4500x losing connectivity to SG300 switches issue
I have a new Catalyst 4500X-16 SFP+ Switch with ten GLC-SX-MMD SFP modules connected to ten Cisco SG300-10 switches with MGBSX1 SFP modules. The 4500X is all default config except all I did was setup SSH so I can manage remotely. I have GB connectivity between small SG300-10 switches and 4500X switch without any problems at all, until the SG300 reboots. If power goes out or SG300 is restarted for any reason, it does not communicate with the 4500X switch any longer. If I restart the 4500X, then connectivity is restored. I don't see any port security setup or no ports are down...everything appears up, but I can't communicate until I restart the 4500X switch.
I'm not sure where to begin troubleshooting this one. I am putting battery units on each SG300-10 switch, but that is just a temporary fix and I'd like to get to the core of the problem.
4500X is running IOS-XE Version 3.05.00.E
Thanks in advance for any help you can provide.
Below is info on the 4500 switch...

WAP losing connections on 3524 + 3550's
Hi,
has anyone had problems with Wireless points (1200 series) suddenly losing connection to the switch (3524 and 3550's). We have replaced the switches with 3750's which has cured the problem. But we still have one 3524 which every month or so, just drops the connection to the WAP and therefore stops the inline power, and the WAP goes down.
Do they drop the connection due to inactivity?Cisco Aironet equipment operates best when you load all components with the most current version of the software. Upgrade to the latest versions of the software early in the troubleshooting process.

Why do I keep losing connection to my MIFI4510L
Why do I keep losing connection to my MIFI4510L. After a period of time this device disconnects from the internet. What do I have to do to correct this?
This seems to be a problem in various areas. I'm in Michigan north of Detroit, when they switched from 3G to 4G, reliability and speed dropped significantly. My first service calls were frustrating as the service tech told me I had unused WIFI setups on my PC and I needed to delete them. told him the device works everywhere else, but he was instant I delete the unused, imagine that fixed nothing. I was sent a replacement device (refurbished without a battery or back) which was worthless as it was different form what I have and could not be used, so I sent it back I have emailed the Customer Service VP for the region and after months of not getting the issue resolved I was told 4G service was in the process of being updated in my area and not to expect it to improve until sometime in 2013. Since the device detects 3G and 4G, it switches to 4G and connection often drops to 1 mbps and cannot even get a Google page. Under 3G, it was pretty consistent at 68 to 72 mbps. My options are to replace my 3G/4G device with a 3G only or change to a different service provider. I have a cottage basically on the fringe area and 3G connects at 68-72 99% of the time and outside of Boston, Washington north of Seattle (almost Canada), Texas, Chicago, etc, 4G works great, so it is not the device. Guess I'm not sure the push to 4G if they are not ready. Guess once the sale is complete they have you and if service is bad, oh well. The sad part, my current cell phone contacts are ending and I was seriously planning on leaving ATT to switch everything to Verizon based on service prior to the switch to 4G, but that does not make any sense now. My Apple 4G can be a hot spot and works great when I' m at home, but why pay for 2 different services. The other interesting note, I left Comcast due to poor service (internet was slow from 6am to 10pm or dropped completely) and now Verizon has teamed up with them... sure hope they are not the cause of poor internet service... like maybe Verizon is using them for internet service... I was told no... but problems started around the same time of the announcement. So based on responses from Verizon, I will check my other options. The commercials are great but reality is delivery, no so great.

Windows 8 keeps losing connectivity
Hi, not sure if this is unique but for the past few weeks Windows 8 has been losing connectivity every few minutes when browsing web pages, playing games etc. I am sure it's windows 8 as I have another work laptop using XP that I can be on all day via a
VPN and that does not drop at all (it would normally drop within a few seconds of losing connectivity). I've done a lot of searching on the net for the same issue, others seem to be having similar things happen such as slow speed but can't find anything that
matches, hence this separate question.
I have also tried swapping routers to no avail. The thing is, you wouldn't know anything had happened from the network connectivity. Suddenly a page won't load. The wireless connectivity at the bottom right of the screen shows a full 5 bars (not limited
connectivity). The way to get it back again is to leave it for a few minutes or disconnect from the router and reconnect again. Even whilst typing this I have had to do that twice.
I'd appreciate some suggestions!
Many Thanks, Paul.

Does this issue occur with both wireless and wired?
I suggest to perform these tests to troubleshoot the issue:

2 Temporary disable firewall and antivirus program
3 Logon with Safe Mode with Networking
4 Update framework for your router.

