natTcpDefNegTimeout
Module: NAT-MIB
OID (symbolic): NAT-MIB::natTcpDefNegTimeout
OID (numeric): 1.3.6.1.2.1.123.1.1.6
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The default time interval that a NAT session for a TCP connection that is not in the established state 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 natTcpDefNegTimeout?
Default idle timeout, in seconds, for a TCP connection that hasn't yet reached the established state (e.g. mid-handshake), defaulting to 60 seconds. A much shorter value than natTcpDefIdleTimeout since half-open connections are more likely to be abandoned or malicious; deprecated in favor of NATV2-MIB.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.1.6 snmpwalk -v2c -c public <target> NAT-MIB::natTcpDefNegTimeout
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.1.6.1 snmpget -v2c -c public <target> NAT-MIB::natTcpDefNegTimeout.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.123.1.1.6.1 i <value>
