RE: DLSW ? [7:52674]
Hi, I am using DLSW over frame relay already. Works great. From what I can remember, DLSW+ establishes a TCP connection between the 2 routers, leaving the SNA on the LAN's -Original Message- From: Adam Frederick [mailto:[EMAIL PROTECTED]] Sent: 04 September 2002 18:37 To: [EMAIL PROTECTED] Subject: DLSW ? [7:52674] I just have a curiousty question. Hopefully you can help me out... Current Setup: Site A is connecting to Site B via Frame-Relay and is only transporting SNA. Of course w/ SNA you have a SNA server and assign all users a LU. We are getting ready to take out all SNA and make this IP that's flowing across the Frame.. but it's still SNA on my provider side. I'm curious as to how they are going to accomplish this. They require we use a specific naming convention on all our Win2K machines. I'm thinking they're going to use DLSW+ ? Any input is greatly appreciated. If you need more info, please ask, I'm kinda in a hurry!

RE: CAT6500 rebooting into boot mode [7:52654]
First, what is the config-register set to on that MSFC? Is that why a reload is causing it to go to ROM monitor? (should probably be 0x2102) In other words, are these two seperate issues? Is it returning to monitor any time it relaods. or just after this failure? As far as the Nortel router causing an MSFC reload to begin with because of an OSPF topology change... Reconvergence shouldn't cause this, but... Since you provided no version info, you might want to use the Bug Toolkit to see if you can find an issue with OSPF causing reloads on your version of code. Also, does the MSFC indicate the reason for the reload when you do a 'show ver'? Is there a crashinfo file that the MSFC saved? If so, it will likely show the specific cause and you can research thast also.

RE: how can i erase flash mem for a router which doesn [7:52677]
Well, isn't it likely that the problem is exactly what the error is telling you? You have 32MB memory. The Max on a 1710 is 48MB. Does that image require 48? Actually, I can't even find the 1710 in the upgrade planner. If I select a 1720 instead, and then change the URL to indicate a 1710 instead of a 1720, it shows no images in the 12.2 trian, but the minimum version for a 1710 per the compatability matrix is 12.2. Strange! Anyway, I think it's just a memory issue like the error says. Didn't yuou save a copy of the existing image before erasing the flash to load the new image?

It is a memory area that is structured not for fast lookup in forwarding, but for ease of updating with new routes. It's often structured as some kind of linked list/tree. The FIB may be implemented in software or hardware. You can display it with various show cache commands. It is designed for very fast lookup of destinations and associated output interfaces while actually forwarding packets. Typically, it's structured as some sort of hash table. In dCEF, there are multiple copies of the FIB in each VIP. Some kinds of FIBs contain only a subset of the routes known to the RIB, and updating them selectively versus deleting and rebuilding them from the RIB is a challenge. In CEF, there is a one-to-one correspondence between RIB and FIB entries, so the "cache miss" problem never happens.

Help needed [7:52699]
Hello Group, It would appreciated if anyone could shed some light on the following:- distribute-list X in - filters routes learned via all incoming interfaces from going into the routing table distribute-list X out - filters any external redistributed routes from other protocols. But for OSPF, is it true that... 1) distribute-list X in - will still filters routes from all incoming interfaces from entering into the routing table. I have read on Parkhurst (OSPF Command & Reference) saying that this command can filters "O" & "O IA" route, but not "O E2" routes, yet I have also read on other books saying that only "O IA" routes can be filtered by this, so which is correct? Also, since OSPF uses LSAs, where OSPF neighbors determines routes from the info in the Link State database, this command won't stop the routes from going into OSPF Topology database. 2) distribute-list X in - same as above, except the filtering only applied for routes learned via a specific interface. 3) distribute-list X out - I have read from different books (as well as CCO regarding this). Dr Parkhurst (OSPF Command & Reference) says that this command is useless / has no effect on OSPF... yet I have read on other posts saying this will still work, where ALL different external protocols will be filtered with the list (e.g. if EIGRP & RIP are both redistributed into OSPF, then they would both be filtered). 4) distribute-list X out - filters only a specific external redistributed protocol (O E2) from entering into the ASBR's own OSPF database, hence these external routes will be prevented to be advertised to the rest of OSPF domain.

