Port Configuration
This view displays external MIB objects
corresponding to the DLCI that the port
represents. This view is divided into several
sections. The Port Information and the External
Port Management sections of this view are unique
to the StComDLCIPort Model.
The Port Information panel has the following
fields:
• Admin Status: This indicates whether a user
can create, delete, modify, test, or have write-
only privileges for the DLCI port.
• Oper Status: This indicates the actual state of
the port.
• In-Service: The amount of time the connection
has been in service.
• Congest Mins: The number of minutes in
which 50% or more frames are tagged FECN
by the port.
• Tx FECNs: The number of frames transmitted
out the port with the FECN bit set.
The External Port Management panel has the
following fields.:
BC: (Burst Committed) The minimum number of
bits that a service provider guarantees for a given
permanent virtual circuit.
BE: (Burst Excess) The maximum number of bits
that may be sent in excess of BC. These bits are
most likely to be discarded during periods of
congestion.
CIR: (Committed Information Rate) The minimum
rate (bits/sec) of service that a service provider
guarantees for a given permanent virtual circuit.
PIR: (Peak Transmit Bandwidth) The maximum
rate (bits/sec) that bits will travel.
QIR: (Transmit Quiescent Information Rate)
Specifies (in bits/sec) how much data can be sent
after a period of silence. This parameter improves
performance for bursty data. When a switch
receives an initial burst of data from a Frame
Relay device, it sends this data out on the
network at a rate set by the QIR parameter. This
rate is usually set higher than the CIR but lower
than the PIR.
MIR: (Minimum Transmit Bandwidth) Represents
the lowest information rate (bits/sec) assigned
when there is congestion on the network.
