hash-control
Syntax hash-control [read-version {1 | 2 | all}] [write-version {1 | 2}]
no hash-control
Context config>system>security
Description Whenever the user executes a save or info command, the system will encrypt all passwords,
keys, and so on for security reasons. At present, two algorithms exist.
The first algorithm is a simple, short key that can be copied and pasted in a different location
when the user wants to configure the same password. However, because it is the same
password and the hash key is limited to the password/key, it is obvious that it is the same key.
The second algorithm is a more complex key, and cannot be copied and pasted in different
locations in the configuration file. In this case, if the same key or password is used repeatedly
in different contexts, each encrypted (hashed) version will be different.
Default all — read-version set to accept both versions 1 and 2
Parameters read-version {1 | 2 | all} — when the read-version is configured as “all,” both versions 1
and 2 will be accepted by the system. Otherwise, only the selected version will be
accepted when reading configuration or exec files. The presence of incorrect hash
versions will abort the script/startup.
write-version {1 | 2} — selects the hash version that will be used the next time the
configuration file is saved (or an info command is executed). Be careful to save the
read and write version correctly, so that the file can be properly processed after the
next reboot or exec.
source-address
Syntax source-address
Context config>system>security

sent by the application.
application
Syntax application app [ip-int-name | ip-address]
