Configuring the Network Clock
To configure the network clock for a Cisco ASR 1000 Series Aggregation Services Router, perform the
following procedure:
Network clocking is not supported on the SPA-2CHT3-CE-ATM.
Note
SUMMARY STEPS
1. Router(config)# [no] network-clock select priority {interface | controller | slot | system type interface
name [ global ][ local ]}
2. Router(config)# [no] network-clock revertive
3. Router(config)#
controller sonet slot/subslot/port
4. Router(config-controller)# clock source {line | internal}
5.
Router(config-controller)# exit
6. Router(config)# exit
7.
Router# show network-clocks
8. Router# debug network-clock
9.
Router# debug network-clock redundancy
DETAILED STEPS
Purpose Command or Action
Selects an interface or controller and configures it as a network clock source
with a particular priority. Router(config)# [no] network-clock
select priority {interface | controller
Step 1
| slot | system type interface name
[ global ][ local ]}
•
system
—
Required for platforms that have an internal clock generator. Not
applicable to the Cisco ASR 1000 Series Aggregation Services Routers.
•
priority
—
Configures the priority of the network clock source. Values
range from 1 to 6.
• type — Interface type that needs to be configured like Gigabitethernet, POS,
CEM and so on.
•
interface name
—
Configures the network clock source to the selected
interface.
•
global
—
Configures the network clock such that it uses a global
configuration.
• local — Configures the network clock such that it uses a local configuration.
Only one source can be configured at a
time.
Note
Configures the revertive mode on the network clock. Router(config)# [no] network-clock
revertive
