Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is TELDAT-MON-PROTOCOL-NAPT-MIB?

TELDAT-MON-PROTOCOL-NAPT-MIB is a Teldat, S.A. proprietary MIB monitoring NAPT (Network Address Port Translation) session and port-pool usage on Teldat routers. Its NAPT table, keyed by index, records source address/port, translated (new) port, session age, and two delta counters, a connection table records source address/identifier, new identifier, and age, and further objects report reserved/used/free port-address and identifier-address pool sizes and per-interface used/free port counts. As a performance MIB it lets an administrator watch NAPT port-pool exhaustion and active session counts on a Teldat router. It is deployed on Teldat, S.A. routers. Engineers can download the TELDAT-MON-PROTOCOL-NAPT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TELDAT-MON-PROTOCOL-NAPT-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.

Supported Devices

Teldat, S.A. routers

Monitoring Examples

An administrator monitors telProdNpMonProtIPNAPTMemUsedPorts against the reserved pool size to catch NAPT port-pool exhaustion on a Teldat router.

OIDs

OID symbolic	OID numeric	Type	Access	Description
telProdNpMonProtIPNAPTMonit	1.3.6.1.4.1.2007.4.1.2.3.1.11
telProdNpMonProtIPNAPTTable	1.3.6.1.4.1.2007.4.1.2.3.1.11.1		not-accessible	NAPT connections table: Network Address Port Translation.
telProdNpMonProtIPNAPTEntry	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1		not-accessible	Each entry is a NAPT connection in which a change of ports is performed (NAT of ports). It consists of an index that shows the position of the entry in the table, the source address, the source port, the new port to which it has been translated, the time passed since that entry was used for the last time and the delta values.
INT telProdNpMonProtIPNAPTIndex	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.1	INTEGER	read-only	Table index: position of the entry (NAPT connection).
IP telProdNpMonProtIPNAPTSrcAddr	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.2	IpAddress	read-only	Source IP address.
INT telProdNpMonProtIPNAPTSrcPort	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.3	INTEGER	read-only	Source port.
INT telProdNpMonProtIPNAPTNewPort	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.4	INTEGER	read-only	New port: the port assigned after the translation. In the case the index and port number were different, this variable would take the value 0.
INT telProdNpMonProtIPNAPTAge	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.5	INTEGER	read-only	Time to live of the entry before being deleted.
INT telProdNpMonProtIPNAPTDeltFst	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.6	INTEGER	read-only	First parameter related to the deltas. The deltas show the difference in the number of bytes that exist in the packets before and after the port and address translation in FTP connections. FTP connections are not clear thus they require changes inside the packets exchanged during the connection.
INT telProdNpMonProtIPNAPTDeltSnd	1.3.6.1.4.1.2007.4.1.2.3.1.11.1.1.7	INTEGER	read-only	First parameter related to the deltas. The deltas show the difference in the number of bytes that exist in the packets before and after the port and address translation in FTP connections. FTP connections are not clear thus they require changes inside the packets exchanged during the connection.
telProdNpMonProtIPNAPTConnTable	1.3.6.1.4.1.2007.4.1.2.3.1.11.2		not-accessible	Table of the connections that do not use port and therefore they do not appear in the table of connections in which a port translation has occured. In these connections there is a change in the connection identifier. It belongs to NAPT.
telProdNpMonProtIPNAPTConnEntry	1.3.6.1.4.1.2007.4.1.2.3.1.11.2.1		not-accessible	Each entry is one of the connections that do not use ports and therefore do not appear in the connections table with port change. There is a change in the connection identifier. It consists of an index that shows the entry position inside the table, the source address, the source identifier, the new assigned identifier and the time passed since the connection was used for the last time.
INT telProdNpMonProtIPNAPTConnIndex	1.3.6.1.4.1.2007.4.1.2.3.1.11.2.1.1	INTEGER	read-only	Table index: position of the current entry. Each entry keeps information about one of the connections with identifier change. This connections do not use ports thus it is impossible to change them and therefore they don't generate an entry in the table that keeps the connections with port translation.
IP telProdNpMonProtIPNAPTConnSrcAddr	1.3.6.1.4.1.2007.4.1.2.3.1.11.2.1.2	IpAddress	read-only	Source IP address.

INT telProdNpMonProtIPNAPTConnNewIdent	1.3.6.1.4.1.2007.4.1.2.3.1.11.2.1.4	INTEGER	read-only	New assigned identifier.
INT telProdNpMonProtIPNAPTConnAge	1.3.6.1.4.1.2007.4.1.2.3.1.11.2.1.5	INTEGER	read-only	Time to live of the entry before being deleted.
