How can I tell if CDRouter is receiving any ATM packets?
ATMWhen CDRouter is configured with an ATM interface, it will display all packets that it is receiving using the buddy -pt or -decode options. Only AAL5 packets on the configured
PVC are displayed.
You can also check the driver stats to find out if the ATM connection is receiving any cells. In the /proc/net/atm directory of your Linux host, use the cat command to display your driver statistics. The name of the driver will vary depending on the ATM card you are using.
Example
[root@server lab]# cd /proc/net/atm/
[root@server atm]# ls

[root@server atm]# cat pca200e\:0
