Default Command Mode Usage Information Example 8 CONFIGURATION The no version of this command resets the value to the default. OS10(config)# ntp master 6 Supported Releases 10.2.0E or later ntp server Configures an NTP time-serving host. Syntax Parameters ntp server {hostname | ipv4-address | ipv6-address} [key keyid] [prefer] • hostname - Enter the host name of the server. • ipv4-address | ipv6-address - Enter the IPv4 address in A.B.C.D format or IPv6 address in A::B format of the NTP server. • key keyid - (Optional) Enter the NTP peer key ID, from 1 to 4294967295. • prefer - (Optional) Configures this peer to have priority over other servers. Default Command Mode Usage Information Example Not configured CONFIGURATION You can configure multiple time-serving hosts. From these time-serving hosts, the system chooses one NTP host to synchronize with. To determine which server to select, use the show ntp associations command. Dell EMC recommends limiting the number of hosts you configure, as many polls to the NTP hosts can impact network performance. OS10(config)# ntp server eureka.com Supported Releases 10.2.0E or later ntp source Configures an interface IP address to include in NTP packets. Syntax Parameters ntp source interface interface - Set the interface type: • ethernet node/slot/port[:subport] - Enter the Ethernet interface information. • port-channel id-number - Enter the port-channel number, from 1 to 128. • vlan vlan-id - Enter the VLAN number, from 1 to 4093. • loopback loopback-id - Enter the Loopback interface number, from 0 to 16383. • mgmt node/slot/port - Enter the Management port interface information. Default Command Mode Usage Information Not configured CONFIGURATION The no version of this command removes the configuration. System management 127
