Configuring Clock Recovery from a BITS Port
This section describes how to configure clock recovery from BITS port.
SUMMARY STEPS
1. enable
2. configure terminal
3. network-clock synchronization automatic
4. network-clock synchronization ssm option option_Id Generation_Id
5. network-clock input-source priority {interface interface_name slot/card/port | {external
slot/card/port }}
6. exit
DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router# enable
Enables the privileged EXEC mode.
Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3
network-clock synchronization automatic
Example:
Router(config)# network-clock
synchronization automatic
Enables the network clock selection algorithm. This
command disables the Cisco-specific network clock
process, and turns on the G.781-based automatic clock
selection process.
Step 4
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 synchronization
network. The option_id value 1 refers to synchronization
networks design for Europe. This is the default value. The
option_id value 2 refers to the synchronization networks
design for the U.S.
