Description: This object is the desired state of the tunnel and is similar to interface administrative state. The default is 'up(1)'. When the ipsecTunnelAdminStatus is set to 'up(1)' for a dialin parent tunnel, it enables remote clients in this group to connect to the VPN gateway. When the ipsecTunnelAdminStatus is set to 'down(2)' for a dialin parent tunnel, it disables remote clients in this group from connecting to the VPN gateway. When tunnelAdminStatus is set to up for siteToSiteStatic, it enables use of statically configured SAs. Setting it to down, effectively disables use of statically configured SAs. When tunnelAdminStatus is set to up for siteToSiteDynamic, it enables the VPN gateway to start establishments of SAs via ISAKMP. If the ISAKMP failed to setup SA (for example when the peer is not ready) it will periodically retry SA establishment indefinetly until it succeeds. Setting it to down, disables initiation of SAs and it also disables responding to remote ISAKMP initiation requests.
