BLIMEY !!! this is getting a little heated L+G`s . i personally believe that when i got my CCNA if i had been asked to configure BGP (even Basic) on an internet connecting router for a small-medium sized company...i would have run away screaming...

Re: Help with huge amount of Input/Frame and some CRC errors [7:21657]
symon... sorryi am asleep i don`t like the amount of interface resets you are getting... can you clear counters and watch the amount you are gettingon both sides.. int resets cum from the line bieng dropped (g703/line) i have smds/leased lines and you should not get ANY int resets on a good line. the last time i had this problem it was the BT CSU/DSU that was at fault that FUNNY you know ...al the BT CSU/DSU (for there 2 meg leased) have an X21 port built in you could also try swapping the ints (S0-S1)on both sides to see if that makes a difference... Is this a new install?? it IS possible that the G703 converter is stuffedwe use BlackBox ones...and they SHOULD work straight out of the box...

Re: Dual FIFO? [7:19691]
the only thing i could find was this http://www.cisco.com/warp/public/788/voice-qos/voip-ov-fr-qos.pdf which says "Turn on fragmentation for low speed links (less than 1.5Mbps). Set the fragment size so voice packets are not fragmented and do not experience a serialization delay greater than 20 ms. Lowest Link Speed in Path Recommended Fragmentation Size 56Kbps 70 bytes 64Kbps 80 bytes 128Kbps 160 bytes 256Kbps 320 bytes 512Kbps 640 bytes 768Kbps 1000 bytes 1536Kbps 1600 bytes Note: For 1536 Kbps, no fragmentation is technically needed, but fragmentation is needed to enable the dual first-in, first-out (FIFO) queueing system to ensure voice quality. A fragment size of 1600 bytes enables the dual FIFO, but since 1600 bytes is higher than the typical serial interface maximum transmission unit (MTU), large data packets are not fragmented. from what it says it`s just multple "stack" queue sorry i can`t be of more help..

Hi, sorry i missed this ,but i wanted to comment anyway. i have had the same situ recently working on a project in the UK. we also used static routes/dialer commands simply because of this . we had a spate of recent laptop/desktop theft`s and people were trying to get to our network after stealing these boxes. now that we have changed it so that once you call and try to authentciate we simply set our boxes to dial back a fixed number and use a fixed ip address ... it`s sounds like overkill ...but it`s the only way to be sure...

RE: Figuring out Config Register Values [7:15894]
on the subject ...
another good search engine is the cisco/google engine
http://cisco.google.com/cisco
i have found this very helpfull in "pointing me in the right direction"..
it will usually find a page that is in the general topic and i can search
around from there to find what i really want...
someone on the list passed this on to me some time ago .( nice chap
...forgot his name).
Sherlock Holmes (Sir Arthur Conen Doyle) once said ."the more sorces of
information one has the quicker the truth will present itself"...

Re: Question about fast switching and layer 3 switching [7:13962]
Hi, what you said is almost correct ... Proccess/Fast/Distributed/Packet switching are all layer 2 functions.. >From the CCO Fast switching allows higher throughput by switching a packet using a cache created by the initial packet sent to a particular destination. "this is all done at layer 2" Destination addresses are stored in the high-speed (switching)cache to expedite forwarding. Routers offer better packet-transfer performance when fast switching is enabled. Fast switching is enabled by default on all interfaces that support fast switching. layer 3 switching differs from this by having the first packet sent to the router (which routes the packet to the correct outgoing port ..this is a more efficent way of finding destinations than switching ,...switching envolves looking at a singular table or flooding -leaveing out CEF on purpose-) it then stores this info in the cache and all following/Same destination packets are switched using info in the cache... i have read somewhere that is 4-9 times faster to switch a packet than to route one so this gives us an increase in throughput via "intelligent switching"-my own term please don`t quote me on the 4-9 times bit ...but it IS defenatly faster to switch ..

