What is pfCntShort?
Counts packets that were too short to even contain a valid protocol header and were therefore dropped. A nonzero and growing value usually points to malformed, truncated, or malicious traffic reaching the firewall.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.4 snmpwalk -v2c -c public <target> OPENBSD-PF-MIB::pfCntShort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.4.1 snmpget -v2c -c public <target> OPENBSD-PF-MIB::pfCntShort.1
