BGP Problem [7:6376]
We have a problem with BGP , We need your advice to isolate the cause and solve the problem . We have three downlinks and two upliks . We use BGP at one way for incoming traffics . So we advertise our own IPs through the three providers Interpacket , Netvision and paltel . We successfully do BGP peers with the three links . I do tests to see how the world see us . I do test from the site ( http://www.1anetworks.com/test1.htm ) . The result is that : 1- When the three links on ( BGP sessions ) Most of the world reach us through Interpacket . 2- I do individual Test for every BGP session alone . and all the three advertise our routes . 3- For example from Telehous1-UK the as-path =4 through Interpacket , as-path = 4 Through Netvision and = 6 from Paltel . 4- I prepend the routes through Interpacket so as-path =6 . the expect result must be that Telehous1-UK reach us through Netvision . But in fact the whole world still reach us through Interpacket Which means that the AS-PATH is not the factor in that issue. So What do you think the Cause . and What you advise us to do .

Dear Group I am having one 6509 switch with 2 sup module cards (one in redudent mode). All of a sudden from past couple of days i am observing that my SUP 1 modules status LED is not glowing. Same time my sup2 modules management LED is glowing RED. But still my switch is working fine. When I give SH MOD command it shows status as ok for all the cards including SUP MODULE 1. For sup mod 2 the status shows as standby. I am also having MSFC-2 and PFC cards in the same SUP modules. My both sup modules are exactly identical. Does that mean that either of mine sup module is faulty. Any mod can fail at any time ???. How can I verify that my modules are working fine. Does anybody faced problem like this. many thanks in advance regds Get free email and a permanent address at http://www.netaddress.com/?N=1 Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=6384t=6384 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: RE:ATM int are up, unable to ping. [7:5934]
Thanks all. I did notice the RX warning LED's on both routers being constantly on, and as soon as i keyed in atm clocking internal on one router, both LED's went away. I'm sure that Hutnik et. all just copied the config from a scenario that involved an ATM switch in the picture. I wasn't aware of the fact that you can't ping the local ATM or FR interface. I'll be searching CCO to find out the rational behind this.

[7:5934] ok, couldn't let this pass on a Friday afternoon. Went to the lab and set up 2 routers as beginning on page 283, Lab #17. No, it didn't work. I was using a 3600 and a 4700. I dropped the 3600 and used another 4700. Didn't work. However I noticed that when back-to-back both 4700's Rcv Alarm was flashing crazy as well as another led which I forget the name. I remembered a previous post about clock and gave the command atm clock internal on one router. Boom, lights are more sane and yes I can ping, from both routers to the other router. So, the lab is correct BUT they forgot the little thing about the clock if you're directly back-to-back. Plugged them both back into the LS-1010, took the clock off and things are back to normal.

Anyway, the adapter card will not enable, and when I do a show diag 1 I get this:(see below) show that it is powered off. I've searched everywhere to find the command to power it on. Any suggestions?

Switch Classification [7:6412]
May be a question already answered many times, but I was just curious to what classification a switch falls under? Is it usually referred to as a DCE or a DTE. I would think a DCE because when you connect a Switch(DCE) to a ROUTER (DTE, could be DCE) you use a straight. When connecting Switch(DCE) to Switch/Hub(DCE) you use a crossover. Could someone elaborate on this issue? Is my train of though wrong on this one? The only reason I'm asking is because I've never read anyone refer to it as a DCE, a better question is can it be reffered to as one? Another question (may be a little off topic from this discussion group) does anyone out there know a *nix platform that supports EtherChannel? I know Data ONTAP for Netapps support it, but I just wanted to know if there are any *nix that do. Thanks group. -- Sanity is calming, but madness is far more interesting.

