PVC Connections Switch Administration
–•
Configure the workstations for the same subnet and VPI/VCI pair = 0/101.
The broadcasting workstation on port A1 can send traffic to the receiving workstations on ports B2, B3, and C1.
4.5.3 Connecting to Local Switch Client Through a PVC
All PVC connections to the SmartCell ZX-250 local clients use B4 (the CPU port) as the HighPort.
Follow these instructions to connect an end node to a SmartCell ZX-250 local client through a point-to-point PVC.
s•
Use
add pvc
to create the PVC.
SmartCell ZX # add pvc

Use
add ipatmclient

T•
Connect the end node to port A1 of the SmartCell ZX-250.
Q•
Configure the end node with IP address 10.1.1.22, subnet mask 255.0.0.0, and VPI/VCI pair = 0/100.
4.5.4 Non-zero VPIs
The SmartCell ZX-250 uses 12 bits to define VPI/VCI pairs. The
vccmask
determines how many of the 12 bits are used
for the VPI and how many are used for the VCI. The
vccmask
uses a 2-bit register to hold four different VPI/VCI 12-bit
combinations. Table 4-1 shows the registers and the values that come preconfigured on the SmartCell ZX-250.
