GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches Link Aggregation Groups Link aggregation groups (LAGs), which are also known as port channels, allow you to combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the aggregation as if it were a single link, which increases fault tolerance and provides load sharing. You assign the LAG VLAN membership after you create a LAG. The LAG by default becomes a member of the default management VLAN (that is, VLAN 1). A LAG interface can be either static or dynamic, but not both. All members of a LAG must participate in the same protocols. A static port channel interface does not require a partner system to be able to aggregate its member ports. Static LAGs are supported. When a port is added to a LAG as a static member, it neither transmits nor receives LAGPDUs. The switch supports 26 LAGs. The LAGs menu contains the links described in the following sections. • LAG Configuration • LAG Membership • LACP Configuration • LACP Port Configuration LAG Configuration Use the LAG Configuration screen to group one or more full-duplex Ethernet links to be aggregated together to form a link aggregation group, which is also known as a port channel. The switch treats the LAG as if it were a single link.  To configure LAG settings: 1. Select Switching > LAG > Basic > LAG Configuration. 2. Select the check box next to the LAG to configure. You can select multiple LAGs to apply the same setting to the selected interfaces. Select the check box in the heading row to apply the same settings to all interfaces. 3. Configure or view the following settings: Note: Click current members in the list to see existing member ports in that LAG. • LAG Name. Specify the name you want assigned to the LAG. You can enter any string of up to 15 alphanumeric characters. A valid name has to be specified in order to create the LAG • Description. Specify the description string to be attached to a LAG. It can be up to 64 characters in length. Configuring Switching 83

Link Aggregation Groups

Link aggregation groups (LAGs), which are also known as port channels, allow you to

combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the

aggregation as if it were a single link, which increases fault tolerance and provides load

sharing. You assign the LAG VLAN membership after you create a LAG. The LAG by default

becomes a member of the default management VLAN (that is, VLAN 1).

A LAG interface can be either static or dynamic, but not both. All members of a LAG must

participate in the same protocols. A static port channel interface does not require a partner

system to be able to aggregate its member ports.

Static LAGs are supported. When a port is added to a LAG as a static member, it neither

transmits nor receives LAGPDUs. The switch supports 26 LAGs.

The LAGs menu contains the links described in the following sections.

LAG Configuration

Use the LAG Configuration screen to group one or more full-duplex Ethernet links to be

aggregated together to form a link aggregation group, which is also known as a port channel.
