Impact

Possible loss of client connectivity or random errors possibly resulting in cores. Traffic disrupted while tmm restarts.

Conditions

This can occur if the interface is associated with a non-default route domain.

Workaround

None

Fix Information

Long interface names no longer cause issues.