RE: elementary? [7:6359]
Thanks everyone for their replies. As I now understand it, the 1Gb uplink just moves data faster than... say, a 100Mb uplink. Correct? Conversations between hosts on each switch still take place one at a time, thereby obeying Ethernet rules of one station transmitting at a time. Correct? Okay my next question. Is there any point at which this 1Gb uplink can become saturated, since it's only handling station to station sessions- one at a time. If a number of stations on each switch were doing large file transfers to each other via the uplink, would there be some point at which the uplink would be maxed out- in terms of bandwidth? Or is the only limiting factor, the workstations inability to pump data out fast enough to max out the uplink when they're only running 100Mb? I'm thinking that it's really not possible to max out a 1Gb uplink when stations are only running 100Mb. If this is correct then I lay this question to rest. Thanks.

RE: Does MPLS really live up to all its hype? [7:6151]
Actually, Cisco bought the ONS 15900 along with Monterey Networks for 500 million in August of 1999. That's what makes this a particularly interesting move by Cisco since this was an aquisition which places them in the market of one of the next big core technologies exactly following the corporate culture NRF mentioned. Core network technologies has always been their bread and butter and to see them dump the Monterey project after investing and aquiring the company just because of the economic slow down is questionable in my mind. Other companies have had it rough too. I've heard Lucent almost went bankrupt but as NRF pointed out they are still heavily investing in Lambda switching. It has been confirmed by the VP of Optical Networking that Cisco doesn't plan on reengaging the lambda switching market anytime soon. With a compound annual growth rate of 137% and an estimated 5.7 billion spent in optical switches by 2005 the question in my mind is...Is this an irresponsible move by a leader in the networking industry? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of NRF Sent: Tuesday, May 29, 2001 10:08 PM To: [EMAIL PROTECTED] Subject: Re: Does MPLS really live up to all its hype?

Well, I'm sure that everybody knows Cisco's corporate strategy has always been to try to figure out what's going to be hot, and then just acquire somebody. Sometimes it works (Grand Junction still being the best example), sometimes it doesn't. But I've never seen Cisco as much of a research-oriented company, at least not in the lines of Lucent, with its world-class Bell Labs, or Nortel. Rather, it is a sales/marketing driven company that also likes to play the acquisition card. So I'm sure that if and when lambda switching really gets big, Cisco will come calling, wallet in hand. The suits in Cisco must be thinking something like: This acquisition strategy has worked pretty well so far, so why not keep doing it? Of course, this strategy is not so easy to do when your stock price has crashed. Cisco better figure out how to get its market cap back up. Note - for would-be flamers - I am not commenting on whether Cisco's dumping of the 15900 was a smart or stupid thing. What I am saying is that doing so was perfectly in line with its corporate culture. And I'm sure we would all agree that it is extremely difficult for big companies to change their culture.

Re: Serial link redundancy [7:6413]
move two of the T-1s such that you have two circuits per router, and then run mHSRP (m for multiple or multigroup or similar) between the boxes. mHSRP is a method of running a pair of HSRP groups between the two routers, such that one router is active in each group in normal circumstances. To facilitate load-balancing, point half your machines at each of the HSRP addresses (ie as default gateways) - this is a little rough and ready, but is the simplest way to achieve what you want to do. When one box fails, the remaining box will become active on both HSRP groups. To permit failover for circuit failure, have the group on which the router would normally be active track the state of the WAN interface. With two circuits you can decide whether to fail over after the failure of one circuit, or make the priority decrement cumulative for the two circuits, such that failover will only occur after the failure of the second circuit. config somethiong like this R1: interface FastEthernet0/0 ip address 192.168.1.201 255.255.255.0 standby 1 priority 100 standby 1 ip 192.168.1.204 standby 1 track Serial0/1 45 standby 1 track Serial0/2 45 standby 1 preempt standby 2 priority 20 standby 2 ip 192.168.1.205 standby 2 preempt and vice versa on the other router. this is config is to failover after both circuits fail, to failover after a single failure, up the tracking decrement to 80. hth Andy - Original Message - From: Tony To: Sent: Wednesday, May 30, 2001 1:51 PM Subject: Serial link redundancy [7:6413] Quick question: I have two 3640's running HSRP.

