We are looking for a solution to avoid VPNs to encrypt data between HQ and Bldgs (point-to-multipoint) Gigabit fiber(untrusted media).Is there any cisco's product providing layer2 encryption over Giga fiber?The HQ has a 6509s and remote bldgs have mixed of 3750s,4500s in trunks.

I have an Ethernet Loopback Plug (4 Pairs) made and trying to test the Gigabit Interface on a 3845 Router with a fail result. The interface will show up/up only if I set the interface to 100M/Full Duplex when I plug-in the Ethernet Loopback Plug (4 Pairs). I don't see this Gigabit Interface @ 3845 router has any option to set it to internal or external loopback.
View 2 Replies View RelatedWe have a situation where we need to encrypt the traffic on a Layer 2 V LAN. We have a Cisco Switch on each side but the fiber it runs over is leased and encryption (AES256 minimum) is required on a leased line. We have 2 ASA5505s that we could use on each side. Not sure what would be the best setup for this scenario (Site to Site). Or is there something better than using 2 ASAs on each side?
View 14 Replies View RelatedI am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.

View 1 Replies View RelatedI have a WLC 3750 with 41 APs. We use Web Authentication with the combination of a layer 2 security feature (WPA/WPA2 with PSK). With this combination some clients have the problem that they get deauthenticated and have to authenticate again while being in an active session. For testing I disabled the layer 2 security feature i.e. I set it to "none" but I left the Web Authentication enabled. With these settings none of the clients has any more problems with getting deauthenticated. They stay online for the entire session.

Are there any options for RJ-45 ones on ASR1000s?
There is an option for the 2 port where one can mix and match SFPs and RJ45 but I was looking for something which is RJ45 only.Are there any options for them available.I know I could get something with FastEthernet type but was looking for the GigabitEthernet type.

View 4 Replies View RelatedI currently have 2 PCs that are directly connected to each other via a 1Gbs Cat6 connection.I don't currently have a 1Gbs router so what I am doing right now is unhooking this connection and reconnecting both machines to my router when I need internet access. I have ordered some USB Wi-Fi adapters so I can have both machines access the internet that way whilst still use FTP between them on the 1Gbs line.If I were to scrap that idea and get a 1Gbs hub, connect both PCs straight into that, and then also connect the hub to my 100mbits router, would the 2 computers be able to communicate with each other at 1Gbs and then talk to the router at 100mbits, or would the whole network run at 100mbits.I don't really want to have to shell out on a 1Gbs router as I don't need anything else on the network to run at that speed.

View 3 Replies View RelatedSo my old router needed replacement and my dad bought a Netgear gigabit ethernet switch instead of a router. It said that it gets 1Gbps when I look inside the local area connection speed. The problem was we tried to use it like a router but only 2 computers could connect to the internet at one time but it was indeed noticeably faster when it came to video streaming speed. We since returned it and bought a Netgear N600 router that says the speed is 300mbps but like my old router it shows the speed is actually 100mbps and the streaming is good for the most part but every now and then slows down. Would using the ethernet switch with our new router work with streaming speeds and connection stability and of course let more computers connect and also use the routers wireless.
View 13 Replies View RelatedI have the following problem. I bought two TP-LINK TG-3269 gigabit cards, placed them in two computers and connected them directly. On my Ubuntu system I used iperf tool and measured only 95 Mbit/s. It wont go any faster, I tried many times with different settings.
The indicator lamp shows 1000 Mbit/s.
But I currently have a Linksys E3200 I bought in a moment of weakness after an evening of being pissed off at bricking my old WRT610N. (soft bricked, but I'm beyond screwing with it)
There's nothing *wrong* with it, but I am interested in something that either comes preinstalled with DD-WRT, or is well supported (ie easy to install on) by DD-WRT. I plan on selling the E3200 once I find something to replace it.
My requirements:
-Gigabit
-5 GHz (I have a file server/HTPC; I don't want to be limited to gigabit ethernet)
-$150 or less (I know $150 is high, but I figure I'll get close to that for the E3200)
I am moving into an apartment thereafter. I have an HTPC in use, a personal computer for gaming/processing, and my fiancee has an Apple Macbook Pro that she uses quite often. I have an HDHomeRun Dual (2 tuners) for streaming OTA/QSM cable over the network (the HDHomeRun plugs into the network, not a computer). I also have a TV and Blu-Ray player that have ethernet ports.
Currently I use Verizon Fios and their Actiontec MI424WR router, which to my knowledge has gigabet ethernet. When I move I will probably be saddled with Comcast Xfinity Internet, which will supply a cable modem if I want, but no router. The only router I currently own is a Zyxel NBG-419N, which has only 100/10 ethernet ports. My current computers all have gigabit ethernet. For the home theatre components and my HTPC, I plan to pick up a network switch with gigabit ethernet. So my questions are:
1. If I use the Zyxel and the Comcast cable modem, would I be throttling my network speed at the router? I would hate to choke my speed just because one component does not have gigabit ethernet.
2. If I were to upgrade to, say, an Asus RT-N56U, would that make a huge difference on network browsing and throughput speeds?
3. Finally, what kind of cable is needed to maximize discernible speed increase? Cat5, Cat5e, or Cat6?
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.
Ports are as follows:
interface GigabitEthernet1/0/2
switchport trunk encapsulation dot1q
switchport mode trunk
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?
