Guidelines for Creating Trunks
• Finish configuring port trunks before you connect the
corresponding network cables between switches to avoid
creating a loop.
• A trunk can contain up to eight 10/100 Mbps ports or up to two
1000 Mbps ports.
• The ports at both ends of a connection must be configured as
trunk ports.
• All ports in a trunk must consist of the same media type (i.e.,
twisted-pair or fiber).
• 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.
• All the ports in a trunk have to be treated as a whole when
moved from/to, added or deleted from a VLAN via the specified
port-channel.
• STP, VLAN, and IGMP settings can only be made for the entire
trunk via the specified port-channel.
