This chapter describes the function and displays the syntax for Virtual Private Dialup Network commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Dial Solutions Command Reference.
To clear the content of the failure history table, use the clear vpdn history failure EXEC command.
clear vpdn history failureTo shut down a specified tunnel and all the MIDs within it, use the clear vpdn tunnel EXEC command.
clear vpdn tunnel network-access-server gateway-name
network-access-server | Name of the network access server at the far end of the tunnel, probably the point of presence of the public data network or the Internet service provider. |
gateway-name | Host name of home gateway at the local end of the tunnel. |
To display information about active Level 2 Forwarding (L2F) protocol tunnel and Level 2 Forwarding (L2F) message identifiers in a virtual private dialup network, use the show vpdn EXEC command.
show vpdnTo show the content of the failure history table, use the show vpdn history failure with the optional username keyword EXEC command.
show vpdn history failure [username]
username | (Optional) Specifies the username. The specified username helps to display only the entries mapped to that particular user. |
To specify the characters to be use to delimit the domain prefix or domain suffix, use the vpdn domain-delimiter global configuration command.
vpdn domain-delimiter characters [suffix | prefix]
characters | One or more specific characters to be used as suffix or prefix delimiters. Available characters are %, -, @, \ , #, and /. If a backslash (\) is the last delimiter in the command line, enter it as a double backslash (\\). |
suffix | prefix | (Optional) Usage of the specified characters. |
To enable virtual private dialup networking on the router and inform the router to look for tunnel definitions in a local database and on a remote authorization server (home gateway), if one is present, use the vpdn enable global configuration command.
vpdn enableTo cause the home gateway to issue its own CHAP challenge even if one has already been issued from the network access server, use the vpdn force-local-chap global configuration command. To disable the home gateway's issuing its own CHAP challenge, use the no form of this command.
vpdn force-local-chapTo set the failure history table depth, use the vpdn history failure table-size global configuration command.
vpdn history failure table-size entries
entries | Defines the number of entries. Valid entries are 20 to 50. |
To specify the local name to use for authenticating and the virtual template to use for building interfaces for incoming connections when a Level 2 Forwarding (tunnel) connection is requested from a certain remote host, use the vpdn incoming global configuration command.
vpdn incoming remote-name local-name virtual-template number
remote-name | Case-sensitive name of the remote host requesting the connection. |
local-name | Case-sensitive local name to use when authenticating back to the remote host. |
virtual-template number | Virtual template to use for building interfaces for incoming calls. |
To enable local authentication of users on the network access server before the connection is forwarded to the home gateway, use the vpdn local-authentication global configuration command. To reset the network access server to the default in which local authentication is disabled, use the no form of this command.
vpdn local-authenticationTo enable the logging of VPDN events, use the vpdn logging global configuration command. To disable the logging of VPDN events, use the no form of this command.
vpdn logging [local | remote]
local | (Optional) Log VPDN events locally. |
remote | (Optional) Log VPDN events to a remote tunnel endpoint. |
To enable the logging of failure events to the failure history table, use the vpdn logging history failure global configuration command. To disable the logging of failure events, use the no form of this command.
vpdn logging history failureTo specify use of Dialed Number Information Service (DNIS) or use of a domain name when selecting a tunnel for forwarding traffic to the remote host (the home gateway) on a virtual private dialup network, use the vpdn outgoing global configuration command.
vpdn outgoing {dnis dialed-number | domain-name} local-name ip ip-address
dnis dialed-number | Dialed number to be used for selecting a specific tunnel to be used for forwarding traffic to a home gateway. |
domain-name | Case-sensitive name of the domain to forward traffic to. |
local-name | Case-sensitive local name to use when authenticating the tunnel to the remote host. |
ip ip-address | IP address of the remote host (home gateway). |
To specify how the service provider's network access server is to perform VPDN tunnel authorization searches, use the vpdn search-order global configuration command. To remove a prior specification, use the no form of the command.
vpdn search-order {dnis domain | domain dnis | domain | dnis}
dnis domain | Search first on the Dialed Number Information Service (DNIS) information provided on ISDN lines and then search on the domain name. |
domain dnis | Search first on the domain name and then search on the DNIS information. |
domain | Search on the domain name only. |
dnis | Search on the DNIS information only. |
To set the source IP address of the network access server, use the vpdn source-ip global configuration command.
vpdn source-ip address
address | IP address of the network access server. |
