Chapter 17 Configuring Synchronous Ethernet ESMC and SSM
How to Configure Synchronous Ethernet (SyncE): ESMC and SSM
Step 8
exit
Example:
Router(config-controller)# exit
Router(config)#
Exits controller configuration mode and returns to
configuration mode.
Step 9
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 10
network-clock eec {1 | 2}
Example:
Router(config)# network-clock eec 1
Configures the clocking system hardware with the desired
parameters. These are the options:
• For option 1, the default value is EEC-Option 1 (2048).
• For option 2, the default value is EEC-Option 2 (1544).
Step 11
network-clock synchronization ssm option
{1 | 2 {GEN1 | GEN2}}
Example:
Router(config)# network-clock synchronization
ssm option 2 GEN2
Configures the router to work in a synchronization network.
• Option 1 refers to synchronization networks designed
for Europe. This is the default value.
• Option 2 refers to synchronization networks designed
for United States.
Step 12
network-clock input-source priority {controller
BITS | E1} | {interface type slot/card/port]
{external [2m | 10m]}}
Example:
Router(config)# network-clock input-source 1
interface GigabitEthernet 0/1
Enables you to select an interface as an input clock for the
router. You can select the BITS, Gigabit Ethernet 0/0,
Gigabit Ethernet 0/1 interfaces, or GPS interfaces.
Step 13
network-clock synchronization mode ql-enabled
Example:
Router(config)# network-clock synchronization
mode ql-enabled
Configure the automatic selection process ql-enabled mode.
• QL is disabled by default.
• ql-enabled mode can be used only when the
synchronization interface is capable to send SSM.
Step 14
network-clock hold-off {0 | milliseconds}
Example:
Router(config)# network-clock hold-off 0
(Optional) Configures hold-off timer for the interface.
Step 15
network-clock wait-to-restore seconds
Example:
Router(config)# network-clock wait-to-restore
70
(Optional) Configures wait-to-restore timer for the SyncE
interface.
Step 16
network-clock-select mode {revert | nonrevert}
Example:
Router(config)# network-clock-select mode
revert
(Optional) Specifies the router switching mode when
recovering from a failure.
