Chapter 10 Synchronous Ethernet Support Configuring Synchronous Ethernet Configuring Clock Recovery from SyncE This section describes how to configure clock recovery on Cisco ASR 1000 Series Router from SyncE method. SUMMARY STEPS 1. enable 2. configure terminal 3. network-clock synchronization automatic 4. network-clock synchronization ssm option option_Id Generation_Id 5. interface gigabitethernet slot/port 6. synchronous mode 7. exit 8. network-clock input-source priority {interface interface_name slot/card/port | {external slot/card/port }} 9. exit DETAILED STEPS Step 1 Command enable Step 2 Example: Router# enable configure terminal Purpose Enables the privileged EXEC mode. Enter your password if prompted. Enters the global configuration mode. Step 3 Step 4 Example: Router# configure terminal network-clock synchronization automatic Enables the network clock selection algorithm. This command disables the Cisco-specific network-clock Example: Router(config)# network-clock process, and turns on G.781-based automatic clock selection process. synchronization automatic network-clock synchronization ssm option {option_id {GEN1 | GEN2}} Example: Router(config)# network-clock synchronization ssm option 2 GEN1 Configures the equipment to work in a synchronization network. The option_id value 1 refers to a synchronization networks design for Europe. This is the default value. The option_id value 2 refers to a synchronization networks design for the U.S. OL-16506-10 Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide 10-5
