Managing Synchronization on the Cisco ASR 1000 Series Router
Manage synchronization on a Cisco ASR 1000 Series Router using the following management
commands:
• Quality-Level-Enabled Clock Selection
Use the netw
ork-clock synchronization mode QL-enabled command in the global configuration
mode to configure the automatic selection process for the QL-enabled mode. This succeeds only if
the SyncE interfaces are capable of sending SSMs. The following example shows how to configure
network clock synchronization (QL-enabled mode) in the global configuration mode:
Router(config)# network-clock synchronization mode QL-enabled
• ESMC Process
Use the es
mc process command in the global configuration mode to enable the ESMC process at
system level. The no form of the command disables the ESMC process. The no form of the
command fails if there is no SyncE-capable interface is installed in the platform. The following
example shows how to enable ESMC in the global configuration mode:
Router(config)# esmc process
• ESMC Mode
Use the esmc mode [tx | rx] command
in the interface configuration mode to enable the ESMC
process at the interface level. The no form of the command disables the ESMC process. The
following example shows how to enable ESMC in the interface configuration mode:
Router(config-if)# esmc mode tx
• Network Clock Source Quality Level
Use the n
etwork-clock quality-level command in the interface configuration mode to configure
the QL value for ESMC on a gigabitethernet port. The value is based on global interworking options:
– If Option 1 is configured, the available values are QL-PRC, QL-SSU-A, QL-SSU-B, QL-SEC,
and QL-DNU.
– If Option 2 is configured with GEN 2, the available values are QL-PRS, QL-STU, QL-ST2,
QL-TNC, QL-ST3, QL-SMC, QL-ST4, and QL-DUS.
– If Option 2 is configured with GEN1, the available values are QL-PRS, QL-STU, QL-ST2,
QL-SMC, QL-ST4, and QL-DUS
The following example shows how to configure the netw
ork-clock source quality-level in the
interface configuration mode:
Router(config-if)# network-clock source quality-level QL-PRC rx
Use the network-clock quality-level command in the global configuration mode to configure the
QL value for the SSMs on a BITS port. The following example shows how to configure
network-clock quality-level in the global configuration mode:
Router(config)# network-clock quality-level rx qL-pRC external R0 2048k
• Wait-to-Restore Timer
Use the netw
ork-clock wait-to-restore timer global command to set the wait-to-restore time. You
can configure the wait-to-restore time to any value between 0 to 86400 seconds. The default value
is 300 seconds. The wait-to-restore timer can be set in the global configuration mode and the
interface configuration mode. The following example shows how to configure the wait-to-restore
timer in the global configuration mode:
