Cisco WAN :: 2610 Connecting 2 Routers With Only Fast Ethernet

Apr 28, 2013

I have a home lab.  I am trying to connect a 1710 to a 2610 with just using the fast ethernet ports.  I understand that serial connections and t1 csu/dsu connections use clocking, etc.  How can I configure FA ports to do the same AND be routable?

Cisco Switching/Routing :: 2610 Router What Speed Is Built In Ethernet Port

Oct 23, 2011

I have a 2610 router. How can I tell if the built-in ethernet port is only a 10BASE-T or if it's a 10/100 port?  Is there a "Show" command to give me this information or did it only come one way?  I have found conflicting information on this :-(  If it's only 10BASE-T, can I upgrade it to 10/100?

Connecting Multiple Routers Via Ethernet Cable For Range?

Dec 20, 2012

Although I haven't looked through all the forum topics I couldn't find anything very similar to my situation. I have a rather large house and my modem/router (Netgear DGND3300 v2 due to DSL) is in the very corner. Given this most of the opposite corner of my house gets either poor or no connection; however, I do have an ethernet cable run across the house through the basement to my home theatre setup. This is where I encounter another problem, I need multiple devices to be connected via ethernet and I also need to have wireless in that same area. In my mind I picture myself connecting a second router to this ethernet cable through which I could have wired connections to all my devices, and a second router broadcasting wirelessly. I'm familiar with some types of wireless bridging, but I'd rather use more of a wired bridge concept if possible, but I've never really seen something like this. The question is, is this possible? Or, what is another possible way to achieve the same results? The only other thing I can think of is to run an ethernet hub from the original wired connection to my home theatre so I can connect multiple ethernet devices and run a separate wireless extender or something, but this just seems pricy.

Gigabit Mixed With Fast Ethernet?

Oct 7, 2011

I 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.

Routers / Switches :: Internet Dies When Connecting Ethernet Cable?

Oct 25, 2012

I've got a Cisco DPC3825 modem that I also use as a wifi router. Conntected to it I have 4 eithernet cables:

1. From PC to Router

2. From another PC to router

3. From TV to router

4. From a Dlink Powerline Adapter to Router.It took me a while to figure this out but when I unplug all the eithernet cables and plug back in #1 and #2 (from above) the internet works. When I plug back in #3 and #4, the internet dies. Meaning, I am connected to the network but not the internet. I've reset the modem, changed SSID and restarted the PC many times but still can't figure out this issue.

Cisco Switching/Routing :: Getting Second Fast Ethernet On 2620xm?

Aug 11, 2008

I am having a heck of a time finding information on this.  I have a 2620xm router that only has one Ethernet port on it.  Is there an expansion I can get that allows me another Ethernet port. I have thus far assumed that all of the WIC cards won't allow me to attach to an Ethernet LAN.

Cisco Wireless :: AP 1240AG Series Fast Ethernet Cannot Up

Apr 18, 2012

how is the IP configuration for this Fast Ethernet F0.
 
This is because usually we only assign IP to the BVI interface. Is it after that, the Fast Ethernet F0 automatically also be assigned the same IP?
 
As such, when goto the Fast Ethernet F0 by CLI, by using no shut then this will Enable the Fast Ethernet Port?

Cisco WAN :: 2811 - NM 2FE-2W Card And Fast Ethernet Interfaces

May 18, 2011

I had a question regarding the Cisco 2811. I tried fitting an NM 2FE-2W card and the fast Ethernet interfaces of the module never get recognized. Is there a special command to enable it or isn't the module supported at all by the router. If not , is there a way to have the router possess more than the 2 Fast Ethernet interfaces it already has? Let me know if any more info is needed from my end.
 
Another question I have out of curiosity. Is it possible to make the controller T1 port of a VWIC 1MFT-T1 or a VWIC 2MFT-T1 act as a fast Ethernet.

