adUnitTraceRtPortNum
Module: ADTRAN-ADUNIT-MIB
OID (symbolic): ADTRAN-ADUNIT-MIB::adUnitTraceRtPortNum
OID (numeric): 1.3.6.1.4.1.664.5.30.3.6.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Set the base UDP port number used in probes. Traceroute operation is based on the fact that nothing is listening on UDP ports base to base + nhops - 1 at the destination host (so an ICMP PORT_UNREACHABLE message will be returned to terminate the route tracing). If something is listening on a port in the default range, this option can be used to pick an unused port range.
What is adUnitTraceRtPortNum?
This read-write field (1-65535) specifies the base UDP port number for traceroute probes, allowing you to work around devices that block the default probe port range. A network engineer changes this when firewalls or security policies block standard UDP port ranges used for traceroute. Setting this to 33434 (the traditional starting port) or 50000 helps bypass filters that only allow specific port ranges.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.664.5.30.3.6.8 snmpwalk -v2c -c public <target> ADTRAN-ADUNIT-MIB::adUnitTraceRtPortNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.664.5.30.3.6.8.1 snmpget -v2c -c public <target> ADTRAN-ADUNIT-MIB::adUnitTraceRtPortNum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.664.5.30.3.6.8.1 i <value>
