Description: Handles the H3C/3Com Rapid Ring Protection Protocol (RRPP), a vendor-proprietary protocol delivering fast recovery for ring-topology Ethernet LAN redundancy.

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 A3COM-HUAWEI-RRPP-MIB?

A3COM-HUAWEI-RRPP-MIB is a joint 3Com/H3C (Huawei-3Com) vendor MIB managing the Rapid Ring Protection Protocol (RRPP), a proprietary alternative to Spanning Tree that provides sub-second failover for Ethernet switches wired in a ring topology. It exposes ring-domain configuration (domain ID, control VLAN, hello/fail timers, protected VLAN instance lists), global RRPP enable state and authentication password settings, and per-ring status/notification objects. Its monitoring value is chiefly software/protocol status and fault detection: h3cRrppEnableStatus and per-domain h3cRrppDomainHelloTime/h3cRrppDomainFailTime reveal whether ring protection is active and correctly timed, while h3cRrppNotifications alert on ring breaks or topology changes that RRPP is recovering from. The module description explicitly frames RRPP as functionally comparable to Spanning Tree Protocol, indicating a conceptual (though not structural) relationship to the IETF Bridge/STP MIBs. It is deployed on H3C/3Com/Huawei enterprise and campus switches wired in Ethernet ring topologies for fast link-failure recovery. Engineers can download the A3COM-HUAWEI-RRPP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-RRPP-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/3Com/Huawei-3Com Ethernet switch (ring topology)

Monitoring Examples

An operator would poll h3cRrppEnableStatus and h3cRrppDomainTable/h3cRrppDomainEntry rows keyed by h3cRrppDomainID to confirm ring protection is enabled and that h3cRrppDomainControlVlanID matches the intended control VLAN. Checking h3cRrppDomainHelloTime against h3cRrppDomainFailTime would reveal a timer misconfiguration that could delay failover detection. Subscribing to h3cRrppNotifications would alert the NMS when a ring link break or master-node role change occurs, and h3cRrppDomainRowStatus would confirm whether a given ring domain's configuration row is active.

What Can Be Monitored

RRPP enable status
ring domain configuration (control VLAN, hello/fail timers)
protected VLAN instance list
ring break / topology change notifications
domain row status

How to Use in IPNetwork Monitor

Example using h3cRrppPortRXError OID:

Select an H3C/3Com Ethernet ring switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type h3cRrppPortRXError into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The statistics of illegal RRPP packets received from this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
h3cRrpp	1.3.6.1.4.1.43.45.1.10.2.45			The RRPP (Rapid Ring Protection protocol) provides fast protection switching to layer 2 switches interconnected in an Ethernet ring topology. When a link in the ring breaks, the RRPP can recover the data path quickly. Its protection switching is similar to what can be achieved with the Spanning Tree Protocol (STP), but the converging time is less than a second after link failure. This MIB defines management information used on products which support RRPP.
h3cRrppScalarGroup	1.3.6.1.4.1.43.45.1.10.2.45.1
ENA h3cRrppEnableStatus	1.3.6.1.4.1.43.45.1.10.2.45.1.1	EnabledStatus	read-write	Indicating whether the RRPP is enabled on this switch.
OCT h3cRrppPassword	1.3.6.1.4.1.43.45.1.10.2.45.1.2	OCTET STRING	read-write	Password configured for RRPP nodes to identify the validity of a link-down message. This value must be set together with h3cRrppPasswordType which indicates whether this value can be got. This value can not be set alone without configuring h3cRrppPasswordType.
INT h3cRrppPasswordType	1.3.6.1.4.1.43.45.1.10.2.45.1.3	INTEGER	read-write	Indicating whether the h3cRrppPassword can be got. simple(1):h3cRrppPassword can be got. cipher(2):h3cRrppPassword can not be got. This value can not be set alone without configuring h3cRrppPassword.
INT h3cRrppProtectVlanConfigMode	1.3.6.1.4.1.43.45.1.10.2.45.1.4	INTEGER	read-only	Indicating the mode in which the protected VLANs of an RRPP domain are configured. The value 'vlan' indicates that h3cRrppDomainProtectVlanListLow and h3cRrppDomainProtectVlanListHigh can be used for setting protected VLANs, while h3cRrppDomainInstanceListLow and h3cRrppDomainInstanceListHigh cannot. By contraries, the value 'instance' indicates that 3cRrppDomainInstanceListLow and h3cRrppDomainInstanceListHigh can be used for setting protected VLANs while the other two cannot.

Within each octet, the most significant bit represents the highest numbered instance, and the least significant bit represents the lowest numbered instance. Thus, each instance to which the protected VLANs of an RRPP domain are mapped corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the VLANs mapped to the instance are protected VLANs of the RRPP domain. By contraries, the VLANs mapped to the instance are not protected VLANs if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainInstanceListHigh at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'instance'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.

Within each octet, the most significant bit represents the highest numbered instance, and the least significant bit represents the lowest numbered instance. The most significant bit of the last octet is invalid. Thus, each instance to which the protected VLANs of an RRPP domain are mapped corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the VLANs mapped to the instance are protected VLANs of the RRPP domain. By contraries, the VLANs mapped to the instance are not protected VLANs if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainInstanceListLow at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'instance'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.

Within each octet, the most significant bit represents the highest numbered VLAN, and the least significant bit represents the lowest numbered VLAN. The least significant bit of the first octet is invalid. Thus, each protected VLAN of an RRPP domain corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the corresponding VLAN is a protected VLAN of the RRPP domain. By contraries, the VLAN is not a protected VLAN if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainProtectVlanListHigh at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'vlan'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.
OCT h3cRrppDomainProtectVlanListHigh	1.3.6.1.4.1.43.45.1.10.2.45.2.1.1.9	OCTET STRING	read-create	Each octet contained in this value specifies an eight-VLAN group, with the first octet specifying VLANs 2048 through 2055, the second octet specifying VLANs 2056 through 2063, and so on. Within each octet, the most significant bit represents the highest numbered VLAN, and the least significant bit represents the lowest numbered VLAN. The most significant bit of the last octet is invalid. Thus, each protected VLAN of an RRPP domain corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the corresponding VLAN is a protected VLAN of the RRPP domain. By contraries, the VLAN is not a protected VLAN if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainProtectVlanListLow at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'vlan'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.

INT h3cRrppRingNodeMode	1.3.6.1.4.1.43.45.1.10.2.45.2.2.1.5	INTEGER	read-create	There are four RRPP node modes for the switch on a RRPP ring, such as master, transit, edge and assistant-edge. Each RRPP ring has a single designated master-node. All other nodes except edge-node and assistant-edge-node on that ring are referred to as transit-nodes. The node mode of edge and assistant-edge should be configured only on sub-ring. When there is a common link between a sub-ring and its major-ring, the node mode of the sub-ring must be edge or assistant-edge, and they must be configured in pairs. If node mode is designated as edge or assistant-edge, several points should be noticed: Major-ring must be created before a sub-ring is created; Major-ring can't be deleted unless all its sub-rings are deleted; The node mode of the switch on major-ring must be transit; Major-ring and sub-ring must have only a common port. This value can't be modified after created.
