Syntax authentication-key key-id {key key} [hash | hash2] type {des | message-digest}

Context config>system>time>ntp
Platforms Supported on all 7210 SAS platforms as described in this document, including platforms
configured in the access-uplink operating mode
Description This command sets the authentication key ID, type and key used to authenticate NTP PDUs
sent to or received by other network elements participating in the NTP protocol. For
authentication to work, the authentication key ID, type and key value must match.
The no form of this command removes the authentication key.
Parameters key-id — Specifies the authentication key ID that will be used by the node when
key — Specifies the authentication key associated with the configured key ID, the value
hash — Specifies that the key is entered in an encrypted form. If the hash or hash2
hash2 — Specifies that the key is entered in a more complex encrypted form that
type — Specifies if DES or message-digest authentication is used.

transmitting or receiving Network Time Protocol packets.
Entering the authentication-key command with a key ID value that matches an
existing configuration key will result in overriding the existing entry.
Recipients of the NTP packets must have the same authentication key ID, type, and
key value in order to use the data transmitted by this node. This is an optional
parameter.
Values 1 to 255
configured in this parameter is the actual value used by other network elements to
authenticate the NTP packet.
The key can be any combination of ASCII characters up to maximum 32 characters
for message-digest (MD5) or maximum 8 characters for DES (length limits are not
encrypted). If spaces are used in the string, enclose the entire string in quotation
marks (".").
parameter is not used, the key is assumed to be in a non-encrypted, clear text form.
For security, all keys are stored in encrypted form in the configuration file with the
hash or hash2 parameter specified.
involves more variables then the key value alone, this means that hash2 encrypted
variable can't be copied and pasted. If the hash or hash2 parameter is not used, the
key is assumed to be in a non-encrypted, clear text form. For security, all keys are
stored in encrypted form in the configuration file with the hash or hash2 parameter
specified.
Values des — Specifies that DES authentication is used for this key
message-digest — Specifies that MD5 authentication, in
accordance with RFC 2104, is used for this key.
