Cisco Content Hub Synchronous Ethernet Esmc And Ssm

Synchronous Ethernet (SyncE) ESMC and SSM This module describes Synchronization Status Message (SSM), Ethernet Synchronization Message Channel (ESMC), and generating the Simple Network Management Protocol (SNMP) traps on the SyncE feature.

To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required. Prerequisites for Synchronous Ethernet (SyncE) ESMC and SSM. You need to first configure the network clock for SyncE configuration. Automatic synchronization of the network clock should be enabled.

Configuring Synchronous Ethernet ESMC and SSM. Contents. Synchronous Ethernet is an extension of Ethernet designed to provide the reliability found in traditional SONET/SDH and T1/E1 networks to Ethernet packet networks by incorporating clock synchronization features. Clock Selection Modes. Managing Clock Selection.

You need to first configure the network clock for SyncE configuration. Automatic synchronization of the network clock should be enabled.

In SONET/SDH the communication channel for conveying clock information is Synchronization Status Message (SSM), and in SyncE it is the Ethernet Synchronization Message Channel (ESMC). Note For information about how to configure synchronous Ethernet, see "Configuring Clocking and Timing" .

While SONET and SDH transmit the SSM in a fixed location within the frame, Ethernet Synchronization Message Channel (ESMC) transmits the SSM using a protocol: the IEEE 802.3 Organization-Specific Slow Protocol (OSSP) standard.

With Enhanced SyncE (eSyncE) and Extended Ethernet Synchronization Message Channel (eESMC) support, the NCS 5500 and NCS 5700 Series Routers are capable of handling the following SyncE clocks on the network:

Understanding Synchronous Ethernet ESMC and SSM. Ethernet Synchronization Message Channel (ESMC) incorporates the Synchronization Status Message (SSM) used in Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) networks.

Understanding Synchronous Ethernet ESMC and SSM. Synchronous Ethernet incorporates the Synchronization Status Message (SSM) used in Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) networks.

Synchronous Ethernet Support. Most of the services that are provided over networks must be fully synchronized with one another in order to operate efficiently. If the network devices that constitute a network do not operate at the same clock rates, there is an overall decrease in the performance of the network and a consequent degradation in ...

Verifying the Configuration. Troubleshooting. Configuration Examples. SSM Support on Cisco ASR 900 Series 4-Port OC3/STM1 or 1-Port OC12/STM4 Interface Module.

Aug 1, 2010 Operation messages maintain SyncE links and ensure that a node always derives timing from the most reliable source. SyncE synchronizes clock frequency over an Ethernet port. In SONET/SDH the communication channel for conveying clock information is SSM, and in SyncE it is the ESMC.