RE: VOIP and subnets [7:52688]
John, One of the advantages of most IP phones is that you only need to run one connection per office. To facilitate this, IP phones often contain a two port hub or switch (one port to for LAN and the other for a user's computer.) In this scenario, the phone is in the same VLAN as the user's PC. As long as your network does not get too congested and especially if you have QoS capable switches, this should work fine. However, if you really want to spend time running twice as many connections and using twice as many ports, the phones and the PBX would be very happy on their own VLAN. -Joe FYI: Cisco mentions both options in: http://www.cisco.com/univercd/cc/td/doc/product/voice/ip_tele/avvidqos/qosph one.htm -Original Message- From: John Brandis [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 04, 2002 4:31 PM To: [EMAIL PROTECTED] Subject: VOIP and subnets [7:52688] Hi All, planning for my new corporate network, i have decided that the company needs 8 different networks to work efficiently, all vlans are class c's, such as 10.64.0.0 -10.64.7.254 I have planned this well, and have a plan to fit into my OSPF design.

RE: QOS certzone guide question [7:52681]
Sorry, I just re-read your post and realized what you were actually asking and I am sure there is someone more qualified than I to answer this, but, my understanding is that the FIB is a destination prefix cache used in high-speed forwarding or "switching" like CEF and the RIB is basically an older(?) version used by slower process switching and other CPU based decision making processes.

VOIP and subnets [7:52688]
Hi All, planning for my new corporate network, i have decided that the company needs 8 different networks to work efficiently, all vlans are class c's, such as 10.64.0.0 -10.64.7.254 I have planned this well, and have a plan to fit into my OSPF design. Today, just found out, that my company has just purchased 500 nec ip phones and the appropriate PBX. As I have no experience with voip, could some one please tell me, if its a best design principle, to have the IP phones in subnets of there own, such as VLAN 7 & 6, are just phones, nothing else ?

Re: Router IOS Upgrade bug in 12.1 images [7:52489]
This is not actually a bug.
Starting with 12.2(1) IOS, the 2600 and 3600 platforms support the
squeeze command. To get it to work, you have to reformat the flash
using a 12.2 image, which creates a log file used in the squeeze
process. That log is a few hundred K in size, and hidden.
The listed flash requirements for 12.2(8)Tx images is 16MB, and this is
part of the reason why ... even though technically it can fit in an 8MB
flash. It's also listed that way because future versions are not going
to fit in 8MB, even formatted with old flash.

Re: traffic shapping and rate-limit [7:52468]
Mohamed Saro wrote: > what is the difference and the direction of rate-limit and traffic shapping If you're looking for definitions, try this from RFC 3290 (p. 12): Diffserv nodes may apply shaping, policing and/or marking to traffic streams that exceed the bounds of their TCS in order to prevent one traffic stream from seizing more than its share of resources from a Diffserv network. In this model, Shaping, sometimes considered as a TC action, is treated as a function of queuing elements - see section 7. Algorithmic Dropping techniques (e.g., RED) are similarly treated since they are often closely associated with queues. Policing is modeled as either a concatenation of a Meter with an Absolute Dropper or as a concatenation of an Algorithmic Dropper with a Scheduler. These elements will discard packets which exceed the TCS. The glossary (section 2) also defines "work-conserving" and non-work-conserving", regarding whether or not packets will continue to be sent when the link is idle: Non-work- A property of a scheduling algorithm such that it conservingservices packets no sooner than a scheduled departure time, even if this means leaving packets queued while the output (e.g., a network link or connection to the next element) is idle. Work- A property of a scheduling algorithm such that it conservingservices a packet, if one is available, at every transmission opportunity. Shaping The process of delaying packets within a traffic stream to cause it to conform to some defined temporal profile. Shaping can be implemented using a queue serviced by a non-work-conserving scheduling algorithm. Those are the accepted definitions for purposes of clarifying the discussion of Diffserv. If someone wants to use a different definition, no problema, but we only need to know what it is. "All definitions are created equal." Some are used more than others, depending on the discussion. -- TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=52679&t=52468 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I'm curious as to how they are going to accomplish this. They require we use a specific naming convention on all our Win2K machines. I'm thinking they're going to use DLSW+ ?

