Possible CDP bug? Check it out! [7:59929]
I've run into this situation while doing some practicing with the 3550s and some routers 2611--3550---35503640 all ethernet ports are set at full duplex 10 megabit speed. the 2611 and the 3640 are connected via a vlan tunnel. everything is working fine, until I turn on l2protocol-tunnel cdp on both switches, at which point I get the following error: 3640 FrameSwitch# 1w0d: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/1 (not hal f duplex), with Router_14_2611 Ethernet0/1 (half duplex). 2611 1w0d: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/1 (not ful l duplex), with FrameSwitch Ethernet0/1 (full duplex). as near as I can tell, there are no errors on any of the interfaces. no collisions, etc. not that I'm sending a lot of traffic during these studies, but extended pings don't come up with anything either. relevant configurations for all interfaces. as you can see, everything agrees all along the line. everyone is set for speed 10 and duplex full. if I turn off l2protocol-tuinnel cdp on the interfaces, the error messages disappear. I suspect a bug in CDP, but I'm wondering if I have missed anything. 2611 --- interface Ethernet0/1 no ip address full-duplex ! interface Ethernet0/1.1 encapsulation dot1Q 121 ip address 122.1.1.1 255.255.255.0 ! interface Ethernet0/1.2 encapsulation dot1Q 122 ip address 122.1.2.1 255.255.255.0 ! interface Ethernet0/1.3 encapsulation dot1Q 123 ip address 122.1.3.1 255.255.255.0 ! interface Ethernet0/1.4 encapsulation dot1Q 124 ip address 122.1.4.1 255.255.255.0 !

There is a subtlety here, which may be getting hidden by the fact that labs and the test facility are mostly or completely routers, rather than hosts. If you think about it, the proper place to limit MTU (other than for medium conversion) is not on the router, but on the host. Admittedly, not all hosts have the ability to set their MTU. There is a TAC guide for altering host TCP/IP parameters, but for some obscure reason, it's buried under OSI Application Services: http://www.cisco.com/en/US/tech/tk472/tk473/technologies_tech_note09186a008011a218.shtml Another subtlety is that there can be very good reasons either to have different control and forwarding paths. I need to check into the details, but one approach might be to leave the basic MTUs at 1500 or so, but limit the MTU on MPLS or other tunnels such that host path MTU discovery gets a limit on data MTU size. A non-scalable (in the core) way to do things would be to policy route based on protocol type and associated MTU. Routing traffic gets handled differently than data traffic -- that's inherent in the IP precedence field, where the top two levels are reserved for control traffic. > > > >> > I have a home lab where OSPF is running find over frame-relay hub and >> spoke >> > configuration.

Query on VOIP [7:59933]
Hello all!! I am working for a carrier company who uses ip network consisting of Cisco Routers to transport voice calls.The company deals mainly with pre-paid calling cards.The customer buys the card and dials a toll free no. to make a voice call or makes a call thro a dialer program(Installed on the pc) which sends the calls thro the ip network.When i make a call from a dialer on a pc which has a dialup connection,then absolutely there is no problem. But when I make a call from a pc which is on the Home LAN then only the destination party is able to hear my voice.I am not able to hear their voice.We r not using any firewalls as of now in the home but may go for it in the future.Nat has been configured on our home router and we hv a DSL connection to the ISP.I am not able to figure out the problem.can someone help me in identifying the problem Thanx in advance..

Not be limited to Boson 2. Not come from the vendor I'll also throw out a general question. A post not long ago asked to compare the labs of one vendor versus another, and I am affiliated with one of the two. The question was "which is better," and, if I responded, I would have said they really can't be compared directly, because they are designed for different learning objectives. Would such a comment from the designer be acceptable? In other words, no direct competitive analysis, but just a statement of the design philosophy? While I think such information would be useful, I'd rather not see it posted that trigering a series of "mine is better than yours" posts.

simple network setup [7:59937]
Hi, I just thinking a simple question for a while... If I have only single router with 2 serial connection to Single ISP and no BGP was configured. Can inbound and outbound traffic be load balanced by only using 2 static routes on both routers? Also, what happen if either link is down? any packet will be lost?

