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 management VLAN.
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 LACPDUs. ProSafe® Managed Switches support up to 64 LAGs.
From the LAGs link, you can access the following pages:
•

LAG Configuration

• LAG Membership
LAG Configuration
Use the LAG (Port Channel) Configuration page 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 access the LAG Configuration page, click Switching
To configure LAG settings:
1. Use LAG Name to enter the name you want assigned to the LAG. You may enter any
string of up to 15 alphanumeric characters. A valid name has to be specified in order to
create the LAG.
2. Use Hash Mode to select the load-balancing mode used on a port-channel (LAG). Traffic is
balanced on a port-channel (LAG) by selecting one of the links in the channel over which to
transmit specific packets. The link is selected by creating a binary pattern from selected
fields in a packet, and associating that pattern with a particular link:
• Src MAC,VLAN,EType,incoming port - Source MAC, VLAN, EtherType, and
incoming port associated with the packet.
