crypto map ipsec

To define IPSec Phase II Proposal providing encryption and determining authentication algorithm, mode of transaction, and lifetime as parameters, use the crypto map ipsec command in Crypto Map Configuration Mode.

crypto map ipsec

crypto map ipsec { {authentication ( } { ah | } { esp | } { encryption) | } { lifetime ( } { hrs | } { mins | } { secs) } { | pfs } { (group1 | } { group14 | } { group2 | } { group5) | } { lifetime ( } { hrs | } { mins | } { secs)} }
