RE: CCNP Switching [7:56559]
I can't speak from a great deal of experience here, but set based switches seem easier to configure, because you can change settings for multiple ports with one command. For example, on a CAT5K, to change duplex speed to full on a whole module (12 port 10bFL) I type Set port duplex 3/1-12 full And it sets it on all 12 interfaces. Doing this in an IOS based switch would require the use of notepad and cut and paste :) It would be a shame if Cisco did migrate away from the set based language.

Well, once you create the filter, you can look at your access logs to see what has been 'denied' you would see the source address and using good ol troubleshooting tools, etc you could find out which computer/user is using it! Just one way in which to skin this particular cat! Another option, is don't give users administrator rights to their machines. Removing this right, stops them from installing the clients, be it MSN, Yahoo, etc?

I hear cisco is doing away with set based. Apparently the ccie lab includes two 3550's which are IOS based. Whoever told me this said cisco bought the set based system and created IOS themselves, so the plan is to do away with set based and go completely with their own stuff.

This is correct. Remember that the Catalyst switch line was originally made by Kalpana (and Grand Junction sort of), which developed the set-based commands independently of any Cisco involvement. Cisco wisely realizes that having a "unified front" makes their products more attractive to us lowly engineers, and IMO the unification is a long time coming! ;-) BJ Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=56587&t=56559 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Access list on dialer interface [7:56584]
Pat I have discovered the reason, a little more complex that I first imagined. Isn't it always. The router was configured with Legacy DDR which meant that inbound calls where only using the first dialer. I changed it to use 'dialer pool-member x' on the PRI interface with 'dialer pool' in the dialers. There where a few little changes but this fixed the problem as the call was now coming into the correct interface (dialer2) and thus assigning the access list. Thanks for your help.

OT: Firewall Reporting [7:56596]
I am looking for a firewall reporting package that can handle a large number of units for under 200 dollars per firewall per year, the reports will be generated from a standard syslog output from the firewalls. I really just need basic reporting functionality, like bandwith usage by IP address, bandwidth usage totals, and website hits. Does anyone know of a product other than WebTrends, they are really expensive. Guy H.

Re: IPX bridge on 6509?? [7:56533]

If I make the SVIs bridged interfaces, am I not now bridging IP as well? Can you separate the protocols that you wish to bridge from the ones you wish to route?. (Are VLANs > > new to this network? Was it all one big broadcast domain Ø before??) Yes, VLANs are new to this network and it is essentially just one big broadcast domain. This is the interface that I am going to move from the 7206 to the 6509. interface FastEthernet6/0 ip address 192.168.49.61 255.255.255.252 secondary ip address 192.168.79.1 255.255.255.0 secondary ip address 192.168.80.1 255.255.255.0 secondary ip address 192.168.250.1 255.255.255.0 secondary ip address 192.168.38.1 255.255.255.0 secondary ip address 10.24.75.33 255.255.255.248 secondary ip address 172.22.8.1 255.255.248.0 no ip directed-broadcast full-duplex ipx encapsulation SAP ipx network FFA0001 The 7206 currently has a bunch of 2924's with servers (and the local LAN) hung off of it. I have a new 6509 w/ redundant sup2/msfc2/pfc2 running native 12.1(11b)E7 that will have four 4006's connected to it. All of the servers will be moved onto the 4006's and I wanted to now perform the routing between these networks on the 6509. Again, I wish to break out all of the IP networks into separate VLANs. Unfortunately a few of these ranges have servers that are using IPX as well. I need to bridge the FFA0001 network between some of these VLANs until I can get all of the clients to use IP. I was just trying to avoid having to bridge the IP as well, because at that point I effectively have the same network I started with. Hopefully, this made more sense. Thanks.

Re: FXO vs other Analog Voice Card [7:56536]
I knew this question was going to lead to trouble! Okay, here goes. First thing, if the incoming call digit string will be matched to the destination-pattern of a VoX dial-peer, there is no prefix or forward command available. In a VoX dial-peer you are mapping a telephone address (the destination-pattern) to a Network address (session target with Layer 2 or Layer 3 address). This is your voice routing table! This is the logical routing plan you created when you designed this voice network. This is a static routing table you created. Why would you map an address one way, then try to modify it before you sent it to the ultimate destination? Dial plans are simply static routing tables. There is no EIGRP for voice networks, yet. Digit stripping happens ONLY on POTS dial-peers. Digits described explicitly (333 in 333) are consumed during the digit analysis. The prefix command can be used to replace the consumed digits, or the forward digits command can direct that X number of digits are to be preserved and sent across the POTS line once it is active. The E&M should do what you want if you want to only send 4 digits to the other end. The VoIP dial-peer will send all digits that match the destination-pattern statement. This all depends on what you are trying accomplish. This isn't clear because you are mixing FXOs and E&Ms which you can't do. Maybe this will get you aimed in the right direction. Feel free to email me with what you are trying to do. the configuration may be very simple. Bruce Paul Oh wrote: Hello All, When FXO receives a phone call, it strips out corresponding called-number that matches destination pattern settings..

