You can, at any time, modify the rate limit parameters for pre-defined
applications. Besides the pre-defined applications, you can also configure rate
limiting for other applications.
You can, at any time, view configuration information for the rate limiting feature.
1 Enable the rate limiting configuration mode (refer to Section 4.3.6.2.1)
2 You can now execute any of the following tasks:
» Modify default rate limiting configuration for pre-defined applications (refer
to Section 4.3.6.2.2)
» Configure rate limiting for user-defined applications (refer to
Section 4.3.6.2.3)
» Disable rate limiting for specific applications (refer to Section 4.3.6.2.4)
You can, at any time, enable or disable rate limiting (refer to Section 4.3.6.2.5). In
addition, you can also display configuration information for the rate limiting
feature (refer to Section 4.3.6.2.6).
NOTE
Rate limiting for pre-defined applications is only configured for control traffic from FTP, Telnet, and
TFTP applications. You need to configure rate limiting separately for data traffic from FTP, Telnet,
and TFTP. For details, refer to “Configuring Rate Limiting for User-defined
Applications” on page 189
.
IMPORTANT
100 Kbps is the default rate limit that is configured for pre-defined and user-defined applications. In
addition, 100 Kbps is the default rate limit that is specified for all other applications that may send
packets to the NPU (but are not in the list of pre-defined or user-defined applications).
If you disable rate limiting for a specific pre-defined or user-defined application, the rate limit that
you have configured for all other applications will be applicable for the application (for which
rate-limiting is disabled.
To configure rate limiting for the NPU:
