Description: HH3C MIB for N-Port Virtualization (NPV) in Fibre Channel SANs, managing NPV mode on H3C storage switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is HH3C-NPV-MIB?

HH3C-NPV-MIB is an H3C proprietary MIB for N_Port Virtualization (NPV), a Fibre Channel SAN feature that lets an edge switch pass traffic to an NPV core switch without consuming its own FC domain ID. It exposes configuration and operational data about NPV-enabled server-facing ports, VSAN traffic-mapping, and load-balancing policy across external (uplink) interfaces. Monitoring this MIB reveals the software/configuration status of the NPV feature — whether a server interface's traffic map is correctly bound to external interfaces (hh3cNpvTrafficMapExternalIfIndexList), when that mapping last changed (hh3cNpvTrafficMapLastChange), and each entry's row status — which is critical for diagnosing SAN connectivity or failover problems rather than general hardware health. It builds on standard Fibre Channel/SAN concepts (VSANs, domain IDs) and typically coexists with FC-specific MIBs on multi-protocol H3C switches. It is deployed in storage-area networks where H3C FC switches operate in NPV edge mode beneath a core Fibre Channel director. Engineers can download the HH3C-NPV-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-NPV-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator could poll hh3cNpvTrafficMapConfigTable/hh3cNpvTrafficMapConfigEntry to see how server-facing ports (hh3cNpvServerIfTable) are load-balanced across external uplinks via hh3cNpvLoadbalanceVsan, and check hh3cNpvTrafficMapRowStatus to confirm each mapping entry is active. A sudden change reflected in hh3cNpvTrafficMapLastChange combined with a server interface losing its external interface list would indicate an uplink failure or reconfiguration event. This lets SAN operators detect NPV traffic-mapping problems before they cause storage path outages.

What Can Be Monitored

NPV traffic map configuration
server-facing to external interface mapping
VSAN load-balancing assignment
traffic map last-change timestamp
traffic map row status

OIDs

OID symbolic	OID numeric	Type	Access	Description
hh3cNpv	1.3.6.1.4.1.25506.2.127.6			This MIB module is for the management of N_Port Virtualization or NPV within the framework of N_Port virtualization(NPV) architecture. N_Port virtualization reduces the number of Fibre Channel domain IDs in SANs(Storage Aera Network). 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. NPV core switch is a fibre channel edge switch connected to one or more NPV devices.
hh3cNpvMibObjects	1.3.6.1.4.1.25506.2.127.6.1
hh3cNpvConfiguration	1.3.6.1.4.1.25506.2.127.6.1.1
hh3cNpvGlobalObjects	1.3.6.1.4.1.25506.2.127.6.1.1.1
HH3 hh3cNpvLoadbalanceVsan	1.3.6.1.4.1.25506.2.127.6.1.1.1.1	Hh3cFcVsanIndex	read-write	Used to trigger a load-banlancing in the specified VSAN (Virtual Storage Area Network). When the hh3cNpvLoadbalanceVsan is set to a specific VSAN, a disruptive load-balancing process will be initiated in the VSAN so that all nodes in the VSAN will re-login to the core switch. This load-balancing process redistributes downlink traffic across all uplink interfaces for better load balancing, but it causes traffic interruption.
hh3cNpvTrafficMapConfigTable	1.3.6.1.4.1.25506.2.127.6.1.1.2		not-accessible	A table containing information on the assignment of traffic map interfaces to an interface.
hh3cNpvTrafficMapConfigEntry	1.3.6.1.4.1.25506.2.127.6.1.1.2.1		not-accessible	An entry in the hh3cNpvTrafficMapConfigTable. This table contains entries for each of the interfaces which has been assigned a set of interfaces for traffic mapping in the VSAN. Traffic mapping is a technique used in NPV device to restrict the usage of external interface(s) for forwarding the traffic from server interface to the fibre channel fabric. If an interface comes up as a server interface and finds a corresponding entry in this table, then the switch software will assign a valid external interface from this list, if any. Once assigned, that assigned external interface will be used for forwarding the traffic from the server interface to the fibre channel fabric. If an interface comes up as a server interface and finds an entry in this table, but with no valid list of external interfaces, then the switch software keeps the server interface in operationally down state until at least one of the interface in the list becomes a valid external interface. If an interface comes up as a server interface and it can not find an entry in this table, then any of the available external interfaces can be assigned to that server interface. Entries in this table can be created or destroyed via hh3cNpvTrafficMapRowStatus object. Columnar objects can be modified when the corresponding hh3cNpvTrafficMapRowStatus is 'active'.
HH3 hh3cNpvTrafficMapExternalIfIndexList	1.3.6.1.4.1.25506.2.127.6.1.1.2.1.1	Hh3cNpvIfIndexList	read-create	The list of external interfaces which the traffic needs to be mapped to. This object is a list of interfaces presented as an octet string of interface indices or ifindex-es. The list should contain at least one interface and at most all the interfaces in the switch up to 16384 interfaces. The 16384 interfaces max-limit is due to the size of this object. Specifying this object is mandatory for the creation of a row in hh3cNpvTrafficMapConfigTable.
TIM hh3cNpvTrafficMapLastChange	1.3.6.1.4.1.25506.2.127.6.1.1.2.1.2	TimeStamp	read-only	The value of sysUpTime at the time of the latest change to this traffic map entry. When there has not been any change to the traffic map entry, the value of this field will be that of the entry creation time.
ROW hh3cNpvTrafficMapRowStatus	1.3.6.1.4.1.25506.2.127.6.1.1.2.1.3	RowStatus	read-create	The status of this conceptual row. The row can be made 'active' only if value of corresponding instance of hh3cNpvTrafficMapExternalIfIndexList is provided.
hh3cNpvServerIfTable	1.3.6.1.4.1.25506.2.127.6.1.1.3		not-accessible	This table contains, one entry for each server interface(FC-port configured in F-port mode) in this VSAN in the Fabric element. Each entry contains NPV related information like external interface assigned for the server interface in the VSAN.
hh3cNpvServerIfEntry	1.3.6.1.4.1.25506.2.127.6.1.1.3.1		not-accessible	An entry in the hh3cNpvServerIfTable, containing NPV related parameters established by a server interface indicated by ifIndex.
NUM hh3cNpvExternalIfIndex	1.3.6.1.4.1.25506.2.127.6.1.1.3.1.1	InterfaceIndex	read-only	This value of this object is the external interface assigned for the server interface associated with the server interface.
