Configuring An Atm Class - H3C SR6600 Configuration Manual

To do...
Configure the maximum
number of PVCs allowed on
the ATM interface
This command applies to both a main ATM interface and its subinterfaces. However, you cannot
configure this command in ATM subinterface view.

Configuring an ATM Class

An ATM class facilitates ATM configuration. Configurations of PVC MAP, encapsulation type, OAM
loopback, and service category can be implemented via an ATM-Class. First create an ATM class and
set the parameters needed, and then call the ATM class in PVC view or ATM interface view.
Follow these steps to configure an ATM class:
To do...
Enter system view
Create an ATM class and enter
ATM class view
Specify ATM AAL5 encapsulation
type for the PVC
Start transmission of OAM F5
Loopback cells or retransmission
check of OAM F5 Loopback
Set the
PVC's
service type
and
rate-related
parameters
pvc max-number max-number
system-view
atm class atm-class-name
encapsulation aal5-encap
oam frequency frequency [ up
up-count down down-count
retry-frequency retry-frequency ]
Set the PVC's
service type to
service cbr output-pcr
constant bit rate
(CBR)
Set the PVC's
service type to
unspecified bit rate
service ubr output-pcr
(UBR), and set the
rate-related
parameters
Set the PVC's
service type to
variable bit
service vbr-nrt output-pcr
rate-non real time
output-scr output-mbs
(nrt_VBR), and set
the rate-related
parameters

Required
Optional
By default, aal5snap encapsulation
is adopted.
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.
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. Note that a
newly configured service type
overwrites the existing one.
