Description: Manages BATM Advanced Communication IP VLAN configuration for routing between VLANs using switch virtual interfaces.

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-SWITCH-IPVLAN-MIB?

This proprietary BATM Advanced Communication MIB manages "IP VLAN" configuration on BATM Layer-3 switches, i.e. the assignment of IP subnets to VLANs so that inter-VLAN routing can occur via switch virtual interfaces. Its data is configuration-oriented, describing which VLAN carries which IP subnet/interface rather than exposing traffic counters or hardware environmental readings. It is used to monitor the software-configuration status of the L3-switching feature — confirming that a VLAN has a correctly assigned IP interface and catching cases where an IP-VLAN binding is missing, duplicated, or in a non-operational row state, which would explain inter-VLAN routing failures. It builds on the same VLAN and IP-addressing concepts standardized in the IETF's Q-BRIDGE-MIB and IP-MIB, tailoring them to BATM's L3-switch implementation. It is deployed on BATM/Telco Systems L3 switches used at network edges and aggregation points where VLAN-based subnet segmentation with local routing is required. Engineers can download the PRVT-SWITCH-IPVLAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PRVT-SWITCH-IPVLAN-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

Since sample_objects is empty for this module, no real table/object names are available to anchor a concrete polling walkthrough; generally, an admin would expect to poll a VLAN-to-IP-subnet mapping table to verify each VLAN has the intended subnet/interface assigned and that the row is active, which would explain a VLAN that cannot route traffic if the mapping is missing or disabled.

OIDs

OID symbolic	OID numeric	Type	Access	Description
prvtSwitchIpVLANMib	1.3.6.1.4.1.738.1.6.2			The IpVLAN MIB module that controls the assignment of IP subnets to VLANs in L3 switches.
ipInterface	1.3.6.1.4.1.738.1.6.2.1
ipInterfaceTable	1.3.6.1.4.1.738.1.6.2.1.1		not-accessible	This table controls the creation of IP interfaces (subnets).
ipInterfaceEntry	1.3.6.1.4.1.738.1.6.2.1.1.1		not-accessible
INT ipInterfaceName	1.3.6.1.4.1.738.1.6.2.1.1.1.1	INTEGER	read-only	This object identifies the name of the IP interface, serves as an index to this table name, and can only be changed during row creation. The name is the integer part of the interface name; sw1 will be 1, sw5 will be 5 etc..
INT ipInterfaceIndex	1.3.6.1.4.1.738.1.6.2.1.1.1.2	INTEGER	read-only	This object identifies the index of the IP interface. This is the same index as ipAdEntIfIndex from MIB-II (ipAddrTable).
INT ipInterfaceType	1.3.6.1.4.1.738.1.6.2.1.1.1.3	INTEGER	read-create	This indicates a status of the IP interface. The value of this object is determined by the IP address. If the IP address field is empty (0.0.0.0) then this interface becomes a pseudo interface.
IP ipInterfaceIpAddress	1.3.6.1.4.1.738.1.6.2.1.1.1.4	IpAddress	read-create	This object has the value of the switch IP address in this subnet. A value of 0.0.0.0 will make this interface a pseudo interface.
IP ipInterfaceSubnetMask	1.3.6.1.4.1.738.1.6.2.1.1.1.5	IpAddress	read-create	This object together with ipInterfaceIpAddress forms the IP subnet, assigned to this IP interface. In case that ipInterfaceIpAddress has the value of 0.0.0.0, this object will be ignored.
ROW ipInterfaceRowStatus	1.3.6.1.4.1.738.1.6.2.1.1.1.6	RowStatus	read-create	This object indicates that the row status, and enables the creation & deletion of rows in this table. See SNMPv2-TC for more information.

IP ipLoInterfaceIpAddress	1.3.6.1.4.1.738.1.6.2.1.2.1.4	IpAddress	read-create	This object has the value of the switch IP address in this subnet. A value of 0.0.0.0 will make this interface a pseudo interface.
IP ipLoInterfaceSubnetMask	1.3.6.1.4.1.738.1.6.2.1.2.1.5	IpAddress	read-create	This object together with ipInterfaceIpAddress forms the IP subnet, assigned to this IP interface. In case that ipInterfaceIpAddress has the value of 0.0.0.0, this object will be ignored.

ipPortMappingTable	1.3.6.1.4.1.738.1.6.2.2.2		not-accessible	This table serves to map physical ports to SW interfaces in their 1:1 relationship. This means that we can map only one SW interface on a
ipPortMappingEntry	1.3.6.1.4.1.738.1.6.2.2.2.1		not-accessible
