Command:

show dialer

 

Mode:

Router#


Syntax:

show dialer [interface type number]


Syntax Description:
interface Displays information for the interface specified by the arguments type and number


Command Description:

To display general diagnostic information for interfaces configured for DDR (dial-on-demand routing), use the show dialer command in EXEC mode.


Example:
The following is an output example from the show dialer command for a BRI interface when dialer profiles are configured:
Router#show dialer interface bri 0 
BRI0 - dialer type = ISDN
Dial String      Successes   Failures    Last called   Last status
0 incoming call(s) have been screened.
BRI0: B-Channel 1
Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (15 secs)
Dialer state is data link layer up
Dial reason: ip (s=6.1.1.8, d=6.1.1.1)
Interface bound to profile Dialer0
Time until disconnect 102 secs
Current call connected 00:00:19
Connected to 5773872 (wolfman)
BRI0: B-Channel 2
Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (15 secs)
Dialer state is idle


The following table describes significant fields shown in the display:

Table: Show Dialer Interface BRI Field Descriptions
Field Description

BRI0 - dialer type = ISDN

ISDN dialer.

Dial string

Dial strings of logged calls (telephone numbers). On ISDN BRI interfaces, if you have specified a subaddress number in the dialer string, this number is included in the dial string after a colon.

Successes

Successful connections (even if no data is passed).

Failures

Failed connections; call not successfully completed.

Last called

Time that last call occurred to specific dial string.

Last status

Status of last call to specific dial string (successful or failed).

0 incoming call(s) have been screened.

Number of calls subjected to Dialer Profiles screening to determine how the call is to be treated.

BRI0: B-Channel 1

Header indicating the following data is for B channel 1.

Idle timer (120 secs), Fast idle timer (20 secs)

Settings (in seconds) for the idle timer and the fast idle timer.

Wait for carrier (30 secs), Re-enable (15 secs)

Settings (in seconds) for the wait for carrier timer and the reenable timer.

Dialer state is data link layer up

The message "data link layer up" suggests that the dialer came up properly, if it says anything else then dialer did not come up properly. The message "physical layer up" means the line protocol (LCP) came up, but the NCP did not come up. The show interfaces command also provides the similar information.

Dial reason: ip (s=6.1.1.8, d=6.1.1.1)

What initiated the dial, namely an IP packet, plus source and destination address in the packet.

Interface bound to profile Dialer0

Dialer profile that is bound to this interface or B channel.

Time until disconnect

Time until line is configured to disconnect. This field is displayed if the interface is currently connected to a destination.

Current call connected

Time at which the current call was connected.

Connected to

Dial string to which line is currently connected.
