FcoeApp Service


This chapter describes the DCNM web services' API methods for the FcoeApp service. This API is available for Cisco Nexus 7000 Series switches that run Cisco NX-OS Release 5.1(1) or later.

Information About FcoeApp Service

Fibre Channel over Ethernet (FCoE) is the mapping of Fibre Channel over selected full duplex IEEE 802.3 networks. The goal is to provide I/O consolidation over Ethernet to reduce network complexity in the data center. FCoE provides a method of transporting Fibre Channel traffic over a physical Ethernet connection. FCoE requires the underlying Ethernet to be full duplex and to provide lossless behavior for Fibre Channel traffic.

This interface defines all the APIs exposed by the FCoE feature service facade. APIs are defined with the following categories:

Query or Get APIs—Used to query data from the persisted database.

getVlansMappedToVsans

Returns the list of VLAN IDs that are mapped to the VSAN IDs passed.

ValidationException is thrown if any of the following situation occurs:

If the argument passed neInstanceNameIdCol is null or it is empty or if the element in the collection is not a valid network element InstanceNameId.

If the IDs in the vsans are out of valid Range.

Parameters

opContext—Operational context

neInstanceNameIdCol—collection of InstanceNameId of network elements which support FCoE

vsans—list of VSAN IDs.

Return Value

List of VLAN IDs mapped to the VSAN IDs in the FCoE enabled device.

getVsansMappedToVlans

Returns the list of VSAN IDs that are mapped to the VLAN IDs passed.

ValidationException is thrown if any of the following situation occurs:

If the argument passed neInstanceNameIdCol is null or it is empty or if the element in the collection is not a valid network element InstanceNameId.

If the IDs in the vsans are out of valid Range.

Parameters

opContext—Operational context

neInstanceNameIdCol—collection of InstanceNameId of network elements which support FCoE

vsans—list of VSAN IDs.

Return Value

List of list of VSAN IDs mapped to the VLAN IDs in the FCoE enabled device.
