DETAILED STEPS
Configuring the Xconnect Attachment Circuit for ATM Cell Packing over L2TPv3
The ATM Cell Packing over L2TPv3 feature allows multiple ATM frames to be packed into a single
L2TPv3 data packet. ATM cell packing can be configured for Port mode, VP mode, and VC mode.
Perform one of the following tasks to configure the ATM Cell Packing over L2TPv3 feature:
• Configuring Port Mode ATM Cell Packing over L2TPv3, page 45
• Configuring VP Mode ATM Cell Packing over L2TPv3, page 47
• Configuring VC Mode ATM Cell Packing over L2TPv3, page 48
Configuring Port Mode ATM Cell Packing over L2TPv3
Perform this task to configure port mode ATM cell packing over L2TPv3.
SUMMARY STEPS
1. enable
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface type slot/port
Example:
Router(config)# interface ATM
4/1
Specifies the interface by type, slot, and port number, and enters interface
configuration mode.
Step 4
xconnect peer-ip-address vcid
pw-class pw-class-name
Example:
Router(config-if)# xconnect
10.0.3.201 888 pw-class
atm-xconnect
Specifies the IP address of the peer PE router and the 32-bit VCI shared
between the PE at each end of the control channel.
• The peer router ID (IP address) and virtual circuit ID must be a unique
combination on the router.
• pw-class pw-class-name—The pseudowire class configuration from
which the data encapsulation type (L2TPv3) will be taken. The pw-class
parameter binds the Xconnect statement to a specific pseudowire class.
The pseudowire class then serves as the template configuration for all
attachment circuits bound to it.
Note The L2TPv3 session can also be provisioned manually. See the section
“Manually Configuring L2TPv3 Session Parameters” for information
about manually configuring the L2TPv3 session parameters.