Well...you calling it "LLQ within CBWFQ" isn't Cisco canon, but your config below is a fine LLQ configuration. I've noticed (especially in my studies of QoS) that the only differentiator between acronym-based technologies (like LLQ and CBWFQ) is just the addition of one little command in an otherwise "old" config.

So this step is definitely possible > 2. A PC host receives a tcp frame. Layer 3 drops it. Entries in the ARP cache on a Cisco router last 4 hours. So a router could easily send a frame to a MAC address with the wrong IP address if the IP address on the PC host had been changed. The router wouldn't have sent an ARP request if the mapping were already in the ARP cache though. Did you mean step 1 and step 2 to be linked? The sender sends an ARP that is ignored and then sends a frame anyway? Is this question a treat or a trick? :-) I'm sure you have something trickier in mind than what I came up with, but I just can't think of anything else. I wracked my brains thinking about IP spoofing, NAT, Proxy ARP and can't think of anything. Of course software bugs could cause something like this, but that's probbaly not what you had in mind either. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > Questions: > Which of the above is possible/not possible?

Video Priority 2 [7:56610]
Hi, I read in Cisco pages (sorry, can´t remember the URL) to not give priority to the video, just give it to the audio. I think it may be because of the jitter problem with voice signal and the possibility to give strict priority to voice without starve other traffic, as opposite to video, that can be very high bandwidth. But in some applications, as Windows Media Server, the audio and video are transmitted together (at least it is what I can see with Sniffer) I am trying to clarify this topic, so thanks in advanced for any reply.

RE: PIX501 to VPN concentrator through NAT [7:56615]
Elijah, Thanks for your answer.. Here is also a little more info for anyone interested that I found during my research.. Heres why 1 to 1 static NAT should work with IPSEC VPN... To be compliant as an IPSec VPN a product needs to support 2 things: IKE (Internet Key Exchange which runs on UDP/500) and IPSec (AH and/or ESP) which do NOT run on TCP or UDP at all. IPSec is it's own protocol number, like ICMP, TCP, RIP, etc. The reason that many to one NAT breaks most IPSec implementations is that it changes the TCP/UDP port numbers so that it can map the connections to a single IP. This breaks IKE because IKE has to run on UDP/500 and it can not be changed. It also does not work for IPSec, because IPSec does not use UDP or TCP port numbers (although original user packets which are TCP/UDP based are often tunneled inside of IPSec packets). IPSec can be made to work when 1to1 NAT is used. IKE will not be broken because no port mapping occurs. IPSec can be made to function as long as AH (which computes a checksum signature which includes the original IP address) is turned off. ESP also computes a checksum signature, but does not use the original IP as part of it, so therefore a NATted packet works in this environment. IPSec does support "TCP based" VPNs however, as tunnel-mode IPSec carries TCP sessions through the IPSec session. Here is why PAT will work when using the VPN client... Encapsulating Security Payload Protocol 50 (Encapsulating Security Payload [ESP]) handles the encrypted/encapsulated packets of IPSec. Most PAT devices don't work with ESP since they have been programmed to work only with Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP). In addition, PAT devices are unable to map multiple security parameter indexes (SPIs). The NAT transparent mode in the VPN 3000 Client solves this problem by encapsulating ESP within UDP and sending it to a negotiated port. The name of the attribute to activate on the VPN 3000 Concentrator is IPSec through NAT. How Does NAT Transparent Mode Work? Activating IPSec transparent mode on the VPN Concentrator creates non-visible filter rules and applies them to the public filter. The configured port number is then passed to the VPN Client transparently when the VPN Client connects. On the inbound side, UDP inbound traffic from that port passes directly to IPSec for processing. Traffic is decrypted and decapsulated, and then routed normally. On the outbound side, IPSec encrypts, encapsulates and then applies a UDP header (if so configured). The runtime filter rules are deactivated and deleted from the appropriate filter under three conditions: when IPSec over UDP is disabled for a group, when the group is deleted, or when the last active IPSec over UDP SA on that port is deleted. Keepalives are sent to prevent a NAT device from closing the port mapping due to inactivity. But even though the remote PIX is acting as a VPN client "easyvpn client" it still can't use PAT because its not able to negotiate with the VPN concentrator to encapsulate its packets in UDP and according to the TAC engineer that I asked they have no plans of making that possible.

