Description: Manages ARP table configuration, static entry provisioning, and proxy-ARP settings on Paradyne Networks xDSL access devices.

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-ARP-MIB?

PDN-ARP-MIB is a Paradyne Networks enterprise MIB for configuring and displaying ARP (Address Resolution Protocol) table behavior on Paradyne xDSL access devices. It exposes objects for global ARP timeout tuning (complete, incomplete, and default-route entry timeouts), a periodic-request table for proactively re-resolving specific IP addresses, and a configuration table for per-entry ARP settings. Its monitoring/configuration use is mostly around IP-layer connectivity health -- confirming ARP entries refresh on schedule, checking how soon a periodic ARP request will next fire for a monitored address, and validating static/dynamic ARP configuration rather than exposing hardware sensors. It builds on the standard IP-to-media (ARP) table concept from the IP-MIB, adding Paradyne-specific timeout and periodic-request behavior on top. It is deployed on Paradyne xDSL access/DSLAM equipment where administrators need finer control over ARP aging and proactive address resolution than the standard IP-MIB provides. Network engineers evaluating or troubleshooting this functionality can download the PDN-ARP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PDN-ARP-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 operator reads pdnNetToMediaParamsAprTable/Entry (indexed by pdnNetToMediaParamsAprIpAddr) to see pdnNetToMediaParamsAprTimeToNext and confirm a critical peer's address is being proactively re-resolved on the configured pdnNetToMediaParamsAprReqPeriod. Comparing pdnNetToMediaParamsCompEntryTimeout and pdnNetToMediaParamsIncompEntryTimeout against expected values catches misconfigured ARP aging that could cause stale entries or excessive ARP traffic. pdnNetToMediaConfigTable/Entry (by pdnNetToMediaConfigIpAddr) lets an admin confirm a specific static ARP entry's row status is active.

What Can Be Monitored

ARP entry timeout settings
periodic ARP request schedule

OID symbolic	OID numeric	Type	Access	Description
pdn_arp	1.3.6.1.4.1.1795.2.24.2.27			This MIB contains objects that are used to configure ARP entries and display ARP information. ================================================================= == == == Copyright (C) 2005 Paradyne Networks, Inc. == == == =================================================================
pdnNetToMediaGenericMIBObjects	1.3.6.1.4.1.1795.2.24.2.27.1
pdnNetToMediaParams	1.3.6.1.4.1.1795.2.24.2.27.1.1
I32 pdnNetToMediaParamsCompEntryTimeout	1.3.6.1.4.1.1795.2.24.2.27.1.1.1	Integer32	read-write	Complete Entry Timeout is the length of time that a complete entry remains in the ARP table before removal. A complete entry is one for which there is a MAC address -- i.e. a node has responded to the ARP request. If an entry gets this old without being referenced, it will be removed from the table. The range for this parameter is 1 to 200000 minutes.
I32 pdnNetToMediaParamsIncompEntryTimeout	1.3.6.1.4.1.1795.2.24.2.27.1.1.2	Integer32	read-write	Incomplete Entry Timeout is the length of time that an incomplete entry remains in the ARP table before removal. An incomplete entry is one for which there is no MAC address -- i.e. an ARP request has been made, but no response has been received. This is also the amount of time that a packet will remain in the system while waiting for address resolution. The range for this parameter is 1 to 255 minutes.
I32 pdnNetToMediaParamsDefRouteEntryTimeout	1.3.6.1.4.1.1795.2.24.2.27.1.1.3	Integer32	read-write	Default Route Entry Timeout is the length of time a default route entry will remain in the ARP table. If default route gets this old without being referenced, an ARP request will be sent to the next hop router. If no response is received, it will be removed from the ARP table and the card will switch to the next reachable default route with the highest preference. The range for this parameter is 1 to 20 minutes.