I hate following up my own posts, but I went to one of my Linux boxes to see if there was a 'rarp' command. It turns out there is, and it works just like the arp command I listed below. The only problem was that I don't have rarp support compiled into my kernel, so I couldn't use it. The drawback to each of these commands, however, is that they don't perform an arp or rarp queries. They simply offer a means of displaying, or clearing, the entries in the arp or rarp tables. It doesn't really matter though...

If the entry doesn't already exist in the cache, it will perform the query without intervention.

Comrades... ;=) This discussion is humorous... it is like seeing two big American 4-wheel trucks driving down the city streets. One is Chevrolet and the other Ford. Each has a window sticker showing a territorial mark on the other vehicles emblem. Ford marking territory on the Chevrolet emblem and the Chevrolet marking territory on the fords. Both are consuming massive amounts of fuel and both arguing which vehicle is better... All the while the manufacturers are laughing up a party as they watched their indoctrinated groupies battle. It does not matter which vehicle you drive... you can even drive both. I enjoy NT for some things and UNIX for other things. Both have strengths and weaknesses. The best thing about both O/S's is that they both keep the income flowing... drive your Chevy, drive your Ford... I just pay the bills and let the manufactures enjoy the party less. P.S.

Re: O.T : Heart By-pass Surgery...Anyone got any links???? [7:6442]
Hi, i have seen recently a vast amount of non-cisco related questions recently and i thought that i would try my luck my uncle needs some heart surgery and was wondering if anyone has some advise. Well, I'm not sure exactly what you are asking, but both having done some biomedical engineering and also having been through angioplasties, bypass, pacemakers, and various research procedures... Is it like BGP or OSPF routing when trying to track a blood clott... left ventricle first..unless there is a weight on the right... No, it's more like static routing. There is also separation of the control and forwarding planes. In the forwarding plane, venous blood (veins flow to the heart, arteries flow from the heart), enters the right atrium, then to the right ventricle, then to the lungs, then to the left atrium, then the left ventricle. Various valves and vessels also are involved. Routing loops are Bad Things and need to be corrected surgically. The control plane is more like HSRP. The primary biological pacemaker, or HSRP primary, is in the sinoatrial (SA) node, with a basic beat frequency of 75. The signal then should go to the atrioventricular (AV) node, which has a watchdog timer and the ability to act as a pacemaker with a basic frequency of 60. If the AV node doesn't hear an SA trigger in a certain period, it becomes the active pacemaker. Similarly, the ventricles also have backup pacing ability at a rate of about 25. I have a problem between the SA and AV nodes, and my electronic pacemaker fires off when it doesn't see the pulse that it thinks it should, giving me a normal rate of 95. The pacemaker is smart enough to sense physical activity and turn up the rate if I'm exercising. The series of backups doesn't always work correctly. Ventricular fibrillation, beloved of ER shows, is essentially a condition where random parts of the ventricles act as their own pacemakers. It's like a bunch of input interfaces kind of randomly throwing packets around without even aiming at the right output interface. A cardiac catheterization/angiogram is something like a debug, in that the probe may block vessels while doing its measurements. Stress tests, which may be done with exercise (treadmills or bicycles) or with stimulating drugs, are more like extended pings for performance. There's actually a very nice page at the NIH Clinical Center, where I am followed on a research basis: http://rover.nhlbi.nih.gov/labs/7east/cardtests.htm are the veins leading to and from the heart like Fibre cables...(heavily sheilded) any advise on this matter would be most helpfull as he is starting to leek and scream out in pain...

