Router throughput
After further thought and having been a little short, I thought I'd add something to my previous offering. I specifically remember two very odd questions on the CCIE written (roughly) about this subject, no kiddin'. Throughput=Switching Time+(Packet SizexTime per Byte) Look at this formula a little more closely. It says, for one thing, that the time normally needed to switch a packet is a constant, made up of factors like interrupt frequency, header processing, routing table lookup time needed, and so on. Also, the throughput formula claims that there is a component to throughput that is proportional to packet size and that represents the time needed to copy a packet before translating it. Using this formula can be of some help in comparing routers whose vendors use differing yardsticks in measuring their products' performance. Another way of making sense of such comparisons is to obtain throughput statistics for different- size packets, perhaps of a minimum, middle, and maximum size. Or you could look for two different statistics--switching speed given in packets per second and throughput represented as bytes per second. r/ rainman "Howard C.

Re: 2505 routers
They're just hub ports, with an internal controller BUT, if you want to pass traffic to another segment or if you want to employ other "routing" functions, i.e. ACL's, Policy Routing destinations, caching tweaks, etc. then the hub connected devices are the segment/broadcast domain those routing functions would target. In other words, you're routing TO the devices connected to the hub through the E0 virtual interface. FTP is one of the TCP/IP applications and TFTP is another =8^) c'mon mister mcse, you knew that! you're testing us, right? =8^) but seriously, if you want the NT box to run the TFTP daemon (listening service) all you need to do is put one on there and configure it.

Re: Router CPU power
Howeird is completely correct. Sure enough, you can get cpu processor speeds from the gear fact sheet, but this is a poor indicator of how the box is going to perform under load. There are simply too many factors effecting actual throughput to use this metric for anything except a stripped-down router. This is why routers, switches, etc. are rated on PPS. r/ rainman "Howard C.

Re: Access List Question
I'm sorry Mohamed, I have to disagree that this is not possible with Cisco IOS. All of the advice I've seen so far is true to Standard & Extended ACL's. BUT, with Named Access Lists (=/> IOS 11.2) you can dynamically change the list, but you must disable the ACL wherever it's applied, and re-enable it after the change (personal experience). Named Access List Example The following configuration creates a standard access list named Internet_filter and an extended access list named marketing_group: interface Ethernet 1 ip address 2.0.5.1 255.255.255.0 ip access-group Internet_filter out ip access-group marketing_group in ... ip access-list standard Internet_filter permit 1.2.3.4 deny any ip access-list extended marketing_group permit tcp any 171.69.0.0 0.0.255.255 eq telnet deny tcp any any permit icmp any any deny udp any 171.69.0.0 0.0.255.255 lt 1024 deny ip any any log ...

Re: Spanning Tree
h A Root Bridge election is one function: determine which bridge in a collection of bridges on a LAN and for multiple inter-connected LANS will be the Root... The Designated Bridge election has another, different function: determine which bridge, as you noted, has the least cost path TO the Root Bridge. This notion of having a designated bridge precludes the possibility of having simultaneously active bridges that are acting in parallel to each other between two LANs. Each election process is triggered anew with topology deltas, of course, which is why the STA is a dynamic algorithm. Does this explanation respond to both of your questions? =8^) R/ Rainman "Deloso, Elmer G." wrote: Hi, all.

Re: Static Routing or Route Maps
Pardon my interruption Lekan I *believe* there may be one consideration missing from your advice. If I am wrong, please forgive me. Floating statics which point to a next hop address are, of course, hard-coded routes in your IGP table... no matter if the metric for a secondary or backup route has a larger AD the one with the smaller AD is hard-coded in the route table; if it goes down, there's no way for the route table to know it. What I have done to overcome this is to use the interface itself as the next hop, e.g.: 0.0.0.0 0.0.0.0 Serial0/0.1 0.0.0.0 0.0.0.0 Serial0/0.2 200 ... but, truth be known, I do not have a very granular explanation why this configuration is able to dynamically perform routing table maintenance.

Re: Can you block CDP with an access list???
again. read up udp=layer 4 cdp=NOT layer 4 in fatto: cdp is cisco's implementation of stretching layer 2 rules. The Cisco Discovery Protocol (CDP) Discovery Protocol CDP allows devices to share basic configuration information without even configuring any protocol specific information. CDP is enabled by default on all interfaces. CDP is a Datalink Protocol occuring at Layer 2 of the OSI model. This is important to understand because CDP is not routable. It can only traverse to directly connected devices. CDP allows you to view information such Operating System Version, Protocol Information, and much more. This can be very handy for troubleshooting a variety of problems. Aaron Prather wrote: > If you can what protocol does it use?

Re: ISDN Configuration - Help
Aziz, Light! (Sorry, it's from "The Fifth Element" and I couldn't help it) First, the easy one: If you don't want RouterB to be able to dial to RouterA, simply do not define interesting traffic (am I missing something?) Second (the linear thinker in me) (Assuming Q.931 & Q.921 are cool) Remove auth. altogether; does the int complete the call? Next (progressive jazz): Eliminate "Ppp pap sent-username RouterB password cisco2" from the BRI0 interface on RouterB; with debug dialer & debug ppp neg, what's going on? (btw: doophus question of the day: what's "debug ppp auth" ? I think your passwords are bass-ackwards. On RouterB, I think you wanna put "Ppp pap sent-username RouterA password cisco1" and vice-versa on RouterA. Remember the words of the venerable Bruce Caslow "It's always TWO things; (1) What to do; and (2) What to look for" Please let me know if this works 'cause I can't call out to another ISDN- Connected router (unless you want to work a few things out together!)

Re: ip and subnet
Let me have a whack at this (somewhat ambiguous) scenario 10.150.25.25/16 tries to ping 10.150.100.25/24 (assuming we're traversing a router, right?) 10.150.25.25/16 is trying to ping an address in his same network and the interface has no reason to believe that 10.150.100.25 is NOT in his own broadcast domain or in his own subnet and therefore has no reason to attempt to arp elsewhere for the owner of an address he thinks he owns. How'd I do?

Sample Question Question
I ran across this question some time ago and kept the darned thing because (I *guess*) I still have something to learn about IP ... . just when I was *sure* I had it down cold. Could you lend a fella a hand? Given the IP address of 193.243.12.43 and a subnet mask of 255.255.255.128, what is the subnet address? a.194.243.12.32 b.193.243.0.0 c.194.243.12.43 d.193.243.12.128 e.None of the above. . . . . . . . . . . . . . . . . . . . . . . . . e. None of the above The Subnet Address is found by setting all of the host bits in an address to 0. According to the mask, there are 7 host bits, so applying this rule yields a subnet address of 193.243.12.0. However, closer inspection yields that there is only one subnet bit in this Class C address - therefore, this is an illegal address/mask pair. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
