Advanced Configuration at LAC or LNS 613
By default, the interval for sending the tunnel Hello message is 60 seconds. If this
configuration is not implemented, LAC or LNS will adopt the default value as the
interval to send the Hello message to the peer.
Configure Domain
Delimiter and Searching
Order
This configuration is applicable to LAC only.
If there are a lot of users dialing in domain name mode, it is time-consuming to
search users in sequence. Therefore, it is recommended to set the necessary
searching policies (e.g., prefix and suffix delimiters) at LAC side to speed up the
searching.
The delimiters fall into prefix delimiter and suffix delimiter, including @, # , & and /.
The user with prefix delimiter can be “3Com.com#vpdnuser” and correspondingly
the suffix delimiter will be “vpdnuser@3Com.com”. During the searching,
separating user name from prefix/suffix delimiter, based on the defined rules will
greatly speed up the searching.
In domain name mode, there are four optional searching rules on condition that
the prefix/suffix delimiter is set:
■ dnis-domain (Search according to dialed number first, then according to
domain name)
■ dnis (Search according to dialed number only)
■ domain-dnis (Search according to domain name first, then according to dialed
number)
■ domain (Search according to domain name only)
Perform the following configurations in system view.
Table 678 Set Domain Name Delimiter and Searching Order
The l2tp match-order command merely configures the order of dialed number
and domain name for searching. In an actual searching process, the searching is by
all means conducted according to the full user name first, and then the configured
order of this command.
By default, search according to dialed number prior to domain name.
Disconnect Tunnel by
Force
This configuration is applicable to LAC and LNS.
When the number of users decreases to 0, or faults occur on the network, or
administrator takes the initiative to disconnect the tunnel, the tunnel will be
cleared. Either LAC or LNS can originate the request of clearing the tunnel. The
end receiving the request of clearing should transmit acknowledgement
