A mismatched flow error occurs if MAC-based hashing is configured for a Layer 2 interface and the user is trying to display a Layer 3 flow. The output will display three entries: Example • Egress port for unfragmented packets. • In the event of fragmented packets, egress port of the first fragment. • In the event of fragmented packets, egress port of the subsequent fragments. Note: In the show port channel flow command output, the egress port for an unknown unicast, multicast or broadcast traffic is not displayed. show port-channel-flow outgoing-port-channel number incoming-interface interface source-mac address destination-mac address • Load-balance is configured for MAC • Load-balance is configured for IP 4-tuple/2-tuple for the C-Series and S-Series • A non-IP payload is going out of Layer 2 LAG interface that is a member of VLAN with an IP address.

Time Domain Reflectometer (TDR) c e s TDR is useful for troubleshooting an interface that is not establishing a link; either it is flapping or not coming up at all. TDR detects open or short conditions of copper cables on 100/1000 Base-T modules. 670 | Interfaces
