Basic ATM Connection Procedure
To set up an ATM connection, perform these steps:
Step 1
Activate a line by using the upln command.
Activating a line makes it available so you can configure it. Also, it starts statistics collection.
Subsequently, you can begin to add connections by using addcon.
You can verify that the line has been activated by using the dsplns command.
Step 2 Activate the ATM port by using the upport X.X command, where
X.X is the slot and port of the ATM card set.
Step 3 Use the cnfport command to establish the characteristics for the ATM port.
Step 4
If a suitable class is already configured, note its number and use this class when adding the ATM
connection by using the addcon command. (The dspcls command displays the parameters for each
connection class. The cnfcls command allows you to modify an individual class.)
Step 5 Use the vt command to log in to the node at the remote end of the proposed ATM connection.
Step 6 At the remote node, use the upln, upport, and cnfport commands, as listed in steps 1 and 2, to activate
and configure the remote port.
Step 7
Use the addcon command at one end of the connection to activate the ATM connection.
