Modem on Serial port.
We have a client that requires a DDR Analog modem solution, it must be router based but doesn't want to pay a premium. I've done a little research and it seems that a serial port can support an analog modem (using an appropriate cable). I've eyeballed the 805 as the cheapest solution (ie not necessarily the best). Question is: can a modem be connected to just any serial port and can I then use dialing profiles, etc? Or must I get a proper analog modem pool - kinda wasteful, I only need one modem? Key is that it must be router based. I cannot just hang it off the nearest server - something about some bureaucratical policy. -- Kevin L.

Re: Ethernet Trivia
They would both start at the same time. The 100bT interface would be placing bits on the wire faster than the 10bT interface and would complete placing bits on the wire in 1/10 the time. But those bits can't actually move any faster through the copper medium. The copper isn't more conductive (it's still Cat 5(e)) and the speed of light hasn't increased. So the bits that are placed on the wire will move through the wire at exactly the same rate. If the bits for 10bT consume 5 meters of cable megth before the NIC moves the the next bit then a bit for 100bT will be 1/2 meter (.5 meters) before the next bit is placed on the wire. This is just an example, I'm not sure of the exact lengths of the bits on the wire, but the point is that the bits can't move any faster because the speed of electricity through copper is fixed. The difference is that the 100bT card is placing bits on the wire 10x faster than the 10bT card. And 1000bT (gigabit ethernet) places bits on the wire 100x faster than the 10bT card (or each bit would be .05 meters (5 centimeters), given the above example). So, on 100bT the end of the packet (the whole packet) would arrive before the 10bT would be done (in fact depending on the size of the packet 10bT might still be sending the preamble or headers), but the start of the packets (first bit of the preamble) would arrive at the same time.

service nagle
I've implemented service nagle on our routers (most only have a saturated 56K connection) and the performance seems a little better. My question has to do with the fact that Cisco states do not use this with X-Remote and X-Windows. We aren't running any *nix stuff so I'm OK but I was wondering if any one knew what the issues are? What kinda symptons would appear? Thanx Kevin L. KultgenMCSE+I, MCDBA, CCNA, CNX-A, A+, Network+, i-Net+/CIWIRIS Systems Inc, MCSPCalgary, Alberta
Private AS
Everyone knows that the Private IP Address Ranges are: 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 I've just found out (a few days ago) that the Private AS Range is: 64512 to 65535 Much to the chagrin of my predecessor who used a Public AS number (Some HP company) with the 192.168/16 private IP address range, not that there is anything wrong but I like to be consistant. (and who gets stuck with the renumbering of the AS? wasn't all that hard... just time consuming, no downtime allowed) And YES, from what I can tell private AS numbers can be BGP advertised into another AS with the AS information stripped so it looks like your AS is in your providers AS. Of course, as long as your IP network is public Just a tidbit Kevin L.

Re: Easy Brain Teaser (Switching)
That was my first thought but isn't STP supposed to finish after 30 Seconds? Not the several minutes indicated in the problem. I was thinking that the server doesn't appear to be rebooted, sooo I'm thinking it's the ARP table of the Switch If the server was rebooted or had sent out a network comm... (a simple ping) the switch would have realized that the server was now on a new port. But the switch had to wait until the server sent out a comm of some sort (NetBIOS Broadcast, WINS replication, ...whatever...) to update the ARP table I kinda remember something from groupstudy a looonnn time ago (in a galaxy far, far away...) about a failover server that had a similar problem because it had the same MAC address as the original server. When the original went down the failover had to notify the switch that that MAC address was now on a new port h STP..change the port to portfast Lonnie "John Neiberger" [EMAIL PROTECTED] wrote in message 11620111.962895874039.JavaMail.imail@tiptoe">news:11620111.962895874039.JavaMail.imail@tiptoe... Here's an easy one, because I'm nicer than Chuck. :-) Even though it's easy, it's still practical. And for those of you who immediately know the answer, let the less experienced people mull this one over for a bit. You have a Catalyst 5000 with several servers connected and you've decided to rearrange the port assignments. You disconnect one server in particular and move it to another port, then quickly discover that it now has no network connectivity. You attempt to access the network for a couple of minutes to no avail. In supreme frustration, you head to the break room for coffee and donuts. When you come back several minutes later you find that the server now has network connectivity and all is well, no problems. What is the most likely cause of this behavior and what could you have done to remedy the situation immediately? Good luck!

Re: can I ask some CCNA Question..
I agree. I always use ping first, BUT =P The question doesn't describe the environment. In a worse case type senerio you could be testing tcp/ip connectivity through a firewall or router in which upd and icmp are blocked but tcp isn't. Or is that crazy talk? Many firewalls do have UDP and ICMP mostly blocked for protection. And not TCP. I'm inclined to write his off as a learning experience and maybe a trick question Kevin L.

Re: can I ask some CCNA Question..
1)It Takes three Packets to start a TCP session, how many packet are used to close it One AFAIK. With a Reset flag. 2)To enter the setup mode on a router with no configuration you must type? What command? setup 3)How do you list the current IPX server in the network on a cisco router show ipx servers - to get the various sap servers. 4)If u want to bridge a protocol out a routed interface you can use? A IBM spanning tree B)Intergrated routing and bridging C)SRB D)TB E)SR/TLB Integrated routing and bridging. The clue is that it is a routing interface, and you want to bridge through it. 5)Ethernet network can be considered as congested at ..% utilization? Every company has a different standard. I've commonly heard 60% and 75%, one was Cisco's I think it was 75%. 6)Which are true about Full Duplex a)can be used between hubs b)can be used between switches c)can be used between a switch and a router d)can be used among Ethernet station can be used between switches, a switch and router, and Ethernet stations. A hub doesn't use it unless it's a "switching" hub. Kind of a misnomer. 7)Which of the following describe frame filtering a)Examines info about a frame based on user defined offset b)Uses a frame filtering table c)High level administrative control d)Is similar in function to packet filtering in a router dunno, I would problably say d. need more info. 8)An Internal IPX number is required by what servers and protocol a)IPX RIP router b)NLSP capable device c)IPX server d)NSLP server e) all I'd guess E. Haven't done a whole bunch of IPX or NLSP 9)which layer of OSI provide synchronization between address and name database? I believe Cisco defines DNS at the application layer. However I have seen it defined at the session layer. 10)When subnet and addressing is applied in numerical order this is known as? ??? huh? 11)To enable terminal editing, what is the min privilege level? not sure, never had to turn it on (or off), try it for yourself 12)What command to disable CDP broadcast on a specific interface, what commnad ? what mode? conf t ; int e0 ; no cdp enable no cdp run is used to turn it off globally 13) how many segment to setup a TCP connection? 3 - SYN ; SYN/ACK ; ACK 14) how many ip address can be assigned against a particular host using the ip host command not sure, never hit the limit, usually use a DNS Server 15) TCP/IP connectivity can be checked using ? a)ping b)trace c)telnet ping of coure, trace is usually used as a backup to ping, and telnet tests the whole stack. 16)what command to check the periodic update of RIP? Don't remember, never used rip - (show ip rip ?) 17)What is not a valid metric for IGRP a)Bandwidth b)Delay c)Reliabity d)loading loading is not used. Kevin L.

Re: can I ask some CCNA Question..
Tracert usually uses UDP packets (with TTL) instead of "echo request" packets. Maybe it is a trick question. But ping does check for connectivity at the lowest level of the TCP/IP stack. So if IP works, TCP should. 'Cause if you ping you usually can do tracert and telnet. Unless there is an MTU/fragment issue. Kevin L.
