<Sysname> system-view
[Sysname] ipsec transform-set tran1
[Sysname-ipsec-transform-set-tran1] encapsulation-mode transport
Related commands
ipsec transform-set
esn enable
Use esn enable to enable the Extended Sequence Number (ESN) feature.
Use undo esn enable to disable the ESN feature.
Syntax
esn enable [ both ]
undo esn enable
Default
ESN is disabled.
Views
IPsec transform set view
Predefined user roles
network-admin
Parameters
both: Specifies IPsec to support both extended sequence number and traditional sequence number.
If you do not specify this keyword, IPsec only supports extended sequence number.
Usage guidelines
The ESN feature extends the sequence number length from 32 bits to 64 bits. This feature prevents
the sequence number space from being exhausted when large volumes of data are transmitted at
high speeds over an IPsec SA. If the sequence number space is not exhausted, the IPsec SA does
not need to be renegotiated.
This feature must be enabled at both the initiator and the responder.
Examples
# Enable the ESN feature in the IPsec transform set tran1.
<Sysname> system-view
[Sysname] ipsec transform-set tran1
[Sysname-ipsec-transform-set-tran1] esn enable
Related commands

esp authentication-algorithm

Use undo esp authentication-algorithm to restore the default.
Syntax
In non-FIPS mode:
esp authentication-algorithm { aes-xcbc-mac | md5 | sha1 | sha256 | sha384 | sha512 | sm3 } *
