--- configuration mode command

--- Configuration for IPSec policies

crypto ipsec transform-set myset esp-des esp-md5-hmac

--- Enables the crypto transform configuration mode,

--- where you can specify the transform sets that are used

--- during an IPSec negotiation

crypto map mymap 10 ipsec-isakmp

--- Indicates that IKE is used to establish

--- the IPSec security association for protecting the

--- traffic specified by this crypto map entry

set peer 200121

--- Sets the IP address of the remote end

set transform-set myset

--- Configures IPSec to use the transform-set
