Chapter 11 Network Synchronization Support
Configuring Network Synchronization
Examples
The following example shows how to configure clock recovery from SyncE:
Router# configure terminal
Router(config)# network-clock synchronization automatic
Router(config)# network-clock synchronization ssm option 2 GEN1
Router(config)# interface gigabitethernet 0/2/0
Router(config-if)# synchronous mode
Router(config)# exit
Router(config)# network-clock input-source 1 interface gigabitethernet 0/2/0
Router(config)# exit
Configuring Clock Recovery from a BITS Port
This section describes how to configure clock recovery from a BITS port. BITS port can be configured
either as an input-source or an output-source.
• Configuring Clock Recovery with a BITS Port as an Input-Source, page 11-10
• Configuring Clock Recovery with a BITS Port as an Output-Source, page 11-11
Step 4
interface gigabitethernet
slot/card/port
Example:
Router(config)# interface
gigabitethernet 0/2/0
Specifies the Gigabit Ethernet interface to be
configured:
slot/card/port—Specifies the location of the interface.
Step 5
synchronous mode
Example:
Router(config-if)# synchronous mode
Sets the mode to synchronous mode.
Step 6
exit
Example:
Router(config)# exit
Exits the global configuration mode.
Step 7
network-clock input-source priority
{interface interface-name
slot/card/port | {external
slot/card/port}}
Router(config)# network-clock
input-source 1 interface
gigabitethernet 0/2/0
Router(config)# network-clock
input-source 1 external R0 2048k
Enables clock recovery from SyncE.
The Cisco ASR1006 router supports two RP ports, one
active and the other standby.
Step 8
exit
Example:
Router(config)# exit
Exits the global configuration mode.
