ieee8021XKayMacSecConfidentialityOffset
Module: IEEE8021X-PAE-MIB
OID (symbolic): IEEE8021X-PAE-MIB::ieee8021XKayMacSecConfidentialityOffset
OID (numeric): 1.3.111.2.802.1.1.15.1.6.1.1.17
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The confidentiality protection offset options for the selected cipher suite in the MACsec. If the cipher suite does not have this capability, the configured value of the object will not apply to the cipher suite.
What is ieee8021XKayMacSecConfidentialityOffset?
Sets the confidentiality (encryption) offset in bytes -- 0, 30, or 50 -- used by the selected MACsec cipher suite on this port; some cipher suites don't support offsets other than 0, in which case this setting is simply ignored for that suite. Admins would set 30 or 50 to leave certain header bytes (e.g. for downstream QoS classification) unencrypted while still protecting the payload.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.15.1.6.1.1.17 snmpwalk -v2c -c public <target> IEEE8021X-PAE-MIB::ieee8021XKayMacSecConfidentialityOffset
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.15.1.6.1.1.17.1 snmpget -v2c -c public <target> IEEE8021X-PAE-MIB::ieee8021XKayMacSecConfidentialityOffset.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.111.2.802.1.1.15.1.6.1.1.17.1 i <value>
