Fibre Channel over Ethernet for FC Flex IO Modules
FCoE provides a converged Ethernet network that allows the combination of storage-area network (SAN) and LAN traffic on a
Layer 2 link by encapsulating Fibre Channel data into Ethernet frames.
The Aggregator, installed with the FC Flex IO module, functions as a top-of-rack edge switch that supports converged
enhanced Ethernet (CEE) traffic — Fibre channel over Ethernet (FCoE) for storage, Interprocess Communication (IPC) for
servers, and Ethernet local area network (LAN) (IP cloud) for data — as well as FC links to one or more storage area network
(SAN) fabrics.
FCoE works with the Ethernet enhancements provided in Data Center Bridging (DCB) to support lossless (no-drop) SAN and
LAN traffic. In addition, DCB provides flexible bandwidth sharing for different traffic types, such as LAN and SAN, according to
802.1p priority classes of service. DCBx should be enabled on the system before the FIP snooping feature is enabled.
All of the commands that are supported for FCoE on the I/O Aggregator apply to the FC Flex IO modules. Similarly, all of the
configuration procedures and the settings that are applicable for FCoE on the I/O Aggregator are valid for the FC Flex IO
modules.
advertise dcbx-appln-tlv
On a DCBX port with a manual role, configure the application priority TLVs advertised on the interface to DCBX peers.
Syntax
advertise dcbx-appln-tlv {fcoe | iscsi}
To remove the application priority TLVs, use the no advertise dcbx-appln-tlv {fcoe |
iscsi} command.
Parameters
{fcoe | iscsi} Enter the application priority TLVs, where:
● fcoe: enables the advertisement of FCoE in application priority TLVs.
● iscsi: enables the advertisement of iSCSI in application priority TLVs.
Defaults Application priority TLVs are enabled to advertise FCoE and iSCSI.
Command Modes PROTOCOL LLDP
Supported Modes Programmable-Mux (PMUX)
