Alcatel Carrier Internetworking Solutions Switch/Router ユーザーズマニュアル

Page 29-7

The following diagram summarizes the self-configuration features of the 

WSX

. This example 

assumes no configuration parameters are entered for the 

WSX

. Default bridging is set up on 

Group 1, and no Routing or Trunking are configured.

After mapping virtual circuits to virtual ports, the 

WSX

 is ready to send data. 

STATUS ENQUI-

RIES

 are repeated periodically by the 

WSX

. The intervals between 

STATUS ENQUIRES

 can be 

configured through software. See Setting Configuration Parameters on page 29-22 for infor-
mation on setting these parameters.

Cable plugs into 

WSX

 serial port.

Board senses cable type
and adjusts circuitry.

The 

WSX

 sends 

STATUS ENQUIRY

message to Frame Relay network.
This message requests the DLCIs of
all virtual circuits and the active/
inactive status of the those VCs.

The Frame Relay network returns a

STATUS

 message that includes 

DLCIs

for all VCs on this physical port and
whether the VCs are active, inac-
tive, or deleted.

WSX

 maps each 

DLCI

 (virtual circuit)

to a virtual port within the switch. In
addition, all of these virtual ports are
assigned to default 

VLAN 1

.
