Configuring the Network Clock for the 2-Port Gigabit Synchronous Ethernet SPA on a Cisco ASR 1000 Series Router
Command
Router(config-if)# [no] network-clock
wait-to-restore <0-86400>
Example:
Router(config-if)#
wait-to-restore
Router(config-if)# [no] esmc mode ql-disabled
Example:
Router(config-if)#
Managing Synchronization
You can manage the synchronization using the following management commands:
Command
Router# network-clock set lockout {interface
interface_name slot/card/port | external slot/card/port}
Example:
Router# network-clock set lockout interface
GigabitEthernet 0/0/0
Router# network-clock clear lockout interface
GigabitEthernet 0/0/0
Router# network-clock switch force {interface
interface_name slot/card/port | external slot/card/port
| internal T0}
Example:
Router# network-clock switch force interface
GigabitEthernet 0/0/0 external 0/2/0
Router# network-clock switch manual {interface
interface_name slot/card/port | external slot/card/port
| internal T0}
Example:
Router# network-clock switch manual interface
GigabitEthernet 0/0/0

Configuring the Ethernet SPAs
Purpose
Configures the wait-to-restore timer on the SyncE
interface.
Ensure that you set the wait-to-restore
Caution
values above 50 seconds to avoid timing
flap.
Disables the quality level mode. The default mode
for synchronous ethernet is ql-enabled.
Note
This command is not supported for
non-synchronous ethernet interfaces.
Purpose
Locks 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 network-clock
clear lockout {interface interface_name slot/card/port
| external slot/card/port} command.
Note
Lockout takes precedence over force switch
and force switch overrides the manual
switch.
Forcefully selects a synchronization source
irrespective of whether the source is available and is
within the range.
Manually selects a synchronization source, provided
the source is available and is within the range.
