Configuring ATM Cell Packing over MPLS on a Port
Port mode cell packing allows multiple cells coming into an ATM interface to be packed into an MPLS
packet and transported over the MPLS backbone to an egress ATM interface.
To configure port mode, you issue the xconnect command from an ATM main interface and specify the
destination address and the VC ID. The syntax and semantics of the xconnect command are the same as
for all other transport types. Each ATM port is associated with one unique pseudowire VC label.
Perform this task to configure cell packing ATM over MPLS in port mode.
Restrictions
•
In cell packing, only cells from the same VC/VP can be packed into one MPLS packet. Cells from
different connections cannot be concatenated into the same MPLS packet
How to Configure AToM VCs on the 4-Port ATM ISE Line Card
Purpose
Sets up the cell-packing timers, which specify how long the PE
router can wait for cells to be packed into an MPLS packet.
You can set up to three timers. For each timer, you specify the
maximum cell packing timeout (MCPT). This value gives the cell
packing function a limited amount of time to complete. If the
timer expires before the maximum number of cells are packed
into an AToM packet, the packet is sent anyway. The range of
values is from 2 to 4095.
Specifies that the PVP is dedicated to transporting ATM cells. The
l2transport keyword indicates that the PVC is a switched PVC
and not a terminated PVC.
Enables cell packing and specifies the cell packing parameters.
The cells value represents the maximum number of cells to be
packed into an MPLS packet. The range is from 2 to 28.
The timer value allows you to specify which timer to use.
Binds the attachment circuit to a pseudowire VC or VP.
