17.5 Viewing SA Monitor
Click Security > VPN > Monitor to open the screen as shown. Use this screen to display and
manage active VPN connections.
A Security Association (SA) is the group of security settings related to a specific VPN tunnel. This
screen displays active VPN connections. Use Refresh to display active VPN connections. This
screen is read-only. The following table describes the fields in this tab.
When there is outbound traffic but no inbound traffic, the SA times out automatically after two
minutes. A tunnel with no outbound or inbound traffic is "idle" and does not timeout until the SA
lifetime period expires. See Section 17.6.6 on page 215 on keeping alive to have the Device
renegotiate an IPSec SA when the SA lifetime expires, even if there is no traffic.
