When you clear log entries, you can selectively clear the either buffer, or you can clear both. 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:
•

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
The system blocks discovery of any standard switch fabric module if you have issued the
system-init block-g1-sfm command. Refer to
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.
