Static Link Aggregation Overview
Link aggregation allows you to combine 2, 4, or 8 physical connections into large virtual connections
known as link aggregation groups. You can configure up to 32 link aggregation groups per a standalone
switch or a stack of switches. Each group can consist of 2, 4, or 8 10-Mbps, 100-Mbps, 1-Gbps, or 10-
Gbps Ethernet links.

Gbps Ethernet links.
You can create Virtual LANs (VLANs), 802.1Q framing, configure Quality of Service (QoS) conditions,
and other networking features on link aggregation groups because the switch’s software treats these virtual
links just like physical links. (See

how link aggregation interacts with other software features.)
Load balancing for Layer 2 non-IP packets is on a MAC address basis and for IP packets the balancing
algorithm uses IP address as well. Ports must be of the same speed within the same link aggregate group.
algorithm uses IP address as well. Ports must be of the same speed within the same link aggregate group.
Alcatel-Lucent’s link aggregation software allows you to configure the following two different types of
link aggregation groups:
link aggregation groups:
• Static link aggregate groups
• Dynamic link aggregate groups

Static Link Aggregation Operation
Static link aggregate groups are virtual links between two nodes consisting of 2, 4, or 8 10-Mbps, 100-
Mbps, or 1-or 10-Gbps fixed physical links. You can configure up to 32 link aggregation groups per a
standalone switch or a stack of switches.

standalone switch or a stack of switches.
Static aggregate groups can be created between each of the following OmniSwitch products:
• two OmniSwitch 6400, 6800, 6850, 6855, or 9000 switches.
• an OmniSwitch 6400, 6800, 6850, 6855, or 9000 switch and an OmniSwitch 7700/7800, OmniSwitch
8800, or OmniSwitch 6600 Series switch.
• an OmniSwitch 6400, 6800, 6850, 6855, or 9000 switch and an early-generation Alcatel-Lucent
switch, such as an Omni Switch/Router.
Note. Static aggregate groups cannot be created between an OmniSwitch 6400, 6800, 6850, 6855, or 9000
