Configuring the AIP
To create a PVC on the AIP interface, you use the atm pvc command as follows:
where:
•
•
•
•
•
•
•
•
To remove a PVC, use the no form of this command, as follows:
Following is an example of the atm pvc command:
The atm pvc command creates PVC n and attaches the PVC to VPI and VCI. The AAL used is
specified by aal and encapsulation by encap. A rate queue is used that matches the peak and average
(avg) rate selection. The peak and avg rate selection values are specified in kbps. Not specifying a
peak and avg value causes the PVC to default to the highest bandwidth rate queue available.
Note
disallowed.
Configuring the VP Filter
The vp-filter command configures the hexadecimal value used in the virtual path (vp) filter register
in the reassembly operation. When a cell is received, the right half (most-significant byte) of the filter
is exclusively NORed with the incoming virtual path identifier (VPI). The result is then ORed with
the left half (least-significant byte) of the filter (the mask). If the result is all ones, then reassembly
is done using the VCI/MID table. Otherwise, reassembly is done using the VPI/VCI table.

Router(config-if)# atm pvc vcd vpi vci aal-encap protocol-type-for-mux [ peak-rate ]
[ average-rate ] [ cell-quota ]
vcd is a per-AIP unique index value describing this VC in the range of 1 to MAXVC.
vpi is the ATM network VPI to use for this VC, in the range of 0 through 255.
vci is the ATM network VCI to use for this VC, in the range of 0 through 65,535.
aal-encap is the ATM adaptation layer encapsulation type to use on this VC from the following:
— aal5mux specifies the MUX-type for this VC. A protocol type must be specified.
— aal5snap specifies that LLC/SNAP precedes the protocol datagram.
— aal5nlpid specifies that NLPID precedes the protocol datagram.
— aal34smds specifies that SMDS framing precedes the protocol datagram.
— qsaal is a signaling type VC.
protocol-type-for-mux is a protocol type compatible with the MUX and is required from the
following protocols: ip, decnet, novell, vines, xns.
peak-rate is the (optional) maximum rate, in kbps, at which this VC can transmit data.
average-rate is the (optional) average rate, in kbps, at which this VC will transmit data.
cell-quota is an (optional) integer value, in the range 1 through 2047, describing the maximum
number of credits that a VC can accumulate. The AIP makes use of this in multiples of 32 cells.
Every cell transfer consumes one cell credit. One cell transfer credit is issued to a VC in the
average rate speed.
