Configuring a VC Class and Specifying the Basis for PVC Selection
To configure a VC class and specify the basis for PVC selection, enter the following commands
beginning in global configuration mode:
Command
Purpose
Step 1
Router(config)#
vc-class atm
name
Creates or modifies a VC class and enters VC class configuration
mode.
name
is the name of the VC class.
Step 2
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.
Step 3
Router(config-vc-c)#
mpls
experimental
[
other
|
range
]
(Optional) Configures Multiprotocol Label Switching (MPLS)
experimental (EXP) levels for a VC class that can be assigned to
a VC bundle and thus applied to all VC members of that bundle.
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 4
Router(config-vc-c)#
precedence
{
level
|
other
}
(Optional) Configures the precedence levels for a bundle member.
This command configures precedence-based PVC selection.
level
specifies the precedence level or levels for this bundle
member. Valid values are from 0 to 7.
You can configure a PVC bundle member with a single
precedence level (0), multiple individual precedence levels
(0,2,3), a range of precedence levels (0-2), multiple ranges of
precedence levels (0-2,4-5), or a combination of individual levels
and level ranges (0,1,2-4,7).
Note
This command is available when the PVC bundle match
type is set to
precedence
.
other
specifies that this bundle member handles all of the
remaining precedence levels that are not explicitly configured on
any other bundle members.
Note
Critical non-IP traffic automatically uses precedence
level 0.
