When detecting a loop between two interfaces, the system takes the following actions on the looped
interface:
• If the looped interface is an access interface: perform the configured protective action, send traps
to the terminals, and delete all MAC address entries of the interface.
• If the looped interface is a trunk or hybrid interface: send traps to the terminals. If loopback
detection control is enabled, perform the configured protection action on the looped interface, and
delete all MAC address entries of the interface.
