Single ingress and single egress of 400Gbps link speeds between DUT and IXIA.
DUT is DNX based multi-line card chassis with mix of 100 and 400Gbps interfaces.
Static MACSEC + MKA configured on 400Gbps ingress and egress.
IXIA - acting as traffic originator and receiver.
The static MACSEC and MKA shows up on the IXIA before the test. DUT also sees the connectivity UP. However, on starting the test, the MKA connectivity starts flapping, resulting in loss of traffic.
The issue is often seen with 400Gbps interfaces.
Results you see
The MKA connectivity between the DUT and IXIA starts flapping especially when the traffic is started. Restarting the protocol on IXIA or starting the ping sometimes fixes the issue.
Results you expected to see
The MACSEC+MKA connectivity stays UP during the test.
