Crypto Transform Set Configuration Mode Commands The Crypto Transform Set Configuration Mode is used to configure properties for system transform sets. Transform Sets are used to define IPSec security associations (SAs). IPSec SAs specify the IPSec protocols to use to protect packets. Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s). end Exits the current configuration mode and returns to the Exec mode. Product All Privilege Security Administrator, Administrator Syntax end Usage Use this command to return to the Exec mode. exit Exits the current mode and returns to the parent configuration mode. Product All Privilege Security Administrator, Administrator Syntax exit Usage Use this command to return to the parent configuration mode. mode Configures the IPSec encapsulation mode. Product PDSN, HA, GGSN, PDIF Privilege Security Administrator, Administrator Syntax mode { transport | tunnel } mode transport Specifies that the transform set only protects the upper layer protocol data portions of an IP datagram, leaving the IP header information unprotected. Default: Disabled Important: This mode should only be used if the communications end-point is also the cryptographic end-point. mode tunnel Specifies that the transform set protects the entire IP datagram. This mode should be used if the communications end-point is different from the cryptographic end-point as in a VPN. Default: Enabled Usage This command specifies the encapsulation mode for the transform set. Example The following command configures the transforms set’s encapsulation mode to transport: mode transport
