Tab Name
Specifies the ILMI and OAM
parameters.
ILMI – Management Information
Base (MIB) that provides status
and communication information
to ATM UNI devices and
provides a port keep-alive
protocol.
OAM – Sets the alarm functions
that generate Operations,
Administration, and Maintenance
(OAM) alarms.
Note: The B-STDX 9000 does not
support ATM SVC signaling
functions.
Sets the Optimum Trunk VPI.
Sets the threshold parameters
(mild, severe, and absolute) and
closed loop congestion controls
that determine how the switch
responds to congestion in the
network.
Sets the DCE and DTE polling
timer and interval values.
Specifies the service class type
that the logical port can support.
The valid values and their
corresponding definitions are
mono-class and multi-class.
When you configure the port for
mono-class operation, it only
supports VFR-NRT mode; when
configured for multi-class
operation, it can support constant
frame rate (CFR), VFR-RT,
VFR-NRT, and unspecified frame
rate (UFR) services.
