Chapter 11 Network Synchronization Support
Configuring Network Synchronization
Managing Synchronization
Manage synchronization on a Cisco ASR 1000 Series Aggregation Service Router using the following
management commands:
• network-clock synchronization mode QL-enabled command
Use the network-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 command
Use the esmc process command in the global configuration mode to enable the ESMC process at
system level. The no form of this command disables the ESMC process. The no form of this
command fails if no SyncE-capable interface is installed on the platform.
The following example shows how to enable the ESMC process in the global configuration mode:
Router(config)# esmc process
• esmc mode [tx | rx] command
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 quality-level command
Use the network-clock source quality-level command in the interface configuration mode to
configure the QL value for ESMC on a gigabit Ethernet 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 network-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 command in the global
configuration mode:
Router(config)# network-clock quality-level rx qL-pRC external R0 2048k
