Aggregating Ports

Link Aggregation optimizes port usage by linking a group of ports together to form a single trunk. Aggregating

ports multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy. The

device supports both static trunks and Link Aggregation Control Protocol (LACP) trunks. LACP trunks negotiate

aggregating port links with other LACP ports located on a different device. If the other device ports are also LACP

ports, the devices establish a trunk between them.

Ensure the following:

• All ports within a trunk must be the same media type.

• A VLAN is not configured on the port.

• The port is not assigned to a different trunk.

• Auto-negotiation mode is not configured on the port.

• The port is in full-duplex mode.

• All ports in the trunk have the same ingress filtering and tagged modes.

• All ports in the trunk have the same back pressure and flow control modes.

• All ports in the trunk have the same priority.

• All ports in the trunk have the same transceiver type.

• The device supports up to eight trunks, and eight ports in each trunk.

• Ports can be configured as LACP ports only if the ports are not part of a previously configured trunk.

• Ports added to a trunk lose their individual port configuration. When ports are removed from the trunk, the

original port configuration is applied to the ports.

This section contains the following procedures for configuring static port trunks on the device.

• Defining Trunk Settings

• Defining Port Trunking

• Configuring LACP

Defining Trunk Settings

The Trunk Settings Page contains parameters for defining Trunks.

To define a port trunk:

1. Click Layer 1 > Trunk Settings. The Trunk Settings Page opens:

1 2 ... 77 78 79 80 81 82 83 84 85 86 87 ... 204 205