Re: traffic shapping and rate-limit [7:52468]
On the outbounds side the ISP has already incurred the expense of transporting the outbound data to the edge router the customer is connected to. So delivering the traffic within reason would be in everyone's best interest. On the inbound side the pricing model for rate limited service which the customer wanted is such that taking more traffic than they are paying for would be financially unacceptable. Now of course as the ISP you could build into the price of service the overage traffic, but look at what that meansfirst you need to have backbone capacity for it since your backbone capacity planning metrics/plan won't easily account for drops and usage of various diffserv values mainly since a fully paying customer has much traffic with zero'ed diffserv values and may expect those values to hold true for one of thier egress circuits on your network(IP-VPN or other site-to-site). Then you're incurring expense of upgrading backbone circuits sooner. For most frame services you'll will build this into the cost structure since customers traffic CAN be shaped by the ATM core effectively, it's almost 100% on your network so the unit cost for bits above committed rates are much lower, and there are a controlled set of sink/sources based upon the PVC's the customers has purchased to make the capacity planning problem slightly more constrained. Hope this helps to explain why shape outbound and limit inbound. Of course there are good arguements for doing similar services in different ways, I was just trying to give the background for why many folks choose this method.

Re: Router IOS Upgrade bug in 12.1 images [7:52489]
Speaking about upgrade bugs, I've found upgrade bug in 12.2.
Here is what is happening, and how to overcome it.
Hardware:
-
2600 with 8 MB flash, 12.2(8)T1 telco IOS loaded.
Problem:
There is 8MB flash, and I want to load 12.2(8)T2. "show flash"
shows that flash is 8MB. Do "erase flash" to remove existing
image from flash. Now "show flash" shows that there is 7.8MB
free in flash, and 12.2(8)T2 cannot be loaded ("copy tftp flash"
says that there is no enough space). "squeeze" doesn't help.
Solution:
-
Load older IOS that fits into 7.8 MB, for example 12.0(7)T,
reload router, erase flash (now it will have 8 MB free), and
then load 12.2(8)T2.

OSPF Corruption or Duplicate Router ID? [7:52670]
All, Recently I had a situation where I mistakenly loaded a configuration from a TFTP server onto a box but that very config was already on another router. Thus, I ran into a number of problems. One of which was duplicare router ID messages. Although I had changed the loopback and all the other interfaces on this router to what it should have been, it still saw the router ID as a duplicate (a "show ip ospf interface" proved this). I did two things and I am not sure which one corrected the problem... 1) I applied "router-id xxx.xxx.xxx.xxx" (with the correct loop0 address) to apply the correct router-id. 2) I performed a "clear ip ospf process 100" in an effort to bounce the ospf process. Which one actually fixed the problem? Bouncing OSPF or the router ID change?

CAT 4912G interface failure [7:52669]
Hello Group, Gigabit interfaces of a Cat 4912G fails intermitently. Although the ports would still show connected but there would be no Layer 2 communication with directly connected neighbours. Different 1000-Base SX modules have been tested on different ports but still the same result. Anybody has had similar experience and if so what is the way out? Please help. Cisco Fresher.

Re: traffic shapping and rate-limit [7:52468]
It's my turn to disagree :). If we are going to consider quality of service from ISP point of view then don't you think that rate-limit is giving you the advantage of passing exceding traffic for your client after marking it such that if you do have free bandwidth as the ISP you can let this traffic through, and drop it if not? Using rate-limit in such a way means that you can think of charging your client more for giving him such an option. This is not acheivable using traffic-shapping as it just sets a threshold and drops packets exceeding that threshold. What you are doing means to me that you find traffic-shapping is better than rate-limitting so you are applying it on the outgoing traffic to the client. However, as it is unidirectional and you can't rely on asking the client to do it from his side also for the other direction so the only alternative is to rate-limit on the incoming traffic. Would you kindly explain to us why you find your way would provide a better quality from the ISP ? Regards, Yasser >From: Jay Greenberg > >I would have to disagree.

Re: traffic shapping and rate-limit [7:52468]
I would have to disagree. From an ISP standpoint, when we supply a capped service to a customer, we use a combination of rate-limiting and traffic shaping. I Rate-limit the input, and traffic shape the output. I suppose it is more resource-intensive on our end, however don't you agree that it is better quality of service from the ISP?

