Example 952 show isdn status Command Output

r5#show isdn status

Global ISDN Switchtype = basic-ni ISDN BRIO interface dsl 0, interface ISDN Switchtype = basic-ni Layer 1 Status:

ACTIVE Layer 2 Status:

TEI = 70, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED TEI = 71, Ces = 2, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED Spid Status:

spidl configured, spid1 sent, spid1 valid Endpoint ID Info: epsf = 0, usid = 2, tid = 1 TEI 71, ces = 2, state = 5(init)

spid2 configured, spid2 sent, spid2 valid Endpoint ID Info: epsf = 0, usid = 4, tid = 1 Layer 3 Status:

0 Active Layer 3 Call(s) Activated dsl 0 CCBs = 0

The Free Channel Mask: 0x80000003 Total Allocated ISDN CCBs = 0

Now remove both the global interface switch types for r5 in Example 9-53. Example 9-53. Removing the ISDN Switch Types r5(config)#interface bri0 r5(config-if)#no isdn switch-type

Warning: No ISDN switch-type defined. No calls possible. r5 (config-if)#exit

Dec 23 07:09:52.456: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BR0, TEI 70 changed to down

Dec 23 07:09:52.460: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BRI 0, TEI 70 change to down

Dec 23 07:09:52.628: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BR0, TEI 71 changed to downleshooting tools and utilities

Dec 23 07:09:52.632: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BRI0, TEI 71 change to down r5(config)#no isdn switch-type

Warning: No ISDN switch-type defined. No calls possible, unless switchtype define Globally and/or per interface.

This change will take full effect upon reload. r5 (config)#end r5#copy running-config startup-config r5#reload r5#show isdn status

**** No Global ISDN Switchtype currently defined ****

ISDN BRIO interface dsl 0, interface ISDN Switchtype = none Layer 1 Status: DEACTIVATED !!!now define your switch type and test r5#configure terminal r5(config)#isdn switch-type basic-ni

Dec 23 07:17:13.171: %ISDN-6-LAYER2UP: Layer 2 for Interface BRO, TEI 72 changed to up

Dec 23 07:17:13.339: %ISDN-6-LAYER2UP: Layer 2 for Interface BRO, TEI 73 changed to up r5(config)#end r5#copy running-config startup-config

The main complication to note is that when you completely remove the ISDN switch type the route you that no ca lis are poss ible. It also does uot take effect untii you reload the router. Just like othe features, however, you may run into slight differences with the version of code.
