We have a wan serial connection connected to cisco router 1750, and we want to upgrade the serial connection to ethernet but we haven't any additional ethernet interface on the router. Is there any converter from ethernet to serial?

View 6 Replies View RelatedI have a 1941 router with the security licence. I am setting up both a T1 wic that connects to my enterprise MPLS cloud and one of the two gig interfaces that will connect to my home office through a VPN tunnel to a ASA 5520. I have tried multiple solutions though my gues is that I am making this WAY more difficult than it needs to be. What I am trying to create is a primary on the serial interface and then a failover through the VPN.So far, I have tried to:
-Track the serial interface and then set the default route, based on the tracking
-Create an IP SLA to echo the gateway of the serial interface to change the routing
-Started to create HSRP between the two interfaces though I could not figure out if / how a standby could be put into a sub-interface on the serial
The SLA seems to be working somewhat. The problem is that it is not transparent and sometimes even needs me to clear the VPN tunnel to get things back to smoothly through the serial interface. [code]
I know serial interfaces are called that because they put bits on the wire serially - i.e. one bit at a time. If that's the case for serial interfaces, how do other kinds of interfaces, such as Ethernet interfaces, put bits on the wire? Do they somehow put more than one bit on the wire at a time? I assume it's a faster process, but how so?
View 4 Replies View RelatedI'm looking for a good managed (i.e. a unit with stats and troubleshooting capabilities) fiber-to-copper media converter. I know there's plenty of "dumb" media converter choices out there, but was hoping to get one that has a console conn or the like to troubleshoot any possible issues. I'm converting between 50nm multi-mode fiber with an SC connector to 1000-bT copper.

I have a problem with my vpn concentrator. I cannot access it through console, I have tried every baud rate that is available on my SecureCrt but it won't display anything. At first, I thought that my console cable is defective but I was able to access a WLC via console cable together with the rj45 to db9 converter. I also tried connecting the vpn concentrator to a switch and enable the cdp in the switch but the "show cdp neighbor" can't detect or display the vpn concentrator even if the interface status is "up up". Is it safe to say that the VPN concentrator is already broken?

Can not connect my Dell Inspiron 1750 to wireless internet. Have 3 other devices that use my wireless with no problems.
It used to work but began to fail sporadically. Has not worked for a year.
checked for updates. Drivers supposedly are up to date.
My Inspiron 1750 runs Window 7 with Dell wireless 1397 WLAN mini card installed. It suddenly now cannot get internet nor network connection. The troubleshooting says WIRELESS CAPABILITY TURNED OFF. How can I turn it on and keep it always on?

The USB Bluetooth device is connected successfully and the Bose Speaker shows on the system but with errors. When I try to install drivers for this I am unsuccessful and also using the manufacturers SW I cannot load through the SW
Is there a Dell Driver that I can load that will aid the connection?
why this is erroring as I do not have any issues connecting my phone to either the Speaker or the Laptop?
having recently installed the correct bluetooth module inside our dell insprin1750, all the drivers loaded fine and it said all installed ok, I can see all items in the control panel/hardware list as all ok... not highlighted or anything so assume its all ok. When I click on the bluetooth icon down on the bottom is pops up and says bluetooth is working but not visable to other devices click here to change... which I do, then the problem.... nothing happens after that !
I am unable to add any devices to bluetooth list despite it saying its working ok in hardware properties etc.
My last resort is to restore pc to factory state via re-install of windows 7 but I do not really want to go down this route if at all possible.... I have tried restore to no avail.

I spoke to a local Cisco supplyer who recomended the above switch and an Allied Telesis Media converter.
I cannot seem to get the Allied Telesis unit to connect to the cisco switch.I have proved the fibre link by connecting 2 AT Media converters over the fibre.Do I have to enable something on the Catalyst switch or is the AT Media converter not compatible with the Catalyst switch?

To do that I would like to be able to sniff the traffic traversing our 7k. However, as the 7k doesn't support remote span we have to span locally. This means that I have to connect a pc to the Nexus and sent the span output to that port. However, our 7K is only equipped with N7K-M108X2-12L modules, which contains X2 10G ports. I found the CVR-X2-SFP10G X2 to SFP+ convertor module, but I wonder whether this supports a 1G copper SFP. If it doesn't it would be wasteful to buy one. On the page concerning the module I only found 10G fiber sfp's which are supported.
I have a 4506-E with the following supervisor module:WS-X45-SUP6-E
It currently has 2 TwinGig converter modules installed. I want to upgrade the 2 1Gb connections to 2 10Gb connections. First I took out the converter modules and installed 2 X2-10Gb-SR's, but it didnt recognize ("No X2 GBIC")???
Then, I put the converter module back in and put two SFP-10GB-SR's in them, but they don't recognize either...???? I"m running IOS
12.2(54)SG1.
According to the 10Gb matrix, they should work:

I have made a routed port on 3560G Switch and defined a pool 172.28.4.62 255.255.255.192 and connected to E1 converter RAD (4E1 to 4 FE) the E1 media is through Microwave on the other end same E1 converter is connected through layer 2 switch and defined a pool as of routed port configured in 3560G switch.
The port is generating lot of giants and after a while it also distrubs other routes ( Port1 to Port 16), configured with Vlan11 and port 22 as routed port.I have checked the routed port through wireshark the maximum frame size is 1514 and configured the MTU to 1514, giants are not showing any more but after 10 to 12 hours switch gets hang. Either to shut the port or to reload the switch to get switch and other layer routes to be normal.
I have checked speed and duplex settings same as E1 converter. Full duplex. 100 Speed. Why switch is not behaving normal. If I shutdown the routed port it is normal.
