natSessionPublicDstPort

Module: NAT-MIB

OID (symbolic): NAT-MIB::natSessionPublicDstPort

OID (numeric): 1.3.6.1.2.1.123.1.9.1.19

Node type: OBJECT-TYPE

Type: InetPortNumber

Access: read-only

Description: When the protocol value is TCP or UDP, this object represents the destination port in the first packet of session while in the public realm. On the other hand, when

the protocol is ICMP, this object is not relevant for translation and should be zero.

The value of this object must be zero when the natSessionPrivateDstEPBindId object has a zero value and natSessionPrivateDstEPBindMode is addressPortBind(2). In such a scenario, 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 natSessionPublicDstPort?

For TCP/UDP, the public-side destination port of the session; not relevant (and zero) for ICMP. Deprecated in favor of NATV2-MIB.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.19
snmpwalk -v2c -c public <target> NAT-MIB::natSessionPublicDstPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.9.1.19.1
snmpget -v2c -c public <target> NAT-MIB::natSessionPublicDstPort.1
