• Configuring L2TPv3 Control Channel Authentication Parameters
• Configuring L2TP Control Channel Maintenance Parameters
After you enter L2TP class configuration mode, you can configure L2TP control channel parameters in
any order. If you have multiple authentication requirements you can configure multiple sets of L2TP
class control channel parameters with different L2TP class names. However, only one set of L2TP class
control channel parameters can be applied to a connection between any pair of IP addresses.
Configuring L2TP Control Channel Timing Parameters
The following L2TP control channel timing parameters can be configured in L2TP class configuration
mode:
• Packet size of the receive window used for the control channel
• Retransmission parameters used for control messages
• Timeout parameters used for the control channel
This task configures a set of timing control channel parameters in an L2TP class. All of the timing
control channel parameter configurations are optional and may be configured in any order. If these
parameters are not configured, the default values are applied.
