FCoE examples in this chapter:
 FCoE is used on ports INT1 and .
CEE features are also used with LANs on ports INT2 and EXT5.

 All other ports are disabled or are connected to regular (non‐CEE) LAN devices.
In this example, the NE2552E acts as the central point for CEE configuration.
FCoE‐related ports will be configured for advertising CEE capabilities, but not to
accept external configuration. Other LAN ports that use CEE features will also be
configured to advertise feature settings to remote peers, but not to accept external
configuration. DCBX will be disabled on all non‐CEE ports.
This example can be configured using the following commands:
NE2552E(config)# cee enable
Note: Turning on CEE will automatically change some 802.1p QoS and 802.3x
standard flow control settings and menus (see "Turning CEE On or Off" on
page 246).
