RE: ISDN interface problem
Hello, First problem I see is 'Layer 1 DEACTIVATED'. Here is the link and suggestion to this problem from Cisco: http://www.cisco.com/warp/public/779/smbiz/service/troubleshooting/ts_isdn.h tm Using Show Commands To Troubleshoot ISDN Networks The show commands in the Cisco IOS that are most helpful in solving ISDN problems tell you whether you are connected to the local ISDN switch - show isdn status, or whether you have successfully made a call - show dialer. Show ISDN Status Command Upon getting the ISDN line provisioned by telco, the only parameters that are required for the router to synchronize with the switch are the switch type and the spid(s). Sample configuration would be: isdn switch-type basic-ni1 ! interface BRI0 isdn spid1 4112120101 5551212 isdn spid2 4112130101 5551213 After proper configuration, output from the show isdn status EXEC command would yield: The current ISDN Switchtype = basic-ni1 ISDN BRI0 interface Layer 1 Status: ACTIVE Layer 2 Status: TEI = 112, State = MULTIPLE_FRAME_ESTABLISHED TEI = 113, State = MULTIPLE_FRAME_ESTABLISHED Layer 3 Status: No Active Layer 3 Call(s) Activated dsl 0 CCBs = 0 Total Allocated ISDN CCBs = 0 --> Failure of the Cisco router to synchronize properly with the ISDN switch would yield: The current ISDN Switchtype = basic-ni1 ISDN BRI0 interface Layer 1 Status: DEACTIVATED Layer 2 Status: Layer 2 NOT Activated Layer 3 Status: No Active Layer 3 Call(s) Activated dsl 0 CCBs = 0 Total Allocated ISDN CCBs = 0 If you receive this output, the possible causes are: - Problem Suggested Action Faulty CableReplace the cable from router to ISDN jack, making sure the cable contains the middle two pins (pins 4 & 5 in an RJ-45 cable). Wrong Switch Type or Spid(s)Contact telco and confirm switch type and spid(s). Re-enter them into router and issue the clear interface bri number EXEC command. Faulty ISDN lineGet an analog phone and plug into ISDN jack. You should get either 1) a clicking noise, or 2) white noise/light static. If you do not get either of those, it is not an active ISDN line. Contact telco and open trouble ticket. -- Mike Munoz * -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Hans Stout Sent: Friday, July 21, 2000 9:48 AM To: [EMAIL PROTECTED] Subject: ISDN interface problem Hi there colleagues, I have a problem with my ISDN interface on a Cisco 2610 router. I just had a Telekom engineer at the site verify that the line is ok to the interface, but he cannot see any lights burning on the intreface (B1 and B2 LEDs). When I do a sh isdn status, I get the following: Ener_Erkath#sh isdn status Global ISDN Switchtype = basic-net3 ISDN BRI0/0 interface dsl 0, interface ISDN Switchtype = basic-1tr6 Layer 1 Status: DEACTIVATED Layer 2 Status: Layer 2 NOT Activated Layer 3 Status: 0 Active Layer 3 Call(s) Activated dsl 0 CCBs = 0 The Free Channel Mask: 0x8003 Total Allocated ISDN CCBs = 0 When I change the ISDN switchtype to basic-net3, it doesn't change the status of the ISDN. Here is the output from the sh int bri0/0: Ener_Erkath#sh int bri0/0 BRI0/0 is standby mode, line protocol is down Hardware is PQUICC BRI Internet address is 10.90.1.70/30 MTU 1500 bytes, BW 64 Kbit, DLY 2 usec, rely 255/255, load 1/255 Encapsulation PPP, loopback not set Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/0/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 21036936 packets output, 2224160372 bytes, 0 underruns 0 output errors, 0 collisions, 3 interface resets 0 output buffer failures, 0 output buffers swapped out 140 carrier transitions Does anybody know if this could just mean that the interface is not functioning at all ? What do the carrier transitions mean ? And what does 'standby mode' mean ? I am also not able to bounce the interface (shutdown/no shutdown doesn't change the status on the interface, it remains in standby mode). Thanks for your help in advance ! Regards, Georg __

RE: about the utilization rate of bandwidth
Ask when the client is seeing slow response. During this time, do a 'show interface' command and look at the 5 min input and output rate. Add these together and you can see what the current utilization is. Compare them to the bandwidth on the line. If it is Frame Relay, make sure you ask the client where he is trying to reach and check the routers at both ends and anything in between.

RE: CCNA 1.0 vs. 2.0
I took the CCNA 2.0 beta (passed) and used Todd Lammle's study guide for 640-407. A couple of months ago Lammle was on brainbuzz.com and suggested a few extra subjects that were on the test. -brainbuzz transcripts- Q: wl1516 Hey Todd,when is you new CCNA book coming out and what is different from old book? Speaker: tlammle I have added a chapter on layer two swtiching, VLANs, STP and ISL. Coming out in May. Just use the Lammle study guide and search cisco.com for the above subjects and you should be ok. I also have experience but the guides should be sufficient. Good luck and get experience so Cisco certs aren't watered down.
