class applied to the PVC, and the configuration performed to the ATM class applied to the ATM
interface.
• All the configurations directly performed to the PVC, performed to the ATM class applied to the PVC,
and performed to the ATM class applied to the ATM interface take effect if they do not conflict.
• For different configurations performed to a PVC, the ATM class applied to the PVC, and the ATM
class applied to the ATM interface, if the configurations conflict with each other, those applied first
take effect, and the conflict prompt appears when the rest are performed.
• When an ATM class is applied to a PVC, no message is prompted no matter whether or not the
ATM class is successfully applied.
• Error messages appear when configurations performed to a PVC are invalid.
To configure an ATM class:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Create an ATM class and
enter ATM class view.
atm class atm-class-name N/A
3. Specify ATM AAL5
encapsulation type for the
PVC.
encapsulation aal5-encap
Optional.
By default, aal5snap
encapsulation is adopted.
4. Start transmission of OAM F5
Loopback cells or
retransmission check of OAM
F5 Loopback.
oam frequency frequency [ up
up-count down down-count
retry-frequency retry-frequency ]
Optional.
By default, OAM F5 Loopback cell
transmission is disabled. However,
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.
5. Set the PVC's service type and
rate-related parameters.
• Set the PVC's service type to
constant bit rate (CBR):
service cbr output-pcr
• Set the PVC's service type to
unspecified bit rate (UBR), and
set the rate-related parameters:
service ubr output-pcr
• Set the PVC's service type to
nrt-VBR, and set the
rate-related parameters:
service vbr-nrt output-pcr
output-scr output-mbs
• Set the PVC's service type to
rt-VBR, and set the rate-related
parameters:
service vbr-rt output-pcr
output-scr output-mbs
Optional.
By default, the service type of a
PVC is UBR.
You can use these four commands
to set the service type and the
parameters concerning
transmission rate. A newly
configured service type overwrites
the existing one.
