2.5 Trunk
The Ether-2416W web smart switch supports MAC-based trunking, which 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 Ether-2416W web smart switch
allows four trunk groups that can accommodate up to eight trunk members. 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. The traffic patterns can be more balanced between
the ports within a trunk group by dynamically performing the MAC-based algorithm. It is supported
only on point-to-point links with MACs operating full duplex mode. All links in the same trunk
group must operate at the same rate.
The Ether-2416W web smart switch provides dynamic failover when trunk is enabled. If a port of a
trunk group fails, the other ports of the trunk group assume traffics designated automatically for the
trunk. The links within the trunk group should have an equal amount of traffics. To achieve this, this
switch performs load balancing based on a distribution algorithm.
The following parameters are required to be set:
„
Distribution Criterion – choose distribution algorithm which switch performs load balancing
based on:
¾
SA (Source MAC Address)
¾ DA (Destination MAC Address)
¾ SA + DA (both SA and DA)
„ Member – the member port(s) of trunk group(s)
Select the Trunk menu on the web page to activate the page shown as below.
Because a trunk port can be aggregated by the member ports with the same configurations in most
functions for each other, there are some rules to limit the configurations of the trunking. The
following section will list the related rules for this function.
