Guidelines for Creating Aggregated Links

■Finish configuring aggregated links before you connect the corresponding network cables between switches to avoid creating a loop.

■An aggregated link can contain up to four up-link ports or up to two down-link ports.

■The ports at both ends of a connection must be configured as aggregated link ports.

■All ports in an aggregated link must be configured in an identical manner, including communication mode (that is, speed, duplex mode and flow control), VLAN assignments, and COS settings.

■All the ports in an aggregated link have to be treated as a whole when moved from or to, or added or deleted from a VLAN through the specified port-channel.

■STP, VLAN, and IGMP settings can only be made for the entire aggregated link through the specified port-channel.
