To associate a port with a port channel, use the channel-group Interface Configuration mode command.

To remove a port from a port channel, use the no form of this command.

Syntax

channel-group port channel mode {active | on | passive}

no channel-group

Parameters

port channel—The number of the port channel that the port will join.

mode—Specifies the mode of the port channel. The possible values are:

• active—Enables LACP unconditionally. It forces unconditionally the port to join a channel as a result of a LACP operation.

• on—Enables static only. It forces the port to join a channel without a LACP operation. In this mode, a usable EtherChannel exists only when both connected port groups are in the on mode.

• passive—Enables LACP only if a LACP device is detected. It forces the port to join a channel as a result of a LACP operation. Active mode places a port into a negotiating state in which the port initiates the negotiations with other ports by sending LACP packets. A channel is formed with another port group in either the active or passive mode.

Default Configuration

The port is not assigned to a port channel.

Command Mode

Interface Configuration (Ethernet) mode

Example

The following example forces gi1 to join the port channel 1 without a LACP operation:

switchxxxxxx(config)# interface gi1
switchxxxxxx(config-if)# channel-group 1 mode on

To configure the load-balancing policy for a port channel, use the port-channel load-balance Global Configuration mode command.

Syntax

port-channel load-balance {src-dst-mac | src-dst-mac-ip}

Parameters

src-dst-mac—Specifies that the port channel load-balancing is based on the source and destination MAC addresses for all packets.

src-dst-mac-ip—Specifies that the port channel load-balancing is based on the destination IP addresses, source IP addresses, destination MAC addresses, and source MAC addresses for all packets.

Default Configuration

The default option is src-dst-mac.

Command Mode

Global Configuration mode

User Guidelines

In the src-dst-mac-ip port channel load-balancing policy, fragmented packets may be reordered.

Example

switchxxxxxx(config)# port-channel load-balance src-dst-mac

To show information for all port channels, use the show etherchannel summary Privileged EXEC Mode command.

Syntax

show etherchannel summary

Parameters

N/A

Command Mode

Privileged EXEC Mode

Examples

switchxxxxxx# show etherchannel summary
