Cisco Switches :: SF 102-24 MGBSX1 Doesn't Show Any Link Lights Or Traffic
Jul 28, 2011
I just purchased a Cisco SF 102-24 unmanaged 100 series swith with a MGBSX1 mini-Gbic converter. My goal is to connect this to a building that is connected with a Black Box LH1706A-ST media converter that has 100mb ST fiber connections. In my testing the Black Box shows both a Fiber link and RJ45 port link at 100mb, but the MGBSX1 does not show any link lights or traffic. So a computer connected to the Cisco switch is not able to communicate over the fiber connection.
Can the MGBSX1 be connected to a media converter that only has 10/100 ST fiber connectors?

I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

I am running a DIR-825 I believe one of the original's no updates or anything. I run it mixed mode. The 2.4 shows up and I can connect to but the 5 ghz (n) speed says it's enabled but I can never see it when I scan on any of my wireless n products (laptops and other computers). Dlink support told me to change to mixed mode g and n. I was running it in mixed mode (a, g and n). D link told me to change to mixed mode g and n and to make sure they stay on channel 6 and 11. Is this correct. Which firmware should I upgrade to and is there any easy way to do this?

I have had my DIR 615 router for about 6 months, and have had no problems. I have a notebook (Sony Vaio) and I also have a Blue-Ray Player and my DirecTV DVR connected by ethernet. Starting a few days ago I was having connectivity issues. At first I could see the network on my Vaio, but the Internet kept coming and going.I did some troubleshooting on the adapter and that seemed to work. Now I am having an issue where every 2 hours or so the wireless drops and the network disappears from the list of available connections on my notebook. I have had my netbook on (connected wireless) and the issues are replicated on that system.
Both of my wired devices do not see any interruption in connectivity. Living in an apartment complex I suspected interference and indeed there are a ton of other networks in range (as per inSSIDer 2.0). As there is no channel that is clearly open, I have set my router to auto channel scan. I also have tried some of the steps outlined in other threads. The thing I am noticing is that when the network connection drops my network (which has a unique name) doesn't even show up on inSSIDer, it just disappears. When working, my network is consistantly in the -25 range on inSIDDer.I should point out also that my notebook is a mere 8 feet from the router, and there are no obstructions.

The router is not showing my external hard drive in the usb settings. The Hard drive is a seagate 7200rpm 1.5tb. The hard drive works just fine when plugged into my computer. I have tried NTFS and EXFAT. My 2gb usb drive in FAT32 shows up just fine. The external has its own power supply. Is there anything I am missing that would cause it to not work?

we have three separated network segments going to one Cisco 3750 switch all is L2 .. from this switch is 100 mbit uplink.we need to apply some Qos mechanism not to saturate line by traffic from one network.. Configuration from various reason CANNOT be done on switch where 100Mbit line is terminated.. so all must be done on SW1,2,3..Correct me if iam wrond but as switches doesnt see traffic from other network iam affraid only think we can do is limit bandwidth on links going into SW1,2,3 to 33 Mbit.I found commad srr-queue bandwidth limit.But links going to SWs are 1Gbit so if i force bandwidth to 10% (minimum what command allows) its 100 Mbit..If I force speed on those links to 100Mbit and than apply srr-queue bandwidth limit to 30% doest it work.??. Will srr-queue bandwidth limit speed to 30Mbit?? Or srr-queue bandwidth limit is calculated from maxim speed of interface?

like today randomly my internet went down. And then everything changed back to its original like my SSID from Netcom it changed back to wireless and everything was default and also the PPP was off so i wasn't able to connect to the internet. So i went to my router setup page on the internet or whatever and turned it back on. So now like the internet on my computer which has a cable to the router works but the wireless internet doesn't work for my laptop nor ipod. I can see the connection on the laptop and ipod but when i try to connect it keeps saying that it is unable to connect.

I picked up a second hand NETGEAR FS750T switch today for very little as the previous owner said it had stopped working.
After powering it up, there is a small noise for about three seconds. All the lights above the 10/100 ports are solid green and I can't access the web interface when connecting it up to my computer.
What could the problem be? I've heard others with different switch models reporting that all the lights are flashing and replacing the capacitors fixes them.
I've tried the reset and factory reset buttons. The reset just puts all the lights off for the duration of holding it and the factory reset appears to do nothing.
edit: when I turn it on, all the lights and the sound starts immediately. After two seconds, the lights go out. After three seconds, the sound stops and the lights return.

I have several SGE2010P switches connected in a stack. They are working fine as a stack.
Question is - what traffic, besides stack control, is carried over the stacking links?
All unused ports are VLAN 1U. Ports in use belong to VLANs 100, 101, and 105.Since I cannot configure or see the stacking ports, I am unclear if any non-default VLAN traffic passes over those links between switches?