RE: Does MPLS really live up to all its hype? [7:6151]
Actually, Cisco bought the ONS 15900 along with Monterey Networks for 500 million in August of 1999. That's what makes this a particularly interesting move by Cisco since this was an aquisition which places them in the market of one of the next big core technologies exactly following the corporate culture NRF mentioned. Core network technologies has always been their bread and butter and to see them dump the Monterey project after investing and aquiring the company just because of the economic slow down is questionable in my mind. Other companies have had it rough too. I've heard Lucent almost went bankrupt but as NRF pointed out they are still heavily investing in Lambda switching. It has been confirmed by the VP of Optical Networking that Cisco doesn't plan on reengaging the lambda switching market anytime soon. With a compound annual growth rate of 137% and an estimated 5.7 billion spent in optical switches by 2005 the question in my mind is...Is this an irresponsible move by a leader in the networking industry? Much as I like Nortel, the True Leader is Mary. Mary had a little lambda... Shari Lewis and Lamdachop also presumably demonstrated optical access control.

RE: Does MPLS really live up to all its hype? [7:6151]
I don't think so, there really isn't a market for lambda routers at the moment (I think Lucent just sold its first Lambda Router, after over a year since the announcement). The money is still in selling T1's T3's, thus the demand is for edge products that groom T1/T3 into optical trunks. There just isn't much demand for products that switch wavelengths as there are minimal applications for the services those devices provide. Wavelength switches may take off in a few years, but the short term outlook isn't pretty. IMHO, Cisco decided to cut its losses on Monterey and keep its options open for the future, rather than continuing to sink money into a struggling technology.

That's what makes this a particularly interesting move by Cisco since this was an aquisition which places them in the market of one of the next big core technologies exactly following the corporate culture NRF mentioned. Core network technologies has always been their bread and butter and to see them dump the Monterey project after investing and aquiring the company just because of the economic slow down is questionable in my mind. Other companies have had it rough too. I've heard Lucent almost went bankrupt but as NRF pointed out they are still heavily investing in Lambda switching. It has been confirmed by the VP of Optical Networking that Cisco doesn't plan on reengaging the lambda switching market anytime soon. With a compound annual growth rate of 137% and an estimated 5.7 billion spent in optical switches by 2005 the question in my mind is...Is this an irresponsible move by a leader in the networking industry? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of NRF Sent: Tuesday, May 29, 2001 10:08 PM To: [EMAIL PROTECTED] Subject: Re: Does MPLS really live up to all its hype? [7:6151] KY wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Mike, I agree with you. cisco definitely made a fatal mistake here and leave a huge room for at least one company, Juniper. Well, I'm sure that everybody knows Cisco's corporate strategy has always been to try to figure out what's going to be hot, and then just acquire somebody. Sometimes it works (Grand Junction still being the best example), sometimes it doesn't. But I've never seen Cisco as much of a research-oriented company, at least not in the lines of Lucent, with its world-class Bell Labs, or Nortel. Rather, it is a sales/marketing driven company that also likes to play the acquisition card. So I'm sure that if and when lambda switching really gets big, Cisco will come calling, wallet in hand. The suits in Cisco must be thinking something like: This acquisition strategy has worked pretty well so far, so why not keep doing it? Of course, this strategy is not so easy to do when your stock price has crashed. Cisco better figure out how to get its market cap back up. Note - for would-be flamers - I am not commenting on whether Cisco's dumping of the 15900 was a smart or stupid thing. What I am saying is that doing so was perfectly in line with its corporate culture. And I'm sure we would all agree that it is extremely difficult for big companies to change their culture.

We tend to think that a small network could not be better served by applying the same principles that we might use for a larger environment. Why is that? Instead of letting the number of devices determine the right solution (Or more properly, a good solution), let's form a solution based on the specific requirements. A network with a small number of devices, but consisting of multiple sites, and redundant links, presents a unique challenge. Forget the number of devices, and look at both the physical topology, and the problem that needs solving. BGPs powerful policy routing tools make it a good fit for this environment, when viewed from a requirements perspective. I think BGP is completely unecessary in this case.YES, splitting it into two ASes ans using eBGP would work (well), but i really think that modifying the path cost would be the right solution. remember that i never said eBGP wouldnt work. the initial discussion was about using BGP to do this in a SINGLE AS. ...don't get all in a tizzy, i recognize that you have a good idea.

