What Is HPN-ICF-NPV-MIB?

HPN-ICF-NPV-MIB is a Hewlett-Packard (HP Networking, Comware/H3C-derived "ICF" MIB family) vendor-specific MIB that manages N-Port Virtualization (NPV) for Fibre Channel SAN edge switches operating within an NPV architecture. It models the load-balancing trigger for a VSAN via hpnicfNpvLoadbalanceVsan, per-interface/VSAN traffic mapping assignments in hpnicfNpvTrafficMapConfigTable (hpnicfNpvTrafficMapExternalIfIndexList, hpnicfNpvTrafficMapRowStatus, hpnicfNpvTrafficMapLastChange), and the external uplink interface actually assigned to each server-facing interface in hpnicfNpvServerIfTable (hpnicfNpvExternalIfIndex). This lets an operator confirm that NPV edge switches are correctly restricting or distributing traffic across specific uplinks to the NPV core switch, reducing Fibre Channel domain ID consumption in the SAN. It depends on HPN-ICF-FC-TC-MIB and HPN-ICF-VSAN-MIB for VSAN/FC textual conventions and IF-MIB for ifIndex, and administrators can download the HPN-ICF-NPV-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-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.

Supported Devices

HP Comware-based Fibre Channel SAN edge switches (NPV mode)

Monitoring Examples

An operator polls hpnicfNpvServerIfTable to see which hpnicfNpvExternalIfIndex a given server-facing FC port is currently using, and checks hpnicfNpvTrafficMapConfigTable's hpnicfNpvTrafficMapRowStatus for that VSAN; a server interface with no external interface assigned indicates none of its configured uplinks are currently valid, breaking connectivity to the fabric.

What Can Be Monitored

NPV load-balancing trigger per VSAN
traffic map external interface assignments
traffic map row status / last-change timestamp
server interface to external interface mapping

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpnicfNpv	1.3.6.1.4.1.11.2.14.11.15.2.127.6			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.

hpnicfNpvGlobalObjects	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.1
HPN hpnicfNpvLoadbalanceVsan	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.1.1	HpnicfFcVsanIndex	read-write	Used to trigger a load-banlancing in the specified VSAN (Virtual Storage Area Network). When the hpnicfNpvLoadbalanceVsan 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.
hpnicfNpvTrafficMapConfigTable	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.2		not-accessible	A table containing information on the assignment of traffic map interfaces to an interface.
hpnicfNpvTrafficMapConfigEntry	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.2.1		not-accessible	An entry in the hpnicfNpvTrafficMapConfigTable. 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 hpnicfNpvTrafficMapRowStatus object. Columnar objects can be modified when the corresponding hpnicfNpvTrafficMapRowStatus is 'active'.
HPN hpnicfNpvTrafficMapExternalIfIndexList	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.2.1.1	HpnicfNpvIfIndexList	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 hpnicfNpvTrafficMapConfigTable.
TIM hpnicfNpvTrafficMapLastChange	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.2.1.2	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 hpnicfNpvTrafficMapRowStatus	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.2.1.3	RowStatus	read-create	The status of this conceptual row. The row can be made 'active' only if value of corresponding instance of hpnicfNpvTrafficMapExternalIfIndexList is provided.
hpnicfNpvServerIfTable	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.3		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.
hpnicfNpvServerIfEntry	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.3.1		not-accessible	An entry in the hpnicfNpvServerIfTable, containing NPV related parameters established by a server interface indicated by ifIndex.
NUM hpnicfNpvExternalIfIndex	1.3.6.1.4.1.11.2.14.11.15.2.127.6.1.1.3.1.1	InterfaceIndex	read-only	This value of this object is the external interface assigned for the server interface associated with the server interface.
