The NTP Filter Register dialog box displays details of the filter register table.
For CiscoView versions earlier than 5.2:
Right-click the device. Then select Configure, or double-click the device.
Select Protocols from the Category list.
Select NTP from the SelectProtocol list. Then click the Details button. The NTP Configuration dialog box appears.
Select Filter Register from the Category list.
For CiscoView version 5.2 and later:
Right-click the device, then select Configure, or double-click the device.
Select Protocols from the Category list.
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 the 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.
Select Filter Register from the left pane.
The following information appears:
Peer
Association ID (cntpPeersAssocId)
Filter
Index (cntpFilterIndex)
Peer
Clock Offset (cntpFilterPeersOffset)
Peer
Clock Round-trip delay (cntpFilterPeersDelay)
Peer
Clock Dispersion (cntpFilterPeersDispersion)
Integer value greater than 0 that uniquely identifies the peer with which the local NTP server is associated.
Integer value in the specified range that is used to index the table. The size of the table is fixed at 8. Each entry identifies a particular reading of the clock filter variables in the shift register.
Entries are added starting at index 1. The index wraps back to 1 when it reaches 8. When the index wraps back, the new entries overwrite the old entries effectively deleting the old entry.
Offset of the peer clock relative to the local clock in seconds.
Round-trip delay of the peer clock relative to the local clock over the network path between them, in seconds. This variable can take on both positive and negative values, depending on clock precision and skew-error accumulation.
Maximum error of the peer clock relative to the local clock over the network path between them, in seconds. Only positive values are possible.
