5.3.2.1 Adding a New SNTP Symmetric Key
To add a new key:
1. Select Services > Secure NTP from the main menu tree.
Key ID Displays a Key ID between 1-65534. The Key ID is a abbreviation
allowing the switch to reference multiple passwords. This makes
password migration easier and more secure between the switch
and its NTP resource.
Key Value Displays the authentication value used to secure the credentials of
the server providing system time to the switch.
Trusted Key If a checkmark appears, a trusted key has been associated with a
domain name. A trusted key is added when a public key is known,
but cannot be securely obtained. Adding the trusted key allows
information from the server to be considered secure. The
authentication procedures requires both the local and remote
servers share the same key and key identifier. Therefore, using key
information from a trusted source is important.
CAUTION After an NTP synchronization using a Symmetric Key, the NTP status will not
automatically be updated.
