Usage guidelines

When RSVP authentication is enabled, the device dynamically establishes security associations when receiving and sending RSVP messages to record the message sequence numbers, which are used in RSVP authentication.

To release memory resources, each security association has an idle timeout. When a security association is idle for the specified timeout time, the device deletes the security association. When the device sends or receives an authenticated RSVP message, it resets the idle timeout timer for the corresponding security association.

The RSVP authentication idle timeout can be configured in the following views:

An RSVP security association established by using the authentication key configured in a view uses the idle timeout configured in the same view.

A modification to the idle timeout affects only security associations established after the modification. To apply the modification to existing security associations, you must execute the reset rsvp authentication command to delete and then re-establish the security associations.

Examples

# Set the idle timeout for RSVP security associations to 100 seconds on VLAN-interface 10.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] rsvp authentication lifetime 100
