Issue
Set-up the Link Addressing using the Pocket Terminal (LA +) for port 1 via the DNN3 service port and set port 2 on the DNN3 to be Serial PPP. Can't communicate to the DNN3 from the Sigma server and global data is not being passed between the two VLAN's.
Environment
- Multiple Sigma controllers across at least two Ethernet VLAN's.
- DNN3's (version 1.h) connected to each VLAN.
- Each DNN3 is connected to the VLAN via port 1 and port 2 is configured as a 'virtual' serial PPP port but not connected to a device.
Cause
- No routing information (static routes) entered into the DNN3's. Although Link Addressing can be correctly configured the DNN3 devices also need to know where to transmit the point to point global data, that is the router device for the local Ethernet VLAN or default gateway.
- By having two ports configured on the DNN3 network routing messages RIP will be enabled and broadcast and will advertise the port 2 address as a potential but false route off the network, therefore RIP must also be disabled.
Resolution
-
Using Pocket Terminal or Windows Hyperterminal enter a default Static Route to the DNN3 via its service port. Use the generic entry
0.0.0.0/0 for the destination sub-LAN and mask. For example;
SR+ 0.0.0.0/0 192.168.1.253 1 (Where 192.168.1.253 is the default gateway and 1 is the DNN port number). -
RIP must also be disabled on the DNN3 port 1. For example;
RIPD 1
