To resolve the problem:
1. Verify that Layer 2 is operating correctly, as described in "Layer 2 forwarding failure."
2. Verify that Layer 3 is ope
rating correctly, as described in "Layer 3 forwarding failure."
3. Execute the debug rx
tx softcar show 1 command in probe view to check for software-related
packet loss.
