Ip Networking Overview - Cisco ONS 15600 Reference Manual

Management Network Connectivity
This chapter provides an overview of Cisco ONS 15600 SDH data communications network (DCN)
connectivity. Cisco optical network communication is based on IP, including communication between
Cisco Transport Controller (CTC) computers and ONS 15600 SDHs, and communication among
networked ONS 15600 SDH nodes. The chapter provides scenarios showing ONS 15600 SDHs in
common IP network configurations as well as information about the IP routing table, external firewalls,
and open gateway network element (GNE) networks.
This chapter does not provide a comprehensive explanation of IP networking concepts and procedures,
Note
nor does it provide IP addressing examples to meet all networked scenarios. For ONS 15600 SDH
networking setup instructions, refer to the "Turn Up a Node" chapter of the Cisco ONS 15600 SDH
Procedure Guide.
Although ONS 15600 SDH DCN communication is based on IP, ONS 15600 SDHs can be networked to
equipment that is based on the Open System Interconnection (OSI) protocol suites. This chapter
describes the ONS 15600 SDH OSI implementation and provides scenarios that show how
ONS 15600 SDH can be networked within a mixed IP and OSI environment.

To set up ONS 15600 SDHs within an IP network, you must work with a LAN administrator or other
Note
individual at your site who has IP networking training and experience.
