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 six 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.
By default, port 17 and port 18 are trunked to support an internal switch-to-switch crosslink trunk. By default,
ports 17 and 18 are disabled.
NOTE: See the N8406-023 1Gb Intelligent L3 Switch Application Guide for information on how to use
port trunks.