Re: Question on ATM OC-3 WAN connection and TcpWindowSize [7:56617]
This is a common complaint. Sprint is most likely correct, your application simply can't utilize the bandwidth. The samller your window size the less bandwidth you will utilize. You can see this first hand by using ttcp between the two routers and changing the window size on the router with the "ip tcp window-size x" comand.

Problems w/Hyperterminal?? [7:56619]
Hi all -- I'm suffering thru a terrible newbies type problem and cannot seem to identify the error of my ways. I know it's something very basic -- and it brings back memories of high school geometry homework where I stared at objects for hours on end trying to understand!!! The thrust of my pitiful situation is: I cannot "ping" from hyperterminal -- altho' I can readily "ping" from a DOS prompt on the same PC. I have the parameters set properly 8-N-1-None -- and I have tried with the TFTP server setup on the same PC and on another in my home network (I have 10 pcs in my home network -- most old -- but they still work!). Neither works. Any suggestions. And please don't waste time flaming me -- I know I should be able to figure this out -- but even after researching the archives and CCO, I am no closer to a solution than I am to passing the LAB on the first try! So any and all helpful suggestions would be welcome. Thanks to all -- in advance!!

R. Benjamin Kessler wrote: > > You could be experiencing the "long, fat network" (LFN) problem. Could be a long, fat network problem, if this is indeed a long network (or long-delay network). To learn more about LFNs and the TCP window scale option for use on LFNs, see RFC 1323. The issue is that the largest window size you can have with TCP is 65 KBytes since the Window size field is only 2 bytes. The window scale extension expands the definition of the TCP window to 32 bits and then uses a scale factor to carry this 32-bit value in the 16-bit Window field of the TCP header The scale factor is carried in a new TCP option, Window Scale. This option is sent only in a SYN segment (a segment with the SYN bit on), hence the window scale is fixed in each direction when a connection is opened. Lately, I have actually seen devices using this scale extension, so I think it is supported on modern operating systems. It's more likely that it's not an LFN-related issue, though. It's more likely that the TCP window size isn't set to its possible max (65 Kbytes) even without window scaling. To start with, he should max it out to 65 Kbytes and not worry about the scaling factor, which could cause problems if not supported on all hosts. Benjamin and MADMAN gave good answers, but I have a few more comments below. This is a good chance to learn about capacity versus throughput. See below > > How far apart are these locations?

You still have 155 Mbps. That's your capacity, in other words, the capability for sending bits at a certain rate. Your output interface could send bits that fast, if the host applications gave it bits that quickly. Throughput is not the same thing as capacity. Capacity is the capability. Throughput is a measurement of the actual amount of data transferred in a certain amount of time. Network protocols packetize data. They don't whip out bits at the rate specified by the capacity. The following items affect throughput: * Packet size. Bigger packets result in higher throughput for bulk transfers. HTTP tends to not use a full size packet. FTP usually does. * Inter-packet gap. There's time between packets when no data is sent. * Turn around time at the client and server to process data and send the next request for more data. The CPU speeds of the clients and servers affect this, as do many other factors. * Hard disk access time. Depending on the application, no data will be sent while the client or server read/write from the hard drive, a mechanical device that can contribute heavily to throughput. * The amount of memory on the clients and servers can affect throughput. At what point does the application have to write to disk to free up RAM to receive more data? * Protocol behavior. Is it a request/response (ping/pong) protocol? Does it require an ACK per packet or does it support windowing? * Error rates. Are packets getting dropped and needing to be retransmitted? > Sprint told me I need to change the registry: > TcpWindowSize to get better throughput. Have anyone > experienced this before? That would help TCP applications. Think about how TCP works. Each side specifies a window size. The other side can output numerous packets to fill that window, without stopping and waiting for an ACK. When it fills the window, it must stop and wait for an ACK. It's this stopping when your throughput is 0 bps that causes your throughput for the entire file/data transfer to be low. If the host has a big window size, the other side can send and send and send, without stopping as much. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > Thanks in advance. > > Kim. > > __ > Do you Yahoo!? > HotJobs - Search new jobs daily now > http://hotjobs.yahoo.com/ > > Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=56620&t=56614 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

