Usage Guidelines

The LACP system ID is the combination of the configurable LACP system priority value and the MAC address.

Each system that runs LACP has an LACP system priority value. You can accept the default value of 32768 for this parameter, or you can configure a value between 1 and 65535. LACP uses the system priority with the MAC address to form the system ID and also uses the system priority during negotiation with other devices. A higher system priority value means a lower priority.

The system ID is different for each virtual device context (VDC).

Examples

This example shows how to display the information about the LACP port channel for a specific port channel:

n1000v> show lacp system-identifier

Usage Guidelines

When you add an interface to a channel group, the software checks certain interface attributes to ensure that the interface is compatible with the channel group. For example, you cannot add a Layer 3 interface to a Layer 2 channel group. The software also checks a number of operational attributes for an interface before allowing that interface to participate in the port-channel aggregation.

This command displays the list of compatibility checks that the system uses.

Using the channel-group command, you can force ports with incompatible parameters to join the port channel as long as the following parameters are the same:

•(Link) speed capability

•Speed configuration

•Duplex capability

•Duplex configuration

•Flow-control capability

•Flow-control configuration

Note See the channel-group command for information about forcing ports to join a port channel.

Examples

This example shows how to display the list of compatibility checks that the system makes before an interface to a channel group:

n1000v# show port-channel compatibility-parameters

* port mode

Members must have the same port mode configured, either E or AUTO. If they

are configured in AUTO port mode, they have to negotiate E mode when they

come up. If a member negotiates a different mode, it will be suspended.

* speed

Members must have the same speed configured. If they are configured in AUTO

speed, they have to negotiate the same speed when they come up. If a member

negotiates a different speed, it will be suspended.

* MTU

Members have to have the same MTU configured. This only applies to ethernet

port-channel.

* MEDIUM

Members have to have the same medium type configured. This only applies to

ethernet port-channel.

* Span mode

Members must have the same span mode.

A channel-group interface can be in the following operational states:

•Down—The interface is down because it is administratively shut down or some other reason not related to port channels.

•Individual—The interface is part of a port channel but unable to aggregate into a port channel because of protocol exchange problems.

–This interface continues to forward traffic as an individual link.

–STP is aware of this interface.

•Suspended—The operational parameters of the interface are not compatible with the port channel. This interface is not forwarding traffic, although the physical MAC link state is still up.

•Switched—The interface is switched.

•Up (port channel)—The port channel is up.

•Up in port channel (members)—The port member of the port channel is up.

•Hot standby (LACP only)—The interface is eligible to join the port group if one of the interfaces currently participating in the LACP channel goes down.

–This interface does not forward data traffic, only protocol data units (PDUs).

–This interface does not run STP.

•Module-removed—The module has been removed.

•Routed—The interface is routed.
