19.15 Viewing SA Monitor
Click VPN and Monitor to open the SA Monitor 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
the Keep Alive section on keep alive to have the Prestige
renegotiate an IPSec SA when the SA lifetime expires, even if there is no traffic.
