Selecting an IP Addressing Scheme
You can select from many IP addressing schemes to provide SNMP NMS
connectivity. Review the following information in preparation for selecting an
IP addressing scheme.
H Assign IP addresses to:
— The Management port
— The IMC
Refer to the
IP
Addressing Scheme Examples
section.
H When the Routing Information Protocol (RIP) option is set to Proprietary,
IP routing information is automatically passed between interconnected DSUs
from the network side. Refer to Management Port Options, Table A-5.
However, verify that a route to the subnet(s) is set in the NMS’s or local
router’s routing table. This equipment will not automatically receive routing
information due to the proprietary protocol.
The gateway to subnet(s) is through the DSU connected to:
— The LAN using a LAN adapter, or
— A router, terminal server, or NMS via PPP or SLIP link-layer protocols
H Each DSU’s routing table supports a maximum of 20 routes, even though a
single route is all that is needed to reach every device on a subnet.
H Set a default route only for devices directly connected to the DSU’s
Management port.
H Any legal host address is allowed for a given subnet; the address choice
within the subnet is completely arbitrary.