After hearing a better explanation of the real issue, path selection for an International site, the use of BGP might go a long way toward solving the issue. He could very simply address his issues by breaking his OSPF into two seperate routing domains, and utilizing BGP as a means of interconnecting them. He could manipulate the traffic through the use of something as simple as AS-path prepending, or the other mechanisms Chuck mentioned (local preference, weight, or meds). Routing protocols are but tools, a simple means to an end. Like all tools, each has it's strengths and weaknesses. Most important is that you select the right one for a given situation.

Well, I'm not sure exactly what you are asking, but both having done some biomedical engineering and also having been through angioplasties, bypass, pacemakers, and various research procedures... Is it like BGP or OSPF routing when trying to track a blood clott... left ventricle first..unless there is a weight on the right... No, it's more like static routing. There is also separation of the control and forwarding planes. In the forwarding plane, venous blood (veins flow to the heart, arteries flow from the heart), enters the right atrium, then to the right ventricle, then to the lungs, then to the left atrium, then the left ventricle. Various valves and vessels also are involved. Routing loops are Bad Things and need to be corrected surgically. The control plane is more like HSRP. The primary biological pacemaker, or HSRP primary, is in the sinoatrial (SA) node, with a basic beat frequency of 75. The signal then should go to the atrioventricular (AV) node, which has a watchdog timer and the ability to act as a pacemaker with a basic frequency of 60. If the AV node doesn't hear an SA trigger in a certain period, it becomes the active pacemaker. Similarly, the ventricles also have backup pacing ability at a rate of about 25. I have a problem between the SA and AV nodes, and my electronic pacemaker fires off when it doesn't see the pulse that it thinks it should, giving me a normal rate of 95. The pacemaker is smart enough to sense physical activity and turn up the rate if I'm exercising. The series of backups doesn't always work correctly. Ventricular fibrillation, beloved of ER shows, is essentially a condition where random parts of the ventricles act as their own pacemakers. It's like a bunch of input interfaces kind of randomly throwing packets around without even aiming at the right output interface. A cardiac catheterization/angiogram is something like a debug, in that the probe may block vessels while doing its measurements. Stress tests, which may be done with exercise (treadmills or bicycles) or with stimulating drugs, are more like extended pings for performance. There's actually a very nice page at the NIH Clinical Center, where I am followed on a research basis: http://rover.nhlbi.nih.gov/labs/7east/cardtests.htm are the veins leading to and from the heart like Fibre cables...(heavily sheilded) any advise on this matter would be most helpfull as he is starting to leek and scream out in pain...

The specs on the 4500-M are as follows: - 4mb of flash - 32mb of system memory - 1 4pt serial module (NP-4T) - 1 8pt bri module (NP-8B) - 1 6pt ethernet module (NP-6E) Please let me know if you are interested in the whole box or just the modules. __ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=6464t=6464 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: elementary? [7:6359]
Chuck, It's pretty much an issue of semantics... Another station could send to you, but the frame would be buffered by the switch until the current frame had finished sending. It would be transmitted to you afterward. Also, to confirm Peter's statement that he's never seen a full-duplex hub... Such an animal does not/can not exist. This is one of the key differences between hubs and switches. A hub, by it's very nature, cannot provide full-duplex operation. It has no means of bufferring frames, nor of providing segmentation on a per node basis. A hub is layer 1 device, and the network is provides is a shared medium. Vijay, chances are that if it has a 1Gbps uplink, it is a switch, and depending on the number of connected 100Mbps stations, and your network traffic patterns, you very well might be able to saturate the uplink connection, because a switch allows for multiple simultaneous conversations. Under the right conditions, you could fill up virtually any pipe, but unless your traffic demands are really outlandish, you probably won't. If you do, you should examine the reasons, and revise the design of your network accordingly.

