VP Mode Configuration Guidelines
When configuring ATM Cell Relay over MPLS in VP mode, use the following guidelines:
•
You do not need to enter the encapsulation aal0 command in VP mode, but only AAL0 encapsulation
is supported with MPLS l2transport.
•
One ATM interface can accommodate multiple types of ATM connections. VP cell relay and VC cell
relay can coexist on one ATM interface.
•
If a VPI is configured for VP cell relay, you cannot configure a PVC using the same VPI.
•
VP trunking (mapping multiple VPs to one emulated VC label) is not supported in this release. Each
VP is mapped to one emulated VC.
•
Each VP is associated with one unique emulated VC ID. The AToM emulated VC type is ATM VP Cell
Transport.
•
The AToM control word is supported. However, if a peer PE does not support the control word, it is
disabled. This negotiation is done by LDP label binding.
•
VP mode (and VC mode) drop idle cells.
VP Mode Configuration Example
The following example transports single ATM cells over a virtual path:
Router(config)# pseudowire-class vp-cell-relay
Router(config-pw)# encapsulation mpls
Router(config-pw)# exit
Router(config)# interface atm 1/2/0.1 multipoint
Router(config-if)# atm pvp 1 l2transport
Router(config-if)# xconnect 10.0.0.1 123 pw-class vp-cell-relay
Verifying ATM Cell Relay VP Mode
The following show atm vp command shows that the interface is configured for VP mode cell relay:
Router# show atm vp 1
ATM5/0 VPI: 1, Cell Relay, PeakRate: 149760, CesRate: 0, DataVCs: 1, CesVCs: 0, Status:
ACTIVE
VCD VCI Type InPkts OutPkts AAL/Encap Status

7 4 PVC 0 0 F4 OAM ACTIVE
TotalInPkts: 0, TotalOutPkts: 0, TotalInFast: 0, TotalOutFast: 0,
TotalBroadcasts: 0 TotalInPktDrops: 0, TotalOutPktDrops: 0
