The above warning messages are logged on a switch when IPFIX is enabled globally and egress IPFIX is enabled on a port.
These messages signify some number of (at least 1) IPFIX reports from the hardware that could not be properly reported, and were as a result incorrectly reported, i.e., with the incorrect ingress or egress interface
Such messages are informational and could be useful if you need to investigate issues connected with IPFIX. With IGMP being disabled, such messages will not appear.
The above log messages have no impact on functionality.
Please note that its an Warning message and NOT an Error, which can be excluded from the log filter from getting appeared in the logs as a workaround
