Description: HH3C MIB for SAN aggregation managing Fibre Channel SAN aggregation and inter-switch links 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-SAN-AGG-MIB?

HH3C-SAN-AGG-MIB manages Storage Area Network (SAN) aggregation groups on H3C Fibre Channel storage switches, allowing multiple FC ports to be bundled into a single logical inter-switch link for higher bandwidth and redundancy. It exposes aggregation group creation/membership, per-member port state, and negotiated link speed data (both previous and current). Its monitoring role centers on link/hardware health for storage fabrics: tracking member port state lists and speed changes reveals a degraded or dropped FC link within an aggregation group, which could reduce SAN throughput or redundancy without an outright outage. It is a vendor-specific extension built on top of Fibre Channel switching concepts and typically coexists with standard FC management frameworks (e.g., FC-MGMT/FICON-related MIBs) rather than replacing them. It is deployed on H3C Fibre Channel or FCoE storage switches used to interconnect SAN fabrics in data center storage networks. Engineers can download the HH3C-SAN-AGG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-SAN-AGG-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

H3C Fibre Channel/FCoE storage switch

Monitoring Examples

An administrator would poll hh3cSanAggGroupTable for hh3cSanAggMemberStateList against a given hh3cSanAggGroupIndex to confirm all FC ports in the aggregation are up, and compare hh3cSanAggGroupPreviousSpeed to hh3cSanAggGroupCurrentSpeed to detect an unexpected link-speed renegotiation. A member port reported down in hh3cSanAggMemberStateList while hh3cSanAggMaxMemberNumber is otherwise fully subscribed would signal reduced SAN aggregate bandwidth needing attention.

What Can Be Monitored

SAN aggregation group membership
per-member FC port state
current vs previous link speed
aggregation group row status

OIDs

OID symbolic	OID numeric	Type	Access	Description
hh3cSanAgg	1.3.6.1.4.1.25506.2.127.2			This MIB module is for configuring and monitoring SAN (Storage Area Networks) aggregation group related MIB objects. This MIB can be used to add or delete a SAN aggregation group, and make one or more FC (Fiber Channel) ports join or leave the group, as well as show their states.
hh3cSanAggMibObjects	1.3.6.1.4.1.25506.2.127.2.1
I32 hh3cSanAggMaxMemberNumber	1.3.6.1.4.1.25506.2.127.2.1.1	Integer32	read-only	This value specifies the maximum member number that a SAN aggregation group supports, and this restriction depends on product customization.
hh3cSanAggGroupTable	1.3.6.1.4.1.25506.2.127.2.2		not-accessible	A table of SAN aggregation objects to be used in configuring and monitoring a SAN aggregation group and its members.
hh3cSanAggGroupEntry	1.3.6.1.4.1.25506.2.127.2.2.1		not-accessible	A group of SAN aggregation objects to be used in configuring and monitoring a SAN aggregation group and its members.
I32 hh3cSanAggGroupNumber	1.3.6.1.4.1.25506.2.127.2.2.1.1	Integer32	accessible-for-notify	The serial number of the current SAN aggregation group.
I32 hh3cSanAggGroupIndex	1.3.6.1.4.1.25506.2.127.2.2.1.2	Integer32	read-only	The ifIndex of the current SAN aggregation group.
HH3 hh3cSanAggMemberList	1.3.6.1.4.1.25506.2.127.2.2.1.3	Hh3cMemberList	read-create	List of member's ifIndex in the current SAN aggregation group. If there is no member in the SAN aggregation group, the list length should be zero. Otherwise each member's ifIndex value occupies 4 octets. The greatest length of this list depends on the maximum number of members a SAN aggregation group supports, which can be customized and therefore is not a fixed value. When getting the group members' ifIndexes, the result was sorted in ascending order of ifIndex values. However, when setting the group members' ifIndexes, the sequence of ifIndex values is not required.
HH3 hh3cSanAggMemberStateList	1.3.6.1.4.1.25506.2.127.2.2.1.4	Hh3cMemberList	read-only	List of member's state in current SAN aggregation group, where the state value is sorted in ascending order of member's ifIndex, which is consistent with the 'get' result of 'hh3cSanAggMemberList'. The explanation of this value's length is as same as the 'hh3cSanAggMemberList'. Each member's state value occupies 4 octets. The value specifications are listed as follows: 1: This member hasn't passed the link negotiation. 2: This member has passed the link negotiation but has not been selected. 3: This member has been selected.
ROW hh3cSanAggGroupRowStatus	1.3.6.1.4.1.25506.2.127.2.2.1.5	RowStatus	read-create	RowStatus. Now only three states are supported: createAndGo, active, and destroy.
hh3cSanAggObjForNotification	1.3.6.1.4.1.25506.2.127.2.3
I32 hh3cSanAggGroupPreviousSpeed	1.3.6.1.4.1.25506.2.127.2.3.1	Integer32	accessible-for-notify	The previous speed of the SAN aggregation group.
I32 hh3cSanAggGroupCurrentSpeed	1.3.6.1.4.1.25506.2.127.2.3.2	Integer32	accessible-for-notify	The current speed of the SAN aggregation group.
hh3cSanAggNotifications	1.3.6.1.4.1.25506.2.127.2.4
hh3cSanAggNotificationPrefix	1.3.6.1.4.1.25506.2.127.2.4.0
NTF hh3cSanAggGroupSpeedChange	1.3.6.1.4.1.25506.2.127.2.4.0.1			This event will be triggered whenever a SAN aggregation group changes its speed.
NTF hh3cSanAggMemberInactive	1.3.6.1.4.1.25506.2.127.2.4.0.2			This event will be triggered whenever any member in a SAN aggregation group is made inactive.
NTF hh3cSanAggMemberActive	1.3.6.1.4.1.25506.2.127.2.4.0.3			This event will be triggered whenever any member in a SAN aggregation group is made active.
