Configuring L2TP Control Channel Maintenance ParametersSUMMARY STEPSDETAILED STEPSThe L2TP hello packet keepalive interval control channel maintenance parameter can be configured inL2TP class configuration mode.This task configures the interval used for hello messages in an L2TP class. This control channelparameter configuration is optional. If this parameter is not configured, the default value is applied.1. enable2. configure terminal3. l2tp-class [l2tp-class-name]4. hello intervalStep 1Step 2Command or ActionenableExample:Router> enableconfigure terminalPurposeEnables privileged EXEC mode.• Enter your password if prompted.Enters global configuration mode.Step 3Step 4Example:Router# configure terminall2tp-class [l2tp-class-name]Example:Router(config)# l2tp-class class1hello intervalExample:Router(config-l2tp-class)# hello 100Specifies the L2TP class name and enters L2TP classconfiguration mode.• The l2tp-class-name argument is optional. However, ifyou want to configure multiple L2TP classes you mustspecify a unique l2tp-class-name for each one.(Optional) Specifies the exchange interval (in seconds) usedbetween L2TP hello packets.• Valid values for the interval argument range from 0 to1000. The default value is 60.Configuring the L2TPv3 PseudowireThe pseudowire class configuration procedure creates a configuration template for the pseudowire. Usethis template, or class, to configure session-level parameters for L2TPv3 sessions that are used totransport attachment circuit traffic over the pseudowire.The pseudowire configuration specifies the characteristics of the L2TPv3 signaling mechanism,including the data encapsulation type, the control protocol, sequencing, fragmentation, payload-specificoptions, and IP properties. The setting that determines if signaling is used to set up the pseudowire isalso included.58
