secyRxSALowestXPN

Module: IEEE8021-SECY-MIB

OID (symbolic): IEEE8021-SECY-MIB::secyRxSALowestXPN

OID (numeric): 1.0.8802.1.1.3.1.1.5.1.9

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The lowest acceptable packet number. A received frame with a lower PN is discarded if secyIfReplayProtectEnable is enabled.

What is secyRxSALowestXPN?

The lowest packet number this receive SA will still accept; an incoming frame with a lower PN is discarded when secyIfReplayProtectEnable is enabled, which is how MACsec blocks replayed frames.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.0.8802.1.1.3.1.1.5.1.9
snmpwalk -v2c -c public <target> IEEE8021-SECY-MIB::secyRxSALowestXPN

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.0.8802.1.1.3.1.1.5.1.9.1
snmpget -v2c -c public <target> IEEE8021-SECY-MIB::secyRxSALowestXPN.1
