46CHAPTER 2: PORT CONFIGURATION

A load sharing aggregation group may contain several selected ports, but a non-load sharing aggregation group can only have one selected port, while others as standby ports. Selection criteria of selected ports vary for different types of aggregation groups.

Configuring Link The Switch 7750 only supports LACP for ports on the same I/O module. A Aggregation maximum number of 16 ports can be active in a link aggregation. For modules

that have fewer than 16 ports, such as the 8-port 1000BASE-X-GE module, only eight ports can be active members of a link aggregation.

Link aggregation configuration includes tasks described in the following sections:

■Enabling or Disabling LACP at a Port

■Creating or Deleting an Aggregation Group

■Adding or Deleting Ethernet Ports to or from an Aggregation Group

■Setting or Deleting an Aggregation Group Descriptor

■Configuring System Priority

■Configuring Port Priority

■Displaying and Debugging Link Aggregation

Enabling or Disabling LACP at a Port

You should first enable LACP at the ports before performing dynamic aggregation, so that both parties can agree on adding/deleting the ports into/from a dynamic LACP aggregation group.

Perform the following configuration in Ethernet port view.

Table 39 Enabling/Disabling LACP at a Port

Operation	Command
Enable LACP at the port	lacp enable
Disable LACP at the port	undo lacp enable

LACP is disabled at the port by default.

Note that:

■You cannot enable LACP at a

■Mirrored port

■Port with a static MAC address configured

■Port with static ARP configured

■Port with 802.1x enabled.

■You cannot enable LACP on a port in a manual aggregation group.

■You can add a port with LACP enabled to a manual aggregation group, but the LACP will be disabled on it automatically. However, you can add a port with LACP disabled into a static LACP aggregation group, and the LACP will be enabled automatically.
