Description: Extends IEEE 802.1Q VLAN management with Paradyne-specific port tagging, ingress-filtering, and PVID configuration objects.

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 PDN-DOT1QEXT-MIB?

This is a Paradyne Corporation enterprise MIB that extends the standard IEEE 802.1Q VLAN MIB (RFC 2674) with vendor-specific per-VLAN and per-port configuration objects not covered by the base standard. It exposes VLAN-level configuration data such as secure mode status, proxy ARP status, uplink designation, default next-hop router, and outer (Q-in-Q) tag/priority/ethertype settings, along with a port-level PIWG table. It is used to monitor the configuration/software status of VLAN security and tagging features, confirming whether secure mode or proxy ARP is enabled per VLAN, and whether Q-in-Q outer tagging parameters are set correctly, which helps diagnose VLAN isolation or double-tagging issues. It has an explicit, stated dependency on the IETF Q-BRIDGE-MIB (RFC 2674), whose VLAN objects it augments with these additional configuration parameters. It is typically deployed on Paradyne access devices providing VLAN-aware Ethernet access, including Q-in-Q service-provider VLAN tunneling scenarios. Engineers can download the PDN-DOT1QEXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PDN-DOT1QEXT-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 pdnDot1qVlanStaticExtTable (via pdnDot1qVlanStaticExtEntry) to check pdnDot1qVlanStaticSecureModeStatus and pdnDot1qVlanStaticProxyArpStatus for a given VLAN, confirming security features are enabled as expected. Checking pdnDot1qVlanStaticOuterTag, pdnDot1qVlanStaticOuterDefaultPriority, and pdnDot1qVlanStaticOuterEthertype would reveal whether Q-in-Q outer-tag parameters match what the upstream provider network expects, explaining a double-tagging mismatch. The pdnDot1qVlanStaticUplink and pdnDot1qVlanStaticDefaultNHR objects would confirm which port is designated uplink and which router handles default traffic for the VLAN, giving operators fine control-plane visibility beyond the base 802.1Q MIB.

What Can Be Monitored

VLAN secure mode status
proxy ARP status per VLAN
uplink port designation
Q-in-Q outer tag/priority/ethertype
default next-hop router configuration

OIDs

OID symbolic	OID numeric	Type	Access	Description
pdnDot1qExt	1.3.6.1.4.1.1795.2.24.2.39.1			The Paradyne enterprise DOT1q extension MIB. This MIB provides additional DOT1q configuration objects not provided by rfc2674.
pdnDot1qExtObjects	1.3.6.1.4.1.1795.2.24.2.39.1.1
pdnDot1qVlanStaticExtTable	1.3.6.1.4.1.1795.2.24.2.39.1.1.1		not-accessible	The Paradyne dot1qVlanStatic extension table. This table is used for configuring extensions to static vlans.
pdnDot1qVlanStaticExtEntry	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1		not-accessible	An entry in the Paradyne dot1q extension to Static Vlan Table
INT pdnDot1qVlanStaticSecureModeStatus	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.1	INTEGER	read-write	This is objects configure secure mode status for the selected VLAN. The secure VLAN mode implies that the users on this VLAN cannot talk to users on a different VLAN. This setting also validates the configuration of the next three objects in this table. If the pdnDot1qVlanStaticSecureModeStatus is disabled non of the other three objects configurations apply.
INT pdnDot1qVlanStaticProxyArpStatus	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.2	INTEGER	read-write	This objects enables/disabled proxy arp on secure VLAN. If the VLAN is secure, it can optionally have Proxy ARP enabled. This object is not valid unless pdnDot1qVlanStaticSecureModeStatus is set to ENABLED.This object will be disabled(1) by default.
I32 pdnDot1qVlanStaticUplink	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.3	Integer32	read-write	This is used to configure the port number of the port on which all frames belonging to secure VLAN are to be forwarded. This object is not valid unless pdnDot1qVlanStaticSecureModeStatus is set to ENABLED. If pdnDot1qVlanStaticSecureModeStatus is disabled this object will read 0 port.
IP pdnDot1qVlanStaticDefaultNHR	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.4	IpAddress	read-write	This object is used to configure Default Next Hop Router Ip Address that would be used only if the Next Hop Router cannot be learned (i.e from snooping messages). This object is not valid unless pdnDot1qVlanStaticSecureModeStatus is set to ENABLED. If pdnDot1qVlanStaticSecureModeStatus is disabled this object will read 0.0.0.0 address.
I32 pdnDot1qVlanStaticOuterTag	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.5	Integer32	read-write	When VLAN stacking (Q in Q) is desired, this object contains the value of the outer 802.1q VLAN outer tag. A value of zero (0) indicates that VLAN stacking is not enabled.
I32 pdnDot1qVlanStaticOuterDefaultPriority	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.6	Integer32	read-write	When VLAN stacking (Q in Q) is desired, this object contains the default value of the priority bits in the 802.1q VLAN outer tag for unknown unicast, broadcast and multicast packets. For known unicast traffic, the inner VLAN tag priority is copied to the outer tag priority. If pdnDot1qVlanStaticOuterTag (above) is zero (0) this object is ignored.
I32 pdnDot1qVlanStaticOuterEthertype	1.3.6.1.4.1.1795.2.24.2.39.1.1.1.1.7	Integer32	read-write	When VLAN stacking (Q in Q) is desired, this object contains the value of the ethertype in the 802.1q VLAN outer tag. If pdnDot1qVlanStaticOuterTag (above) is zero (0) this object is ignored.
pdnDot1BasePortPIWGTable	1.3.6.1.4.1.1795.2.24.2.39.1.1.2		not-accessible	This table allows mapping of Bridge Ports and Priorities. In General, every bridge port has an associated physical port port (identified by its ifIndex). This relationship is defined in the Dot1dBasePortTable (RFC1493). In addition, each bridge port is associated with one priority (PIWG) from a range of valid priorities. This table defines this relationship. The range of priorities can vary from product to product.
pdnDot1BasePortPIWGEntry	1.3.6.1.4.1.1795.2.24.2.39.1.1.2.1		not-accessible	The priority (PIWG) defined on a Bridge port.
U32 pdnDot1BasePort	1.3.6.1.4.1.1795.2.24.2.39.1.1.2.1.1	Unsigned32	not-accessible	This object specifies the bridge port associated with this PIWG
U32 pdnDot1BasePortPIWGId	1.3.6.1.4.1.1795.2.24.2.39.1.1.2.1.2	Unsigned32	read-only	This is the integer identifier of the priority (PIWG)
OID pdnDot1BasePortPIWGCircuit	1.3.6.1.4.1.1795.2.24.2.39.1.1.2.1.3	OBJECT IDENTIFIER	read-only	This is the object identifier of the priority (PIWG), The value of this object must be a valid identifier defined under the Paradyne Enterprise Definitions (pdn_Header.mib).
TBL pdnDot1TpFdbClear	1.3.6.1.4.1.1795.2.24.2.39.1.1.3	TblCmd	read-write	This object is used to perform a clear on the Bridge Forwarding Table (dot1dTpFdbTable). A set operation to this object with the value of 'clear (2)' will clear the entire Bridge Forwarding Table. A get operation will always return the value of 'noCmd (1)'.
pdnDot1qExtConformance	1.3.6.1.4.1.1795.2.24.2.39.1.2
pdnDot1qExtGroups	1.3.6.1.4.1.1795.2.24.2.39.1.2.1
