secyStatsRxNoSAPkts
Module: IEEE8021-SECY-MIB
OID (symbolic): IEEE8021-SECY-MIB::secyStatsRxNoSAPkts
OID (numeric): 1.0.8802.1.1.3.1.2.5.1.9
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of received packets with an unknown SCI or for an unused SA.
What is secyStatsRxNoSAPkts?
This counter tallies received packets with unknown Security Channel Identifiers (SCI) or for unused Security Associations on a secure MAC interface, indicating packets that failed authentication. An operator monitors this to detect unauthorized transmitters, configuration mismatches, or Man-in-the-Middle attacks on MACsec-protected links. Rising counts trigger investigation of link security and SA configuration consistency.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.0.8802.1.1.3.1.2.5.1.9 snmpwalk -v2c -c public <target> IEEE8021-SECY-MIB::secyStatsRxNoSAPkts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.0.8802.1.1.3.1.2.5.1.9.1 snmpget -v2c -c public <target> IEEE8021-SECY-MIB::secyStatsRxNoSAPkts.1
