Configuration of the aging timeout period on a user-defined service of the USG9520

29

You can set the session timeout period of a user-defined port by configuring the persistent connection function on the USG9520. The operation is as follows:
1. In the user view, run the system-view command to enter the system view.
2. Run the security-policy command to enter the security policy view.
3. Run the rule name rule-name command to create a security policy rule and enter the rule view.
4, Run the long-link enable command to enable the persistent connection function.
5. Run the long-link aging-time interval command to set the aging time for persistent connections.

What is the timeout period for LACPDUs
You can configure a switch to send an LACPDU every 1 or 30 seconds. The two sending intervals are defined in IEEE 802.3ad. You can run the lacp timeout { fast | slow } command to set the timeout period for receiving LACPDUs on an interface. After this command is used, the local end informs the peer end of the timeout period through LACPDUs. If fast is configured, the peer end sends LACPDUs every one second. If slow is configured, the peer end sends LACPDUs every 30 seconds. The timeout period of LACPDUs is three times the interval for sending LACPDUs. That is, if fast is configured, the timeout period for receiving LACPDUs is 3 seconds. If slow is configured, the timeout period for receiving LACPDUs is 90 seconds. You can configure different timeout periods on the two ends. To facilitate maintenance, however, you are advised to configure the same timeout period on both ends.

Configuring the IPSec SA lifetime on the firewall
Configure the IPSec SA lifetime on the USG. Configure the IPSec VPN SA lifetime. 1. Configure IKE SA hard lifetime. You can configure per-SA IKE lifetime, but cannot configure a global IKE lifetime. system-view //Access the system view. ike proposal proposal-number //Access the IKE proposal view. sa duration seconds //Configure the IKE SA hard lifetime. Notes for configuring IKE SA lifetime: a) If the hard lifetime expires, the IKE SA will be deleted and re-negotiated. The IKE negotiation involves DH calculation and may take a long time. To ensure the secure communications, you are advised to set the lifetime to a value larger than 600 seconds. b) When the soft lifetime expires, a new SA is negotiated to replace the original SA. Before the new SA is negotiated, the original SA is still in use. After the new SA is established, the new SA is used, and the original SA will be automatically deleted when the hard lifetime expires. The default IKE SA hard lifetime is 86,400 seconds (a day). 2. Configure IKE SA soft lifetime. system-view //Access the system view. ike peer peer-name //Access the IKE peer view. sa soft-duration time-based buffer seconds //Configure the IKE SA soft lifetime. The configuration applies only to IKEv1. a) By default, the soft lifetime is 9/10 of the hard lifetime. When the soft lifetime expires, a new SA is negotiated to replace the original SA. b) If the soft lifetime is specified and the hard lifetime is greater than the soft lifetime by more than 10s, the specified soft lifetime applies; otherwise, the default soft lifetime applies. display ike proposal //Display the configured IKE SA hard lifetime.

Telnet timeout period configuration method on an AR router
In the user interface view, run the idle-timeout < minutes > [< seconds >] command to set user connection timeout period. By default, the user connection timeout period is five minutes. If the period is set to 0 or the value is too long, a terminal will hang in login state, which poses a security risk. You are advised to run a lock command to lock the current connection.

Configure the connection timeout period for Telnet users on S series switches configured with AAA authentication
In general, you can run the idle-time out command in the VTY interface view of an S series switch (except the S1700 switch) to configure the connection timeout period for Telnet users. However, when AAA authentication is configured, the value of the idle-timeout parameter set in the VTY interface view is invalid. The value of the idle-timeout parameter set in the AAA view takes effect.
