Compatibility Requirements

When you add an interface to a port channel group, Cisco NX-OS checks certain interface attributes to ensure
that the interface is compatible with the channel group. Cisco NX-OS also checks a number of operational
attributes for an interface before allowing that interface to participate in the port-channel aggregation.
The compatibility check includes the following operational attributes:
• Port mode
• Access VLAN
• Trunk native VLAN
• Allowed VLAN list
• Speed
• 802.3x flow control setting
• MTU
• Broadcast/Unicast/Multicast Storm Control setting
• Priority-Flow-Control
• Untagged CoS
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:
