ILMI 4.0 and the SmartSwitch 9500 System
By default, the SmartSwitch 9500 is an SVC-only switch. This means that no VPI/VCI pairs are reserved
for PVCs. Before the user can create a PVC, the default ILMI settings must be changed to reserve
VPI/VCI pairs for PVC use.
Local management of the SmartSwitch 9500 allows the user to specify minimum and maximum values
for VCI and VPIs for all SVCs and SPVCs that the SmartSwitch 9500 will use while establishing
connections.
Table 1
provides the default settings ILMI uses when first connected to the ATM network.
Table 2
displays the available range of VCI/VPI pairs that may be configured for requested connections.
Table 1 Default Minimum and Maximum VCI and VPI Values for SVCs and SVPCs
Table 2 Minimum and Maximum VCI and VPI Ranges
The main purpose of the ILMI Configuration Menu screen is to limit the range of VPI/VCI pairs for SVC
connections. In the default setting, there are no VPI/VCI pairs reserved for PVCs. Refer to
Figure 1
