.1AE Management Info
• LMI (Layer Management Interface)
– Data Structure
– Accessed by .1AE, .1af, SNMP/MIB, EAP
– Containing .1AE and .1af configuration,
protocol states, and counter/diagnosis
information.
– .1AE uses LMI to control the MACsec packet
processing directly or through APIs.
– Change the data in LMI may cause actions in
SecY or KaY
.1AE Management Info
• MACsec Mgmt Information
– Multiple Control Flags to control MACsec status. (global objects)
(To have the transition of deployment smoothly.)
– Status of MACsec (macSecStatus)
– rxSecYSCCapability : number peer receiving SCs per
SecY can have.
• SecY Mgmt Information
– Table indexed by InterfaceIndex (IF-MIB).
– ValidateRxFrames : flag for validation process in
receiving. (10.5.3)
– ProtectTxFrames : flag for protection process in
transmitting.
– Current Cipher Suite. (10.5.4) (Row Pointer)
– adminPointToPointMAC, operPointToPointMAC (6.5)
.1AE Management Info
– RxReplayChk : flag for rx replay check.
(10.6.2)
– Tx SC : transmit SC informaiton.
– Rx SCs : receive SCs informaiton. (will be in
another table.)
– lastUnknownSC : an SCI information to record
last rx unknown SC (10.6.1) with time stamp.
.1AE Management Info
• Tx SC Mgmt Information
– scState : state of this transmit SC ? (rolled from
saState informaiton.)
– SCI : the SCI for the SC used by SecY for transmit.
(10.5)
– txEncodingSA : current SA number. (Integer) (10.5.1)
– txEncipheringSA : previous SA number. (Integer)
(10.5.4)
• Tx SA : (table with 4 entries)
–
–
–
–
Table indexed by InterfaceIndex and AN.
saState : state of this transmit SA.
saCmd : command executing in the SA.
txSAK : key for transmitting. (7.1, 10.5.1) (not in the
MIB.)
– txNextPN : next packet number (PN). (10.5.2)
.1AE Management Info
• Rx SCs Mgmt Information
– Table indexed by InterfaceIndex and SCI.
– scState : state of this receive SC ? (rolled
from saState).
– SCI : the SCI for the SC used by SecY for
receive. (10.5)
– rxCurrentSA : current using SA number in the
SC. (Integer) (10.6.1)
– lastUnknownSA : last un-resolved AN with
timestamp. (10.6.1)
.1AE Management Info
• Rx SA Mgmt Information
–
–
–
–
Table indexed by InterfaceIndex and SCI and AN.
saState : state of this receive SA.
saCmd : command excecuting in the SA.
rxSAK : key for receiving. (7.1, 10.6.1) (not in the
MIB.)
– rxLastPN : last received packet number (PN). (10.6.2)
– rxLastValidatedPN : last received validated PN.
(10.6.2)
.1AE Management Info
• Cipher Suites :
– Name : name of this cipher suite, could be MIB table
index.
– Description : information about the Cipher Suite.
– Confidentiality : flag indicate the cipher suite with
confidentiality ability.
– SecureDataLengthChange : a flag to indicate the
length of ciphered text is different from the length of
plain text.
– ICV length : the length of generated ICV.
.1AE Management Info
• SA Rx Counters :
– Table indexed by InterfaceIndex and SCI and AN
– InCntReinitTime : A timestamp for the counters’
discontinuity in this SA.
– OutCntStopTime : A timestamp for the counters’
discontinuity in this SA, stop time.
– InXcastPktsNotReceived (the name will be modified
to represent the real meaning.)
