Dell Force10 Z9000 FTOS Command Line Reference Guide for the Z9000 System FTOS - Page 1005

Usage Information Version 8.2.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 6.5.1.0 Introduced the hardware shutdown-on-violation option. Introduced on the S-Series. Introduced on the C-Series. Introduced on the E-Series. On an MSTP switch, a port configured as an edge port immediately transitions to the forwarding state. You should only configure ports connected to end-hosts as edge ports. Consider an edge port similar to a port with spanning-tree portfast enabled. If you do not enable shutdown-on-violation, BPDUs are still sent to the RPM CPU. tc-flush-standard Enable the MAC address flushing after receiving every topology change notification. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax Defaults Command Modes Command History tc-flush-standard To disable, use the no tc-flush-standard command. Disabled. CONFIGURATION Version 8.3.11.1 Version 8.3.7.0 Version 7.6.1.0 Version 7.5.1.0 Version 6.5.1.0 Introduced on the Z9000. Introduced on the S4810. Introduced on the S-Series. Introduced on the C-Series. Introduced 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, this knob command can be turned on to enable flushing MAC addresses after receiving every topology change notification. 1005
