This switch supports two modes of load balancing.
•
By MAC Addresses—(Default) Based on the destination and source MAC addresses of all
packets.
•
By IP and MAC Addresses—Based on the destination and source IP addresses for IP
packets, and destination and source MAC addresses for non-IP packets.
LAG Management
In general, a LAG is treated by the system as a single logical port. In particular, the LAG has port
attributes similar to a regular port, such as state and speed.
The device supports four LAGs. Each LAG has the following characteristics:
•
All ports in a LAG must be of the same media type.
•
To add a port to the LAG, it cannot belong to any VLAN except the default VLAN.
•
Ports in a LAG must not be assigned to another LAG.
•
No more than eight ports are assigned to a static LAG and no more than 16 ports can be
candidates for a dynamic LAG.
•
All the ports in a LAG must have auto-negotiation disabled, although the LAG can have
auto-negotiation enabled.
•
When a port is added to a LAG, the configuration of the LAG is applied to the port. When
the port is removed from the LAG, its original configuration is reapplied.
•
Protocols, such as Spanning Tree, consider all the ports in the LAG to be one port.
Default Settings and Configuration
Ports are not members of a LAG and are not candidates to become part of a LAG.
Static and Dynamic LAG Workflow
After a LAG has been manually created, LACP cannot be added or removed until the LAG is edited
and a member is removed. Only then the LACP field is activated.
•
To configure a static LAG:
1.
Disable LACP on the LAG to make it static. Assign up to eight member ports to the
static LAG in the Port List to the LAG Port Member list. Perform these actions in
the LAGs page.
2.
Configure various aspects of the LAG, such as speed and flow control by using the
Edit LAG page.
•
To configure a dynamic LAG:
1.
Enable LACP on the LAG. Assign up to 16 candidates ports to the dynamic LAG by
selecting and moving the ports from the Port List to the LAG Port Member List by
using the LAGs page.
2.
Configure various aspects of the LAG, such as speed and flow control by using the
LAGs page.
