Network Time Protocol Commands
ntp
Syntax
[
no
]
ntp
Context
config>system>time
Description
This command enables the context to configure Network Time Protocol (NTP) and its operation. This
protocol defines a method to accurately distribute and maintain time for network elements. Furthermore this
capability allows for the synchronization of clocks between the various network elements. Use the no form
of the command to stop the execution of NTP and remove its configuration.
Default
none
authentication-check
Syntax
[
no
]
authentication-check
Context
config>system>time>ntp
Description
This command provides the option to skip the rejection of NTP PDUs that do not match the authentication
key-id, type or key requirements. The default behavior when authentication is configured is to reject all NTP
protocol PDUs that have a mismatch in either the authentication key-id, type or key.
When
authentication-check
is enabled, NTP PDUs are authenticated on receipt. However, mismatches
cause a counter to be increased, one counter for type and one for key-id, one for type, value mismatches.
These counters are visible in a show command.
The
no
form of this command allows authentication mismatches to be accepted; the counters however are
maintained.
Default
authentication-check — Rejects authentication mismatches.
authentication-key
Syntax
authentication-key key-id
{
key key
} [
hash
|
hash2
]
type
{
des
|
message-digest
}
no authentication-key key-id
Context
config>system>time>ntp
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 the command removes the authentication key.
Default
none
