When using a port trunk, remember that:
• Ports can only be assigned to one trunk.
• The ports at both ends of a connection must be configured as trunk ports.
• The ports at both ends of a trunk must be configured in an identical manner,
including communication mode, and VLAN assignments.
• All the ports in a trunk have to be treated as a whole when moved from / to, added or
deleted from a VLAN.
• The Spanning Tree Algorithm will treat all the ports in a trunk as a whole.
• Enable the trunk prior to connecting any cable between the switches to avoid
creating a loop.
You can use the Port Trunking Configuration screen to set up port trunks as shown
