Chapter 8 Management Network Connectivity
IP Addressing Scenarios
In the example, the GNE is assigned an IP address within the central office LAN and is physically
connected to the LAN through its LAN port. ENEs are assigned IP addresses that are outside the central
office LAN and given private network IP addresses. If the ENEs are collocated, the LAN ports could be
connected to a hub. However, the hub should have no other network connections.
Figure 8-10 ONS 15310-MA SDH Proxy Server with GNE and ENEs on the Same Subnet
Table 8-2 shows recommended settings for ONS 15310-MA SDH GNEs and ENEs in the configuration
shown in Figure 8-10.
Figure 8-11 shows the same proxy server implementation with ONS 15310-MA SDH ENEs on different
subnets. In this example, GNEs and ENEs are provisioned with the settings shown in Table 8-2.
