each switch on either side of a PortChannel must be connected to the same number of interfaces.
Each interface must be connected to a corresponding interface on the other side (see
an example of an invalid configuration).
Links in a PortChannel cannot be changed after the PortChannel is configured. If you change the
links after the PortChannel is configured, be sure to reconnect the links to interfaces within the
PortChannel and reenable the links.