Hi, The Source-Quench message comes from a server when it`s buffers are unable to process all the info bieng sent to it.. this usually means that the nt is set for 100/Full - the switch is set for 100/full for the nt box , but the UX box (and its switch port)is only set for 10/half ...usually the switch is aet to auto . without any special processing on the switch it will just send as many packets out of one port that it recieve`s from another... check the settings on both servers and make sure there the same... then try agian ... happens to me all the time.and the server guys INsist it`s the network HTH steve >From: "Amit Gupta" >Reply-To: "Amit Gupta" >To: [EMAIL PROTECTED] >Subject: Source Quench [7:12477] >Date: Mon, 16 Jul 2001 10:29:14 -0400 > >Hi All, > >I am getting a " Source Quench message " from one of >my HP-UX Servers when I try to ping it from an NT >machine / Switch > >I am getting the following msg when I ping the server >from the external router >Sending 5, 100-byte ICMP Echos to x.x.x.x timeout is 2 >seconds: >Q > >However if I ping the same server from a Unix machine >/ server, it is ok. > >Could it be a problem with the server NIC > >Thanks & Regards > >Amit > > > > > > > >__ >Do You Yahoo!? >Get personalized email addresses from Yahoo!

RE: EIGRP and IGRP network discovery [7:11273]
OK, i am going out on a limb here ,but i am going to try and answer the questionor atleast redefine it.. the originall question was "how does E-IGRP discover networks" well first what do we mean by networks. "networks are just routers with configured ports" ... i suppose so... we could say of networks...that the router discovers networks by the use of the neibghour discovery proccess WHY.we`ll the only way a router can find out about different networks is from other routers.or neighbours.. so it will get networks info from the update it recieves form other routers... from the white paper "To distribute routing information throughout a network, EIGRP uses non-periodic incremental routing updates. That is, EIGRP only sends routing updates about paths that have changed when those paths change. " this would explain WHAT happens but HOW...or more precisely..what does iti have been unable to find out...

Re: Cisco 5505 switch puzzle [7:11335]
goof. the problem i am trying to indicate (badly) is this .when the cisco switch process`s the command "vtp rev 0" (yeah,i know that no the command.but hey)...the logical order of proccessing in the IOS(not your config) is to check the config/memory for any vlan info if the switch comes across this info it makes a change to what it calls the "active vlan`s" and updates it`s rev number "as of catos 4.5.1" the only way to have a rev number of 0 stay 0 is to not have any vlan info on it or not activate vtp ...as is told on the BSCN course if you don`t want to have your new/additional switch add/overrite your vlan`s ,clear the vlan info and set it to transparent i don`t have a 55/65 handy but if anyone does please try it (unless ofcourse they have changed the ios again) this was all passed onto my by a TAC SE in cisco before he was saked Hm...i may well be wrong then steve...politely discussing.and NOT arguing >From: "Gareth Hinton" >Reply-To: "Gareth Hinton" >To: [EMAIL PROTECTED] >Subject: Re: Cisco 5505 switch puzzle [7:11335] >Date: Mon, 9 Jul 2001 13:19:02 -0400 > >Just for arguments sake I'm going to argue.

hi, YES ,this is a stupid question (I`M ONLY KIDDING)...the only stupid question is one you don`t ask,,, the Cisco boxes run IOS " internetworking operating system" ,this is based around unix( it`s has to be very effcient,small and robust windows i`m afraid ,just won`t cut the mustard. it is not "compatible" with any operationg systems..as such ,but it understands TCP/IP,IPX,NETbeui,appletalk,NBT.. so it can work with most device`s ( in a moving information capacity from one pc to another local/Remote pc (switching) and making intelligent (???) decisions as to how to get one piece of info from one place to another (routing) OR bieng told how to do this manually by humans(static routing) ... the ios is command line only( sort ofyou can by GUI packages that will help you configure them i.e Cisco config maker (good for low end devices) and CNS good for most devices) but i would say that it is command line ONLY because you`ll be spending most of your time there anyway...we all do.. most boxes run either a motorolo 68X00series chip or nowadays the risc power pc chips and have NVram as storage ...

