Jan 30, 2017
- Cisco Nexus 3000 Series Switches
- Cisco Nexus 3548 Switch
Known Affected Releases
Symptom:Traceroute to a Nexus3000/3500 fails, as the ICMP packet sent out by the switch has same source and destination IP address. E.g., A host with IP address 10.10.10.2/24 sends traceroute (UDP) to 10.10.10.1 (configured in N3K). The ICMP port-unreachable sent out by N3K has source and destination IP address of 10.10.10.1. Conditions:Nexus 3000/3500 running one of the affected releases.
