sha1: Uses the HMAC-SHA1 algorithm, which uses a 160-bit key.
sha256: Uses the HMAC-SHA256 algorithm, which uses a 256-bit key.
sha384: Uses the HMAC-SHA384 algorithm, which uses a 384-bit key.
sha512: Uses the HMAC-SHA512 algorithm, which uses a 512-bit key.
Usage guidelines
In non-FIPS mode, you can specify multiple ESP authentication algorithms for one IPsec transform
set, and the algorithm specified earlier has a higher priority.
For a manual or IKEv1-based IPsec policy, the first specified ESP authentication algorithm takes
effect. To make sure an IPsec tunnel can be established successfully, the IPsec transform sets
specified at both ends of the tunnel must have the same first ESP authentication algorithm.
Examples
# Configure the IPsec transform set tran1 to use the HMAC-SHA1 algorithm as the ESP
authentication algorithm.
