Trunk configuration
Trunk groups can provide super-bandwidth connections between switches or other trunk capable
devices. A trunk is a group of ports that act together, combining their bandwidth to create a single,
larger port. Up to 12 trunk groups can be configured on the switch, with the following restrictions.
Any physical switch port can belong to no more than one trunk group.
Up to 6 ports/trunks can belong to the same trunk group.
All ports in a trunk must have the same configuration for speed, flow control, and auto negotiation.
Trunking from other devices must comply with Cisco® EtherChannel® technology.
