I have a switch containing 48 connections. I have a patch panel that links to lots of access points in my building. One access point was not connected but needed to be but I didn't have any spare switch ports. I therefore reconnected switch 23 from one position (and thus one access point) to another position on the patch panel. Everything worked fine and this new location had network and internet access. Then however a few weeks later I had to change it back so i changed the connection of port 23 to the old position on the patch panel. When i did so port 23 showed a red light and then no light. Later I had to change it back to the other location but when i did so port 23 now shows no light whatsoever. It's as if the connection port just stopped working. Now both the old and new access point locations have no connection and I can't understand why.I tried rebooting the server but no luck. I tried connecting that access point through the patch panel to a different connection port but still no luck.
I have setup a Cisco SR520W and everything appears to be working. After a few hours, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device.
If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my the modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again.
Here is my config file:
Building configuration... Current configuration : 17830 bytes!version 12.4no service padservice tcp-keepalives-inservice tcp-keepalives-outservice timestamps debug datetime msecservice

I have a cisco 6509 switch in which i have 2 SUPs. I am using 3 Qty. of WS-X6748-GE-TX in the same switch. First 24 ports of module 1 and are not working. I replace the faulty moldule with the working one but now the new (good) module's first 12 ports stopped working. But when I insert the good card (the replaced one with the faulty) in other chassis it works fine.
This has been happening repeatedly time to time! we just replace the part! But now it has come to trouble us again.It happening only in one module like 6 to 10 ports wont work.
we run IOS cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin will there be any bug in it?
I just upgraded to an E4200 from a D-Link DIR-655. I cannot seem to get my desktop to connect to the E4200 at 1 GBS. My adapter is set to "auto negotiate" but will only connect at 100 MBS. If I try forcing the adapter setting to 1 GBS, it never connects. I can swap out my E4200 with the DIR-655 and it will connect at 1 GBS just fine. I am using a CAT 5E cable. Is there something I'm missing here or is the E4200 just more finicky than the the DIR-655?
I am running a Linksys Wireless G 2.4 GHz Broadband Router Model WRT54G. I am unable to open any ports. I upgraded to the latest firmware yesterday but still am unable to open any ports. I even turned off my Symantec Internet Security Suite Firewall but still am unable to open any ports.
I am trying to test the gigabit ports on a Cisco 2950 switch. 1000Base-SX. I have the internet or dhcp server connected to port 24 on the first switch and my pc hooked up to the (any) port on the second switch. Both switchs are connected with a fiberoptic cable with MTRJ connectors on either side.
Now when I use gi0/2 on both switchs all works fine. I get a dhcp address from the router on the other end of the first switch. but when ever I include gi0/1 on either end of the fiber optic cable neither of the ports will initialize (neither of the leds above the ports light up). I have deleted all the config files before booting up the switchs so they should have a default blank configuration.
When looking at the Http web page for the switch I dont see any issues with the port. what can I do to make sure these ports are working or can be configured?
I will not be able to post back any more information about the switch until next tuesday. Im off till then.
I have two switches, WS-3750-24PS-S connected in two cabs via fiber. Patch panels at both ends with patch leads. Used tester to confirm end to end fiber connectivity. When plugged in, one switch lights up the other does nothing.
same at both ends. Tried both GI ports same result. swapped transceivers over and the same result, (one switch lit one not - the same switch in both cases). put both transceiver in each switch, (gi0/1-0/2 in a single switch). on the one that lights up in the original scenario we get link on both ports and they come up, on the other nothing happens. shut down both ports on the malfunctioning switch and no shut them, no change.
Show transceivers doesn't show transceivers on the malfunctioning switch, and no attempt is made to bring the ports up if the fiber is removed and replaced.
it is almost as though the two gb ports are kaput. Anything else I can try?
I've lost connectivity with all but one of the ethernet ports on my E4200 router. My desktop PC was connected to Port 1 but stopped working. Network troubleshooting via my Windows 7 Dell 8300 said I was not connected and to check the cable. I did that with several different cables and tried the usual router and modem reset. Only through trial and error did I find that I could connect to port 4 which is why I am able to write this post. What could have changed to disable ports 1-3 and can I get them working again? No issues with wireless connectivity.
I've created some port forwards from my public IP (Dialer0) to our private LAN but only the 25565 port forward works. I've even added an any statement to the Nat source list Homenet_NAT. Full config attached. My Cisco router is an 877W. [Code]
Why is loop-back only working on ports forwarded in the Virtual Server section and not Port Forwarding or even DMZ? I have seen a post about loop-back on the DIR-655 from a while ago that had said to disable SPI and change NAT Endpoint to independent, I have done this and loop-back still doesn't work.
I have a Cisco Catalyst 4507R+E (with Sup7-E) and two blades; one WS-X4748-RJ45V+E and one WS-X4648-RJ45-E.
