This section describes the fields in the Bridging and Routing configuration window.
Inverse Mux (Multiplex) Configuration —
This function lets you balance your LAN traffic
between two T1 WAN ports and is used with Point to Point Protocol (PPP) or HDLC protocol.
QuickSET automatically sets the WAN Frame Type to Encapsulated Ethernet when you use the
Inverse Mux configuration. When you select the Inverse Mux check box, bridging, IP routing, and
IPX routing functions are all disabled. The WAN device at the other end of the WAN link(s) must
be a Cabletron Systems device capable of receiving the balanced WAN traffic.
MAC Bridging —
This field allows you to specify whether or not the HSIM-W6 bridges traffic.
Click on the check box to turn on MAC Bridging.
Spanning Tree Protocol —
This field is grayed out until MAC Bridging is turned on. It allows
you to configure the HSIM-W6 to use the Spanning Tree Protocol, which lets the remote device
check for bridging loops, and check for other sites that use the Spanning Tree Protocol. Click on
the radio button to turn on Spanning Tree Protocol.
IP Routing —
The IP Routing check box allows you to turn on/off IP Routing. Click on the check
box to turn on IP Routing.
IPX Routing —
The IPX Routing check box allows you to turn on/off IPX Routing. Click on the
check box to turn on IPX Routing.
External HSIM Network # —
This field displays the IPX network number assigned to the
external Ethernet IPX network on the HSIM-W6. It is grayed out until IPX Routing is turned on.
Frame Type —
This field is grayed out until IPX Routing is turned on. It allows you to select the
type of IPX frame in which packets are encapsulated for transmission. Select one of the four
available frame types.
The Firewall Configuration Window
The Firewall configuration window shown in
displays after clicking on the Firewall...
button in the Bridging and Routing configuration window. The Firewall configuration window is
used to configure an Access Control List (ACL), and to allow or deny specified IP addresses to
communicate through the HSIM-W6.
NOTE
The Inverse Mux function is enabled or disabled only through QuickSET, not Local
Management. Statistics regarding the Inverse Mux configuration are accessed via the
imux MIB Navigator command. See
for more information.
