2. Set the SyncE mode to QL-disabled.
SwitchA(config)# sync-e mode ql-disabled
3. Enable SyncE on the interfaces that are connected to the clock sources and interfaces transmitting to the neighboring
SyncE node.
SwitchA(config)# interface ethernet 1/1/1
SwitchA(conf-if-eth1/1/1)# sync-e enable
SwitchA(conf-if-eth1/1/1)# exit
SwitchA(config)# interface ethernet 1/1/2
SwitchA(conf-if-eth1/1/2)# sync-e enable
SwitchA(conf-if-eth1/1/2)# exit
SwitchA(config)# interface ethernet 1/1/3
SwitchA(conf-if-eth1/1/3)# sync-e enable
4. Configure priority on the ports to ensure that the best synchronization clock source is selected.
SwitchA(conf-if-eth1/1/2)# sync-e priority 1
5. Verify the SyncE configuration.
