dvbNiuNaptAddr
Module: DVB-CABLE-NIU-MIB
OID (symbolic): DVB-CABLE-NIU-MIB::dvbNiuNaptAddr
OID (numeric): 1.3.6.1.3.110.1.1.7.2
Node type: OBJECT-TYPE
Type: InetAddress
Access: read-write
Description: The external IP address to be used for NAPT. The filter table is used to identify internal addresses that require NAPT before entering the external domain (upstream). In the downstream direction NAPT (inverse of the NAPT applied in the upstream) is applied before applying the IP filter table. NAPT assignment algorithims are vendor dependant. The value of all 0's specifies that NAPT is not available and the packet requiring it should be discarded. A value with all bits set to 1 specifies that NAPT will use the IP address assigned to the HFC interface.
NAPT is not applicable to multicast packets.
At initial startup this object has the default value of all 0's
What is dvbNiuNaptAddr?
The external IP address the NIU uses to perform NAPT on outbound subscriber traffic flagged by the IP filter table, applying the inverse translation to matching inbound traffic; all-zeros (the default) disables NAPT and drops traffic that needs it, while all-ones reuses the address assigned to the HFC interface. NAPT is not applied to multicast traffic.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.110.1.1.7.2 snmpwalk -v2c -c public <target> DVB-CABLE-NIU-MIB::dvbNiuNaptAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.110.1.1.7.2.1 snmpget -v2c -c public <target> DVB-CABLE-NIU-MIB::dvbNiuNaptAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.3.110.1.1.7.2.1 s <value>
