4.2.4.2.3 Ethernet Bridge Mode Configuration via Optional Network
Processor (NP) Interface
Ethernet Bridge Mode redundancy, when using SLM ‐ 5650/5650A modems equipped with the
optional Network Processor (NP) Interface, is provided by a single IP address scheme.
Follow these steps to verify Single IP Address Mode on the Online Modem:
Step Task
1
From the SLM-5650A front panel, navigate to Config: Remote Æ EthernetConfig Æ
Option Card Addr Æ Network Proc.
2 Verify that the Mode appears as Single.
Follow these steps to verify Single IP Address Mode on the Offline Modem:
Step Task

Network Proc.
2 Set the Traffic IP Address of the Online Modem only.
3 Verify that the Traffic IP Address also appears on the Offline Modem.
In Ethernet Bridge Mode, the CRS ‐ 311 will keep the Online Modem’s Ethernet Ports 2 ‐ 4 turned
on . The CRS ‐ 311 will keep the Offline Modem’s Ethernet Ports 2 ‐ 4 turned off . The traffic IP
address is only accessible on the Online Modem; there is NO access to the Offline Modem.
Furthermore, in Ethernet Bridge Mode, the parameter backup mechanism is unsupported;
therefore, you must make sure that all parameters match in the Online and Offline modems.
See the SLM ‐ 5650 or the SLM ‐ 5650A Installation and Operation Manual for detailed
configuration information.
4.2.4.2.4 Ethernet Bridge Mode Configuration via Optional GbE Interface
Ethernet Bridge Mode redundancy, when using SLM ‐ 5650/5650 modems equipped with the
optional 10/100/1000 Base ‐ T (GbE) Interface, is provided by a Single IP Address scheme.
To configure the SLM ‐ 5650/5650A for Ethernet Bridge Mode 1:1 redundancy, for each modem
enter a unique IP Address for the optional 10/100/1000 Base ‐ T (GbE) Interface Module that is
on the same subnet:
