Static Link Aggregation Overview
Link aggregation allows you to combine physical connections into large virtual connections known as link
aggregation groups.
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 OmnniSwitch AOS software treats
these virtual links just like physical links. (See “Relationship to Other Features” on page 8-6 for more
information on how link aggregation interacts with other software features.)
Load balancing for Layer 2 non-IP packets is on a MAC address basis. However when IP packets are
transmitted, the balancing algorithm uses the IP address. Ports must be of the same speed within the same
link aggregate group.
The OmniSwitch implementation of link aggregation software allows you to configure the following two
different types of link aggregation groups:
• Static link aggregate groups
• Dynamic link aggregate groups
This chapter describes static link aggregation. For information on dynamic link aggregation, please refer
to Chapter 9, “Configuring Dynamic Link Aggregation.”
Static Link Aggregation Operation
Static link aggregate groups are virtual links between two nodes consisting multiple physical links.
Static aggregate groups can be created between OmniSwitch platforms.
The figure below shows a static aggregate group that has been configured between Switch A and Switch
B. The static aggregate group links four ports on a single NI on Switch A to two ports each on separate
NIs on Switch B. The network administrator has created a separate VLAN for this group so users can use
this high speed link.
Example of a Static Link Aggregate Group Network
See “Configuring Static Link Aggregation Groups” on page 8-6 for information on using Command Line
Interface (CLI) commands to configure static aggregate groups and see “Displaying Static Link
Aggregation Configuration and Statistics” on page 8-11 for information on using CLI to monitor static
aggregate groups.
Note. Static aggregate groups cannot be created between an OmniSwitch and some switches from other
vendors.
Switch A
Switch B
Switch software treats the
static aggregate groups as
one large virtual link.
