Configuring the Interfaces
Configuring the Interfaces
When the switch is powered on initially without any previous configuration data, the ATM interfaces are automatically configured on the physical ports. ILMI and the physical card type are used to automatically derive the ATM interface type, UNI version, maximum virtual path identifier (VPI) and virtual channel identifier (VCI) bits, ATM interface side, and ATM UNI type.
Default ATM Interface Configuration Without Autoconfiguration
If ILMI has been disabled or if the connecting end node does not support ILMI, the following defaults are assigned to all CES T1 and CES E1 interfaces:
•

ATM interface type = UNI
UNI version = 3.0
Maximum VPI bits = 8
Maximum VCI bits = 14
ATM interface side = network
ATM UNI type = private
Loopback = no loop
Signaling mode = no signaling
Data format = clear channel
Timing = synchronous
Line build out = 0 to 110 feet
Cell delay variation = 2,000 microseconds
Channel associated signaling = false
Partial fill = 47
