Cisco Switching/Routing :: 2960 Files Copy Crossing Office LAN Is Super Slow
Apr 16, 2012
Two computers (XP and Win7) connected on office LAN, cisco 2960, not same switches, but all in the same rack, and link togeter, same IP subnet, tried to copy some kind of 26G files from one to another, using Windows share folders, and it showed need 23 hours to finish the copying.It's not the first time, actually we always experienced very slow speed when copying files on Windows share folders. Did not see any particualler message on the switch. ports are all full/100m.

Basic info: SBS 2008 (64bit), XP-sp3 (32bit) workstations, gigabit switch, SEP. App is Sage Masterbuilder.Network config: Server is 1gb to switch over CAT6. All the workstations are 100mb over CAT5. SEP is set to exclude all pertinent files on both the server and workstations.Problem: The program is called MasterBuilder and does job costing and much more. In the job costing feature there is an option to "Compute" job costing. In version 16.x, when the "Compute" was performed the task was done very quickly. After an upgrade to version 17.x it is very SLOW. According to tech support, our network is at fault since it is a database function over the network.Troubleshooting done: Tech support blamed our network speed (100mb) and switch. We had a Netgear 100mb switch so we replaced it with a GB switch however the cabling will not support GB. Being a managed switch I set all the ports to 100mb except the server port. Even tried the server plugged into a 100mb port and no change. I am confident there are no speed issues on our network. All other programs perform flawlessly. ACAD, Exchange, data transfers and many other high data use programs work perfectly. I updated the network card drivers in the server as well. There are no performance or resource issues on the workstations. I monitored the network traffic at the workstations, server and switch with no issues and about 2.5% utilization during the slow "Compute" process. The switch shows no errors at all, no collisions, no dropped packets, nothing. I also disabled the SEP.
During testing and while the slow "Compute" was going on, I copied a large folder (400mb) from the server to the workstations see the impact on network utilization. As soon as I start the copy process the "Compute" process speeds up to normal and zips by as it should. As soon as I cancel the copy process the "Compute" drops right back to very slow.

I am trying to research the possiblity of backing up IOS and configurations from an Etherswitch module, and being able to store the files onto the Host Router's flash (3925 ISR). and then being able to recover that IOS and configuration, in case I have to replace the Etherswitch Module.

Every link and guide i see about stacking two 3750 switch , the port 1 is connected to port 2 on the other switch and vice versa
i mean you can connect port 1 to port 1 on the other and connect their port 2 to each other
1- is it any benefit in the cross connection ?
2- do i encounter any problem if i stack a 24ts with a 48ts or a 12s-s (all are 3750)
3-i stacked two switches with each other and the ports became 1/0/* and 2/0/* and then i removed stack but on second switch the ports are still 2/0* !! when there is only one switch the interfaces should be 1/0/*

Internet VERY choppy on one computer, has happened on more than one network, both wireless and wired. I've even reinstalled Windows 7 on the machine from scratch the problem is still there.The internet goes VERY slow like 10 minutes a page sort of slow. Almost feels like its being choked but from what i can see theres no programs taking bandwidth etc.I've searched all over the net and can't find anything. I can give any information needed.The machine is currently on wireless but the wireless signal is great as i use other device on it in the same area and there perfect.

Normally use internet explorer 9, but I've tried Firefox and Chrome also.For some weird reason the Wi-Fi on my computer is super slow. My roommate has no problems at all. Same issue when only one of us are connected. What's really weird is that it's only on my home network the speed is a problem. At school and at other family members houses everything is working perfectly. I now use wired internet connection, and when I take a speedtest it is around 13MB, so the speed is pretty good.
I can mention that sometimes if my computer has been closed and the cable is taken out, when I turn the computer back on the Wi-Fi is suddenly working perfectly. Only for a while though, and then it's not working anymore. Has happened more rarely recently.I've been having this problem for around 7weeks now. When I first discovered the problem I tried to uninstall the latest updates (among windows updates), and it actually worked. But I want my computer to be up to date, so it's not a go to use those settings.
I have tried to reset the router to factory settings, but that did not work.We share internet with our landlord, so to privatize what we do, it's set up like this: Landlords modem -> switch in our apartment -> wireless router But that should not be problem. It's working on everyone else's computers. My mobile phone as no issues either;I've tried to update the driver on the wireless card, but it's up to date.

I had my Dir-655 router for over a year & this is is a first.My firmware is 1.21 & I only use my router for gaming when I'm not on my PC for home use. I have only one PC in the house that is not shared, I have also not downloaded any virus or maleware.So the past month I decided to buy a wired ethernet cord to connect to my gaming systems rather than using the wireless option to get an extra bit of speed. That has been working fine up till yesterday when all of a sudden my download speeds dropped from around 20Mb down to barely 1Mb down (I can't even get the speed test site to fully load anymore). The upload & ping remains unchanged though. Only my Download speed is being affected. This is both when I'm on the PC & when I'm online gaming.
I unplugged my D-Link router & plugged my modem directly to my PC & I got back the 20+Mb speed, so the modem or cable company are not at fault (I even called them to see if there were any problems on there end).
-I tried turning off my Firewall on my PC.
-Resetting & rebooting both my modem/router/PC.
-using different DNS numbers.
-using /flushdns.
-using /Iprenew.
-Messing around with my router configurations such as:
turning off QoS Engine.
turning off wireless.
turned of MAC filtering.
unchecked "Add DHCP Reservation".
unchecked SIP.
None of it worked. I'm still browsing at around 56k dial up speed for the past day+!I read up on the internet for similar problems, but the only solutions I saw was turning off the firewall on the PC, but that hasn't worked at all.

