Configuring the Ethernet SPAs
with devices that do not support synchronization, synchronization features can be disabled or partially enabled
to maintain backward compatibility.
For additional details to understand how SyncE feature is implemented on Cisco ASR 1000 Series
Note
Aggregation Services Routers using 4 different configuration, see the chapter 'Synchronous Ethernet
Support On Cisco ASR 1000 Series Aggregation Services Routers' in the
Configuration Guide .
The network clock can be configured in global configuration mode and interface configuration mode:
Configuring the Network Clock in Global Configuration Mode
Use the following commands to configure the network clock in global configuration mode on the Cisco SIP-40:
Command
Router(config)# [no] network-clock
synchronization automatic
Example:
Router(config)# network-clock synchronization
automatic
Router(config)# [no] network-clock eec {1 | 2}
Example:
Router(config)# network-clock eec 1
Router(config)# [no] network-clock
synchronization ssm option {1| 2 {GEN1 | GEN2}}
Example:
Router(config)# network-clock synchronization
ssm option 2 GEN1

Purpose
Enables G.781 based automatic clock selection
process. G.781 is the ITU-T Recommendation that
specifies the synchronization layer functions.
Configures the clocking system hardware with the
desired parameters. These are the options:
• For option 1, the default value is EEC-Option
1 (2048).
• For option 2, the default value is EEC-Option
2 (1544).
Configures the router to work in a synchronized
network mode, as described in G.781. The following
are the options:
• Option 1: Refers to synchronization networks
designed for Europe (SDH/ E1 framings are
compatible with this option).
• Option 2: Refers to synchronization networks
designed for the US (SONET/T1 framings are
compatible with this option).
The default option is 1. While choosing option 2, you
must specify whether it is second-generation message
(GEN2) or first-generation message (GEN1).
Network clock configurations that are not
Note
common between options should be
configured again.
