DESCRIPTION
|
||||
"The MIB module for management of network clock distribution
|
||||
and the Network Clock Distribution Protocol (NCDP) in Cisco
|
||||
devices.
|
||||
|
||||
In the context of this MIB 'network clock' refers to the
|
||||
clock signal that is used to time the physical interfaces.
|
||||
Network clock distribution refers to the distribution of a
|
||||
clock signal through a device and between devices for use
|
||||
by the physical interfaces. (See Bell Communications
|
||||
Research, GR-1244-CORE, 'Clocks for the Synchronized
|
||||
Network: Common Generic Criteria' and Bell Communications
|
||||
Research, GR-436-CORE, 'Digital Network Synchronization
|
||||
Plan').
|
||||
|
||||
NCDP is used to configure the network clocking hardware of
|
||||
the platform on which an NCDP entity exists. The underlying
|
||||
network clocking hardware in turn distributes a clock signal
|
||||
through the device for use by the physical interfaces. When
|
||||
all of the interfaces that support synchronous clock
|
||||
recovery in a network are timed to one master clock signal,
|
||||
the network is said to be synchronized.
|
||||
|
||||
NCDP protocol entities residing on adjacent devices
|
||||
cooperate through the exchange of protocol messages to
|
||||
construct a spanning network clock distribution tree.
|
||||
The tree preserves the synchronous digital hierarchy.
|
||||
|
||||
After NCDP has determined that its algorithm has converged
|
||||
it superimposes the clock distribution tree on the
|
||||
underlying network and the result is a synchronized
|
||||
network."

"The maximum possible height of a network clock distribution

maximum diameter of the network of devices that are
|

participating in NCDP.) If all of the nodes in the network
|

are participating in the protocol then the maximum height of

the network clock distribution tree is exactly the maximum
|

diameter of the network. If a proper subset of the nodes
|

are participating in the NCDP then the maximum height of a
|

network clock distribution tree is the maximum diameter of
|

the subnetwork induced by the removal of the

non-participating nodes and their associated links.
|

|

The NCDP protocol entity uses the value of this object to

determine when the NCDP algorithm has converged. All
|
||||
devices participating in NCDP within the bounds of the
|
||||
network must use the same value for maximum network diameter
|

for the NCDP algorithm to operate properly. If the value of
|

this object is set too small the resultant network may
|

exhibit unstable clocking characteristics and may constantly
|

switch clock sources. If the value is much larger than the
|

network diameter, the algorithm will take longer to declare
|
||||
convergence than if the diameter were set closer to the
|
||||
actual maximum network diameter, the result being that it

will take longer for the network to resynchronize after a
|

switchover to a secondary clock source located on a

secondary device.

The message interval directly affects the convergence time

the time a configuration PDU is spent being processed in

|
||||
|

A source of network clock for the device may be an

oscillator local to the device, a Building Integrated Timing

Supply (BITS) port or an interface that supports synchronous

clock recovery.
|

(BITS is explained in more detail in Bell Communications
|

Research, GR-436-CORE, 'Digital Network Synchronization

|
||||
|
||||
The NCDP protocol entity selects one entry in this table to
|
||||
advertise as the best available clock source for the device.
|
||||
Cooperating NCDP protocol entities select the best available
|
||||
clock source among those advertised within the cooperating
|
||||
group and build a clock distribution tree rooted at that
|
||||
clock source. When the value of cncRootClockSource is used
|
||||
as an index into this table and the indicated clock source
|
||||
has cncNcdpBestClockSource with value 'true' then the
|
||||
indicated clock source is the root of some clock
|
||||
distribution tree. If only one such root exists on all
|
||||
participating devices in the network, then it is the root of
|
||||
a network wide clock distribution tree.
|
||||
|
||||
When the managed system initializes it creates a row for the
|
||||
device's default source of network clock. This row cannot be
|
||||
destroyed by a management station. Within this row a write
|
||||
operation is only allowed on the cncNcdpPriority object; only
|
||||
read operations are allowed on all other columnar objects
|
||||
within this specific row. The status of this row is always
|
||||
active. The default source can always be found by issuing a
|
||||
read operation on the row within cncManualSourceTable indexed
|
||||
by 'default' (as the value of cncManualSourcePriority). The
|
||||
cncManualSourceId object contains the entPhysicalIndex of the
|
||||
default source of network clock and identifies it within this
|
||||
table.
|
||||
|
||||
Other rows are created or destroyed by a management station
|
||||
or through the device's local management interface when a
|
||||
source of network clock is configured or removed. When a
|
||||
management station creates a row it creates it explicitly
|
||||
using RowStatus with either createAndGo or createAndWait.
|
||||
A row is not made active until all read-create objects not
|
||||
having default values are properly initialized.
|
||||
|
||||
The values of cncNcdpPriority, cncNcdpStratum and
|
||||
cncNcdpPRSReference collectively describe a source of network
|

clock, that is they are three components of a vector used as
