tc-flush-standard Enable the MAC address flushing after receiving every topology change notification. Syntax tc-flush-standard To disable, use the no tc-flush-standard command. Defaults Disabled Command Modes CONFIGURATION Command History Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module Usage Information By default, FTOS implements an optimized flush mechanism for MSTP. This 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 on the knob command to enable flushing MAC addresses after receiving every topology change notification.
