Extreme Networks Summit 200-24 - Configuring Switch Load Sharing

Load Sharing on the Switch
Summit 200 Series Switch Installation and User Guide 81
The address-based load-sharing algorithm uses addressing information to determine which physical
port in the load-sharing group to use for forwarding traffic out of the switch. Addressing information is
based on the packet protocol, as follows:
— IP packets—Use the source and destination MAC and IP addresses.
— All other packets—Use the source and destination MAC address.
Configured IP Address-Based Load Sharing
When you configure load sharing, the switch examines a specific place in the packet to determine which
egress port to use for forwarding traffic:
• For Layer 2 load sharing, the switch uses the MAC source address, MAC destination address, IP
source address, and IP destination address.
• For Layer 3 load sharing, the switch uses the IP destination address.
You can control the field examined by the switch for IP address-based load sharing, using the following
command:
config sharing address-based [mac_source | mac_destination | mac_source_destination |
ip_source | ip_destination | ip_source_destination]
where:
This feature is available for the address-based load-sharing algorithm, only.
To verify your configuration, use the following command:
show sharing address-based
Configuring Switch Load Sharing
To set up a 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 as 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.
mac_source
Indicates that the switch should examine the MAC source
address.
mac_destination
Indicates that the switch should examine the MAC
destination address.
mac_source_destination
Indicates that the switch should examine the MAC source
and destination address.
ip_source
Indicates that the switch should examine the IP source
address.
ip_source_destination
Indicates that the switch should examine the IP source
address and destination address.
ip_destination
Indicates that the switch should examine the IP
destination address.
