Configuring the Network Clock in Interface Configuration Mode

Use the following commands in the interface configuration mode to configure the network clock and timers
on the Cisco ASR 1000 Series Routers SIP-40.
Command
Router(config-if)# synchronous mode
Example:
Router(config-if)# synchronous mode
Router(config-if)# esmc mode [tx | rx |<cr>]
Example:
Router(config-if)#
Router(config-if)# network-clock source
quality-level <value> {tx | rx}
Example:
Router(config-if)#
quality-level
Router(config-if)# network-clock hold-off <0 |
50-10000>
Example:
Router(config-if)#
OL-14127-17

Purpose
Configures the ethernet interface to synchronous
mode and this automatically enables the ESMC and
Quality Level process on the interface.
Note This command is applicable to Synchronous
Ethernet capable interfaces. The default
value is asynchronous mode.
Enables or disables ESMC process on the interface.
If the interface is configured as line source
Note
but does not receive ESMC message from
peer node on the interface, then the interface
is removed from selectable clock source list.
By default this is enabled for synchronous
mode and disabled for asynchronous mode.
Note This command is not supported for
non-synchronous ethernet interfaces.
The command forces QL value to local clock selection
process and it is considered by the clock selection
process as a value from network. The value is based
on global interworking Option.
• If Option 1 is configured, the available values
are QL-PRC, QL-SSU-A, QL-SSU-B, QL-SEC,
and QL-DNU.
• If Option 2 is configured with GEN 2, the
available values are QL-PRS, QL-STU,
QL-ST2, QL-TNC, QL-ST3, QL-SMC, QL-ST4
and QL-DUS.
• If option 2 is configured with GEN1, the
available values are QL-PRS, QL-STU,
QL-ST2, QL-SMC, QL-ST4 and QL-DUS
This command is applicable to Synchronous
Note
Ethernet capable interfaces.
Configures hold-off timer for interface. The default
value is 300 milliseconds.
Note Displays a warning for values below 300 ms
and above 1800 ms.