I used the ASA 5510 and in these days, facing the problem is internet is very slow. When i check in real-time log viewer debugging, i found the following logs 6|Jun 29 2011|15:47:53|106015|123.123.123.123|416|111.222.111.222|80|Deny TCP (no connection) from 123.123.123.123/416 to 111.222.111.222/80 flags ACK on interface Inside 4|Jun 29 2011|15:47:53|106023|123.123.123.123|852|111.222.111.222|80|Deny tcp src Inside:123.123.123.123/852 dst Outside: 111.222.111.222/80 by access-group "Internal_access_in" [0x0, 0x0] a lot of log message are come out and I notice that 111.222.111.222 ip is try to attack my network. In that moment, my network is very slow and nearly to be down. When I block with that ip by access list, network is up again. But after a few moment, attack from other ip, it's so terrible and so tired to block a lot of ip by acl.

I have a network using windows home server 1, with 3 computers hooked up to it. Two of them work fine but the 3rd computer cannot successfully copy a file to the network. However, I can copy a file from the network to computer 3.This started suddenly about a week ago and there were no driver updates or anything changed that would cause this. When I copy a file from the network to computer 3 I get about 80mb/second. When I try the reverse, it pauses and after about 5 seconds I get a message saying:There is a problem accessing \serverserverfolder. Make sure you are connected to the network and try again.If I try to copy a small file of a few megabytes it will copy though.

I need to do a backup on our laptop prior to beginning the malware removal process. I need to move 22GB+. There is plenty of room on our desktop to store the files.Would it be best to use file sharing between the 2 PCs? They are both USB connected to the same router. Or, is it possible to transfer the files by connecting them directly to each other via USB?

My E1500 worked perfectly before. Today CiscoConnect notified me to upgrade my router. After I've done that, the wifi connection speed is super slow. But when I use hardwire to connect, the speed is as fast as before

Just upgraded my E4200 to firmware 1.0.03 (from 1.0.01). I have some new issues, questions, and some outstanding issues.
1) Web interface over https is now painfully slow.
2) Does DDNS work in bridge mode? DynDNS allows the sending of an update without an IP address, so it should be able to work.
3) Does accessing the management interface in bridge mode count as local or remote?
4) I'd really like to be able to get WOL working through the router. I managed to create a static DHCP reservation for 192.168.1.254 to ff:ff:ff:ff:ff:ff, but I don't think the router added that entry to the ARP table, is there any way to do this.
(I think have WOL forwarded to 192.168.1.254). 5) Should the router be providing some local dns hostnames? For example I have the device name set up in the local network setup, but it won't resolve. Similar for connected devices, especially those with with a DHCP reservation. 6) In bridge mode, does it matter which port is used to connect to the other network device? Does it have to be the WAN port?

For the past year my wireless has been working great and I have being playing games/doing homework with no hassle. Yestetday my internet connection became very slow. After countless restarts, router/modem resets nothing has changed and I only get like 5kb of download speed. Since my internet connection was lost naturally I unplugged the wireless card and re-plugged it, didn't change anything. After that I restarted my computer, but nothing changed. AFTER THAT I unplugged my router, then reset my router to factory settings, which did not change anything. Since everything was backed up I thought I would reinstall Windows 7 to nuke any hidden problems. After 2 reinstalls of Windows 7, nothing has changed. Next I had Comcast reset my connection with them which did not work. Though it did work with my brothers desktop. After some more time just fiddling around my connection went back to lightning speeds. no.....4 hours later my connection went dead.At all times my computer will see my network but it either will not connect to it or it is really really slow now.

I record videos after motion detection on the cameras sd-card. Is there a way to copy all the files from sd-card to the pc? I wasn't able to copy them with the web-interface. I don't just want to delete the videos from time to time. I also want to archive them local.

I have a small office with 4 employees. We all work off of laptops (although I am about to bring a desktop in because I need a little more horsepower for some graphic stuff).I have a number of files I would like everybody to share, update and save so we can all access them. I also need the ability to access them remotely.

I've rolled back my E4200 router to the old firmware 1.0.0.1, then set up a media server.It generally works (e.g. it streams pre-existing media files to other devices). I can copy to this external drive small (say, < 1 MB) files. The drive has enough free space. However, I cannot copy to this external drive large (e.g. 700 MB) files.

It seems I have seen this before (and even done it once a few years ago).. but it has been a while. I have a stack with a Cisco 3750 stack that I have to replace a member.The replacement switch is a 3750X.
I think I have to upgrade the IOS of the older switch to be the same as the 3750X.
Current switch: WS-C3750G-48TS 12.2(46)SE
TO BE ADDED WS-c3570X-48 15.0 (1)SE2
It seems to me there was a way to upgrade the older switch IOS from the newer switch or downgrade the newer switch with the older IOS.I dont have the Cisco account to download updated IOSs.

I know we can use copy & Paste, my questions are:
1. Before that, do I need to wipe out the existing confi on the brand new switch?
2. About using TFTP, how does this new switch connects to the TFTP? Does it mean I have to assign a real IP and put it on our network?

I have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
[Code]...
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.

I am trying to configure a switch that was given to me. They don't know the password to anything. I have already tried to recover it. The problem is, the switch doesn't load flash, or will copy flash from xmodem either. It also doesnt load the helper or boot. It is user mode and lets me do nothing. It doesnt let me use the enable command to get into it. I would like to start the config from scratch. Its a 3500xl switch, 24 ports. I dont know what to do with it. I am trying to study for my CCENT Exam and would like a switch that worked.
