natSessionPrivateSrcPort
Module: NAT-MIB
OID (symbolic): NAT-MIB::natSessionPrivateSrcPort
OID (numeric): 1.3.6.1.2.1.123.1.9.1.12
Node type: OBJECT-TYPE
Type: InetPortNumber
Access: read-only
Description: For a protocol value of TCP or UDP, this object represents the source port in the first packet of a session while in a private realm. On the other hand, when the protocol is ICMP, a NAT session is created only for query/response-type ICMP messages such as ICMP echo, Timestamp, and Information request messages, and this object represents the private-realm specific identifier in the ICMP message, as defined in RFC 792 for ICMPv4 and in RFC 4443 for ICMPv6.
The value of this object must be zero when the natSessionPrivateSrcEPBindId object has zero value and value of natSessionPrivateSrcEPBindMode is
addressPortBind(2). In such a case, the NAT session lookup will match any port number to this field.
The value of this object must be zero when the object is not a representative field (SrcPort, DstPort, or ICMP identifier) of the session tuple in either the public realm or the private realm. Deprecated in favor of NATV2-MIB.
What is natSessionPrivateSrcPort?
For TCP/UDP, the private-side source port of the session's first packet; for ICMP, the private-side identifier from an echo/timestamp/info-request message. Can read zero as a wildcard in certain unbound-session cases. Deprecated in favor of NATV2-MIB.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.12 snmpwalk -v2c -c public <target> NAT-MIB::natSessionPrivateSrcPort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.12.1 snmpget -v2c -c public <target> NAT-MIB::natSessionPrivateSrcPort.1