My previous setup was a ProSafe GS108 switch, 10/100 Dlink router/switch used only as a switch, and a DI-655 router/switch. With this setup, activity when I wasn't using any of my computers was zero. There would be no blinking activity lights.
I dumped the ProSafe and 10/100 switch, and use the DI-655 only for my internet uplink and wireless, and now have everything else plugged into a Cisco GS200 switch. There is activity now every two seconds. I presume this prevents the Green energy saving features from kicking in as the ports are in use.
What's the difference that's leading to all this activity that presumably wasn't there before?

Thinking back, about a month ago I updated the firmware (I can't check version at the moment). The switch has been working fine since then. Today I needed to move some power cables and the switch lost power. Now ALL of the LED lights are flashing green and I can't access the switch. I've tried setting a static IP on my laptop to 192.168.1.20, mask 255.255.255.0, and accessing the switch on 192.168.1.254, but there's no response. I've tried holding in the reset button for at least 30 seconds while the switch is powered on, AND while powering it on. None of that has worked. Also when I first power it on, the system LED flashes orange very quickly for a second or so, then all of the LEDS start flashing green.

We recently installed 15 of these switches, and we're having a few odd, random network issues. But before I enumerate those issues, I have a simple question: are the connection lights on these switches *supposed* to blink rapidly? Or are they supposed to blink *normally*?On all other switches I've ever seen / worked on / worked around, when a cable is plugged into a port, the connection lights blink upon network activity. sometimes they blink a little faster when there's lots of activity, but mostly it's an almost lazy, random kind of blinking. When you look at a switch and every light on every port that's connected is blinking very rapidly, your first instinct is "No *wonder* nothing works around here!" and you find the port that's chattering and unplug it...all the blinkies go back to normal.Well, on the 15 switches we've installed, every light that's on blinks rapidly, as if there's an uncontrolled storm going on. Is that the "new norm"? Did I miss the memo, and there is nothing to be worried about here? Or are the rapidly blinking lights telling me there is, indeed, a problem?

Every once in a while when logging into Windows (7 Ultimate 32 bit) My PC decides it couldn't find a network connection, usually restarting the computer solved the problem, however now I have seemed to permanently be stuck on the "identifying" stage of my LAN connection. My mobo is an Asrock p67 extreme, the network adapter is a realtek pcie family card.Now I know it is not my modem since I can connect on my other PC in the living room, I verified this with a phone call to my ISP, they couldn't see my PC connected to the network but could see the other one.It is not the Ethernet cords, I switched them and even used a new one. I tried rolling back, installing updated and installing factory drivers for my network card, no change.
I tried turning off the PC, disconnected the power cord, discharged it, left everything off/ disconnected for 30 minutes and reattached, powered on, no change.I made sure my DHCP was on and that my PC was set to automatically retrieve IP/DNS.I even bought a new Ethernet card, installed it and I still can't connect, so its not the realtek card.I can't even access my modem using its UP address, 192.168.2.1 (Bell 2wire) but I can on my 2nd PC, it sees all other devices, PS3 /Smartphones but not my PC.

So, I happened to do CD recovery a day ago; *Due to forgetting Administrator password* and now my laptop seems to not be able to pick up any wireless connections when there usually is a ton. Also every time my laptop restarts it always loads saying "Preparing for first time use" Like I used the CD recovery again. which I didn't. I thought that maybe it has to do with the Drivers and such, though im not very tech fancy, so I wouldn't exactly know where to find the correct driver to install, and which to install.[code] Oh and lastly, I happened to notice on Driver manager, that on "other devices" there is a yellow exclamation point, on both of them: Intel(R) Centrino(R) Wireless-N + WiMAX 6150 and Network Controller.

I have an ASA 5585 in transparent mode, multi-context. It seems that the option to configure a BVI in one of the traffic contexts isn't there. In other words, while I see the option to configure a bridge group interface in the admin context, no such option comes up in the traffic context.

Im working for a client at the moment and I've had to setup a network printer for them, I've got 4 Windows 7 machines easily printing over the network to this printer that is connected wirelessly but they want one of there machines to use the scanning functionality of the printer.The scanner doesn't show up at all in the local network devices like the printer does and to be honest i don't really have any experience with scanning over a network to a windows 7 machine, but this printer does support scan to ftp so my idea is to setup a small ftp server on the windows 7 machine with a folder to stored scans on the desktop or something, then put the details of the server in to the printer making it as easy as possible for the customer to scan stuff and just get it from the folder on the desktop, i could also share this folder over the network for anyone to open and get a scan if needs be.

I put Win7 on a customed pc bought online. The motherboard has an Atheros L1 integrated NIC and I installed a Dlink dge530t NIC into a PCI slot. I know I have to disable the onboard nic but the installed card is not comming up either in Device manager or network connections. What gives? In the bios under integrated peripherals i did enable PnP OS.
