ip used-threshold(IP address pool view)

Function

The ip used-threshold command configures upper and lower address usage thresholds of a dynamic address pool.

The undo ip used-threshold command restores the default configuration.

By default, the upper threshold for address segment application is 80%, and the lower threshold for address segment release is 20%.

This command is supported only on the NetEngine 8000 F1A.

Format

ip used-threshold upper-limit upper-value lower-limit lower-value

undo ip used-threshold [ upper-limit [ upper-value ] [ lower-limit [ lower-value ] ] ]

Parameters

Parameter	Description	Value
lower-limit lower-value	Specifies a lower threshold for address segment release, in percentage. lower-limit must be smaller than upper-limit.	The value is an integer ranging from 0 to upper-limit-1.
upper-limit upper-value	Specifies an upper threshold for address segment application, in percentage.	The value is an integer ranging from 1 to 100.

Usage Guidelines

Usage Scenario

To configure upper and lower address usage thresholds of a dynamic address pool, run the ip used-threshold command. Then the address segments in the dynamic address pool can be dynamically applied for or released.

The BRAS checks the dynamic address pool usage every 10 minutes. If the BRAS detects that the dynamic address pool usage reaches the upper threshold, the BRAS applies to the RADIUS server for new address segments. If the BRAS detects that the dynamic address pool usage falls below the lower threshold, the BRAS applies to the RADIUS server for releasing address segments.

Precautions

In VS mode, this command is supported only by the admin VS.

If the ip used-threshold command is run more than once, the latest configuration overrides the previous one.

Example

# Configure an upper threshold 90% for address segment application and a lower threshold 30% for address segment release.