External drive conntected to Time Capsule keeps losing connection
I've been having this problem since I bought my TC over one year ago. Other than this everything works fine (aside from the occasional need for a restart).
I have an external 500GB drive attached to my 500GB TC via usb. I use the TC strictly for backups and the other drive to host my media files. When I want to use those files I switch on the drive. Only about half of the time does that work. When it does work everything is fine. I see the drive in the finder as expected.
When it doesn't work, I can see the drive name in the finder. But if I click to go into the folder, I get an error saying that the connection cannot be found.
It shows up in the Airport Utility as normal.
Powering the drive off and on does not help.
Relaunching the finder doesn't help either.
The only way I can connect to the drive again is to either logoff and log back into my mac, or restart the TC.
It seems that my computer is remembering some kind of network disk mounting settings that don't get refreshed when I turn on the drive, but then do get refreshed when I logoff and back in. Does anyone know how I could force that refresh to happen? Has anyone had this problem before?
Any suggestions would be much appreciated
PS all my software and firmware are the latest.
Thanks.OS X fan

Network Drives Losing Connection from Server 2012 to Windows 7 64bit Machines
I have about 20 users at my facility and recently upgraded our server from one running server 2003 to one running server 2012. Since that occurred, I have had numerous issues that I did not encounter on the old server.
Lately, users have been losing connection to the shared network drives randomly and constantly. The drives will come back on-line on their own but it could be 2 minutes or 30 minutes before they do and when users are in the middle of working on a document
from the network, they are unable to save until the drive comes back. Manually disconnecting and re-mapping them works sometimes but then the problem will re-occur. I have tried re-doing the shares and security settings and run a couple of supposed hotfixes
on the client side and the server side to no avail.
Now our regional office is suggesting that I re-connect the old server and then rebuild the new one with server 2008 r2, something I would like to avoid if possible.
I feel like this is a simple setting that I am missing, no conditions have changed except for the new server.
The server is a Intel Xeon CPU E5-2609 2.40GHz with Server 2012 64 bit on it. All computers (except on on 32 bit) are running Windows 7 Enterprise edition 64 bit.
Please help.I made this change to the registry on the server and am waiting to see if I have any more drops.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
Value:
autodisconnect
Data
type : REG_DWORD
Value:
ffff (Hex)
There was a client side change suggested but I am missing that value for the client side change and others in the organization who don't have it are not experiencing this problem. -
LaCie external hard drive keeps losing connection to Windows 8.1 computer
Hello all,
My LaCie external hard drive (Rugged version) seems like it keeps losing connection to my brand new Windows 8.1 laptop. The laptop is an HP Pavillion 15-p 133cl TouchSmart Notebook which I just got today. Basically, every few minutes, or if I nudge the external
a bit, the computer will seem like it disconnected and reconnected to the external hard drive in a split second and bring it up in the Windows Explorer. This external hard drive doesn't show any problems connecting to any other computer, but it has occurred
with 2/3 ports on this computer so far. I'm a bit worried, because I definitely DO NOT want the files on this external to get corrupted in any way. What should I do? Thanks a bunch.may I know your external HDD model, to check which USB version to isolate power and cable connection issue
if this is USB 3.0 try to attached at USB 3.0 at your laptop, your laptop has 2 USB 3.0 and 1 for 2.0, for external HDD with USB 2.0 sometimes need more power / more than 1 connection, sometimes the power will loose
but since the trigger it will disconnect if you nudge the HDD, I suggest back up data to your laptop first, try to change with other data or power cable, try also update your laptop chipset
try to check with other device to isolate port issue
may I know if you are using other PC, did your external HDD also will disconnect if you nudge it?
contact your external HDD manufactured to get some suggestion -

Why does my mouse keep losing connection every minute
why does my mouse keep losing connection every minute, its not the batteries
I'm having the same issue. Every so often it loses connection then re establishes. This goes on repeatedly.
If you change batteries while the computer is still active then it takes for ever to re connect.
Can't wait until someone replies to your question. -

