Configuring Port Channels
Use the show port-channel compatibility-parameters command to see the full list of compatibility checks
that Cisco NX-OS uses.
You can only add interfaces configured with the channel mode set to on to static port channels. You can also
only add interfaces configured with the channel mode as active or passive to port channels that are running
LACP. You can configure these attributes on an individual member port.
When the interface joins a port channel, the following individual parameters are replaced with the values on
the port channel:
• Bandwidth
• MAC address
• Spanning Tree Protocol
The following interface parameters remain unaffected when the interface joins a port channel:
• Description
• CDP
• LACP port priority
• Debounce

configuration for the interface:
• When an interface joins or leaves a port channel, the following parameters remain unaffected:
• QoS
• Bandwidth
• Delay
• STP
• Service policy
• ACLs
• Beacon
• Description
• CDP
• LACP port priority
• Debounce
