Ethernet Bridge
Response
Description
Bridges let you join two local area networks, so that they appear to be
part of the same physical network. As a bridge for protocols other than
TCP/IP, your Gateway keeps track of as many as 255 MAC (Media
Access Control) addresses, each of which uniquely identifies an individ-
ual host on a network. Your Gateway uses this bridging table to identify
which hosts are accessible through which of its network interfaces. The
bridging table contains the MAC address of each packet it sees, along
with the interface over which it received the packet. Over time, the
Gateway learns which hosts are available through its WAN port, its LAN
port, and/or its wireless interface.

System
Response
Description
The
System Name
defaults to your Gateway's factory identifier com-
bined with its serial number. Some cable-oriented Service Providers use
the System Name as an important identification and support parame-
ter. If your Gateway is part of this type of network, do NOT alter the
System Name unless specifically instructed by your Service Provider.
The System Name can be 1-63 characters long; it can include embed-
ded spaces and special characters.
The
Log Message Level
alters the severity at which messages are col-
lected in the Gateway's system log. Do not alter this field unless
instructed by your Support representative.

Internal Servers
Response
Description
Your Gateway ships with an embedded Web server and support for a
Telnet session, to allow ease of use for configuration and maintenance.
The default ports of
80
for HTTP and
23
for Telnet may be reassigned.
This is necessary if a pinhole is created to support applications using
port 80 or 23. See
“Pinholes” on page 46
for more information on Pin-
hole configuration.
Web (HTTP) Server Port:
To reassign the port number used to access
the Cayman embedded Web server, change this value to a value greater
than 1024. When you next access the embedded Cayman Web server,
append the IP address with <port number>, (e.g. Point your browser to
)
Telnet Server Port:
To reassign the port number used to access your
Cayman embedded Telnet server, change this value to a value greater
than 1024. When you next access the Cayman embedded Telnet server,
append the IP address with <port number>, (e.g.
telnet
210.219.41.20:2323

c Shaping
Response
Description
You can override your Gateway’s Ethernet MAC address with any neces-
sary setting. Some ISPs require your account to be identified by the
MAC address, among other things. For information on setting this
parameter , see
“How to Use the Quickstart Page” on page 36
.
Response
Description
Traffic shaping controls how much traffic can flow through an Ethernet
interface by limiting the size of the Ethernet pipe. This function is most
suitable for Internet Service Providers.
Enable Traffic Shaping on Port
: Each Ethernet port providing traffic
shaping capability is listed. Enable the port to set the traffic shaping
rate.
Rate
: This value, in bits per second, indicates the approximate speed at
which traffic will flow.