See our BGP convergence drafts, Clock synchronization and time skew are problems related to all cross-system, cross-network measurement. In the SNMP world, this is generally avoided by utilizing a few different methods (usually combined): 1) External NTP or GPS time synchronization (or internal atomic clocks) 2) Polling sysUpTime or ifCounterDiscontinuityTime 3) Polling the above variables with GET-BULK's at the same time the other variables are polled If using external sources for time synchronization, you also have to take into account things like jitter (which you wouldn't necessarily have to account for in many applications like TCP/HTTP). An extra problem with time skew is the rate at which the user-level or kernel-level timestamps are created (e.g. when sending test packets). The kernel-level clock granularities on PC (x86) computers cause at least 10ms jitter, while NTP adjustment for VCO gain require 1 ms (see RFC 1305 for more details or Google Groups below: http://groups.google.com/groups?as_ugroup=comp.protocols.time.ntp ). One way to overcome this problem is done with a program like rude (http://rude.sourceforge.net/), which dispatches packets with a pecision of 1us. Normally, user-level timestamps are less accurate than even kernel-level timestamps, but in this case they are not ;> > First, routers may not give sufficient precision in measurement, > because they rate-limit ICMP to protect against ICMP floods, or > simply don't prioritize it highly.

Rate-limiting is actually default in some versions of IOS for ICMP, add into things like SPD (selective packet discard) and the primary fact that ICMP takes a different path in software/hardware (every hardware has different ways of doing "life-of-a-packet")... all this makes ICMP fairly useless as an accurate measurement. There are also problems with ECMP and ICMP (I love how the two terms are totally unrelated otherwise), and traceroute doesn't like ECMP much either. Sort of sad that after 18 years or so, VJ's tool "traceroute" is still the only game in town (please don't mention things like mtr or visualpulse, which effectively are the same thing). > Second, the router may or may not have the capacity to capture and > store a statistically valid amount of data.

NetFlow, Cisco debugs (yes, if possible and generally not), packet capture infrastructure (better to use taps than SPAN's for similar timing reasons), and other tools are great for measurement. It's good to have other options. Using optical/copper taps along with a FreeBSD box running tcpdump (http://www.tcpdump.org/) and tcpdump contrib tools like tcptrace (http://www.tcpdump.org/related.html) are really useful for determining things like TCP Goodput, etc. These can generally be more accurate than ping/traceroute for determining performance problems, but only if you are skilled with ARP/IP/TCP/HTTP capture output and network/server hardware (e.g. routers, switches, NIC's, drivers) and/or TCP/IP stacks (sendspace/recvspace, socket buffers, maxconn's, mss max/avg/min, retransmissions, retransmission timers, SACK, window sizes, et al). Commercial products can sometimes be substituted (e.g. Niksun NetVCR or Finisar/Shomiti Surveyor - which are sort of like NAI SnifferPro, except they work). Generally, network problems in today's network (particularly problems with HTTP applications) generally revolve only around a few things inside the networks (at the server or client end): 1) Server/Client NIC problems 2) TCP/IP stack problems (visible by zero window sizes / window resets or too many retransmissions) 3) Layer 2 Spanning-Tree or HSRP/VRRP switch/router problems 4) Layer 3 BGP/OSPF/EIGRP convergence router problems 5) Layer 3 CEF or forwarding router problems 6) ACL or firewall problems (handling high pps or number of sessions) Even more rarely, they happen outside of the network (on the Internet): 1) ISP rolling reboots during maintenance or unscheduled outage 2) ISP peering issues generally caused by congestion between two peers 3) ISP Layer 3 BGP/OSPF/ISIS/MPLS convergence router problems 4) ISP Layer 3 CEF or forwarding router problems Sometimes they aren't network-related but instead browser (i.e. application) or server-related: 1) Mis-configured or "bad-state" client or server (including proxies
RE: Problems w/Hyperterminal?? [7:56619]
I do understand the basics -- but I'm not able to ping anything from hyperterminal -- (1) the router, (2) the PC -- but I am able to ping the router from DOS. My problem arose when I was unable to "copy flash tftp" I tried by process of elimination to id the problem -- and it seemed to be hyperterminal. However, in the past few moments, someone else wrote to me and inquired about my hub (10/100 or 100!) -- mine is 100 only. Thus, the routers (at 10) would not communicate. I'm going to try and swap out the hub and see if this helps. I'm not a 100% certain that this will fix the problem -- but I'm going to try it and see. One never knows. Be back in a few . . . .

