Item	Description
-i	Initiation flag. If the -i flag is not used, all the tunnels in the tunnel database (or those listed with the -t flag) will be activated. If the -i flag is used, only the tunnels whose tunnel definitions status in the tunnel database "active" will be activated.
-I	If the -I flag is specified, manual tunnels will be activated.
-t	If the -t flag is specified, only the tunnel(s) that follows this flag will be activated. If the -t flag is not used, all tunnel(s) currently defined in the tunnel database will be activated. The tid_list can be a single tunnel ID or a sequence of tunnel IDs separated by "," or "-" (1, 3, 5-7).
-v	The IP version of the tunnels to be activated. The value of 4 specifies IP version 4 tunnels. The value of 6 specifies IP version 6 tunnels. If the -v flag is not used, all tunnels for IP version 4 and IP version 6 will be activated.
