The MIB module for the management of N_port
Virtualization or NPV within the framework of Cisco's
N_port virtualization (NPV) Architecture.
N_Port virtualization reduces the number of Fibre
Channel domain IDs in SANs. Switches operating in the
NPV mode do not join a fabric; rather, they pass traffic
between NPV core switch links and end-devices, which
eliminates the domain IDs for these edge switches.
Glossary of terms Used in this MIB:
SAN - Storage Area Network
VSAN - Virtual Storage Area Network,
Similar to a VLAN.
NPV - N Port Virtualization, a technique
using which the number of domain IDs
in fibre channel fabric can be reduced,
leading to easier management.
When operating in this mode, a fibre
channel switch (typically,
a fabric/blade switch)
acts as a HBA with respect to the
fibre channel fabric and as a switch
with respect to the connected devices.
NPV Device - A fibre channel switch working in NPV
NPV Core Switch - A fibre channel edge switch connected to
one or more NPV devices.
Server - Host connected to the NPV device.
Typically, a Blade Server connected to
Blade switch in NPV mode in a Blade
Server Interface - Interface on the NPV Device that connects
to end devices(hosts/disks). Also, known
as F-port, as it operates in F port mode.
External Interface - Interface on the NPV Device that
connects to the NPV Core Switch.
Also known as NP-port as it operates
in NP port mode.
Traffic Map - Traffic map is a way to restrict traffic
flow from an interface to only a set of
interfaces. In NPV device, traffic map
can be used to present a server interface
to the fibre channel fabric only through
one of the valid external interfaces
specified in the set of interfaces.
