Configuring Unit Redundancy for the PTP 820G
This section explains how to configure unit redundancy for the PTP 820G, and includes the following topics:
•
•
•
Cabling Requirements for Unit Redundancy
•
Configuring Ethernet Interface Protection
•
•
Changing the Configuration after Enabling Unit Redundancy
•
Viewing the Configuration of the Standby Unit
•
Viewing Link and Protection Status and Activity
•
•
•
Unit Redundancy Overview
Note
The following protocols cannot be used with unit redundancy:
•
G.8032
•
MSTP
•
LLDP
•
Service OAM (SOAM)
Unit redundancy utilizes two PTP 820G units, with a single antenna, to provide hardware protection for the PTP
820G IDU and RFU, including protection for Ethernet, radio, and TDM interfaces. One PTP 820G operates in active
mode and the other operates in standby mode. If a protection switchover occurs, the roles are switched. The
standby unit is managed by the active unit. The standby unit’s transmitter is muted, but the standby unit’s receiver
is kept on in order to monitor the link. However, the received signal is terminated at the switch level.
There are three modes for Ethernet interface protection with PTP 820G unit redundancy:
•
Line Protection Mode
–
Traffic is routed to the Ethernet interfaces via two interfaces on an external switch.
LACP protocol is used to determine which PTP 820G port is active and which port is standby, and traffic is only
forwarded to the active port. Line Protection mode can be used with optical and electrical Ethernet interfaces.
