Using ATX Trunking

802.1D Spanning Tree takes about 30 seconds to resolve which ATX ports in a trunk group are to become forwarding ports. As ports within a trunk group become forwarding ports, traffic within the trunk group will be momentarily halted to guarantee the first-in, first-out ordering of Ethernet packets.

NOTE

Connections between ATX switches must be point-to-point; there cannot be any other devices on those segments. The ATX ports used for trunking can be in any order. Remember, though, that the switches on both ends of the connections must have trunking enabled for their ports which are used for the connections.

Trunking can only be disabled for one port at a time. To disable trunking for your ATX ports using the Trunking Table window:

1.In the port selection area, click on the selection button representing the port for which you would like to disable trunking.

2.Click on Disable. The trunking table will update to reflect the new trunking selections.

3.If you are disabling trunking for more than one port, click on Clear to clear your previous selection in the port selection area.

4.Repeat steps 1-3 for any other ports for which you would like to disable trunking.
