The message types that appear in the static buffer do not appear in the dynamic buffer. The dynamic buffer
contains up to the maximum number of messages configured for the buffer (50 by default), then begins removing
the oldest messages (at the bottom of the log) to make room for new ones.
The static and dynamic buffers are both displayed when you display the log.
When you clear log entries, you can selectively clear the static or dynamic buffer, or you can clear both. For
example, to clear only the dynamic buffer, enter the following command at the Privileged EXEC level:
NetIron# clear logging dynamic-buffer
Syntax:
clear logging [dynamic-buffer | static-buffer]
You can 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 the Cooling System
This section provides configuration, management, and monitoring information about the NetIron MLX Series
cooling system.
Configuring the Cooling System
The NetIron MLX Series router provides default settings for all cooling system parameters. Therefore, no initial
configuration of the cooling system is necessary. If desired, you can change the settings of the following cooling
system parameters:
•
Low and high temperature thresholds for modules and fan speeds
•
Interval at which the system polls the temperature sensors on the module for a reading
Changing Temperature Thresholds For Modules and Fan Speeds
The NetIron MLX Series cooling system includes fans that operate at speeds of low, medium, medium-high, and
high. In general, each fan speed, except for low, has a low and high temperature threshold associated with it as
shown in Figure 5.1. The low fan speed has a high temperature threshold only.
