Nortel Business Secure Router 222 Configuration — Basics
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. Table 60 describes the
fields in this tab.
Figure 77 VPN SA Monitor
Table 60 describes the fields in Figure 77.
Note: 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 time out until the SA lifetime period
expires. See the section “Keep Alive” on page 214 about keep alive to
have the Business Secure Router renegotiate an IPSec SA when the SA
lifetime expires, even if there is no traffic.