When I connect a device to a port on the WS-X4748-RJ45V+E blade the port will not come up, show interface shows the status as "notconnect". When I connect the same device to the WS-X4648-RJ45-E blade the interface comes up.
The WS-X4748-RJ45V+E blade seems to have initialised okay, it appears in the output of "show module" as OK.
I get exactly the same effect on a second, identically configured Catalyst 4507R+E.
The software version is IOS XE 3.1.0SG, which according to the release notes supports the WS-X4748-RJ45V+E blade
We have an ASA 5505. 5505 comes with two default vlans 1&2 with each of them marked as inside & outside respectively.My query is , if i do not want to use vlans on 5505 and only want to use the Ethernet ports as pure physical layer 3 ports, is it possible?i.e. i want to assign a layer 3 ip address on eth0/0 and eth0/1 and make them as the inside & outside interfaces rather than vlans. is it possible to do away with vlans in 5505 & will it work otherwise?
Is there a way to associate spare firewall ports with another port that is being used..For example...int gi 0/2 is being used currently for my web dmz. Its ip is 192.168.10.1..Is there a way for me to associate gi 0/3 with the same layer 2 as gi 0/2 ?
In my webdmz I use 2 ACE 4710 proxys in FT mode. I used a layer 2 switch to connect firewall and proxys together.
I would like to eliminate this switch if possible..and connect both 4710's (layer 2) direct to firewall.If I could make gi0/2 - 4 part of the same vlan, then I would be good to go.
How many of the 881 switch interface ports can be used as router ports, have used the 877 etc where i can use 2 but need a low cost router that supports 3 for routing. (needs to be physical ports)
One of techs accidentally connected two access ports from different switches together. Since then, LMS is alerting them as being Link ports down. I tried to default the config and set them to access ports without any success. what I should do in LMS to recognize them as access ports?
XP Home edition, went to tools can't find working off line or working online to make sure off line is not checked so I can get on line DSL Verizon , Wireless router, wireless switch in on, on the cpu
A few days ago my internet suddenly stopped working. I plugged in the ethernet cord and everything worked fine. Checking the properties in the device manager showed the device was working properly, I also tried resetting it to make sure it was enabled but it did not work.
Upon troubleshooting, the "Windows Network Diagnostic" said the problems was that the Wireless adapter was not turned on. Using the switch on the front of the laptop as well as the function keys does nothing. Usually a graphic pops up showing if the WiFi is on or off, changinging transparent to show the WiFi is disabled. Now when I turn the switch on it always appears transparent, effectively going from off to off
So I know the computer reads both the function keys and the switch on the front but both methods never actually turns the adapter on. I just finished a system restore and nothing has changed
Today, while surfing the web my internet connection on my PC just randomly shuts off. I go check on my laptop and its normal. My WiFi says that I am connected to an Unidentified network with no internet access. So i got frustrated and checked all the forums and nothing seemed to work. So i restored my computer to factory settings and I still got this problem. Does this mean my Wifi Card is bad? Is it a virus? I can see other networks fine but i just cant connect to mine!
if i have four LAN ports on my modem+router , three of which are already occupied and i wish to add another three PCs to the same network, what hardware should i add to the fourth LAN RJ45 port so as to attach the other three PCs too.
Each of these has Windows 7, Avast! Anti-VirusToday I was working on a website on PC#1. When I attempted to upload the files via FTP, the connection failed repeatedly. When I went onto PC#2 it worked first time.I also tried to launch World of Warcraft on PC#1, this failed. It worked first time on PC#2.Websites work fine, so port 80 appears to be okay.I have reset my router to factory settings. ipconfig /release /renear /flushdns all made no difference.
How can I allow all ports to be open? I don't really want my 1811 to block any traffic. I tried the command access-list 1 permit any which allows me to surf the internet, but when I check my web server, and port 3389 (Remote desktop) on yougetsignal.com it says those ports are blocked.
I have seen several cases where ISP's block traffic on both UDP and TCP ports 135-139 even in core firewalls. Port 135 should be Microsoft EPMAP service and ports 136-139 should be NetBIOS services. However, why do ISP's sometimes block traffic on those ports?
I was told i need to open certain ports to certain IP's,what ports need to be opened to what IP's for the folowing game as im close to giving up.The games are as follows - Call of Duty 4, Counter Strike 1.6 and Source, Warcraft III, and StarCraft 2
I have a single physical machine A (Windows XP). On A, I have 3 virtual machines (A1,A2,A3) If a want to communicate with port 4444 on virtual machine A1, can communicate to the same port 4444 on machine A2, All the VMs below exist on the same physical machine.
I have opened the ports up on my Virgin Super Hub, and everything else in my house connected to this network can access the ports which I've opened, however just on this PC, I can't seem to open them, I've tried closing my firewall, and that didn't work either.
I had a DI 604 router and I couldn't forward ports, someone told me to buy a new router because my modem (TM602G) doesn't have a built-in router and can't be blocking it so I bought a DIR 601 with wireless and I still have the problem.I don't have any firewalls.
