Configuring Link Aggregation
Cisco Small Business 200 Series Smart Switch Administration Guide
The switch supports four LAGs.
Every 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 the original configuration of the LAG, the
configuration that existed for the port is no longer applied, and the
configuration of the LAG applies 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.
•
All the ports in the LAG must have the same 802. 1 p priority.
Static and Dynamic LAG Workflow
To configure a static LAG, perform the following actions:
1. Configure the selected LAG as a static LAG by disabling LACP on the LAG.
Assign up to eight active member ports to the static LAG by selecting and
moving the ports from the Port List to the LAG Members list by using the
Management Page
2. Configure the LAG speed and flow control by using the
To configure a dynamic LAG, perform the following actions:
1. Configure the selected LAG as a dynamic LAG by enabling 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 Members List by using the
Management Page
2. Configure the LAG speed and flow control by using the
3. Configure the LACP parameters of the ports in the LAG by using the
