IfIndex
The ifIndex Value of the ifEntry this  virtual
circuit is layered onto.
Dlci
The Data Link Connection Identifier  for  this
virtual circuit.
State
Indicates whether the particular virtual  cir-
cuit  is operational.  In the absence of a Data
Link Connection Management  Interface,  virtual
circuit  entries  (rows) may be created by set-
ting virtual  circuit  state  to  'active',  or
deleted by changing Circuit state to 'invalid'.
Whether or not the row actually  disappears  is
left  to the implementation, so this object may
actually read as 'invalid' for  some  arbitrary
length  of  time.   It is also legal to set the
state of a virtual  circuit  to  'inactive'  to
temporarily disable a given circuit.
Enumerations:
  • invalid (1)
  • active (2)
  • inactive (3)
ReceivedFECNs
Number of frames received from the network in-
dicating  forward  congestion since the virtual
circuit was created.
ReceivedBECNs
Number of frames received from the network in-
dicating  backward congestion since the virtual
circuit was created.
SentFrames
The number of frames sent  from  this  virtual
circuit since it was created.
SentOctets
The number of octets sent  from  this  virtual
circuit since it was created.
ReceivedFrames
Number of frames received  over  this  virtual
circuit since it was created.
ReceivedOctets
Number of octets received  over  this  virtual
circuit since it was created.
CreationTime
The value of sysUpTime when the  virtual  cir-
cuit was created, whether by the Data Link Con-
nection Management Interface  or  by  a  SetRe-
quest.
LastTimeChange
The value of sysUpTime when last there  was  a
change in the virtual circuit state
CommittedBurst
This variable indicates the maximum amount  of
data,  in  bits,  that  the  network  agrees to
transfer under normal  conditions,  during  the
measurement interval.
ExcessBurst
This variable indicates the maximum amount  of
uncommitted data bits that the network will at-
tempt to deliver over the measurement interval.
By default, if not configured when creating the
entry, the Excess Information Burst Size is set
to the value of ifSpeed.
Throughput
Throughput is the average number of 'Frame Re-
lay  Information  Field'  bits  transferred per
second across a user network interface  in  one
direction, measured over the measurement inter-
val.
If the  configured  committed  burst  rate  and
throughput  are  both non-zero, the measurement
interval
T=frCircuitCommittedBurst/frCircuitThroughput.
If the  configured  committed  burst  rate  and
throughput  are  both zero, the measurement in-
terval
T=frCircuitExcessBurst/ifSpeed.
RouteType
Type of routing entry. This field is intended for
informational purpose only.
Enumerations:
  • local (1)
  • switch (2)
RouteIfIndex
The destination IfIndex is a pointer to either a
second frame relay interface (frame relay switching)
or to a frame relay virtual interface (multiprotocol
routing).
RouteDlci
The destination DLCI. When the circuit is used for
switching, all packets are sent using this DLCI.
This field is void for multiprotocol routing.
