Configuring Clock Recovery from SyncE
This section describes how to configure clock recovery by using the SyncE method.
SUMMARY STEPS
1. configure terminal
2. network-clock synchronization automatic
3. network-clock synchronization ssm option {1 | 2 {GEN1 | GEN2}}
4. interface gigabitethernet slot/card/port
5. synchronous mode
6. exit
7. network-clock input-source priority {interface interface-name slot/card/port | {external
slot/card/port}}
8. exit
DETAILED STEPS
Examples
The following example shows how to configure clock recovery from SyncE:
Router# configure terminal
Router(config)# network-clock sync
hronization automatic
Router(config)# network-clock sync
hronization ssm option 2 GEN1
Router(config)# interface gigabite
thernet 0/2/0
Router(config-if)# synchronous mod
e
Router(config)# exit
Router(config)# network-clock inpu
t-source 1 interface gigabitethernet 0/2/0
Router(config)# exit