Re: Question on ATM OC-3 WAN connection and TcpWindowSize [7:56627]
I once had a similar problem. The problem ended up being that the individual files were so small that the ftp client simply couldn't get up to speed. It would basically start slow for each file and accelerate during the upload. They were so small, though, that basically it keeps starting over from 0. I discovered that by compressing files using whatever program you prefer (winzip, winrar, tar) that making it one file allowed it to get up to full speed utilization. Not sure if this will help.

RE: Problems w/Hyperterminal?? [7:56619]
You can use TCP/IP (Winsock) to connect to a telnet type device with hyperterminal. However, in order to ping, obviously, you have to be connected to something. If you are connected to a router (or other telnet type device), try running a traceroute to the device you're trying to ping.

Re: Problems w/Hyperterminal?? [7:56619]
what port is your hyperterminal set up to use? surely not your ethernet port, since one uses hyperterminal for serial communications. if you can ping from DOS to the router, then the ethernet segment is OK but your hyperterminal provides you only with a session to the router or switch.

How could HyperTermianl affect your ability to copy a file from the router to the PC? HyperTerminal just lets you see and control what's happening on the router. It's just a Terminal. I guess newer versions do Telnet too, but it's still just acting like a Terminal. (I don't use HyperTerminal anymore. I use SecureCRT. It's much better.) You can probably leave it out of the equation though. Priscilla > > However, in the past few moments, someone else wrote to me and > inquired > about my hub (10/100 or 100!) -- mine is 100 only.

RE: Problems w/Hyperterminal?? [7:56619]
When setting up a connection in Hyperterm you can select TCP/IP Winsock along with "direct to COM X" If you want to use Hyperterm as a telnet client (though I can't think of any benefit over using a generic DOS prompt - I use Procomm, myself) you only need to make sure that your connection properties have that specified. If you are setting your connection up as Priscilla has mentioned, where you are emulating a terminal attached to a remote station - i.e. a device directly attached to your serial/COM port, then as has been stated, you would be pinging not from your local machine, but rather the ICMP echo would originate from the directly connected device.

Bored@Work [7:56642]
Budgets tight, no new big projects on the horizon. Everything working smoothly. I should make use of the time and get a CCIE right? My background: 20+ years in IT, mostly Unix (Sun, HP, etc), NT, various programming languages, bla, bla. Founded an ISP but closed it down after it sucked me dry last year. 4 years using Cisco (36XX, 26XX, 29XX, 17XX, PIX), . Engineering degree. Now leading a small Infrastructure group of 12 with a multinational corporate conglomerate. I took a couple of practice CCIE tests I found on-line and got better than 1/2 right (do they really have multiple choice where you need to select more than 1 answer to be right? And those questions where non of the choices are right?). What study materials are recommended? Which books and practice tests should I get? Seems to be a lot of stuff out there. It can't all be good. -John B.

With Telnet you're just emulating a terminal also. Either way, when you type "ping" the ping packet originates from the device that is hosting your terminal session. He seemed to think HyperTerminal was causing a problem when he typed "ping" into the HyterTerminal window. Whether you're using RS-232 or RS-422 or Ethernet, and whether you're using HyperTerminal, a virtual terminal, VTY, Telnet, a Teltype, or one of those old DEC VT100 terminals, the result is the same. Each character is sent to the host operating system (IOS in this case) and the operating system acts as if you were typing directly into it. The ping gets executed at the host (router) when you press carriage return. Probably a carriage return/line feed is sent to the OS. Then the ping message is sent from the router. Sorry but I'm irritated by all this. ;-) We got way off base by pointing out that HyperTerminal can do Telnet too. I'd forgotten that you could do Telnet with HyperTerminal, admittedly, but my reaction is Whoopee! What does it have to do with the problem? His original message talked about asynchronous serial stuff like setting the bit rate and number of stop bits. Then he launched into a discussion of Ethernet hubs. Hello? Did he eat too much Halloween candy? Or did I? ;-) What does he actually have connected in his lab? How can we help without knowing that? _ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > HTH > Bill Creighton CCNP > Senior System Engineer > Motorola > iDEN CNRC Packet Data / MPS > > > -Original Message- > From: The Long and Winding Road > [mailto:groupstudyspamtest@;cl.cncdsl.com] > Sent: Thursday, October 31, 2002 4:09 PM > To: [EMAIL PROTECTED] > Subject: Re: Problems w/Hyperterminal??

