ADC SWD4573I1 Manuale Utente

The following table describes the information displayed after you type a show pvp command:

Configure primary PVCCs and backup PVCCs using the command-line interface. Backup 
PVCCs are redundant to primary PVCCs. A primary PVCC automatically switches to a backup 
PVCC if the primary PVCC were to fail.

PVCCs carry data between defined points within the Avidia chassis, such as between a channel 
card and a line card (see 

 for creating 

cross-connects from a frame-based channel card). PVCCs also carry data from subscriber 
modems to Avidia channel cards, and from Avidia line cards to other destinations in the ATM 
backbone network.

PVCC configuration requires specifying a VPI and VCI. VPI and VCI combinations must be 
unique only on the same user port, as the circuit is remapped to a different VPI and VCI on the 
network interface. This enables different subscribers to use the same VPI and VCI combinations 
without creating conflict in the network.

Index

The PVPC table index number of the displayed PVPC.

Source Port

The subscriber-side port number.

VPI

The subscriber-side VPI.

Destination Port

The network-side port number.

VPI

The network-side VPI.

TxTraffic Index

The ATM traffic profile assigned for transmitted 
(downstream) data.

RxTraffic Index

The ATM traffic profile assigned for received 
(upstream) data.

Admin

The configured status of the PVPC, either up 
(activated) or down (deactivated).

Oper

The current operational status of the PVPC, either up 
(PVPC is passing data) or down (PVPC is not passing 
data).
