# NTP System Configuration

The NTP System Configuration dialog box displays the system details.

## Procedure

For CiscoView versions earlier than 5.2:

1. Right-click the device. Then select Configure, or double-click the device.

2. Select Protocols from the Category list.

3. Select NTP from the SelectProtocol list, then click the Details button. The NTP Configuration dialog box appears.

4. Select System Configuration from the Category list.

For CiscoView version 5.2 and later:

1. Right-click the device, then select Configure, or double-click the device.

2. Select Protocols from the Category list.

3. Select NTP from the SelectProtocol list. Then click the Details button. The NTP Configuration dialog box appears.

   Note: The left frame in the dialog box displays the categories and the right frame displays category details or a table. If a table is displayed, the variable on which the table is indexed and the key values of the index are listed below the category. Double-click the category to view the table and double-click a key value to view details of a particular row in the table.

   Multiple indexes for a table, if any, are listed below the category in a nested manner. Select a key value to view the rows of the table about that value. Select a key value of the lowest indexing variable to view the details of that particular row.

4. Select System Configuration from the left pane.

The following information appears:

Leap Indicator (cntpSysLeap)

Local Clock Stratum (cntpSysStratum)

Clock Precision (cntpSysPrecision)

Total Round-Trip Delay (cntpSysRootDelay)

Dispersion (cntpSysRootDispersion)

Reference ID of Local Clock (cntpSysRefId)

Local Clock Update Time (cntpSysRefTime)

NTP Server Poll Interval (cntpSysPoll)

Current Synchronization Source (cntpSysPeer)

Current Local Time (cntpSysClock)

### Leap Indicator (cntpSysLeap)

Two-bit code that warns of an impending leap second to be inserted in the NTP timescale.

### Local Clock Stratum (cntpSysStratum)

Stratum of the local clock.

### Clock Precision (cntpSysPrecision)

Signed integer indicating the precision of the system clock, in seconds, to the nearest power of 2. The value is rounded to the next larger power of 2; for example, a 50-Hz (20 ms) or 60-Hz (16.67 ms) power-frequency clock would be assigned the value -5 (31.25 ms), while a 1000-Hz (1 ms) crystal-controlled clock would be assigned the value -9 (1.95 ms).

### Total Round-Trip Delay (cntpSysRootDelay)

Signed fixed-point number that indicates the total round-trip delay. The round-trip delay, in seconds, is in relation to the primary reference source at the root of the synchronization subnet.

### Dispersion (cntpSysRootDispersion)

Maximum error in seconds, in relation to the primary reference source at the root of the synchronization subnet. This object takes only positive values greater than zero.

### Reference ID of Local Clock (cntpSysRefId)

Reference identifier of the local clock.

### Local Clock Update Time (cntpSysRefTime)

Local time when the local clock was last updated. If the local clock has never been synchronized, the value of this object is zero.

### NTP Server Poll Interval (cntpSysPoll)

Interval at which the NTP server polls other NTP servers to synchronize its clock.

### Current Synchronization Source (cntpSysPeer)

Current synchronization source. This object contains the unique association identifier cntpPeersAssocId of the peer acting as the synchronization source. The cntpPeersAssocId is taken from the corresponding peer entry in the cntpPeersVarTable. If there is no peer, the value of this object is 0.

### Current Local Time (cntpSysClock)

Local time as derived from the hardware clock of the machine. Local time increments at intervals depending on the design used.
