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 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 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.
