Chapter 19 Configuring Quality of Service for PVC Bundles
ATM PVC Selection
Step 3
Router(config-atm-vcb)#
pvc-bundle
pvc_name
[
vpi
/
]{
vci
}
Adds the specified VC to the bundle if it does not exist already
and enters ATM bundle VC configuration mode.
pvc-name
is a name that you can use to refer to the PVC.
vpi
/
is the virtual path identifier (VPI). The slash is required.
vci
is the virtual channel identifier (VCI).
Step 4
Router(config-atm-vcb-vc)#
bump
{
explicit
level
|
implicit
|
traffic
}
(Optional) Configures the bumping rules for the bundle member.
The default is implicit bumping.
explicit
level
specifies the precedence, experimental (EXP), or
differentiated services code point (DSCP) level to which traffic on
the PVC is bumped if the PVC goes down. You can specify only
one service level for bumping. For PVC bundles that use
precedence or EXP mapping, valid values for
level
are from 0 to
7. For PVC bundles that use DSCP mapping, valid values are from
0 to 63.
Note
When the PVC goes down, the router directs the traffic to
a PVC mapped with the service level you configure in
explicit
level
.
implicit
applies the implicit bumping rule, which is the default,
to a single bundle member. The implicit bumping rule stipulates
that bumped traffic is to be carried by a PVC that has the lower
precedence level.
traffic
specifies that the PVC accepts bumped traffic. By default,
a PVC accepts bumped traffic.
Note
To configure a PVC to reject bumped traffic from another
bundle member, enter the
no bump traffic
command.
Step 5
Router(config-atm-vcb-vc)#
mpls
experimental
[
other
|
range
]
(Optional) Configures Multiprotocol Label Switching (MPLS)
experimental (EXP) levels for the bundle member. This command
configures MPLS EXP-based PVC selection.
(Optional)
other
specifies any MPLS EXP levels that are not
explicitly configured. This is the default setting.
(Optional)
range
specifies a single MPLS EXP level (2) or a range
of levels (1-3). Valid values are from 0 to 7.
Step 6
Router(config-atm-vcb-vc)#
precedence
[
other
|
range
]
(Optional) Configures the precedence levels for the VC bundle
member. This command configures precedence-based PVC
selection.
(Optional)
other
specifies any precedence levels that are not
explicitly configured. Valid values are 0 to 7.
(Optional) range specifies a single precedence level. Valid values
are from 0 to 7, specified either as a single number (3) or a range
of precedence levels (2-4).
Step 7
Router(config-atm-vcb-vc)#
class
class-name
Attaches a VC class to the PVC bundle member.
class-name
is the name of the VC class.