RE: Collision [7:59590]
A late addition to the thread... Priscilla is correct about using full duplex if it's a point to point link - as long as the other end supports full duplex - not all of the older routers do. Another point to note is that the reported reliability of this link is only 250/255. Anything less than 255/255 is usually Not A Good Thing in my experience. But yeah, as at least one other poster has said - clear your counters and have another look to see what's happening NOW. JMcL Priscilla Oppenheimer wrote: > > The interface is set to half duplex.

RE: Caller ID [7:59602]
Going through the old posts... You may need to get your ISDN provider to set this up. It may be an extra cost feature. If it's working, you should be able to see the number using "show isdn active" or similar. It may depend on the switch type for all I know - I'm used to ETSI.

RE: FR Low Latency Queuing (LLQ) [7:59820]
This is something I am researching currently. I believe LLQ is CBWFQ+PQ and the PQ is strict. This means that anything above the allocated rate is dropped. This is fine for voice traffic where you reserve say 200kbps for 8 voice calls, and anything more than that is dropped, but not suitable for data applications. You will need to use CBWFQ for your data apps, not place them in the PQ. The CBWFQ will guarantee bandwidth to PC1 as you mention in your first post. I would say that the PQ only gives you 30k due to slow start after packet loss. Finally, why CBWFQ gives you sometimes 100k, sometimes 50k, - I can understand it giving you more than 80k, if there is more available, but I'm not sure why it gave you less. Perhaps the application or operating system applied some congestion control. I believe Win2k or XP does a lot of good work to not hog all of the WAN bandwidth. At this stage, I would question the appropriateness of FTP as an accurate traffic generation tool. As to the ping times, your bandwidth under the priority condition is only guaranteed up to the amount reserved. Anything above that is dropped if the Q is strict. PC1 would get better response if the ping traffic was in the PQ, but it isn't so it is placed in the same Q as all the FTP traffic. Then within the PQ, your ping has to sit at the end of a bunch of FTP data. I wouldn't be surprised if your ping traffic from PC1 was actually worse that PC2. PC2, under CBWFQ, would be more fair to small ping packets than many large FTP packets.

RE: simple network setup [7:59937]
Yes you can load share - but it wouldn't load share any individual flow - I believe this ensures the order of packet arrival is correct. If a link went down, I'm not sure about the packets in the interface queue (ie, those that had been placed on the outbound interface queue) but I would suspect they would be lost, so yes, you may lose a packet or two.

OK, Howard, I'll bite on this one, especially as seeing we had some conversation off line on this very topic. I for one would love to see some interaction between the various purveyors of CCIE Lab prep materials regarding their products and the thought processess behind them. Not a sales pitch, but rather a discussion of the kinds of things that are included in their labs, why, and what skill set they believe is necssary for the attainment of the CCIE. As I said privately, I don't know how much ice anything I say might cut, as I have not succeeded as yet. But if I were asked today, I would say that there are just a couple of keys - mastery of the "core topics" which are pretty much discernable from any of the practice lab workbooks, or from Caslow, and then also a GOOD Lab methodology, or game plan. I can't say much about the core topics publicly because it could be construedas an NDA violation, but anything regarding game plan is fair game. BTW, I am not so sure I agree that lab writing is a CCIE skill set. I'd like you to elaborate more on why you believe that the ability to write a good lab is indicative of CCIE level skill. Maybe some other folks have some thoughts on this as well. Hell, maybe Paul would let this particualr discussion cross post to the CCIE Lab list, where the vast majority of CCIE Lab candidates associate.

RE: FR Low Latency Queuing (LLQ) [7:59820]
Hi All, Thanks all information. I am a little bit confused about LLQ. Below is my understanding after digesting some documentation and feedback from others. Please correct me if I'm wrong. 1. LLQ=PQ+CBWFQ and PQ is defined by using 'priority' 2. if using 'bandwidth', then I'm not using LLQ. What I'm using is CBWFQ. 3. PQ (from LLQ) defines the min. and max. guaranteed bandwidth to the traffic I defined during congestion. Also, do I need to define the class-default under policy? eg,policy-map 1 class 1 priority 80 class class-default fair-queue What's the difference if I'm not defining the class-default? Thanks again. rgds, ivan Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=59948&t=59820 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
