esp authentication-algorithm
Syntax
esp authentication-algorithm sha1
undo

authentication-algorithm
View
IPsec proposal view
Default level
2: System level
Parameters
sha1
: Uses the SHA1 algorithm, which uses a 160-bit key.
Description
Use the
esp authentication-algorithm
command to specify an authentication algorithm for ESP.
Use the
undo esp authentication-algorithm
command to configure ESP not to perform authentication on
packets.
By default, SHA-1 is used.
You must use both ESP authentication and encryption.
For ESP, you must specify an encryption algorithm, an authentication algorithm, or both. The
undo
esp
authentication-algorithm
command takes effect only if one encryption algorithm is specified for ESP.
