Configuring Virtual Connections
The following example shows how to configure the ATM VP tunnel on the ATM switch router (SB-1)
interface ATM 0/0/0, VPI 99:
Switch(SB-1)(config)# interface atm 0/0/0
Switch(SB-1)(config-if)# atm pvp 99
Switch(SB-1)(config-if)# exit
Switch(SB-1)(config)# interface atm 0/0/0.99
Switch(SB-1)(config-subif)# end
Switch(SB-1)#
Displaying the VP Tunnel Configuration
To show the ATM virtual interface configuration, use the following EXEC command:
Command
show atm interface atm
card/subcard/port.vpt#
The following example shows the ATM virtual interface configuration for interface ATM 1/0/0.99:
Switch# show atm interface atm 1/0/0.99

Configuring a Shaped VP Tunnel
This section describes configuring a shaped VP tunnel for a single service category with rate-limited
tunnel output on a switch.
A shaped VP tunnel is configured as a VP of the CBR service category. By default, this tunnel can carry
VCs only of the CBR service category. However, you can configure this VP tunnel to carry VCs of other
service categories. The overall output of this VP tunnel is rate-limited by hardware to the peak cell rate
(PCR) of the tunnel.
Shaped VP tunnels are supported only on systems with the FC-PFQ feature card. (Catalyst 8510 MSR
Note
and LightStream 1010)
A shaped VP tunnel is defined as a CBR VP with a PCR. The following limitations apply:

A maximum of 64 shaped VP tunnels can be defined on each of the following interface groups:
(0/0/x, 1/0/x), (0/1/x, 1/1/x), (2/0/x, 3/0/x), (2/1/x, 3/1/x), (9/0/x, 10/0/x), (9/1/x, 10/1/x),
(11/0/x, 12/0/x), and (11/1/x, 12/1/x). (Catalyst 8540 MSR)
A maximum of 64 shaped VP tunnels can be defined on interfaces x/0/y; similarly, a maximum of
64 shaped VP tunnels can be defined on interfaces x/1/y. (Catalyst 8510 MSR and
LightStream 1010)
The bandwidth of the shaped VP tunnel is shared by the active VCs inside the tunnel in strict
round-robin (RR) fashion.
