CLI Guide

• If a BPDU is received from a remote device, BPDU guard places the port in an
Err-Disabled Blocking state and no traffic is forwarded on the port.
• If no BPDU is received from a remote device, loop guard places the port in a
Loop-Inconsistent Blocking state and no traffic is forwarded on the port.

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 RSTP. This
implementation helps in flushing 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 this knob command
to enable flushing MAC addresses after receiving every topology change
notification.
