IP addressing for SMB devices and DHCP 19

All reference topologies assume that each device on the subnet has its

SNMP client enabled.

IP addressing for SMB devices and DHCP

Nortel recommends using DHCP to obtain IP addresses for SMB devices

and end nodes (such as PCs and IP phones).

The SMB reference topologies 2 and 3 rely on a DHCP server running on

the BSR222 in the subnet (typically occupying address 192.168.1.1). SMB

reference topology 1 relies on a DHCP serverrunning on a third-party router.

DHCP serves IP addresses dynamically to all devices and end nodes

connected to the subnet. As devices are connected to the subnet, they

take IP addresses from the DHCP pool from 192.168.1.2 to 192.168.1.127

inclusive.

If DHCP is not r unning on the subnet, all SMB devices are shipped with

factory-default IP addresses that exist within ranges of the subnet that

minimize IP address conﬂict.

The following table lists the default IP addresses, valid IP ranges, and

default DHCP status for all SMB devices.
