Um...

ericb@marvin:~> grep snmp /etc/services 
snmp            161/udp                         # Simple Net Mgmt Proto
snmp-trap       162/udp         snmptrap        # Traps for SNMP
ericb@marvin:~> grep 167 /etc/services
zsh: 5095 exit 1     grep 167 /etc/services

Yes, you can configure your SNMP agents to use whatever numeric port
you want, but SNMP is virtually always 161/udp.
