As I suspected, the message is not significant as it does not show the actual state of the
interface. As a matter of fact, that command is completely irrelevant for monitoring the
status of the interface or of the IMA group. Therefore, it cannot even be consider a
cosmetic bug, but simply another instance of the multiple IOS commands that, even though available, don't have any implication in the correct functionality of a feature (the IMA circuit in our particular case)
In an IMA circuit, the individual interfaces don't record any statistics, as they are no
longer considered independent, but part of a group instead. For that reason, "show atm
int atmx/y" or "show int atmx/y" don't show (and are not supposed to show) any traffic
statistics.
For troubleshooting or monitoring IMA circuits we can use the commands below:
show int atmx/imay
show ima int atmx/y
show ima int atmx/y detail
show ima int atmx/imay
That line is a bogus message from the IOS. Actually, that command is not used for troubleshooting/monitoring IMA circuits.
