Managing Frame Relay
The 
WAN
 Switching Module (
WSX
) family supports Frame Relay on universal serial, T1 or E1 
ports. Management, data handling, compression, and multi-protocol encapsulation are 
compatible with current Frame Relay standards, such as 
RFC 1490
 and 
FRF.9
. The 
WSX
 
supports all three major 
DLCMI
 management protocols.
WSX
 frame relay extends the power and flexibility of 
LAN
 switching over large geographic 
distances using a Frame Relay network or a leased line, such as a 
T1
. In a Frame Relay 
network configuration, the 
WSX
 provides a cost effective link supporting multiple virtual 
circuits. In a leased line configuration, the 
WSX
 provides dedicated bandwidth to a single 
remote site.
VLAN
 architectures are preserved and consistent on both sides of a 
WAN
 link. The 
WSX
 
supports frame relay trunking, so 
VLAN
 Groups on one side of a Frame Relay link are compat-
ible with those on the other side. In addition, the 
WSX
 is capable of Frame Relay IP and IPX 
routing and complies with Inverse Address Resolution Protocol (In
ARP
RFC 1293
.
In a typical configuration, the 
WSX
 occupies one slot in an Omni Switch/Router. Since it is 
compatible with Omni Switch/Router any-to-any switching and 
VLAN
 architecture, you can 
switch other topologies in the 
LAN
 to Frame Relay. The following diagram shows a typical 
WSX
 setup using a 56 Kbps Frame Relay line (up to 2 Mbps access rates are supported).
