C H A P T E R 4 Configuring Switch Ports
If you do not explicitly select an algorithm, the port-based scheme
is used. However, the address-based algorithm has a more even
distribution and is the recommended choice.
Configuring Load Sharing
To set up the switch to load share among ports, you must create a
load-sharing group of ports. The first port in the load-sharing group
is configured to be the “master” logical port. This is the reference
port used in configuration commands. It can be thought of as the
logical port representing the entire port group.
The following rules apply to load sharing:
• A group can contain up to 8 ports.
• The ports in a group do not need to be contiguous.
To define a load-sharing group, you assign a group of ports to a
single, logical port number. To enable or disable a load-sharing
group, use the following commands:
enable sharing <port> grouping <portlist> {port-
based | address-based | round-robin}
disable sharing <port>
Load-Sharing Example
The following example defines a load-sharing group that contains
ports 9 through 12, and uses the first port in the group as the master
logical port 9:
enable sharing 9 grouping 9-12
In this example, logical port 9 represents physical ports 9
through 12.
When using load sharing, you should always reference the master
logical port of the load-sharing group (port 9 in the previous
example) when configuring or viewing VLANs. VLANs
configured to use other ports in the load-sharing group will have
those ports deleted from the VLAN when load sharing becomes
enabled.
Do not disable a port that is part of a load-sharing group. Disabling
the port prevents it from forwarding traffic, but still allows the link
to initialize. As a result, a partner switch does not receive a valid
