Security Association (SA) table. Each entry in the table is a
Security Association. SA's are associated with a single IPSec
tunnel or transport and indexed accordingly. SA's associated
with a tunnel will have the same ifIndex and name as the tunnel.
SA's associated with a transport have a zero ifIndex and the
same name as the transport.
Dynamic site-to-site and dialin-client tunnels have dynamic
SA's created dynamically by ISAKMP. Dialin-group tunnels
do not have associated SA's since these represent a group of
dialin-client tunnels which individually have SA's. Static
tunnels have static SA's created manually.
