www.dell.com | support.dell.com To disable NTP on an interface, use the following command in the INTERFACE mode: Command Syntax ntp disable Command Mode Purpose INTERFACE Disable NTP on the interface. To view whether NTP is configured on the interface, use the show config command in the INTERFACE mode. If ntp disable is not listed in the show config command output, then NTP is enabled. (The show config command displays only non-default configuration information.) Configure a source IP address for NTP packets By default, the source address of NTP packets is the IP address of the interface used to reach the network. You can configure one interface's IP address to be included in all NTP packets. To configure an IP address as the source address of NTP packets, use the following command in the CONFIGURATION mode: Command Syntax ntp source interface Command Mode Purpose CONFIGURATION Enter the following keywords and slot/port or number information: • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a loopback interface, enter the keyword loopback followed by a number between 0 and 16383. • For a port channel interface, enter the keyword lag followed by a number from 1 to 255 for TeraScale and ExaScale. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information. • For a VLAN interface, enter the keyword vlan followed by a number from 1 to 4094. E-Series ExaScale platforms support 4094 VLANs with FTOS version 8.2.1.0 and later. Earlier ExaScale supports 2094 VLANS. To view the configuration, use the show running-config ntp command (Figure 38) in the EXEC privilege mode. 748 | System Time and Date
