For example, to clear only the dynamic buffer, enter the clear logging command at the Privileged EXEC level. PowerConnect# clear logging dynamic-buffer Syntax: clear logging [dynamic-buffer | static-buffer] Specify the dynamic-buffer keyword to clear the dynamic buffer, or the static-buffer keyword to clear the static buffer. If you do not specify a buffer, both buffers are cleared. Managing switch fabric modules This section provides information about how to manage high speed switch fabric modules. NOTE In CLI output, high-speed modules are referred to as generation 2 (G2) modules. High speed switch fabric (HSF) modules can operate in normal mode (3.125 Gbps) or turbo mode (6.25 Gbps). HSF modules will boot in turbo mode only if all active interface modules are either NI-MLX-10Gx8-M modules or NI-MLX-48-T-A modules. The system selects the operating mode for switch fabric modules at startup, or when the first switch fabric or interface module is installed. The system uses this mode for all modules that are subsequently installed. NOTE Changes to the switch fabric operating mode do not take effect until after a system reload. Standard and high-speed switch fabric modules are interoperable, with the following restrictions: • The system blocks discovery of any standard switch fabric module if you have issued the system-init block-g1-sfm command. Refer to "Blocking discovery of G1 switch fabric modules" on page 109. • If the system is operating in turbo mode, standard switch fabric modules and standard interface modules are automatically blocked. • If there are any active G1 switch fabric modules, G2 interface modules are blocked. • If there are any active G2 interface modules, G1 switch fabric modules are blocked. Forcing HSF modules to operate in normal mode If necessary, you can configure HSF modules to operate in normal mode using the system-init fabric-data-mode force normal command. PowerConnect(config)# system-init fabric-data-mode force-normal Syntax: [no] system-init fabric-date-mode force-normal If you remove the forced normal condition using the no version of this command, you must enter the write-memory command and restart the router. 106 PowerConnect B-MLXe Hardware Installation Guide 53-1002111-01
