security vpn ipsec esp-group <name> proposal <num> hash <hash>

Specifies the hash algorithm for an ESP proposal.

set security vpn ipsec esp-group name proposal num hash hash
delete security vpn ipsec esp-group proposal num hash
show security vpn ipsec esp-group proposal num hash

The default is sha1.

name
The name to be used to refer to the ESP configuration.
proposal
An integer uniquely identifying a proposal to be used in IKE Phase 2 negotiation.
hash
The hash algorithm to be used. Supported values are as follows:

md5— MD5 hash message authentication code (HMAC).

null— No separate authentication code.

sha1— SHA1 HMAC (default).

sha1_160—SHA1_160 bit hash.

sha2_256—SHA2_256_128 HMAC

sha2_384—SHA2_384_192 HMAC

sha2_512—SHA2_512_256 HMAC

Configuration mode
