Usage Guidelines

Usage Scenario

For security or source tracing, if a carrier does not want the IP addresses released when users go offline to be immediately assigned to other users, run the access ip-address delayed-release command to configure a delay for IP address release.

Configuration Impact

If a long delay is configured and users frequently go online and offline, most IP addresses are in the delayed release state. As a result, users may not be able to go online within a period of time.

Precautions

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

Example

# Set a delay for IP address release when users go offline to 60s.
