Configuration -WAN Access
Step 1 Run:
system-view
The system view appears.
Step 2 Run:
interface atm interface-number
The ATM interface view appears.
Step 3 Run:
loopback { local | payload | remote }
The command configures the Loopback mode.
You use the loopback function is generally specific test purposes:
• local : indicates the internal loop used to detect whether the local service chip is normal.
• payload : indicates the outer loop used to detect whether the payload is normal.
• remote : indicates the outer loop used to detect whether the remote is normal.
By default, no loopback is enabled on the ATM E3 interface.
