Predefined user roles network-admin Parameters peer: Allows time requests and NTP control queries (such as alarms, authentication status, and time server information) from a peer device and allows the local device to synchronize itself to a peer device. query: Allows only NTP control queries from a peer device to the local device. server: Allows time requests and NTP control queries from a peer device, but does not allow the local device to synchronize itself to a peer device.
undo ntp-service authentication enable Default NTP authentication is disabled. Views System view Predefined user roles network-admin Usage guidelines Enable NTP authentication in networks that require time synchronization security to make sure NTP clients are only synchronized to authenticated NTP servers. To authenticate an NTP server, set an authentication key and specify it as a trusted key. Examples # Enable NTP authentication.
Usage guidelines In a network where there is a high security demand, the NTP authentication feature must be enabled for a system running NTP. This feature enhances the network security by using client-server key authentication, which prohibits a client from synchronizing to a device that has failed the authentication. After you specify an NTP authentication key, use the ntp-service reliable authentication-keyid command to configure the key as a trusted key.
[Sysname-Vlan-interface1] ntp-service broadcast-client Related commands ntp-service broadcast-server ntp-service broadcast-server Use ntp-service broadcast-server to configure the device to operate in NTP broadcast server mode and use the current interface to send NTP broadcast packets. Use undo ntp-service broadcast-server to remove the configuration.
Syntax ntp-service enable undo ntp-service enable Default The NTP service is not enabled. Views System view Predefined user roles network-admin Examples # Enable the NTP service. system-view [Sysname] ntp-service enable ntp-service inbound disable Use ntp-service inbound disable to disable an interface from receiving NTP messages. Use undo ntp-service inbound disable to restore the default.
Use undo ntp-service ipv6 acl to remove the configured NTP service access-control right. Syntax ntp-service ipv6 { peer | query | server | synchronization } acl acl-number undo ntp-service ipv6 { peer | query | server | synchronization } acl acl-number Default The access-control right for the peer devices to access the IPv6 NTP services of the local device is peer.
• ntp-service authentication-keyid • ntp-service reliable authentication-keyid ntp-service ipv6 inbound disable Use ntp-service ipv6 inbound disable to disable an interface from receiving IPv6 NTP messages. Use undo ntp-service ipv6 inbound disable to restore the default. Syntax ntp-service ipv6 inbound disable undo ntp-service ipv6 inbound disable Default All interfaces are enabled to receive IPv6 NTP messages.
Parameters ipv6-multicast-address: Specifies an IPv6 multicast IP address. An IPv6 broadcast client and an IPv6 broadcast server must be configured with the same multicast address. Usage guidelines After you configure this command, the device listens to IPv6 NTP messages with the destination address as the specified multicast address and is synchronized based on the received IPv6 NTP messages.
Examples # Configure the device to operate in IPv6 multicast server mode and send IPv6 NTP multicast messages on VLAN-interface 1 to the multicast address FF21::1, using key 4 for encryption. system-view [Sysname] interface vlan-interface 1 [Sysname-Vlan-interface1] ntp-service ipv6 multicast-server ff21::1 authentication-keyid 4 Related commands ntp-service ipv6 multicast-client ntp-service ipv6 source Use ntp-service ipv6 source to specify the source interface for IPv6 NTP messages.
Examples # Specify the source interface of IPv6 NTP messages as VLAN-interface 1. system-view [Sysname] ntp-service ipv6 source vlan-interface 1 ntp-service ipv6 unicast-peer Use ntp-service ipv6 unicast-peer to specify an IPv6 symmetric-passive peer for the device. Use undo ntp-service ipv6 unicast-peer to remove the IPv6 symmetric-passive peer specified for the device.
Usage guidelines When you specify an IPv6 passive peer for the device, the device and its IPv6 passive peer can be synchronized to each other. If their clocks are in synchronized state, the clock with a high stratum level is synchronized to the clock with a lower stratum level. To synchronize the PE to a PE or CE in a VPN, provide the vpn-instance vpn-instance-name option in the command.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the NTP server belongs, where vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the NTP server is on the public network, do not specify this option. authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the NTP server, where keyid is in the range of 1 to 4294967295. If this option is not specified, the local device and NTP server do not authenticate each other.
Default The maximum number of dynamic NTP sessions is 100. View System view Predefined user roles network-admin Parameters number: Sets the maximum number of dynamic NTP associations allowed to be established, in the range of 0 to 100. Usage guidelines A single device can have a maximum of 128 concurrent associations, including static associations and dynamic associations.
Usage guidelines After you configure this command, the device listens to NTP messages with the destination address as the specified multicast address. If you have configured the device to operate in multicast client mode on an interface with this command, do not add the interface to any aggregate group. To add the interface to an aggregate group, remove the configuration of the command.
Usage guidelines After you configure this command, the device periodically sends NTP messages to the specified multicast address. If you have configured the device to operate in multicast server mode on an interface with this command, do not add the interface to any aggregate group. To add the interface to an aggregate group, remove the configuration of the command.
If the devices in a network cannot synchronize to an authoritative time source, you can select a device that has a relatively accurate clock from the network, and use the local clock of the device as the reference clock to synchronize other devices in the network. Use this command with caution to avoid time errors. Before you execute the command, HP recommends that you adjust the local system time. Examples # Specify the local clock as the reference source, with the stratum level 2.
Related commands • ntp-service authentication enable • ntp-service authentication-keyid ntp-service source Use ntp-service source to specify the source interface for NTP messages. Use undo ntp-service source to restore the default. Syntax ntp-service source interface-type interface-number undo ntp-service source Default No source interface is specified for NTP messages.
ntp-service unicast-peer Use ntp-service unicast-peer to specify a symmetric-passive peer for the device. Use undo ntp-service unicast-peer to remove the symmetric-passive peer specified for the device.
Examples # Specify the device with the IP address of 10.1.1.1 as the symmetric-passive peer of the device, configure the device to run NTP version 4, and specify the source interface of NTP messages as VLAN-interface 1. system-view [Sysname] ntp-service unicast-peer 10.1.1.
Usage guidelines When you specify an NTP server for the device, the device is synchronized to the NTP server, but the NTP server is not synchronized to the device. To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in your command. If you include the vpn-instance vpn-instance-name option in the undo ntp-service unicast-server command, the command removes the NTP server with the IP address of ip-address in the specified VPN.
