Verifying ATM AAL5 SDU Mode over L2TPv3 Configuration Example
To verify the configuration of a PVC, use the show atm vc command in privileged EXEC mode:
Router# show atm vc
VCD/ Peak Avg/Min Burst
Interface Name VPI VCI Type Encaps Kbps Kbps Cells Sts
2/0 pvc 9 900 PVC AAL5 2400 200 UP
2/0 4 9 901 PVC AAL5 149760 N/A UP
The following show l2tun session command output displays information about ATM VC mode
configurations:
Router# show l2tun session brief
Session Information Total tunnels 1 sessions 2
