Ethernet Circuits
The ONS 15327 has three common methods for configuring Ethernet circuits
between ONS nodes: a straight-circuit configuration, a shared packet ring
configuration, and a hub and spoke configuration. Two nodes usually connect with
a straight circuit configuration. More than two nodes usually connect with a
shared packet ring or a hub and spoke configuration. You can also manually cross
connect individual Ethernet circuits to an STS channel on the ONS 15327 optical
interface.
Network Management
The ONS 15327 is compatible with several network management protocols, such
as Simple Network Management Protocol (SNMP), Proxy Address Resolution
Protocol (ARP), and Open Shortest Path First (OSPF) protocol. If OSPF is not
available, static routes can also connect to ONS 15327s through routers. DCC
tunneling is provided for interoperability with other vendors’ equipment.
