Hierarchy Level

Original CLI

ELS CLI for Platforms that Support FCoE


The no-fcoe-trusted configuration statement is in a different hierarchy on the original CLI than on the Enhanced Layer 2 Software (ELS) CLI.


Configure the specified 10-Gigabit Ethernet interface not to trust Fibre Channel over Ethernet (FCoE) traffic. If an interface is directly connected to an FCoE device, the interface should not be configured as an FCoE trusted interface. If an interface that you want to connect to an FCoE device has been configured as an FCoE trusted interface, use the no-fcoe-trusted statement to convert the interface to an untrusted interface. Untrusted interfaces can perform FIP snooping to provide access security for FCoE traffic.

However, if an interface is connected to another switch such as an FCoE forwarder (FCF) or a transit switch, you can configure the interface as trusted so that the interface forwards FCoE traffic from the switch to the FCoE devices without installing FIP snooping filters.
