The Generation1, Generation 2, and Generation 3 modules have the following restrictions for
PortChannel configuration:
• Generation 1 switching module interfaces do not support auto speed with a maximum of 2 Gbps.
Generation 1 and Generation 2 module interfaces do not support auto speed with maximum of 4
•
Gbps.
• Generation 2 and Generation 3 switching module interfaces cannot be forcefully added to a
PortChannel if sufficient resources are not available.
Note Before adding a Generation 2 or Generation 3 interface to a PortChannel, use the show port-resources
module command to check for resource availability.
When configuring PortChannels on switches with Generation 1, Generation 2, and Generation 3
switching modules, follow one of these procedures:
Configure the PortChannel, and then configure the Generation 2 and Generation 3 interfaces to auto
•
with a maximum of 2 Gbps.
Configure the Generation 1 switching modules followed by the Generation 2 switching modules,
•
and then the Generation 3 switching modules, and then configure the PortChannel.
When configuring PortChannels on switches with only Generation 2 and Generation 3 switching
modules, follow one of these procedures:
Configure the PortChannel, and then configure the Generation 3 interfaces to auto with a maximum
•
of 4 Gbps.
Configure the Generation 2 switching modules, followed by the Generation 3 switching modules,
•
and then configure the PortChannel.
