Verifying the Network Synchronization Configuration

Use the following commands to verify the network synchronization configuration:

Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide
12
Router(config)# network-clock wait-to-restore 10 global
The following example shows how to configure the wait-to-restore timer in the interface
configuration mode:
Router(config)# interface gigabitethernet 0/2/0
Router(config-if)# network-clock wait-to-restore 10
Hold-Off Time
Use the network-clock hold-off timer global command to configure hold-off time. You can
configure the hold-off time to either 0 or any value between 50 to 10000 ms. The default value is
300 ms. The network-clock hold-off timer can be set in the global configuration mode and the
interface configuration mode. The following example shows how to configure the hold-off timer:
Router(config-if)# network-clock hold-off 50 global
Force Switch
Use the network-clock switch force command to forcefully select a synchronization source
irrespective of whether the source is available, and within range. The following example shows how
to configure a force switch:
Router# network-clock switch force interface gigabitethernet 0/2/0
Manual Switch
Use the network-clock switch manual command to manually select a synchronization source,
provided the clock source has a higher quality level than the currently active clock. The following
example shows how to configure a manual switch:
Router# network-clock switch manual interface gigabitethernet 0/2/0
Clear Manual and Force Switch
Use the network-clock clear switch controller-id command to clear the manual, or switch it on by
force. The following example shows how to clear a switch:
Router# network-clock clear switch t0
Lock Out a Source
Use the network-clock set lockout command to lock out a clock source. A clock source flagged as
lock-out is not selected for SyncE. To clear the lock-out on a source, use the network-clock clear
lockout command. The following example shows how to lock out a clock source:
Router# network-clock set lockout interface gigabitethernet 0/2/0
The following example shows how to clear the lock out on a clock source:
Router# network-clock clear lockout interface gigabitethernet 0/2/0
Use the show network-clock synchronization command to display the output:
Router# show network-clock synchronization
Symbols: En - Enable, Dis - Disable, Adis - Admin Disable
NA - Not Applicable
* - Synchronization source selected
# - Synchronization source force selected
