Assigning a
Transmission Priority to
an ATM PVC
To do...
Start transmission and
retransmission detection of
operations, administration, and
maintenance (OAM) F5
Loopback cells
Set the parameters for AIS/RDI
alarm cell detection
Set the PVC Set the PVC's
service type service type to
and the constant bit rate
rate-related (CBR)
parameters
Set the PVC's
service type to
unspecified bit
rate (UBR), and
set the relevant
rate parameters
Set the PVC's
service type to
variable bit
rate-non real
time (VBR-NRT),
and set the
relevant rate
parameters
Set the PVC's
service type to
variable bit
rate-real time
(VBR-RT), and
set the relevant
rate parameters

"AAA/RADIUS/HWTACACS Configuration" on page
You can assign transmission priority to ATM PVCs associated with the UBR, VBR-T,
or VBR-NRT service. At the time of bandwidth allocation, the PVC with higher
priority has priority over other PVCs.
Follow these steps to assign a transmission priority to the ATM PVC:
Use the command...
oam frequency
frequency [ up up-count
down down-count
retry-frequency
retry-frequency ]
oam ais-rdi up
up-count down
down-count
service cbr output-pcr
[ cdvt cdvt-value ]
service ubr output-pcr
service vbr-nrt
output-pcr output-scr
output-mbs
service vbr-rt
output-pcr output-scr
output-mbs
1751.
Remarks
Optional
By default, OAM F5 Loopback
cell transmission is disabled, but
if an OAM F5 Loopback cell is
received, it should be
responded.
By default, up-count is 3,
down-count is 5 and
retry-frequency is 1 second.
Optional
By default, AIS/RDI alarm cell
detection is enabled, which
means the PVC goes down
when the number of AIS/RDI
alarm cells received reaches
down-count and goes up if no
AIS/RDI alarm cell is received in a
period specified by the up-count
argument (in seconds).
Optional
By default, the service type of a
PVC is UBR.
The CDVT is 500μs by default.
You can use these four
commands to set the service
type and the parameters
concerning transmission rate.
Note that a newly configured
service type overwrites the
existing one.
