EWR/PWR Users Guide
reserved for a specific device. The
reserved
checkbox must be marked for this kind of IP
address reservation. The
Status
field indicates whether the provisioned IP address was
detected (via a ping) when the web page was brought up.
The IP addresses default to values based on the transceiver MAC address of the device. The
derivation is described below. By default, only the first IP address is enabled (for
local-DHCP
),
and no addresses are reserved for specific MAC addresses.
Please make sure to check the checkbox for the client IP addresses you have entered. Client 2
and Client 3 are not enabled by default. In this example, the EWR wired interface is assigned
the IP address 172.16.2.1. This address is hidden from the core network and the IAP will not
route for this address. The core network must use the 172.16.1.37 address to access the EWR
(which is the address obtained via MeshManager).
The EWR/PWR has two interfaces and must use two IP addresses. The wireless network must
use the IP address on the wireless interface because that is the address for which the IAP will
proxy and advertise. The same address will be accessed by the Device Manager when using
MeshManager.
The
wired interface address
will be used by the EWR/PWR as the gateway address for the local
Ethernet segment. The
wired subnet mask
is configurable so that the user may select a more
restrictive subnet on the local Ethernet segment than what is normally provided to the wireless
subscribers.
The MAC-derived default values are a means to ensure that these devices are likely to work
out-of-the-box. The IP addresses are derived as follows:
Transceiver MAC address: 00:05:12:0A:XX:YY
Derived MAC addresses:
Local gateway:
10.xx.yy.9
Client1: 10.xx.yy.10
Client2: 10.xx.yy.11
Client3: 10.xx.yy.12
Where XX and YY are hex values (from the transceiver MAC address), and the lowercase xx
and yy are the same values in decimal. For example, a EWR with transceiver MAC address of
00:05:12:0A:80:20 would have a default local gateway address of 10.128.32.9.
The user is encouraged to change these addresses upon installation.
3.4.1 Connecting to the Ethernet Port
If only one device is to be connected to the EWR/PWR, you can connect directly to the device
using an Ethernet cable.
If you are going to connect more than one device to the EWR, you will need to connect a hub to
the EWR/PWR, and connect the other devices to the hub.
