Description: Manages IP routing configuration, ARP tables, and layer-3 interface parameters on Allied Telesis routers and switches.

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 AT-IP-MIB?

This is a vendor-specific MIB from Allied Telesis for IP routing configuration, ARP table, and layer-3 interface parameters on Allied Telesis routers and switches. It exposes Allied Telesis-specific extensions to IP-layer configuration and status beyond what the standard IP-MIB provides. It supports monitoring the software status of the routing layer — confirming ARP resolution, IP interface configuration, and routing-related parameters are correct and current — which helps diagnose layer-3 connectivity problems. It explicitly extends and works alongside the standard IETF IP-MIB (RFC 4293) rather than replacing it. It is deployed across the Allied Telesis router/layer-3 switch product line for management of IP routing/ARP behavior specific to AT firmware. Engineers can download the AT-IP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AT-IP-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

No sample objects were captured, but an AT-specific IP MIB of this kind would typically expose ARP-table-style entries and IP interface configuration objects (an atIp*Table/Entry pattern) supplementing the standard ipNetToMediaTable. An administrator would cross-check this AT-specific ARP/IP data against the standard IP-MIB when troubleshooting a host that isn't resolving correctly at layer 3.

What Can Be Monitored

ARP table entries
IP interface configuration
layer-3 routing parameters

OIDs

OID symbolic	OID numeric	Type	Access	Description
atIpMib	1.3.6.1.4.1.207.8.4.4.4.602			The IP MIB - for AT specific IP management.
atIpAddressTable	1.3.6.1.4.1.207.8.4.4.4.602.1		not-accessible	A table containing mappings between primary/secondary IP addresses, and the interfaces they are assigned to.
atIpAddressEntry	1.3.6.1.4.1.207.8.4.4.4.602.1.1		not-accessible	An address mapping for a particular interface.
IPt atIpAddressAddrType	1.3.6.1.4.1.207.8.4.4.4.602.1.1.1	InetAddressType	not-accessible	An indication of the IP version of atIpAddressAddr.
IP atIpAddressAddr	1.3.6.1.4.1.207.8.4.4.4.602.1.1.2	InetAddress	not-accessible	The IP address to which this entry's addressing information pertains. The address type of this object is specified in atIpAddressAddrType.
INT atIpAddressPrefixLen	1.3.6.1.4.1.207.8.4.4.4.602.1.1.3	INTEGER	read-create	The prefix length of the IP address represented by this entry.
STR atIpAddressLabel	1.3.6.1.4.1.207.8.4.4.4.602.1.1.4	DisplayString	read-create	A name assigned to the IP address represented by this entry.
NUM atIpAddressIfIndex	1.3.6.1.4.1.207.8.4.4.4.602.1.1.5	InterfaceIndex	read-create	The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.
ADR atIpAddressAssignmentType	1.3.6.1.4.1.207.8.4.4.4.602.1.1.6	AtIpAddressAssignmentType	read-create	The IP address assignment type for this entry (primary or secondary).
ROW atIpAddressRowStatus	1.3.6.1.4.1.207.8.4.4.4.602.1.1.7	RowStatus	read-create	The current status of the IP address entry. The following values may be returned when reading this object: active (1) - The IP address is currently mapped to an interface and is valid. notReady (3) - The IP address is currently partially configured and is not mapped to an interface. The following values may be written to this object: active (1) - An attempt will be made to map the IP address to the configured interface. createAndWait (5) - An attempt will be made to create a new IP address entry. destroy (6) - The IP address setting will be removed from the device. An entry cannot be made active until its atIpAddressPrefixLen, atIpAddressIfIndex and atIpAddressAssignmentType objects have been set to valid values.
