Cisco Nexus 5000 Series Interfaces Command Reference - Cisco Nexus 5000 Series Command Reference Manual

channel-group (Ethernet)
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 for static EtherChannels, that is,
without a configured aggregation protocol. You can only add interfaces configured with the channel mode as
active or passive to EtherChannels that are running LACP.
You can configure these attributes on an individual member port. If you configure a member port with an
incompatible attribute, Cisco NX-OS suspends that port in the EtherChannel.
When the interface joins an EtherChannel, some of its individual parameters are overridden with the values
on the EtherChannel, as follows:
• MAC address
• Spanning Tree Protocol (STP)
• Service policy
• Quality of service (QoS)
• Access control lists (ACLs)
Interface parameters, such as the following, remain unaffected when the interface joins or leaves a EtherChannel:
• Description
• Cisco Discovery Protocol (CDP)
• LACP port priority
• Debounce
• Rate mode
• Shutdown
• SNMP trap
If interfaces are configured for the EtherChannel interface and a member port is removed from the EtherChannel,
the configuration of the EtherChannel interface is not propagated to the member ports.
Any configuration changes that you make in any of the compatibility parameters to the EtherChannel interface
are propagated to all interfaces within the same channel group as the EtherChannel (for example, configuration
changes are also propagated to the physical interfaces that are not part of the EtherChannel but are part of the
channel group).
Examples This example shows how to add an interface to LACP channel group 5 in active mode:
switch(config)# interface ethernet 1/1
switch(config-if)# channel-group 5 mode active
switch(config-if)#
This example shows how to forcefully add an interface to the channel group 5:
switch(config)# interface ethernet 1/1
switch(config-if)# channel-group 5 force
switch(config-if)#