Is there any point at which this 1Gb uplink can become saturated, since it's only handling station to station sessions- one at a time. If a number of stations on each switch were doing large file transfers to each other via the uplink, would there be some point at which the uplink would be maxed out- in terms of bandwidth? Or is the only limiting factor, the workstations inability to pump data out fast enough to max out the uplink when they're only running 100Mb?

inside
each OSPF area, however, OSPF routers (at least in my understanding and
most
Cisco Press book diagrams) are either totally inside an area (all
interfaces
inside a single Area, although they may connect elsewhere using other
routing protocols, we're only considering OSPF) or sit on the edge of
multiple areas (ABRs). Having said that, I would think the problem now
becomes one like this: (please excuse my ASCII drawing skills =)
| Area 0 | | Area 1 | | Area 2 |
| R1 R2 |
| ___| || |___|
The Virtual Link is now between R2 and R1. In this new scenario, there
is
no issue about where the traffic destined for Area 1 goes (it goes to R1).
Can you further explain the scenario you speak of with 3 OSPF Areas with a
router in each Area?That sounds more like a BGP thing where a router
is
inside an AS but can connect to routers in other ASes (via eBGP) without
being part of the other AS.

Ever wonder what the CCIE candidates talk about on the CCIE list?
The following message came through today. I thought the bright folks on
this
list might be curious, and might want to venture an answer.
Begin original question:
Guys,
I wonder if there is anybody who remembers the discussion on Virtual
Links in OSPF. It was posted some time ago but I can't seem to find it.
The scenario was something like this:
___ ___
|Area 0 | |Area1||Area2|
|R0|--| R1 |--| R2 |
|__| |_||_|
There is a virtual link from area 2 to Area 0 via Area1. Traffic needs
to
get to R1 in Area 1 from R2 in Area 2. Assume that the virtual link has
to
use R1 (To create the V.Link). Does the traffic flow passed R1 (in Area
1)
to Area 0 and then back to area 1, or does the actual flow just to R1
from
R2.
I cant remember the conclusion, and I cant seem to find it on the
archives.
Quite interesting issues.
End of original question
Chuck
One IOS to forward them all.
One IOS to find them.
One IOS to summarize them all
And in the routing table bind them.

Re: elementary? [7:6359]
I think everybody might be right here but arguing about different parts of the process, or confusing the meaning of the previous post , so just to add more confusion: Peter said that all every station could send as much as they want, which I think he was referring to their own ethernet segment/(switch port). On the Gig link, buffering will obviously have to take place. Statistical multiplexing seems a good summary of what's happening. I'm not sure exactly what you were saying in the last post Alan, about the buffering. Full duplex operation will allow another station to send to you while you are sending to it, so no buffering required in that case. As usual, open (prone) to correction, Gaz W. Alan Robertson wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Chuck, It's pretty much an issue of semantics... Another station could send to you, but the frame would be buffered by the switch until the current frame had finished sending. It would be transmitted to you afterward. Also, to confirm Peter's statement that he's never seen a full-duplex hub... Such an animal does not/can not exist. This is one of the key differences between hubs and switches. A hub, by it's very nature, cannot provide full-duplex operation. It has no means of bufferring frames, nor of providing segmentation on a per node basis. A hub is layer 1 device, and the network is provides is a shared medium. Vijay, chances are that if it has a 1Gbps uplink, it is a switch, and depending on the number of connected 100Mbps stations, and your network traffic patterns, you very well might be able to saturate the uplink connection, because a switch allows for multiple simultaneous conversations. Under the right conditions, you could fill up virtually any pipe, but unless your traffic demands are really outlandish, you probably won't. If you do, you should examine the reasons, and revise the design of your network accordingly.

With full duplex, you have effectively created two directions --- there and back. I believe it is accurate to say that only one packet can be on the wire per direction at one time. I can send to you at the same time you are sending to me. But Someone else can not send to you at the time my packet is on the wire. Correct me if I'm wrong.

