Description: Handles BATM Advanced Communication super VLAN (VLAN aggregation) setup, enabling IP address sharing across subscriber VLANs.

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 PRVT-SUPER-VLAN-MIB?

PRVT-SUPER-VLAN-MIB is a vendor-specific enterprise MIB from BATM Advanced Communication for configuring "super VLAN" (VLAN aggregation) functionality, which lets multiple subscriber VLANs share a single IP subnet on its Carrier Ethernet switches. It exposes per-interface super-VLAN configuration together with associated customer VLAN (CVlan) mapping tables and ring-port association tables. Monitoring value here is chiefly configuration/operational-status oriented: row-status fields reveal whether a super-VLAN or a customer VLAN mapping is active, inactive, or improperly provisioned, which helps diagnose broken subscriber connectivity. It sits in the same BATM PRVT enterprise tree as PRVT-ALARM-MIB and related modules and builds conceptually on standard 802.1Q VLAN tagging. It is typically deployed on BATM Carrier Ethernet access switches serving multiple subscriber VLANs over a shared IP uplink, such as in metro Ethernet access networks. Engineers can download the PRVT-SUPER-VLAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PRVT-SUPER-VLAN-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

prvtSuperVlanIfTable/prvtSuperVlanIfEntry rows keyed by prvtSuperVlanIfIndex define a super-VLAN's prvtSuperVlanIfTargetPort and prvtSuperVlanIfRowStatus, while prvtSuperVlanIfCVlanTable/prvtSuperVlanIfCVlanEntry map individual customer prvtSuperVlanIfCVlanId values, with a prvtSuperVlanIfCVlanMask, into that super-VLAN. An admin troubleshooting a subscriber who cannot reach the network would check prvtSuperVlanIfCVlanRowStatus for that customer's VLAN mapping to confirm it is active, and inspect prvtSuperVlanIfRingPortTable entries if the switch sits in a ring topology.

What Can Be Monitored

super-VLAN configuration/row status
customer VLAN (CVlan) ID mapping
CVlan row status
target port assignment
ring port association

OIDs

OID symbolic	OID numeric	Type	Access	Description
prvtSuperVlanMIB	1.3.6.1.4.1.738.1.5.136			Private MIB supporting Super VLANs
prvtSuperVlanMIBObjects	1.3.6.1.4.1.738.1.5.136.1
prvtSuperVlanIfTable	1.3.6.1.4.1.738.1.5.136.1.1		not-accessible	A list of Super-VLAN source ports. A source port must always be associated with either a single target port (specified by a non-zero value for prvtSuperVlanIfTargetPort) or must be associated with a pair of ring ports (specified by creating an entry in prvtSuperVlanIfRingPortTable). Thus when creating a new entry in prvtSuperVlanIfTable, either the object prvtSuperVlanIfTargetPort must be simultaneously set to a valid non-zero ifIndex value or an entry in prvtSuperVlanIfRingPortTable must be simultaneously created to specify the associated ring ports.
prvtSuperVlanIfEntry	1.3.6.1.4.1.738.1.5.136.1.1.1		not-accessible	An entry in prvtSuperVlanIfTable.
NUM prvtSuperVlanIfIndex	1.3.6.1.4.1.738.1.5.136.1.1.1.1	InterfaceIndex	not-accessible	The ifIndex of a Super-VLAN source port.
NUM prvtSuperVlanIfTargetPort	1.3.6.1.4.1.738.1.5.136.1.1.1.2	InterfaceIndexOrZero	read-create	The IfIndex of a target port associated with this Super-VLAN source port. A value of zero indicates that the source port is not associated with a single target port but is associated with a pair of ring ports specified in prvtSuperVlanIfRingPortTable. Changing this object from a zero value to a non-zero value that is a valid ifIndex (i.e. changing from a ring-port to a single target port), will result in the associated entry in prvtSuperVlanIfRingPortTable being automatically deleted.
ROW prvtSuperVlanIfRowStatus	1.3.6.1.4.1.738.1.5.136.1.1.1.3	RowStatus	read-create	The RowStatus for prvtSuperVlanIfTable.
prvtSuperVlanIfCVlanTable	1.3.6.1.4.1.738.1.5.136.1.2		not-accessible	A list of customer VLANs belonging to a Super-VLAN source port.
prvtSuperVlanIfCVlanEntry	1.3.6.1.4.1.738.1.5.136.1.2.1		not-accessible	An entry in prvtSuperVlanIfCVlanTable.
I32 prvtSuperVlanIfCVlanId	1.3.6.1.4.1.738.1.5.136.1.2.1.1	Integer32	not-accessible	The VLAN identifier of a customer VLAN belonging to a Super-VLAN source port.
OCT prvtSuperVlanIfCVlanMask	1.3.6.1.4.1.738.1.5.136.1.2.1.2	OCTET STRING	read-create	The mask to apply to the VLAN identifier (prvtSuperVlanIfCVlanId). A value of all zeros represents that no mask is applied
ROW prvtSuperVlanIfCVlanRowStatus	1.3.6.1.4.1.738.1.5.136.1.2.1.3	RowStatus	read-create	The RowStatus for prvtSuperVlanIfCVlanTable.
prvtSuperVlanIfRingPortTable	1.3.6.1.4.1.738.1.5.136.1.3		not-accessible	This table specifies a pair of ring ports to associate with a Super-VLAN source port. Only a single pair of ring ports may be associated per source port. A source port must always be associated with either a single target port (specified by a non-zero value for prvtSuperVlanIfTargetPort) or must be associated with a pair of ring ports (specified by creating an entry in prvtSuperVlanIfRingPortTable). When an entry is successfully created in prvtSuperVlanIfRingPortTable for a particular source port, that source port's prvtSuperVlanIfTargetPort object is automatically set to a zero value indicating that the source port is associated with a pair of ring ports instead of a single target port (i.e. when creating an entry in prvtSuperVlanIfRingPortTable, it is not neccessary to also clear prvtSuperVlanIfTargetPort).
prvtSuperVlanIfRingPortEntry	1.3.6.1.4.1.738.1.5.136.1.3.1		not-accessible	An entry in prvtSuperVlanIfRingPortTable.
NUM prvtSuperVlanIfRingPort1	1.3.6.1.4.1.738.1.5.136.1.3.1.1	InterfaceIndex	not-accessible	The ifIndex of the first ring port target associated with this Super-VLAN source port.
NUM prvtSuperVlanIfRingPort2	1.3.6.1.4.1.738.1.5.136.1.3.1.2	InterfaceIndex	not-accessible	The ifIndex of the second ring port target associated with this Super-VLAN source port.
I32 prvtSuperVlanIfRingPortVlanId	1.3.6.1.4.1.738.1.5.136.1.3.1.3	Integer32	read-create	The VLAN to use in Spanning Tree decisions to determine the active Super-VLAN port. The value '0' indicates no VLAN has been selected.
NUM prvtSuperVlanIfRingPortPreferred	1.3.6.1.4.1.738.1.5.136.1.3.1.4	InterfaceIndexOrZero	read-create	The ifIndex of the preferred ring port to use for this ring.
NUM prvtSuperVlanIfRingPortActive	1.3.6.1.4.1.738.1.5.136.1.3.1.5	InterfaceIndexOrZero	read-only	The ifIndex of the currently active ring port for this ring.
ROW prvtSuperVlanIfRingPortRowStatus	1.3.6.1.4.1.738.1.5.136.1.3.1.6	RowStatus	read-create	The RowStatus for prvtSuperVlanIfRingPortTable.
