15.3.3 Management of Non-LAN Connected Multishelf Node
When using dense wavelength division multiplexing (DWDM) multishelf management feature to
subtend shelves from a node controller shelf, the Node Controller must be specially provisioned in case
it does not have direct LAN reachability.
Non-LAN connected Multishelf nodes are not manageable from CTC unless SOCKS Proxy is enabled
on the node. In a GNE/ENE firewall configuration, non-LAN connected network elements must be set
up as end network elements (ENEs) if Firewall is required. If firewall is not required on the non-LAN
connected Multishelf node, then the node must be set up as SOCKS Proxy
LAN-connected network elements (LNEs) can be set up as gateway network elements (GNEs) or as
SOCKS proxies, depending upon network security requirements. If the GNE/ENE firewall feature is
required, the LNE must be set up as a GNE. If the design does not require the firewall feature but does
require all-IP networking, the LNE must be set up as a SOCKS proxy. For procedures to provision a node
or shelf as a GNE, ENE or SOCKS proxy, refer to the Cisco ONS 15454 DWDM Procedure Guide.
15.3.4 DCN Case Study 1: Ring Topology with Two Subnets and Two DCN
Connections
DCN Case Study 1 (Figure 15-17) shows an ONS 15454 ring (DWDM or SONET/SDH). The ring is
divided into two subnets and has two DCN connections for resiliency.
