Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information By default, the system implements an optimized flush mechanism for PVST+. This
implementation helps in flushing the MAC addresses only when necessary (and less
often) allowing for faster convergence during topology changes. However, if a
standards-based flush mechanism is needed, you can turn this knob command on
to enable flushing MAC addresses after receiving every topology change
notification.
