nJose1(config-if)#dialer idle-timeout 60
Next, configure the DDR setting on the BRI interface. Use the dialer-group 1 command as
follows, to associate this interface with the already configured dialer-list 1:
SanJose1(config-if)#dialer-group 1
The dialer map command is used by DDR whenever the interface encounters interesting traffic.
Now, configure the dialer map for this interface:
SanJose1(config-if)#dialer map ip 192.168.16.3 name Capetown 5552000
Notice that this dialer map command is similar to the dialer maps that were created in previous labs.
However, since a modem is not used, no modem-script is required.
Finally, activate the BRI 0/0 interface with the no shutdown command. Once the BRI interface is
activated, the router will send the SPIDs to the ISDN switch. Informational messages should appear
on the screen stating the status of the BRI 0/0 is up, but its B channels, BRI 0/0:1, BRI 0/0:2, are
down. The following messages stating that the TEIs are up should be received:
01:26:09: %LINK-3-UPDOWN: Interface BRI0/0:1, changed state to down
01:26:09: %LINK-3-UPDOWN: Interface BRI0/0:2, changed state to down
01:26:09: %LINK-3-UPDOWN: Interface BRI0/0, changed state to up
01:26:09: %ISDN-6-LAYER2UP: Layer 2 for Interface BR0/0, TEI 64 changed to up
01:26:09: %ISDN-6-LAYER2UP: Layer 2 for Interface BR0/0, TEI 65 changed to up
If the preceding messages do not appear, or error messages appear, troubleshoot as necessary.
Next, use the show isdn status command to get more specific information regarding the
established connection with the ISDN switch. The following shows a sample output:
SanJose1#show isdn status
Global ISDN Switchtype = basic-ni
ISDN BRI0/0 interface
dsl 0, interface ISDN Switchtype = basic-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 64, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI = 65, Ces = 2, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Spid Status:
TEI 64, ces = 1, state = 8(established)
spid1 configured, spid1 sent, spid1 valid
Endpoint ID Info: epsf = 0, usid = 70, tid = 1
TEI 65, ces = 2, state = 8(established)
spid2 configured, spid2 sent, spid2 valid
Endpoint ID Info: epsf = 0, usid = 70, tid = 2
Layer 3 Status:
0 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
If the SPID status is not established or, if the SPID configuration on the router is changed, issue the
clear interface command to force the router to resend the SPID to the switch. Executing this
command once should be sufficient. However, when using the Atlas 550 with the Cisco IOS, it may
be necessary to repeat the command a second or third time.
SanJose1#clear interface bri0/0
