The Phase-1 Internet Key Exchange Tunnel Table.
There is one entry in this table for each active
IKE tunnel. This table is an extension to
cifIkeTunnelTable defined in CISCO-IKE-FLOW-MIB.
Some information in this table is also present in
the cisgIpsSgTunnelTable, but the table is indexed
differently so that the rows in this table are
grouped/ordered by domain of interpretation (DOI).
