Licensing Requirements for FCoE

A unified fabric link carries both Ethernet and FCoE traffic.
Note
3 You must configure the CNAs and the blade switches as spanning-tree edge ports.
4 A blade switch must connect to exactly one Cisco Nexus 5000 Series converged access switch, preferably
over an EtherChannel, to avoid disruption due to STP reconvergence on events such as provisioning new
links or blade switches.
5 You must configure the Cisco Nexus 5000 Series converged access switch with a better STP priority than
the blade switches that are connected to it. This requirement allows you to create an island of FCoE VLANs
where the converged access switch is the spanning-tree root and all the blade switches connected to it
become downstream nodes.
6 Do not configure the FCoE VLANs as members of Ethernet links that are not designated to carry FCoE
traffic because you want to ensure that the scope of the STP for the FCoE VLANs is limited to UF links
only.
7 If the converged access switches and/or the blade switches need to be connected to each over Ethernet
links for the purposes of LAN alternate pathing, then such links must explicitly be configured to exclude
all FCoE VLANs from membership. This will ensure the scope of the spanning-tree protocol for FCoE
VLANs is limited to UF links only.
8 You must use separate FCoE VLANs for FCoE in SAN-A and SAN-B.
A remotelyconnected topology is supported only with Gen-2 (FIP) CNAs.
Note
Licensing Requirements for FCoE
On Cisco Nexus 5000 Series switches, FCoE capability is included in the Storage Protocol Services License.
Before using FCoE capabilities, you must ensure the following:
• The correct license is installed (N5010SS or N5020SS).
• You activated FCoE by entering the feature fcoe command in configuration mode.

Enabling FCoE

You can enable FCoE on the switch.
