ATM PVC Selection
Configuring an ATM Bundle Member Using a VC Class
To configure an ATM bundle member using a VC class, perform the following configuration tasks:
•
Configuring an ATM VC Class, page 19-25
•
Attaching a VC Class to an ATM Bundle Member, page 19-27
Configuring an ATM VC Class
To configure an ATM VC class and specify the basis for ATM PVC selection, enter the following
commands beginning in global configuration mode:
Step 8
Router(config-atm-vcb-vc)#
protect
{
group
|
vc
}
Configures the bundle member as part of the protected group of a
bundle or as an individually protected VC in a bundle.
group
configures the VC or PVC bundle member as part of the
protected group of the bundle.
vc
configures the VC or PVC member as individually protected.
Step 9
Router(config-atm-vcb-vc)#
ubr
[
pcr
]
(Optional) Configures unspecified bit rate (UBR) as the traffic
shaping rule for the VC.
(Optional)
pcr
is the peak cell rate (PCR).
Step 10
Router(config-atm-vcb-vc)#
ubr+
pcr
[
mcr
]
(Optional) Configures UBR plus (UBR+) as the traffic shaping
rule.
pcr
is the peak cell rate (PCR)
(Optional)
mcr
is the minimum cell rate (MCR).
Step 11
Router(config-atm-vcb-vc)#
vbr-nrt
pcr
scr
[
mbs
]
(Optional) Configures variable bit rate-nonreal-time (VBR-nrt) as
the traffic shaping rule.
pcr
is the peak cell rate (PCR).
scr
is the sustaining cell rate (SCR).
(Optional)
mbs
is the maximum burst size (MBS).

Router(config-vc-c)#
oam-bundle
[
manage
]
[
frequency
]
Enables end-to-end F5 Operation, Administration, and
Maintenance (OAM) loopback cell generation and OAM
management for a VC class that can be applied to a VC bundle.
(Optional)
manage
enables OAM management. If you omit this
keyword, loopback cells are sent, but the bundle is not managed.
(Optional)
frequency
is the number of seconds between
transmitted OAM loopback cells. Valid values are from 0 to 600
seconds. The default is 10 seconds.
