IP Addressing 5

Selecting an IP Addressing Scheme

You can select from many IP (Internet Protocol) addressing schemes to provide
SNMP NMS connectivity. Review the following information in preparation for
selecting an IP addressing scheme.
You can assign IP addresses to the:
— 10BaseT port
— IMC
When the IMC Routing Information Protocol option is set to Proprietary,
IP routing information is automatically passed between interconnected DSUs
from the network side.
A static route to the DSU that is managed over the IMC must be set in the
routing table of the NMS host or local router.
Each DSU’s internal 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.
Any legal host address is allowed for a given subnet; the address choice
within the subnet is completely arbitrary.
The 48-bit MAC (Media Access Control) address of the 10BaseT port does
not govern the port’s 32-bit IP address.
