Configuring VC Bundling
To configure the VC bundle, use the following commands, beginning in global configuration mode:
VC Bundle Examples
The VC bundle configuration, shown in
Figure 25-10
, has eight PVCs bundled into one multipoint
subinterface at ATM 9/0/0 on the enhanced ATM router module. The PVCs have the IP precedence set
to the following applications:
•
IP precedence 7, 6, 5, and 3 used for the voice application
•
IP precedence 4 used for the video application
•
IP precedence 2 used for the high priority applications
•
IP precedence 1 and 0 are used for all remaining (default) applications
Command
Purpose
Step 1
Switch(config)#

subcard
/
port
.
subinterface#
multipoint
Switch(config-subif)#
Creates the ATM Router Module point-to-multipoint
subinterface and enters subinterface mode.
Step 2
Switch(config-subif)#
ip address
ip-address mask
Provides a protocol address and subnet mask for the
client on this subinterface.
Step 3
Switch(config-subif)#
bundle
name
Switch(config-if-atm-bundle)#
Creates the VC bundle changes to VC bundle
configuration mode.
Step 4
Switch(config-if-atm-bundle)#
protocol
{
ip-address
|
ip

Configures the VC bundle protocol.
Step 5
Switch(config-if-atm-bundle)#
oam-bundle manage
frequency-seconds
Enables end-to-end F5 OAM loopback cell
generation and OAM management for all VCs in the
VC bundle.
Step 6

Switch(config-if-atm-member)#
Configures the VC bundle member and changes to
VC bundle member configuration mode.
Step 7
Switch(config-if-atm-member)#
precedence
{
other |
range
} Configures the precedence level associated with the
VC bundle member.
Step 8
Switch(config-if-atm-member)#
bump
{
implicit | explicit
precedence-level
| traffic
}
Configures the bumping rules (switching if a VC
fails) for a specific VC bundle member.
Step 9
Switch(config-if-atm-member)#
protect
{
group | vc
}
Configures the VC to belong to a protected group or
to be individually protected.
Step 10
Switch(config-if-atm-member)#
exit
Switch(config-if-atm-bundle)#
Exits back to VC bundle configuration mode to
configure another PVC in the bundle.
