■ Timezone Offset—Time difference between the time zone and UTC, in
hours:minutes
■ Access List—Identities of access lists of servers from which the system
does not accept broadcasts
■ ‘Server Source’ Interface—Interface through which responses from the
NTP server are directed; configured through the ntp server source
command, which overrides the interface configured through the ntp
source command.
■ ‘Client Source’ Interface—Interface through which all NTP server
responses are directed; configured through the ntp source command.
■ Source Interface—IP address of the interface to which NTP servers should
send NTP responses
■ Address—IP address of interface
■ Enable—Status of NTP on the interface, On or Off
■ BcastClient—Indication of whether or not this interface accepts
broadcasts from NTP servers, On or Off
■ BcastServer—Indication of whether or not this interface functions as a
broadcast server, On or Off
■ Name—Type of interface and its location
