to the same VLAN. Traffic between VLANs must be routed. LAN port VLAN membership is assigned

manually on a port-by-port basis.

vN_Port Virtual Node Port. vN_Ports are CNAs on node ports and FCoE storage ports.

vN_Port MAC

address

Virtual Node Port MAC address. vN_Port MAC address is the Name_Identifier of a vN_Port.

The MAC address used by an ENode for a particular address identifier during FC operation

using FCoE frames. Access Control List (ACL) is a persistent list, commonly composed of Access

Control Entries (ACEs) that enumerate the rights of principals (users and groups of users and/or

groups) to access resources.

vNP_Port Virtual N_Port Virtulization Port. vNP_Ports connect to vF_Ports and act as a proxy for other

N_Ports located on the NPV-enabled switch. The data forwarding component of an FC entity that

emulates an N_Port and is dynamically instantiated on successful completion of an FLOGI or

FDISC Exchange. The term virtual indicates the use of a non Fibre Channel link connecting a

VN_Port to a VF_Port.

zone set A set of zone definitions for a fabric. Zones in a zone set may overlap. For example, a port may

be a member of more than one zone. Fabric management may support switching between zone

sets to enforce different access restrictions, for example, at different times of day.

zoning A method of subdividing a storage area network into disjoint zones or subsets of nodes on the

network. Storage area network nodes outside a zone, except those with well-known addresses,

are invisible to nodes within the zone. Moreover, with switched SANs, traffic within each zone

may be physically isolated from traffic outside the zone.
