System Command Reference
382 Basic System Configuration Guide
Context config>system>time>ntp
Description This command configures the node to assume the role of an NTP server. Unless the server command
is used, this node will function as an NTP client only and will not distribute the time to downstream
network elements.
Default no ntp-server
Parameters authenticate — If specified, makes authentication a requirement. If authentication is required, the
authentication key-id received in a message must have been configured in the
authentication-key command, and that key-id type and key value must also match.
The authentication key from the received messages will be used for the transmitted messages.
peer
Syntax peer {ip-address | ipv6-address} [key-id key-id] [version version] [prefer]
no peer ip-address
Context config>system>time>ntp
Description Configuration of an NTP peer configures symmetric active mode for the configured peer. Although
any system can be configured to peer with any other NTP node it is recommended to configure
authentication and to configure known time servers as their peers.
The no form of the command removes the configured peer.
Parameters ipv6-address — Configure the IPv6 address of the peer that requires a peering relationship to be
set up. The ipv6 is applicable to the 7750 SR and 7950 XRS only.
Default None
Values x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x [0 to FFFF]H
d [0 to 255]D
ip-address — Configure the IP address of the peer that requires a peering relationship to be set up.
This is a required parameter.
Default None
Values Any valid IP-address
key-id key-id — Successful authentication requires that both peers must have configured the
same authentication key-id, type and key value.
