7210 SAS-MXP, R6, R12, S, SX, T BASIC SYSTEM
CONFIGURATION GUIDE RELEASE 22.9.R1
System management
Description
This command is used when the node should operate in client mode with the NTP server specified in the
address field of this command.
Up to five NTP servers can be configured.
If the internal PTP process is to be used as a source of time for System Time and OAM time then it must
be specified as a server for NTP. If PTP is specified then the prefer parameter must also be specified.
Once PTP has established a UTC traceable time from an external grandmaster then it shall always be the
source for time into NTP even if PTP goes into time holdover.
Note:
Use of the internal PTP time source for NTP will promote the internal NTP server to stratum 1
level. This may impact the NTP network topology.
The no form of this command removes the server with the specified address from the configuration.
Parameters
ip-address
Specifies the IP address of a node that acts as an NTP server to this network element.
Values a.b.c.d
ptp
Keyword to configure the internal PTP process as a time server into the NTP process. The
prefer keyword is mandatory with this server option. The ptp keyword is supported only on
the 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-Sx/S 1/10GE (standalone),
and 7210 SAS-T.
key-id key-id
Specifies the configured authentication key and authentication type used by this node
to transmit NTP packets to an NTP server. If an NTP packet is received by this node,
the authentication key ID, type, and key value must be valid otherwise the packet will be
rejected and an event/trap generated.
Values 1 to 255
version version
Specifies the NTP version number that is expected by this node.
Default 4
Values 2 to 4
prefer
Specifies the preferred peer. When configuring more than one peer, one remote system
can be configured as the preferred peer. When a second peer is configured as preferred,
the new entry overrides the old entry.