Is there a keyword that we use under the interface to specify that it is purely management?
 
We need to assure that the subnet and any node on that subnet is not shared with the default routing table.
 
how do we set the gateway for the management interface if the node we are sourcing the ssh session from is on a different private subnet?

Cisco WAN :: Fast Ethernet Interface Being Take Down With Burst Of Traffic 2800

Jan 12, 2011

It is a single router with dual ISPs. It is a 2800 and there is failover configured. I have implemented object tracking and the feature works great except that lately, whenever there is a lot of traffic coming perhaps from the internal users, we start getting intermittent outages.
 
I have gone deep into looking into this problem and have determined that our ISP#1 does not have any problems. What I think is happening is that whenever the router receives a lot of packets (30-40 users on the internal network) destined to the outside, the router CPU maybe gets too busy and the router then believes that the objects are no longer reachable and it triggers a failover which causes the router to re-direct traffic to the ISP#2. Then, because these are just quick burst of traffic, in the next 30 to 45 seconds after the router re-directed the traffic to ISP#2, the router object tracking engine detects that the objects are now again reachable and this then causes the router to re-direct all traffic back to ISP#1.
 
This cycle then continues all day on how to prevent this.

Is there a way to perhaps tell the router to completely shut down the interface facing ISP#1 whenever there is a hicup and to keep it shutdown for at least 8 hours? This way I can prevent the router from going crazy.
 
Or is there a way to perhaps prevent this at the internal (LAN)  interface? Are there some metrics like QoS that I can implement on the internal Fast Ethernet Interface to prevent the burst of traffic from eating up the CPU?

Cisco :: Setup P2p Link Between L2 Fast Ethernet Module (within A 2900) To 6506

Oct 14, 2012

Trying to set-up a p2p link between a L2 fast ethenet module (within a 2900) to a 6506.Have created a subinterface SVI on the 2900 and put the fast ethernet port in the respective VLAN. However on 6506, am I correct in thinking I can do a no switchport and just create a L3 interface? Do I need to put the 6506 in the same vlan and the fast ethernet module and create a L3 SVI on it? As it's not a trunk port between the 6506 and the fastethernet module, the packets won't be tagged?

D-Link DES-105 Fast Ethernet Switch - Signal Constantly Being Dropped

Jul 23, 2012

I'm watching a video streamed from my laptop and the signal is constantly being dropped. I suspect the D-Link DES-105. I have another Ethernet switch on the system as well but it is a Gigabit unmanaged switch from D-Link and has worked well with video streams. I've removed the DES 105 from the circuit and videos play fine. Should I dump to DES-105 for another Gigabit switch? SOme say I have a bad cable somewhere but I have tested all and have not found a problem.

Asus RT N16 - Would Fast Ethernet Switch Slow Down Gigabit Networking

Nov 4, 2011

I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.

Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?

Belkin F7D4301 - Router Has Slow Wireless Speeds But Fast Ethernet Speeds

May 19, 2013

My Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.

My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.

I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.

Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?

Belkin Routers :: N150 Fast Wired / Ultra Slow Wireless

Mar 5, 2013

I bought my own modem, a Motorolla Extreme something or other, is a DOCSIS 3.0. My router is a Belkin N150. When I plug my desktop computer directly into the router, I get speeds upwards of 50Mbps. The wireless, however, gets about 0.15Mbps download, but as much as 12Mbps upload.

I know it's not computer specific, because I plugged my laptop directly into the modem and got the full speed. AND I put a wireless adaptor on the desktop and got the slower speeds.I live in a densely populated area and there are 27 other (visible) wireless networks available (all locked, unfortunately. Otherwise I wouldn't be in this situation in the first place). So I tried every channel, doing a speedtest with each, and I got almost identical results each time: 0.12-0.17Mbps download, 11-13Mbps upload. I can't imagine that getting only 0.15Mbps could be a result of a channel being clogged, but I tried it anyway;
