> # Configuring an NTP Peer on a C Series Controller (SRC CLI)

> Use the following configuration statements to configure NTP on a C Series Controller to operate in symmetric active mode:

> `
> edit system ntp peer address {
>   version version;
>   prefer;
> }
> `

> To configure NTP to operate in symmetric active mode:

> 1. From configuration mode, access the configuration statement that configures an NTP peer, and specify the IP address or hostname of an NTP peer.
>    `
>    [edit system ntp]
>    user@host# edit peer address
>    `

>    For example, to specify an NTP peer that has an IP address of 192.0.2.40:

>    `
>    [edit system ntp]
>    user@host# edit peer 192.0.2.40
>    [edit system ntp peer 192.0.2.40]
>    user@host#
>    `
> 2. (Optional) Specify the version of NTP to be used for outgoing packets.
>    `
>    [edit system ntp server address ]
>    user@host# set version version
>    `
> 3. (Optional) If you configure more than one peer, specify whether this server is to be contacted first for synchronization.
>    `
>    [edit system ntp server address ]
>    user@host# set prefer
>    `
