Configure IPsec Transforms and Protocols
A transform set represents a certain combination of security protocols and algorithms. During IKE
negotiation, the peers agree to use a particular transform set for protecting data flow.
During IKE negotiations, the peers search in multiple transform sets for a transform that is the same at
both peers. When such a transform set is found, it is selected and applied to the protected traffic as a part
of both peers’ configurations.
