Trunk
6.1 Introduction
“Trunking” means aggregating multiple low-speed physical links onto a single higher-speed logical link. For
example, two Fast Ethernet (100Mbps) links could be aggregated into one single 200Mbps link.
Trunking is an advanced feature of the PES-1014. Exercise extreme caution if you decide to configure
these menus.
Configure up to four trunks with two to four ports in each trunk. The last number of the trunk set must be port 2, 6,
10, or 14. Within each trunk set, you may freely gather two to four ports into one trunk. For example, you cannot
group ports 2 and 3 to form a trunk, because they are not in the same trunk set; but you can use ports 3, 4 and 6 to
form a trunk.
Ethernet port A is trunk port A and RJ 11 port 1 is trunk port 1.
6.2 Load-balancing Methods
There are two load-balancing methods for aggregating ports onto a trunk.
6.2.1 MAC-based Load-balancing
You can only use this method of you are aggregating the maximum of four ports into one trunk. It determines
which port to forward an incoming packet to by examining two bits (that you designate) of its source MAC address
and destination MAC address.
6.2.2 Port-based Load-balancing
Using this method, you have to determine which trunk port to link with a non-trunk port so that the load is balanced
among all trunk ports.
6.3 Trunk Menus
