vtp Authentication Secret Key

1.3.6.1.4.1.9.9.46.1.9.1.1.3

The device creating or modifying the VTP configuration signs it using the MD5 digest generated from the secret key before advertising it. Other devices in the domain receiving this configuration use the same secret key to accept it if it was correctly signed or drop it otherwise. By default, the object has the value as a zero-length string and this value is read only. It is set to this value automatically when the password (vtpAuthPassword) is set to a zero-length octet string. The secret key can be either generated using the password or configured by the user. Once the secret key is configured by the user, it is stored as a hexadecimal string in the device's configuration and the password is considered to be the secret key's matching password and hidden from the configuration automatically. This object is not allowed to be set at the same time when vtpAuthPassword is set. The secret key is overwritten by a newly generated secret key when the password is re-configured.
