srcPort
Module: TIARA-DOS-MIB
OID (symbolic): TIARA-DOS-MIB::srcPort
OID (numeric): 1.3.6.1.4.1.3174.2.50.3.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Source Port
What is srcPort?
Reports the source TCP port used by a connection the device has recorded as incomplete. Admins examine it alongside srcIpAddress to characterize the attacking client's connection pattern during a SYN-flood. A cluster of entries all sharing similar high-numbered ephemeral srcPort values from the same address suggests scripted flood traffic rather than legitimate clients.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3174.2.50.3.1.4 snmpwalk -v2c -c public <target> TIARA-DOS-MIB::srcPort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3174.2.50.3.1.4.1 snmpget -v2c -c public <target> TIARA-DOS-MIB::srcPort.1
