Guidelines for Creating Trunks
General Guidelines –
• Finish configuring port trunks before you connect the corresponding
network cables between switches to avoid creating a loop.
• A trunk can have up to eight ports.
• The ports at both ends of a connection must be configured as trunk
ports.
• All ports in a trunk must be configured in an identical manner,
including communication mode (i.e., speed, duplex mode and flow
control), VLAN assignments, and CoS settings.
