Converged Enhanced Ethernet

BLADEOS 6.5.2 Application Guide

Converged Enhanced Ethernet (CEE) refers to a set of IEEE standards designed to allow different physical networks with different data handling requirements to be converged together, simplifying management, increasing efficiency and utilization, and leveraging legacy investments without sacrificing evolutionary growth.

CEE standards were developed primarily to enable Fibre Channel traffic to be carried over Ethernet networks. This required enhancing the existing Ethernet standards to make them lossless on a per-priority traffic basis, and to provide a mechanism to carry converged (LAN/SAN/IPC) traffic on a single physical link. Although CEE standards were designed with FCoE in mind, they are not limited to FCoE installations. CEE features can be utilized in traditional LAN (non-FCoE) networks to provide lossless guarantees on a per-priority basis, and to provide efficient bandwidth allocation based on application needs.

Turning CEE On or Off

By default on the G8124, CEE is turned off. To turn CEE on or off, use the following CLI commands:

RS G8124(config)# [no] cee enable

Caution—Turning CEE on will automatically change some 802.1p QoS and 802.3x standard flow

!control settings on the G8124. Read the following material carefully to determine whether you will need to take action to reconfigure expected settings.

It is recommended that you backup your configuration prior to turning CEE on. Viewing the file will allow you to manually re-create the equivalent configuration once CEE is turned on, and will also allow you to recover your prior configuration if you need to turn CEE off.

Effects on Link Layer Discovery Protocol

When CEE is turned on, Link Layer Discovery Protocol (LLDP) is automatically turned on and enabled for receiving and transmitting DCBX information. LLDP cannot be turned off while CEE is turned on.