Re: Cisco 5505 switch puzzle [7:11335]
chaps, what is happeneing is a loop. when you config in a VTP rev of 0 ,the processing of this command causes a fresh lookup of all vlan info relevant to vlan`s in the routers memeory... ( PLEASE don`t pick to many pieces in this ...i just outlining the problem ,and have a VERY shakey recolection of bieng told this once...also it`s the way the cisco ios proccesess commands) seeing vlan info in the memeory/config it recognises this as a change and updates the VTP rev..(if in server mode) causing a change to be sent to your server switch s2 overwriting it`s config ,causing a rev update ,causing an update to be sent to s1 and thus casuing the great VTP "chain of life". the first answer you recieved forkmk nigel is right "again as far as i can remeber"..

Re: Is EIGRP a DV or LS protocol [7:10657]
A... that old debate ( i am waiting for howard to comment ) but as far as your answer is consernced ..it`s distance vector HYBRID a lot of the instructor`s i know read it like this . EIGRP is based on IGRP ...so it`s distance vector... EIGRP behave`s like a link state protocol ..so it`s link state EIGRP is cisco`s own ...uses the best of both world`s ...so it`s a HYBRID and should really have it`s own clssification BUT according to the designer`s (i`m told) it IS a distance vector protocol..With extensions in the exam`s (lets keep this relevant to why were here ..and no i don`t mean on the planet just the list)...it will be classified on the exam as distance vector...

Guys, lets see how my ospf is going .. in this design goal i would have thought you would have done this hub and spokeat the hub you have say 1 router (3620) with one interface and 20 sub-interfaces... you also have 20 totally stubby area`s which connect into the hub... config each stub as area 1 through 20 setup each sub int as per area`s 1-20 then setup the lan int as area 0 this way you have one router (hub) which is in area 0 and all the other area`s aswell problem solved .. something tells me i`ve just either A got it right and am a genius B completely missed the point and broken every rule of ospf YOU DECIDE steve >From: "Chuck Larrieu" >Reply-To: "Chuck Larrieu" >To: [EMAIL PROTECTED] >Subject: RE: OSPF Hub and Spoke [7:9268] >Date: Fri, 22 Jun 2001 01:15:31 -0400 > >John, this one's got me to thinking a little bit.

Re: Gre tunnel - ip and ipx packet loss -URGENT!!!!!!!! [7:8212]
deferred ..as far as i can remember that means either one of two things you interface is not working properly (joke)... the packets are defered because thet cannot be put onto the output buffer of the interface (sort-of)this has meant to me in the past either corrupt memeory/ios or a not enough memory.in one extreme case it also meant swapping the memory in one of my 36`s check your buffers (I should coco) and see if your getting any "misses" and also any "failures" if you are getting them on anything quite high (this can depend on how long the routers have been up to how many logged errors your getting) apart from your middle buffers (normal) you may be going in the right direction...me thinks HTH steve >From: "John Kale" >Reply-To: "John Kale" >To: [EMAIL PROTECTED] >Subject: Gre tunnel - ip and ipx packet loss -URGENT [7:8190] >Date: Tue, 12 Jun 2001 12:14:43 -0400 > >hi all, >We run a gre tunnel between sites across an isp network...sometimes we lose >connectivity (ipx mainly and somtimes both IP & IPX) but the show tunnel >and >show interface commands gives an up, up status. > >The only thing unusual is that the show int f0/0 commands reveals a rising >number of packets deferred. what does the ' deferred' signify and >can anybody pls come up with tips on making this tunnel a trouble free one. > >regards, > > >John >_ >Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: OSPF scenario [7:7605]