So no idea about it at > all Ali and Chuck, If you have the time, it might help if we can figure out how close the exam is to the blueprint of the DQOS 9E0-601 exam and the offical course description: http://www.cisco.com/warp/public/10/wwtraining/certprog/testing/current_exams/9E0-601.html http://www.cisco.com/pcgi-bin/front.x/wwtraining/CELC/index.cgi?action=CourseDesc&COURSE_ID=1582 Without violating the NDA, can you tell us how the exam compares to the lists at those URLs? I'm writing a summary QoS, policy, Diffserv and Intserv. I found that the single best perspective for that summary has been the Diffserv model in RFC 3290 (and the management discussion in RFC 3289): http://ietf.org/rfc/rfc3290.txt http://ietf.org/rfc/rfc3289.txt The model is somewhat abstract, but it really helps me make sense of the confusing QoS mess (see especially figures 1 and 2). It breaks QoS routing into ten "functional datapath elements" and the traffic control blocks (TCBs) that are constructed from the elements: Action-conditioning elements * classifiers * meters Action elements --- * DSCP markers * counters * droppers absolute * multiplexors * null action Queueing elements - * droppers algorithmic * queues (buffers) * schedulers For example: I was having difficulty with policing and shaping. Then I ran across this paragraph (RFC 3290, section 3.2, p. 12): Diffserv nodes may apply shaping, policing and/or marking to traffic streams that exceed the bounds of their TCS in order to prevent one traffic stream from seizing more than its share of resources from a Diffserv network. In this model, Shaping, sometimes considered as a TC action, is treated as a function of queuing elements - see section 7. Algorithmic Dropping techniques (e.g., RED) are similarly treated since they are often closely associated with queues. Policing is modeled as either a concatenation of a Meter with an Absolute Dropper or as a concatenation of an Algorithmic Dropper with a Scheduler. These elements will discard packets which exceed the TCS. That helps, doesn't it? I mean, if you can get a feel for the ten basic elements / operations, the TCBs, regardless of how complex they might be, can all be constructed from simple elements. The other question I have is: How much emphasis is put on the QoS management tools: QDM, QPM, SAA, IPM, SMS? They are all in CiscoWorks 2000 (SAA is native to IOS). Did you have an opportunity to practice QoS management with the tools in CiscoWorks? If not, do you think it would have made the test easier if you had access to those tools? -- TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=52662&t=52600 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

CCNP Lab [7:52660]
OK, I am looking in all of the nooks and crannies to put together a small setup. I have found a 2501 and a 2514. I don't know what's in them yet, but I will this afternoon. As far as putting together an environment that I can study for CCNP (I am taking the Routing exam soon) what else should I look for? I have to be minimalistic for now. Thanks in advance.

Good. > Counting on my fingers, I'm estimating that 60% of the next Lab I see will > be this good clean difficult but relevant stuff. Speaking of voice and its relationship to CCIE preparations: My lab partner and I started studying for the CCIE written exam this summer. We got the Bruno book and read it cover to cover -- well, maybe we skipped a few sections on SRB and other legacy issues. When we got to chapters 11 and 12 the world changed right before our eyes. The reality of AVVID struck. We put the CCIE on hold for a few months (years?) and are focusing on CIPTSS and, later, some sort of video certification. (That reminds me, I don't remember running across any video certs yet. For voice and general QoS knowledge, there's CIPTSS, CIPTOS, and CIPTDS. If someone would refer me to similar certs for video, I'd be most grateful.) My guess is that the more one learns about voice and video and the QoS mechanisms that support them in the network infrastructure, the better prepared for the CCIE exams he'll be. The Internet supports convergence; IP-based IETF networks are the workhorses that are fulfilling the vision of (B)ISDN without the lethargic baggage and behind-closed-door attitude of the ITU. For Cisco users and customers, this all boils down to AVVID. I wouldn't be surprised if they renamed the CCIE "CCAE" (Certified Cisco AVVID Expert). Just kidding about that, but AVVID will be one of the most important focal points for CCIE students. -- TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=52658&t=52651 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
