Chapter 17 Configuring Synchronous Ethernet ESMC and SSM
Configuration Examples for Synchronous Ethernet (SyncE): ESMC and SSM
You can use the show network-clocks command to verify your configuration.
Configuration Examples for Synchronous Ethernet (SyncE):
ESMC and SSM
Example: Synchronous Ethernet (SyncE): ESMC and SSM
The following examples show the SyncE configuration sequence (configuring an interface with two
SyncE interfaces and two external interfaces):
Interface GigabitEthernet0/0
synchronous mode
network-clock wait-to-restore 720
!
Interface GigabitEthernet0/1
synchronous mode
!
controller BITS
ssm
!
network-clock synchronization automatic
network-clock input-source 1 controller BITS
network-clock input-source 1 gigabitethernet 0/0
network-clock input-source 2 gigabitethernet 0/1
network-clock synchronization mode QL-enabled
network-clock-select hold-timeout infinite
network-clock-select mode nonrevert
The following examples shows how to verify whether ESMC is enabled or not:
Router# show esmc
Interface: GigabitEthernet0/0
Administrative configurations:
Mode: Synchronous
ESMC TX: Enable
ESMC RX : Enable
QL RX configured : NA
QL TX configured : NA
Operational status:
Port status: UP
Step 26
network-clock wait-to-restore seconds
Example:
Router(config-if)# network-clock
wait-to-restore 70
(Optional) Configures wait-to-restore timer for the SyncE
interface.
Step 27
end
Example:
Router(config-if)# end
Exits interface configuration mode and returns to privileged
EXEC mode.