Re: Layer3 switch vs Router [7:7406]
Jason, the real answer to your questions is this. first why do we use layer 3 devices.. well MAINLY for intervlan routing,,,we are all agreed...yes then , we migh have these two different setup`s. a 6500 with an internal MSFC on a sup 2G... and a 6500 with an external router ...a 3620..with GBIC and 32 meg if ram(base spec) AGGREED the only real difference is.latency...and space YES i know the specs don`t equate BUT i am answering his question... in a perfect world both setup`s would be identical ...if that was the case then 1. you need more space having 2 seperate devices... 2. you will suffer from a slight speed differnce with the msfc sending info over the cat`s inbuilt backplane..3 gig and you sending info over the 1 gig link form switch to external router...this is ALL... forget packets/bytes/bits per secondthis is where your speed in/decreases are seen . SO if your asking this question because managment want to know WHY they should by a 6500 and msfc . i hope that answers your question. steve( i`ve been more char-grilled.(because of this responce) than a BK Flamer) >From: "Denton, Jason" >Reply-To: "Denton, Jason" >To: [EMAIL PROTECTED] >Subject: Layer3 switch vs Router [7:7406] >Date: Wed, 6 Jun 2001 15:35:16 -0400 > >Can anyone tell me what the REAL difference is between a layer3 switch and >a >router? > >Jason _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Howdy answer 1..Do it properly.(if have the money)... i have always recommnded duplicate everything down to the ios image for redundency(get another 6509 and run HSRP on it) answer 2we can`t afford a proper network .(make sure when the backup kicks in .that you are not responsible for the SLOW network.i.e you told them so) i would do this get a 4006 not a expensive as a 6509 but SHOULD do the job ...setup with slightly higher spantre prioity ...will feed of 65 and should take over quite quickly next buy a seperate 2600 and runn HSRP over the ethernet link between them .(REMEBER we are talking Redundency)... you could put a second E card in the 26 but you would not be able to "call"... it redundent...and besides YOU willl take the rap if the company hits the wall.(let me tell you a story) once apon a time there was a man who was given a spec to build a network with full redundency...the spec he put togother cost WAY to much and need severly cutting down...he told them not to do it but they ordered him to .so he did it the network fell over and the company sued for designing a crap network ...who got the blame..the man with his NAME on the design doc. have fun steve >From: "David Cooper" >Reply-To: "David Cooper" >To: [EMAIL PROTECTED] >Subject: backup plan for a campus [7:7052] >Date: Mon, 4 Jun 2001 08:31:21 -0400 > >hiya folks :) happy monday > >I'm thinking of backup solutions for a network I'm consulting for. >This network consists of 7 Vlans of which 5 are used for production.

Re: Redundancy design question [7:6646]
Jon, the answer to your question is NO. here`s the reasonyou COULD make yourself a Y cable from your CSU/DSU ,but you would have a few issues. I tried this sometime ago and found out the hard way. OK.first thing if both routers are on you have a major routing loop problem..AKA split horizon/Spanning tree both routers would recieve the input packet from the CSU and both would try to route it at the same time...(VERY BAD)i totally screwed up my lab routing by doing this . Also packets from host to internet are not routed properly... So i tried HSRP but found that only worked if i had only one VLan and didn`t load balance.it also was not as fast as just having one router..( pass as to why) SO you could set-up the cable and say shutdown one int on the backup router...which still means you have a latency (until you re-enablen the int and re-convergence takes place). i hope this is helpfull... BTW Please don`t ask me about CSU/DSU clocking as it was a BT leased line CSU/DSU and all i did was rip the cable apart and duplicate it ...

RE: Weird DHCP/VLAN solution suggestions wanted!! [7:6579]
Guys, there is something very WRONG here i have a 6509 on site a single DHCP server ..various VLans and never miss an renew are you using the ip helper address properly...( i Mean NO offence)...what i mean is setting a range ip helper address 10.0.*.* to 193.194.199.9 if so check the lease`s on the DHCP server... i need some more info to help i recon your DHCP server is up the swanyare there enough addresses in the scope for all users... (someone i know set up a scope with 1 ip address in to and wondered why only one client got a renew) you only need the ip dhcp command if you want to 65 to BECOME the Dhcp server...(don`t do it it`s a nightmare to adiminster)... please post MSFC configs for inspection HTH steve >From: "Chuck Larrieu" >Reply-To: "Chuck Larrieu" >To: [EMAIL PROTECTED] >Subject: RE: Weird DHCP/VLAN solution suggestions wanted!!

O.T : Heart By-pass Surgery...Anyone got any links???? [7:6408]
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. 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... 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...
