example 1
[0070] Example 1 is a method comprising establishing, by a first network device over a first network link, a Media Access Control Security (MACsec) session with a second network device, the MACsec session including a predefined session timeout threshold, the A session timeout threshold defines the maximum elapsed time between receipt of two sequential MACsec Key Agreement Protocol Data Units (MKPDUs) from the second network device through the MACsec session; monitoring through the MACsec session pairs from The elapsed time between the reception of two sequential MKPDUs of the network device; the elapsed time is compared with a predefined alarm time threshold, which is less than the session timeout threshold and optionally generating a MACsec link alarm based on the comparison.
[0071] In Example 2, the technical solution of Example 1 optionally includes wherein the predefined session timeout threshold is equivalent to the MKA lifetime.
[0072] In example 3, the technical so...
example 11
[0080] Example 11 is a system comprising: hardware processing circuitry; one or more hardware memories storing instructions that, when executed, configure the hardware processing circuitry to perform operations comprising: establishing, by the first network device over the first network link, a Media Access Control Security (MACsec) session with the second network device, the MACsec session including a predefined session timeout threshold defined by the MACsec session The maximum elapsed time between receipt of two sequential MACsec Key Agreement Protocol Data Units (MKPDUs) to the second network device; monitoring the response to two sequential MACsec sessions from the network device through the MACsec session; elapsed time between receipts of MKPDUs; comparing the elapsed time to a predefined alert time threshold, the predefined alert time threshold representing an elapsed time less than the session timeout threshold; and selectively based on the This comparison is used to g...
