Re: 2500 series e0 fullduplex?
Though not recommended of course, fast ethernet (as noted by Neil) will run in half-duplex mode. This, along with the introduction of an adequate number of 'slam-dancing/moshing' frames will provide a nice collision display (but please turn down your router speaker first, the sounds can be a little unsettling...) responding to --- >100mbps is not ethernet be sure its fast ethernet ,also their is no > >collisions in fast >ethernet ,its colliision free and this is only possible if u have one >way >to send and >one way to recieve data simultaneously :) i am sure u got the idea >secondly in ethernet there are collisions and if there are colliisions > >Can u use one to >send and one way to recieve simultaneously with collisions so if u cant > >the result is >ethernet works in half duplex mode and fast ethernnet works in full >duplex >if u have any thing different than me plz share with us >waiting ur reply >Saif >Neil Schneider wrote: >It is NOT true that ethernet is half and fastethernet is full duplex. >Either 10Mbps or 100Mbps ehternet can be run in half or full duplex mode. >And offhand I don't know if the 2500 AUI port will do full ethernet. > >-- >Neil Schneider >MCT MCSE CCSI CCNP > >"SAIF" <[EMAIL PROTECTED]> wrote in message >[EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > NO ITS ETHERNET PORT AND WORKING HALF DUPLEX ONLY ,U SEE CISCO GIVES >FASTETHERNET PORTS > > SPECIALLY IN THEIR ROUTERS SPECIALLY IN 4XXX SERIES AND U KNOW ETHERNET >WORKS IN HALF > > DUPLEX AND FASTETHERNET WORKS IN FULL DUPLEX SO THE RESULT IS AUI PORT >IS >HALF DUPLEX > > ETHERNET NOT AUTO SENSE AND IF U WANT AUTOSENSE 10/100 BASE T GO TO ANY >OTHER ROUTER > > ,CHECK THE ROUTER;S MANUAL :) > > HOPT IT WILL HELP > > IS IT ? > > > > Turfis wrote: > > > > > Is the Ethernet AUI port on the 2500 series Cisco routers Full Duplex > > > compatible?

RE: A very basic EIGRP metric question
It appears that you may be talking about Advertised distance (the distance of the path to network X from another router's perspective) versus Feasible distance (which in theory is the lowest combination of the aforementioned Advertised distance and the distance between you and the router(s) that advertised the 'Advertised distance'). But I could be completely wrong -- sorry, no refunds. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of JZ Sent: Tuesday, March 06, 2001 12:35 AM To: [EMAIL PROTECTED] Subject: A very basic EIGRP metric question To simplify my question let's assume K2=K3=K4=K5=0, and K1=1. So EIGRP calculate metric to a destination network using the formula Metric = BW. By definition, BW is calculated using the minimum bandwidth link between source and destination. It is NOT a cumulative value. But, in EIGRP operation , "The metric that the router uses in the routing table, and to advertise to other routers, is the sum of the best advertised metric from all neighbors, plus the link cost to the best neighbor." base on this, the metric to a destination network would be the sum of the BWs in the path. This is confiusing to me. Are we talking about two different concepts here? or dose EIGRP caculate the link cost to the neighbors also using the minimum bandwidth link between source and destination? if yes, but how and to which destination reference point? any answer would be very much appreciated. _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Full duplex and a hub
Never seen that on a hub (hubs should of course not work with duplex) However, I have seen this 'faking full-duplex' in other situations. Lights on the switch (and the routers) indicated full duplex but data transfers (in different directions at the same time) seemed slow. I cleared the counters on the interfaces then inititiated massive transfers in both directions. This was to see if any collisions showed up in "sh int" (indicating that the full-duplex lights were 'full of it' [to use a tech term]). The collision count soared. Cisco confirmed that this was an effective (albeit screwy) way to confirm duplex status (or the lack thereof) notwithstanding the status lights. Although that test is not IOS-independent, it should work. My cure was to upgrade the IOS on the routers. >From: "Sasha" <[EMAIL PROTECTED]> >Reply-To: "Sasha" <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: Full duplex and a hub >Date: Wed, 14 Mar 2001 10:24:19 +0100 > >Hi ALL, >a fast Ether port on a cisco switch (2900XL) >connected to a hub (3com repeater) 10/100 port >reports auto-negotiated full-duplex, and works fine. >How can a normal hub (no buffering!) accept full-duplex? >To my undestanding this is impossible... >Am I wrong? >And, is there a simple way to check the duplex mode >of a line by some IOS-independent method? >Thanks. >Alex >== > > >_ >FAQ, list archives, and subscription info: >http://www.groupstudy.com/list/cisco.html >Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
off topic: PIX DHCP (client) Implementation?
Is anyone aware of any 'unique' characteristics regarding the DHCP (client) implementation on PIX 5.x? I tried assigning an IP to the outside interface via dhcp with a linksys switch dhcp server and it failed. When I plugged it straight into my cable modem and repeated the process, it worked just fine. Perhaps the linksys dhcp server component is flawed somehow (even though it works just fine for assigning addresses to other DHCP clients (wintel boxes))?? I replicated the failure three times and also ran debug on the PIX dhcp function with no useful results. (Given the rampant rumors re instability, I already placed knee pads under the chassis, but oddly enough that didn't help.) The only thing I could find online was the following excerpt: Note: Use of the DHCP client feature to acquire an IP address from a generic DHCP server is not supported. (source: http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_v53/config/advanced.htm#xtocid57942 ) [So can I assume that my cable company has invested some portion of my huge monthly bills in a "name brand" DHCP server?] Thanks for any info. _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
off-topic: Is a crystal ball called for?
The info below is an excerpt from a recent "C r a m s e s s i o n News" article (so it's presumably valid, I would hope, but I didn't write it) entitled "Why I don't want to be an M C S E" -- ___ Unfortunately, you are not distinguishing yourself from the crowd with an M C S E, anymore (duh*). You are the crowd. While there are around 375,000 M C S E s, there are only 60,000 O C P s, 18,000 Citrix C C A s, 10,000 C I W Professionals, and 5,159 Cisco C C I E s for example. ___ (*) - emphasis/sarcasm added So I'm wondering if anyone has any good estimate (+/- 10,000) on Cisco numbers _other_than_ the much pointed to C C I E census figures? It would be nice to have answers to questions like: Are there well over 100,000 C C N P s? Are there more C C N A s than people on the face of the planet?

MCNS - ephemeral Pix commands?
Several commands on the PIX have "come and gone" over time. Without getting into the NDA swamp, does anyone know if Cisco generally favors "older" or "newer" commands? My concern is over some type of fill-in-the-blank command scenario where something like an ACCESS-LIST approach would be valid on one PIX version and using "OUTBOUND" would be valid on another.
