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
