ntp-service manycast-client
Function
The ntp-service manycast-client command configures the NTP manycast client mode.
The undo ntp-service manycast-client command cancels the NTP manycast client mode.
By default, the NTP manycast client mode is disabled.
Format
ntp-service manycast-client [ ip-address | ipv6 [ ipv6-address ] ] [ authentication-keyid key-id | ttl ttl-number | port port-number ] *
undo ntp-service manycast-client [ ip-address | ipv6 [ ipv6-address ] ] [ authentication-keyid key-id | ttl ttl-number | port port-number ] *
Parameters
| Parameter | Description | Value |
|---|---|---|
| ip-address | Specifies a manycast IPv4 address, which is a class D address. |
The default IPv4 address is 224.0.1.1. |
| ipv6 [ ipv6-address ] | Specifies a manycast IPv6 address. |
The default IPv6 address is FF0E::0101. |
| authentication-keyid key-id | Specifies the ID of the authentication key used for sending packets to a manycast server. |
The value is an integer that ranges from 1 to 65535. |
| ttl ttl-number | Specifies the TTL value of a manycast packet. |
The value is an integer ranges from 1 to 255. |
| port port-number | Specifies the port number to transmit NTP manycast message. | The value is 123 or an integer ranging from 1025 to 65535. The default value is 123. |
Usage Guidelines
The local device runs in the manycast client mode, and periodically sends manycast packets to manycast servers. After the local device receives the reply packet sent by a manycast server, the local device establishes dynamic C/S association with the server.
Example
# Configure VLANIF100 to receive NTP manycast packets.
<HUAWEI> system-view [HUAWEI] interface vlanif 100 [HUAWEI-Vlanif100] ip address 10.1.1.1 24 [HUAWEI-Vlanif100] ntp-service manycast-client
# Configure GigabitEthernet0/0/1 to receive NTP manycast packets.
<HUAWEI> system-view [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] undo portswitch [HUAWEI-GigabitEthernet0/0/1] ntp-service manycast-client
