Configuring L2Tp Control-Channel Maintenance Parameters - Cisco CRS Configuration Manual

Configuring L2TP Control-Channel Parameters
Specifies the L2TP class name and enters L2TP class configuration mode.
Step 8 no digest [ secret [ 0 | 7 ] password [ hash { md5 | sha } ]
Example:
RP/0/RP0/CPU0:router(config-l2tp-class)# no digest secret cisco hash sha1
Disables L2TPv3 control-channel authentication or integrity checking.
Step 9
Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
Step 10
show l2tp tunnel brief
Example:
RP/0/RP0/CPU0:router# show l2tun tunnel brief
Displays the current state of L2 tunnels and information about configured tunnels, including local and remote L2 Tunneling
Protocol (L2TP) hostnames, aggregate packet counts, and control-channel information.
Tunnels should no longer be using the old control-channel authentication password. If a tunnel does not update to show
that only one secret is configured after several minutes have passed, that tunnel can be manually cleared and a defect
report should be filed with TAC.
Issue this command to ensure that all tunnels are using only the new password for control-channel authentication.
Note
The output displayed for each tunnel in the specified L2TP class should show that one secret is configured.
