Configuring Network Synchronization Network Synchronization Support Router(config)# network-clock wait-to-restore 10 global The following example shows how to configure the wait-to-restore timer in the interface configuration mode: Router(config)# interface gigabitethernet 0/2/0 Router(config-if)# network-clock wait-to-restore 10 • Hold-Off Time Use the network-clock hold-off timer global command to configure hold-off time. You can configure the hold-off time to either 0 or any value between 50 to 10000 ms. The default value is 300 ms. The network-clock hold-off timer can be set in the global configuration mode and the interface configuration mode. The following example shows how to configure the hold-off timer: Router(config-if)# network-clock hold-off 50 global • Force Switch Use the network-clock switch force command to forcefully select a synchronization source irrespective of whether the source is available, and within range. The following example shows how to configure a force switch: Router# network-clock switch force interface gigabitethernet 0/2/0 • Manual Switch Use the network-clock switch manual command to manually select a synchronization source, provided the clock source has a higher quality level than the currently active clock. The following example shows how to configure a manual switch: Router# network-clock switch manual interface gigabitethernet 0/2/0 • Clear Manual and Force Switch Use the network-clock clear switch controller-id command to clear the manual, or switch it on by force. The following example shows how to clear a switch: Router# network-clock clear switch t0 • Lock Out a Source Use the network-clock set lockout command to lock out a clock source. A clock source flagged as lock-out is not selected for SyncE. To clear the lock-out on a source, use the network-clock clear lockout command. The following example shows how to lock out a clock source: Router# network-clock set lockout interface gigabitethernet 0/2/0 The following example shows how to clear the lock out on a clock source: Router# network-clock clear lockout interface gigabitethernet 0/2/0 Verifying the Network Synchronization Configuration Use the following commands to verify the network synchronization configuration: • Use the show network-clock synchronization command to display the output: Router# show network-clock synchronization Symbols: En - Enable, Dis - Disable, Adis - Admin Disable NA - Not Applicable * - Synchronization source selected # - Synchronization source force selected Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide 12
