Before Creating
Port Trunks
As mentioned in the above guidelines for creating port trunks, you need
to ensure the settings on your ports are identical before adding them to
a port trunk. To display your current port settings, see Displaying Port
Status on page 89. Then, to update the port configuration so all of the
ports in the trunk have the same configuration, see Configuring Port
Parameters on page 93. For information about changing port security,
see Configuring Port Security on page 105.
Load
Distribution
Methods
The AT-S60 management software provides the Source Address (SA)
Trunking load distribution method. When a switch receives a packet
from a network node, it examines the destination address to determine
on which port, if any, the packet should be transmitted. If the packet is
destined for a port trunk, the switch examines the source address of the
packet. If this is the first packet from the source node to be transmitted
over a port trunk, then the switch assigns the source address to a trunk
link. All subsequent packets from the source node are sent from the
assigned data link of the trunk.
The switch assigns source addresses so as to evenly distribute the
addresses, as much as possible, across all the ports of the trunk. The
intent is to ensure all the links in the trunk are used.