If a station can send a packet, such as a ping, it's unlikely that there are any physical or data-link-layer problems. If it can't receive a packet, it makes sense to look above those layers. There are some unidirectional problems, but they are pretty rare. Some protocols, including STP, deal with the infamous "one-way connectivity" problem, but I bet it happens pretty rarely. I had a new theory about what would cause his symptoms, or at least what I think his symptoms are: PC can ping router. PC can Telnet to router?? (we're not sure if he's Telnetting or not) Router can't ping PC. Router can't TFTP a file to the PC. Possible explanation: the PC is running a firewall! From my knowledge of the default behavior of many personal firewalls, this seems rather likely. There could be an access list on the router too that could cause this. Gotta run. I promise no more messages on this topic! ;-) ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=56648&t=56619 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Clearing ARP. [7:56651]
We have a Cat5500 with an odd problem. There is a customer with a Vlan setup on 2 RSM's using HSRP. The Vlan is using a /29, with each RSM assigned an IP from the /29, a default gateway from the /29 which leaves 3 usable IP's for the customer. He has 2 devices plugged into 2 ethernet ports on the Cat5500, a Redback and a 3640, each has an IP from the /29, leaving one more to use. He wants to add a switch, so config the switch to use the last IP from the /29, assign the port to the Vlan and the switch should be accessable. I'm telnetted to the console of the switch and I can ping the 3640 and the Redback ok, but not the switch. A ping to the customers switch wants to go out an IP on an interface that does not exist and has not existed for a looong while. A show arp below shows two entries on the same port/vlan. 204.244.98.19 should not be there. I'd like to do a clear ARP on the console so that it will remove the old entry but should it have not removed it by now? We changed things over over year ago taking out the 98.19 address. My question though lies in what affect clearing the ARP table on the console will have on overall routing? Its just on the console of a Catalyst 5500, not on the RSM's. 64.114.55.67 is the gateway for Vlan1 which is the management Vlan for the RSM's. How quick does the ARP table get repopulated?

CSCdy32279 When the MAC address tables becomes full under certain conditions, a switch no longer stops forwarding traffic or populating the forwarding table. CSCdy43265 When the spanning tree state changes from learning to forwarding or from forwarding to blocking, a switch now sends a topology change trap. CSCdy55350 A switch no longer reloads when the autoconfiguration file includes VLAN configuration settings. CSCdy58823 The UniDirectional Link Detection (UDLD) protocol no longer disables Gigabit ports during startup when a mismatch state occurs with neighboring switches. CSCdy70273 Classifying traffic on a per-port, per-VLAN basis by using a class map now polices only the VLANS in the match VLAN list. Previously, all the VLANs were policed. CSCdy70850 If you enter the switchport port-security mac-address sticky and switchport port-security violation shutdown interface configuration commands on an interface, when a security violation occurs, the interface is errdisabled. CSCdy77891 If a switch continually updates the virtual routing and forwarding (VRF) table, the packet forwarding rate no longer decreases. * Open IOS Caveats http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12111ea1/ol261202.htm#xtocid27 Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=56652&t=56652 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Not so rarely Priscilla if we talk about fiber, I have to deal with that problem 3 or 4 times a year, unfortunately it's quite easy to damage only partially a fiber optic cable when a hospital is repairing any wall, disposing a room, ... (and they are always doing that sort of things!). Believe me, the "one-way connectivity" problem is one of the worst problems that you can have in a LAN.

RE: books for ccie written [7:56604]
hey jesse, thanks for replying. i have another question for u. i am an electrical engineer and pursuing my MS in telecommunications in US. i cleared my CCNA last year and have a working experience for little less than a year in networking field. Now i am in double mind, whether to go for CCNP or CCIE directly. I saw the course curriculum for both. I think i can manage CCIE written but not sure about the lab since i have just started with my hands on experience. so right now i am concentrating on CCIE written. Now if given a choice between CCIE written and CCNP, which one do u advice me to do. which one would help me in finding a good job according to u. Thanks.
