Cisco Bug: CSCvt19116 - Non-MPLS device does not perform 5-tuple hashing for MPLS packets passing through.
May 28, 2020
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: Device does not perform 5-tuple hashing for MPLS packets passing through. Even if switch does not perform label switching and treats packets as simple L2 packets it still does not check inner headers. As result switch does not perform optimal load-balancing over port-channel. Here only src-dst mac of outer L2 header are used only. Conditions: - Switch is acting as simple L2 device - VPC is enabled - Command 'ip load-sharing address source-destination port source-destination inner all' is activated.