[7:6359] N. nononononono. CSMA/CD only gets used when you are not in full duplex. (/me ducks) ( i have NEVER seen a full-dup. hub) meaning that if i am using a switch capable of full duplex (as most are) ..conversations, every station can transmit as much as they want. this is what differentiates between a hub and a switch. (but not the only thing) you are correct in that a 100 meg HUB with a gig uplink could never fully utilize the link, but the case is completly different with a switch. - Original Message - From: Vijay Ramcharan To: Sent: Wednesday, May 30, 2001 9:54 AM Subject: RE: elementary? [7:6359] Thanks everyone for their replies. As I now understand it, the 1Gb uplink just moves data faster than... say, a 100Mb uplink. Correct? Conversations between hosts on each switch still take place one at a time, thereby obeying Ethernet rules of one station transmitting at a time. Correct? Okay my next question. Is there any point at which this 1Gb uplink can become saturated, since it's only handling station to station sessions- one at a time. If a number of stations on each switch were doing large file transfers to each other via the uplink, would there be some point at which the uplink would be maxed out- in terms of bandwidth? Or is the only limiting factor, the workstations inability to pump data out fast enough to max out the uplink when they're only running 100Mb? I'm thinking that it's really not possible to max out a 1Gb uplink when stations are only running 100Mb. If this is correct then I lay this question to rest. Thanks.

[7:6359] Forgive me if this sounds a little bit basic but this is what happens when you rush into things without understanding the fundamentals. Suppose a 24 port 100Mbit switch called A is uplinked to another 24 port 100Mb switch called B via a 1Gb connnection. Suppose hosts D through N are on switch

How about because unlike MSCE, Cisco certifications actually teach you about networking?

question regarding spanning tree [7:6485]
Hello. I don't really have a problem so much as I am trying to get a better understanding of how Spanning Tree works. I am currently studying for my switching exam and am reviewing Spanning Tree. I have the following statement from the Cisco course manual and in the case of redundant paths to the root bridge, it states In order to choose which port will be forwarding data and which ports will be blocking data, the switch looks at two components in the BPDU, as follows: 1. Path Cost 2. Port ID The switch looks at the path cost first to determine which port is receiving the lowest cost path. If the path cost is equal, as in the case of parallel links, the bridge goes to the port ID as a tie-breaker. The port with the lowest port ID forwards and all other ports block. I decided to verify this on one of my 4006's which connects to my 6509 (which is the root) and here is what I found: pet4006_8 (enable) sh spantree statistics 1/2 1 Port 1/2 VLAN 1 SpanningTree enabled for vlanNo = 1 BPDU-related parameters port spanning tree enabled stateforwarding port_id 0x8002 port number 0x2 path cost4 message age (port/VLAN) 0(20) designated_root 00-d0-01-98-5c-00 designated_cost 0 designated_bridge00-d0-01-98-5c-00 designated_port 0x8087 top_change_ack FALSE config_pending FALSE port_inconsistency none PORT based information statistics config bpdu's xmitted (port/VLAN)0(8702816) config bpdu's received (port/VLAN) 831061(1662121) tcn bpdu's xmitted (port/VLAN) 1(1) pet4006_8 (enable) sh spantree statistics 1/1 1 Port 1/1 VLAN 1 SpanningTree enabled for vlanNo = 1 BPDU-related parameters port spanning tree enabled stateblocking port_id 0x8001 port number 0x1 path cost4 message age (port/VLAN) 1(20) designated_root 00-d0-01-98-5c-00 designated_cost 0 designated_bridge00-d0-01-98-5c-00 designated_port 0x80c8 top_change_ack FALSE config_pending FALSE port_inconsistency none However, as you can see from the above output, Port 1/2 is the port chosen to forward and it appears to have a higher port ID number. Can someone please explain what I am missing here? Thanks!