Recent problem: clients are losing connection to AMS 5.0.1
For the past week, since Oct 14, we've been having issues with clients losing connection to our AMS application. We have online classes that include a chat room and sometimes an audio stream from the instructor. This application and its server has been running stable for months... until last week.
One of our staff was connected to the app, getting everything set up for a class, and she started complaining of getting disconnected. I looked in the application logs and noticed that the application.onDisconnect was being triggered. However, the client didn't register that it had been disconnected for several seconds afterward. She let me know when she got the "Diconnected" message on her screen, which comes from the NetConnection.onStatus handler.
The only other sign of a problem is that in the server's core logs we started getting the following error when we checked bandwidth:
> Invalid command message data: unexpected bw response from client 000000001D670170
The client number changes frequently, so I'm guessing that this is first happening to one person and then another. We don't think that this bandwidth check is causing the disconnects because we rolled back to a previous version that didn't have it. The disconnects still happened after using the old version. What makes it frustrating is that it hasn't happened to anyone on the dev team, regardless of which network we've connected from. Also, the code hasn't changed on the client or the server, and to my knowledge, we're still using the same configs for months.
The AMS is v5.0.1, the client is written is AS2 and targets Flash Player 11.4.
The affected Flash Players reported are 15.0.0.152 and 15.0.0.189, in browsers IE, Firefox, and Chrome, but not all installations are affected.
Is there anything else I can look at to determine what the problem is? Does anybody have any insight as to what might be suddenly affecting our AMS app?
Many thanks,
NickYes, we came to the same conclusion about the unexpected bw. We realize that it is not causing the issue, but I included it because it started happening at the same time and thought that they might be caused by the same issue.
We have been trying to come up with what changed to cause this, and aren't coming up with anything.
We have been on 5.0.1 for at least 5 months, no changes there.
We haven't updated the main.asc since 9/16.
The VM that runs our server is still the same, and AMS config files haven't been touched.
The client swf had a change 2 weeks ago, but we've reverted the change and are now using the old swf again.
The person who initially reported the problem was using the same computer that she's used many times to connect; she was going through her usual process to set up for the session.
You mentioned bad network, and that is another thing that I have been looking into, but our IT department says that we haven't seen any huge increase in bandwidth usage, and that everything looks to be within normal operating ranges
If there are any other points that you can think of that I could check for changes, I'm open to suggestions. This problem has been ongoing for 6 days, and I have been searching for answers since it started. -
A few months ago I purchased a WRE54G range expander. After some initial setup issues, it worked great until a couple of days ago. The expander stopped working and seemed to have reset itself. After a couple of conversations with tech support, the range expander finally had connectivity, however, I am now continuously losing the connection. I have downloaded the latest firmware for the expander and my WRT54GS modem, I have changed settings, turned my beacon interval down to 50, and am still losing connection. Does anyone have any other ideas of what I could try, or have a had similar problem that they were able to resolve? I would appreciate any help anyone can provide me with.
did u try a firmware upgrade on the expander too ?? if not , then give it a try .. try wireless channel - either 1 or 11 , RTS and Fragmentation threshold - 2304

Mac Mini (late 2012) Ethernet Losing Connection
Problem: Throughout the day, my Mac Mini loses it's ethernet connection for several seconds. Using iStat Menus the network tab shows that the ethernet connection is "Yellow" for "Not Connected" and I don't have an IP from my router. The same thing is reflected within System Preferences -> Network. This only lasts several seconds, but if I am streaming something or trying to stream a large file across my private network it can cause issues and be rather annoying.
I've already confirmed that it is not a router issue or a port/switch issue. I've tried different ports and rebooted the router several times and even updated the router firmware, regardless the Mac still occasionally drops connection. No other computer on the network including a Macbook Pro exhibits this behavior, it is only this Mac Mini that is doing it.
All my Ethernet settings are automatic, and I've tried setting everything to manual as well to no avail. The computer isn't over heating, temps range anywhere from 40C to 75C underload.
I am not sure what is causing this. I haven't run into this problem before and it JUST started recently.
Anyone have any ideas? Any solution? Any additional steps I can test for trouble shooting? My Mac is all updated as well.
Router I am using is ASUS RT-N56U with a Trendnet 5-port switch.Hello, might try this...

Possible fix for OS X 10.5.7, losing connection after sleep, restart
Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
=============================================
- After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
- Losing Internet connection after sleep, restart, cold reboot.
Possible Fix:
1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
b)Test to make sure you can connect to a web page.
c)Go to sleep & wake up.
d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
a)Check to make sure you can connect to a web page.
4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
5.Restart computer. Test a web page.
6.Shut down & Start computer. Test a web page.
7.When everything is working fine, you can delete the extra location that you created in step #1.
8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
(Removed link because of the way Flash drives the Canon site).
It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.

I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

Connecting several SG300 for failsafe
Not quite sure what will be best practise for me here:
3 x SG300-28
1 x SG300-10MP
Placed in 3 locations
1:
1 x SG300-28
2:
2 x SG300-28
3:
1 x SG300-10MP
I have 4 lines between locations 1 and 2, and 2 lines between locations 2 and 3
My idear was to use the 4 lines from location 1 and split them 2 and 2 on the switches in location 2
Between the two switches on location two I plan on have a 4 port LAG.
The 2 lines from location 3 I planned on split between the two switches on location 2
What I am uncertain about is STP, LAG's and how to get the best failsafe setup.
Any help would be appreciated greatly.Looks like I managed to get it working my self.
Used the idear I mentioned and here's the setup:
Location 1:
1xSG300-28
Switch setup with 2 LAG's each including 2 ports
Location 2:
2xSG300-28
Each Switch set up with a 4-port LAG as "stack" between the two.
Each Switch set up with a 2-port LAG connected to the Switch on Location 1
Location 3:
1xSG300-10MP
Switch connected with one line to each of the Switches on location 2
So far the setup is working as a charm.
