3. Determine ZyWAN Network Address (DHCP)
Port 1 on the ZyWAN is typically set to acquire its address automatically using DHCP. Since the address is
dynamically assigned, the ZyWAN address must be determined before it can be configured.
One way to check the ZyWAN network address is to use a crossover (null modem) serial cable between the
PC and the ZyWAN. The null modem cable can be purchased from Eurotech, or it may be obtained from an
electronics supply store.
Tip:
If your network administrator can determine the DHCP assigned address after the
ZyWAN starts up, the serial cable is not needed. Skip to Browse ZyWAN
Configuration Page on page 35 .
To determine the ZyWAN network address (DHCP), complete the following steps:
1. Use Windows HyperTerminal to establish communication to the ZyWAN on COM1 at 115,200 baud.
See Windows HyperTerminal on page 25 , for help with this step.
2. If the ZyWAN is already started, press the Enter key to get a login prompt. The default login is
root
and the default password is
arcom
(case-sensitive).
3. After logging into the ZyWAN, type the command
ifconfig eth1
at the command prompt. The
current network address which has been assigned to the ZyWAN by the network is displayed.
Note:
If the
ifconfig
command does not show an
inet addr
address, it may be that the
network does not have a DHCP server or that security policies prohibit the ZyWAN
from obtaining its address. An address can be manually set if necessary by issuing the
following command:
ifconfig eth1 ip_address netmask subnet
where
ip_address
is the actual address on the network, and
subnet
is the subnet
mask in dotted notation (such as 255.255.0.0).
