pfCntTimestamp
Module: OPENBSD-PF-MIB
OID (symbolic): OPENBSD-PF-MIB::pfCntTimestamp
OID (numeric): 1.3.6.1.4.1.30155.1.2.7
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of packets that were dropped due to improper RFC1323 timestamp.
What is pfCntTimestamp?
Counts packets dropped for carrying an invalid TCP timestamp option per RFC1323, which pf's normalization checks flag as suspicious. A growing count typically reflects scrub-rule enforcement against malformed or spoofed TCP traffic.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.7 snmpwalk -v2c -c public <target> OPENBSD-PF-MIB::pfCntTimestamp
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.7.1 snmpget -v2c -c public <target> OPENBSD-PF-MIB::pfCntTimestamp.1
