natSessionPrivateSrcAddr

Module: NAT-MIB

OID (symbolic): NAT-MIB::natSessionPrivateSrcAddr

OID (numeric): 1.3.6.1.2.1.123.1.9.1.11

Node type: OBJECT-TYPE

Type: InetAddress

Access: read-only

Description: The source IP address of the session endpoint that lies in the private network.

The value of this object must be zero only when the natSessionPrivateSrcEPBindId object has a zero value. When the value of this object is zero, the NAT session lookup will match any IP address to this field.

The type of this address is determined by the value of the natSessionPrivateAddrType object. Deprecated in favor of NATV2-MIB.

What is natSessionPrivateSrcAddr?

The private-network source IP address of this session's endpoint before translation, e.g. the internal workstation's real address; can be zero (a wildcard match) only when there's no fixed source-endpoint binding. Deprecated in favor of NATV2-MIB.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.11
snmpwalk -v2c -c public <target> NAT-MIB::natSessionPrivateSrcAddr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.11.1
snmpget -v2c -c public <target> NAT-MIB::natSessionPrivateSrcAddr.1
