42 Avidia System Configuration and Management User Manual
The following figure shows an example campus server configuration.
Determining IP Addressing and Subnet Masks
When you set up enterprise or campus server applications, use this general criteria for assigning
IP addresses.
• The WAN IP address for the modem should be on the same subnet as the Avidia channel
card port to which the modem attaches.
• When a LAN is set up on a modem (CPE), the LAN IP addresses should be on the same
subnet as the LAN port of the modem.
• When a LAN or NMS/EMS is set up on the Ethernet port of the AMC, the IP address for
the LAN or NMS/EMS should be on the same subnet as the AMC Ethernet port.
When you set up a remote system for inband management, you must specify the destination IP
address and subnet mask as well as the gateways and hops to reach the destination. Use the
figure on page 43 as an example of how to set up this connection. This example shows a small
business application using a Remote Access Server (RAS). Applications for a larger business
may use other devices in the network.
