The GSS-24T2SFP web smart switch supports MAC-based trunking. This allows more than one port to be grouped together as a single link connection between two switch devices. This is also useful for switch-to-server and switch-to-router applications. The GSS-24T2SFP web smart switch allows four trunk groups that can accommodate up to eight trunk members in each group. A port in one trunk group cannot be a member of another trunk simultaneously. This feature provides redundancy and increases the effective bandwidth through a link. Traffic patterns are balanced between the ports within a trunk group by dynamically performing a MAC-based load balancing algorithm. This is supported only on point-to-point links with MACs operating in full duplex mode. All links in the same trunk group must operate at the same rate.
The GSS-24T2SFP web smart switch provides dynamic failover support within the trunk group. If a port within the trunk group fails, the other ports of the trunk group automatically assume the extra traffic load currently running through the link. Under normal operating modes, the links within the trunk group should have an equal amount of traffic. To achieve this, this switch performs load balancing based on a distribution algorithm.
The following parameters should be configured to enable this:
Distribution Criterion – Select a distribution algorithm from which the switch will perform load balancing:
¾SA (Source MAC Address)
¾DA (Destination MAC Address)
¾SA + DA (both SA and DA)
Member – the member port(s) of trunk group(s)
