Determining the
Configuration
Source
Table 3-1 shows how to determine the carrier configuration source
.
*
Use the SHOW DEVICE command to view the DIP configuration setting. Use the SET DEVICE
DIP_CONFIGURATION command to change the DIP configuration setting.
†
If the carrier does not have configuration settings stored in NVRAM, it uses default settings.
If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use
default settings. For example, if you install the carrier with ports assigned to Ethernet_8 into an
ONcore hub model that does not support Ethernet_8. If the configuration problem is port
level, the DMM forces only the affected ports to use default settings.
‡
The DMM must be fully initialized when you install the carrier module.
Selecting a Network
The Edge Router engine connects to an Ethernet network through a
backplane port on the ONcore carrier. A base engine installed in ONcore
carrier engine bay 1 uses carrier backplane port 1. A base engine installed in
ONcore carrier engine bay 2 uses carrier backplane port 5.
You can assign a carrier backplane port to:
■
One of eight Ethernet backplane networks
■
One of four Isolated backplane networks
For details on backplane networks, refer to the
ONcore Switching Hub
Installation and Operation Guide
(Document Number 17-00362-5).
