Description: Manages Fibre Channel fabric login (FLOGIN/FLOGI) sessions and state on HP/Comware SAN 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 HPN-ICF-FC-FLOGIN-MIB?

HPN-ICF-FC-FLOGIN-MIB is an HP Networking (Comware/H3C) vendor MIB for Fibre Channel SAN switches, representing Fabric Login (FLOGI) session information for devices logging into an FC fabric. It exposes a table of login entries keyed by port identity, capturing the node and port World Wide Names (WWNs), assigned Fibre Channel ID, buffer-to-buffer credit values, and supported service class parameters negotiated at login. For hardware/software status monitoring, this MIB is central to verifying that end devices and storage targets have successfully and correctly logged into the fabric, since a missing or repeatedly re-established FLOGI entry for a known WWN indicates a flapping SAN link, HBA problem, or fabric instability. It is specific to Fibre Channel fabric concepts (FC-FS, FC-GS standards) rather than an extension of a common IETF MIB. It is deployed on HP/H3C Comware Fibre Channel or FCoE SAN switches used to interconnect servers and storage arrays. Engineers can download the HPN-ICF-FC-FLOGIN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-FC-FLOGIN-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 would poll hpnicfFcFLoginTable (via hpnicfFcFLoginIndex) and examine hpnicfFcFLoginPortWWN, hpnicfFcFLoginPortNodeWWN, and hpnicfFcFLoginPortFcId to confirm which storage initiators/targets are currently logged into the fabric and their assigned FC addresses. Comparing hpnicfFcFLoginRxBbCredit/hpnicfFcFLoginTxBbCredit against expected HBA capabilities can reveal a buffer-credit mismatch limiting throughput, and hpnicfFcFLoginSuppClassRequested shows which FC service class (e.g., Class 2 or 3) a device negotiated, with hpnicfFcFLoginClass2RxMTU/hpnicfFcFLoginClass3RxMTU exposing the negotiated frame size. A WWN disappearing from the table unexpectedly would indicate the corresponding SAN device has lost its fabric login.

What Can Be Monitored

logged-in device port/node WWN
assigned FC ID
RX/TX buffer-to-buffer credit
negotiated service class
class 2/3 receive MTU

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpnicfFcFLogin	1.3.6.1.4.1.11.2.14.11.15.2.127.3			This MIB module is for representing fabric login information.
hpnicfFcFLoginMibObjects	1.3.6.1.4.1.11.2.14.11.15.2.127.3.1
hpnicfFcFLoginTable	1.3.6.1.4.1.11.2.14.11.15.2.127.3.1.1		not-accessible	A table of Fibre Channel related service parameters used to represent the fabric login information in accord with each Nx_Port attached to a particular Fibre Channel port in a particular VSAN (Virtual Storage Area Network). Each entry is created by a fabric switch when an Nx_Port successfully logged in to it explicitly or implicitly, and is deleted when the port logged out.
hpnicfFcFLoginEntry	1.3.6.1.4.1.11.2.14.11.15.2.127.3.1.1.1		not-accessible	A group of Fibre Channel related service parameters used to represent fabric login information of a specific Nx_Port.
ADR hpnicfFcFLoginIndex	1.3.6.1.4.1.11.2.14.11.15.2.127.3.1.1.1.1	HpnicfFcAddressId	not-accessible	The index of current fabric login entry. The Fibre Channel address identifier is used to identify the associated Nx_Port of this entry.
