Management and Operations · Troubleshooting network security
You are troubleshooting a MACsec link between two Cisco Nexus 9000 switches. The interface status shows 'down' and the MACsec Key Agreement (MKA) session is not established. You observe the following log message:
%MKA-3-INVALID_ICV: Received packet with invalid ICVWhich configuration mismatch is causing this issue?
Show answer & explanation
Correct answer: A
The Integrity Check Value (ICV) is derived from the Connectivity Association Key (CAK), which comes from the configured Pre-Shared Key (PSK). If the PSKs do not match, the derived ICV will verify incorrectly on the receiver, leading to dropped packets and an invalid ICV error log.
