In-Depth Information
The order in which dialer maps are configured can be important. If two or more dialer map commands
refer to the same remote address, the router or access server will try them one after another,
in order,
until a successful connection is established.
IOS can dynamically build dialer maps on a router receiving a call. The dialer map is built
based on the authenticated username and the negotiated IP address of the caller. Dynamic
dialer maps can be seen only in the output of the command
show dialer map
, and will not
appear in the running configuration of the router or access server.
Note
Command Syntax
To configure a serial interface or an ISDN interface to call one or multiple sites, or to receive calls from
multiple sites, use a form of the
dialer map
interface configuration command; all options are shown in
the first form of the command. Table 16-8 lists the dialer map syntax descriptions. To delete a particular
dialer map entry, use a
no
form of this command:
dialer map
protocol next-hop-address
[name
hostname
] [
spc
] [speed 56 | 64]
[broadcast] [modem-script
modem-regexp
] [system-script
system-regexp
]
[
dial-string
[:
isdn-subaddress
]]
To configure a serial interface or ISDN interface to place a call to multiple sites and to authenticate calls
from multiple sites, use the second form of the
dialer map
command:
dialer map
protocol next-hop-address [
name
hostname] [
spc
] [speed 56 | 64] [broadcast]
[dial-string[:isdn-subaddress]]
To configure a serial interface or ISDN interface to support bridging, use the third form of the command:
dialer map bridge
[
name
hostname
][
spc
] [broadcast] [
dial-string
[:
isdn-subaddress
]]
To configure an asynchronous interface to place a call to a single site that requires a system script or that
has no assigned modem script, or to multiple sites on a single line, on multiple lines, or on a dialer rotary
group, use the fourth form of the
dialer map
command:
dialer map
protocol next-hop-address
[
name
hostname
] [
broadcast
] [
modem-script
modem-regexp
] [
system-script
system-regexp
] [
dial-string
]
Table16-8 Syntax Description
protocol
Consists of protocol keywords; one of the following:
appletalk
,
bridge
,
clns
,
decnet
,
ip
,
ipx
,
novell
,
snapshot
,
vines
, and
xns
.
next-hop-address
Gives the protocol address used to match against addresses
to which packets are destined. This argument is not used
with the
bridge
protocol keyword.
name
(Optional) Indicates the remote system with which the local
router or access server communicates. Used for
authenticating the remote system on incoming calls.
