natTcpDefIdleTimeout
Module: NAT-MIB
OID (symbolic): NAT-MIB::natTcpDefIdleTimeout
OID (numeric): 1.3.6.1.2.1.123.1.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The default time interval that a NAT session for an established TCP connection is allowed to remain valid without any activity on the TCP connection.
If the agent is capable of storing non-volatile configuration, then the value of this object must be restored after a reinitialization of the management system.
Deprecated in favor of NATV2-MIB.
What is natTcpDefIdleTimeout?
Default idle timeout, in seconds, for an already-established TCP connection passing through NAT, defaulting to 86400 seconds (24 hours). This is why long-lived idle TCP sessions (e.g. an SSH session left open overnight) can survive through a NAT device without being retranslated; deprecated in favor of NATV2-MIB.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.1.5 snmpwalk -v2c -c public <target> NAT-MIB::natTcpDefIdleTimeout
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.1.5.1 snmpget -v2c -c public <target> NAT-MIB::natTcpDefIdleTimeout.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.123.1.1.5.1 i <value>
