Cisco WAN :: Achievable Throughput On Shared - Parallel 100BASE-TX Downlinks
Oct 17, 2011
I'm trying to estimate the potential throughput I will be able to achieve on a network we are building. The core ring of the network will be composed of ruggedized industrial ethernet Cisco IE 3000-8TC-E, possibly each equipped with a IE 3000-8TM expansion module. We will be using 1000BASE-BX SFPs on the IE-3000s to form a 1Gbps backbone on a single fiber. The issue is that I want to establish branch connections out from each IE-3000 node on my ring to routers which can support 1Gbps, but I have no 1Gbps downlink ports available on my IE-3000's. Therefore, I was thinking of paralleling as many 100BASE-TX copper links from the IE-3000 to my routers, so as to emulate a 1Gbps link and achieve maximum throughput. Both sides will have 16x 100BASE-TX connections available... but what is the maximum number I can parallel together and what achievable real throughput can I assume given the innefficieny of paralleling multiple connections?

I have new contract for 100mbit instead of 30 and I am confussed a bit.
I have a tp-link 150mbps n router. wr740n model.
On pc I have wireless g adapter usb dongle. 5bars signal.
I can't get more than 22mbits on that pc via dongle. I know it is g and not n, but 54mbps should be achievable right ? If I connect my old notebook to a wall cable just by itself (ip of this notebook is registered with my isp) then i get about 94mbits, so the new internet IS working.
That new tplink 150mbps router is new and set correctly to my knowledge.

What is maximum achievable speed of my e1200v1? Latest firmware is installed. I am using Xfinity Blast (50/10). Wired, i get 52mbps, wireless only 25mbps.I have attempted reflash, WMM disable trick, channel 9 setting and disabling the wireless security completely. Normally, i have my laptop, Droid3 and iPod connect via wireles, but for the sake of achieving max speed, i disabled all but the laptop. wireless connection status displays speed: 144 mbits.

I'm a college professor and was assigned a new course called Distributed Operating Systems. I'ts new material for me. And in research for class I have found that several machines can be connected together to build a bigger computer like a supercomputer. How could I connect several PC's and make them work together like parallel computing, o something likea super computer?

Our ISP will give us a single drop with two public IP blocks - one primary, one secondary. I would like to configure and run 2 firewalls:
firewallA will have a public ip from primary interface
firewallB will have a public ip from secondary interface
I'm very new to networking, and trying to find out how I can do it. We have a cisco 2901 router.
I'm considering
connect the drop to the WAN side of a router (2901)
configure both the primary and secondary interfaces on the router
configure the router in bridge mode
assign the public ips to the firewalls and connect them to the LAN interfaces of the router
(I know I can use 1 firewall and configure both interfaces on it without the router, but I would like to know if the above setup will work).

Obviously you do not want your cat6 lines running too close to your power lines especially when in parallel. The question though is how close can it be without causing interference?In my situation the wall I want to connect my main router to has a power outlet in the middle of it which honestly is where I would have preferred my network ports. Will I be OK if I run my cat6 in the wall channel directly next to the channel that contains the power line? It would be a standard U.S. interior wall residential power line. I should be able to get from 12 to 24 inches of distance between my cat6 and power line while still keeping my network outlet in a semi-central location.

Currently my setup works fine except that I need another ethernet port.I have a E4200V2 with a HP laserjet 4000N printer connected via JetDirect ethernet and I am able to print with any of my devices.However, because I have need of another ethernet port, I am wondering if anybody has tried using a parallel to usb cable? The parallel side of the cable being connect to the printer and the usb side to the router.
Or if I really want that port made available, will I have to get some type of external print server?
I know that HP makes a JetDirect Card with a USB port, however, I don't want to spend the $80 on ebay to get a used one if a $10 new cable will work.

We have a 1841 setup with WAN and LAN subinterfaced(2 WAN connections, 1 internal VLANs) and I am recieving some pretty horrible throughput when traversing the router to the WAN.
I am receiving about 2 MBPS down but around 5 up.Currently there is a ACL on the WAN interface, and as well we are running NAT NVI. It is possible that this might have something to do with it, but I am not sure.
Most of the CPU is going to IP input however I cannot seem to determine the cause. One thing I am thinking is the overload for NVI is using a route-map. Could that cause it to process switch instead of fast/CEF switch?

My first wireless router, which I still have and works perfectly, was a DIR-601, A1, fw v1.00na. It has always been reliable and worked great, save for being a little weak on the signal range. Back when I got it I knew little about networking period, let alone wireless routers- so I never tweaked anything on it. Now it's almost 4 years later. Being a little more knowledgable, and my family creating A LOT more traffic on my network, I decided some upgrades were in order. First I called COX to upgrade my speed too, which led me to having to purchase a new Motorolla SB6121 modem- and everything was great. However, aside from the same old dead spots in my house, I was starting to realize the limitations of my 601 with regards to handling the traffic load. Since I never had an issue with my 601, I decided to stay loyal to D-Link. After, albeit, a small amount of research... I decided on the 655. It fit the budget, and I read some decent reviews on it regarding gaming. Plus, from what I've read, I didn't really see any benifit to justify a dual band router for what I do. Anyway, my new 655, B1, fw v2.05NA has solved all of my wireless issues and handles our traffic perfectly, except for one slight problem- my wired PS3. I have Cox ultimate, which here in Nevada is up to 150Mbps, and wired my laptop is getting 107Mbps download- pretty consistently with the 655, and around 100 with the 601. My PS3 on the other hand, went from 27 to 32Mbps wired with my 601, to only getting 8 to 15Mbps wired to the 655- and a lot of lag on certain online games. It seems that out of all of our devices, my PS3 is the only one that doesn't like the 655. I really hesitate to DMZ my PS because of the risks, but at this point I'm almost desperate enough to try anything. I hooked the 601 back up for now for the PS3 performance...but we are REALLY missing the wireless and traffic handling performance of the 655!!

When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?

I have a Cisco 881 (without wifi model) connected to a 100Mb unmanaged switch and a cable modem with a 120Mb down, 10Mb up connection. When I connect the modem directly to my laptop, I can reach the 120Mb/s down and 10Mb/s upload speed. When I connect the modem to the 881, the max download is about 30Mb/s. Upstream 10Mb is no problem. I've been trying to change the duplex and speed settings on the FastEthernet4 interface, but this has only a worsening effect. I should be able to get about 100Mb/s (since switch is only 100) right?

We have multiple sites that have either fiber 20mb d/u or cable 50/10 d/u. Recently we have upgraded our head end router to a 2921 security based router and noticed that no matter if we are sending or receiving the most we can push is 1.6Mb. I would expect this number to be at least 8Mb for uploading and at least 18mb for downloading from other sites.I have included parts of my config and screen shots of bandwidth usage for troubleshooting.

We've recently moved from using FiberChannel across an OC-48 between two data centers to GigabitEthernet. Data replication throughput has dropped from 700Mbps down to 45Mbps. The telco provider has demonstrated 1Gb throughput via UDP andTCP using T-Berts. However, when we connect two computers or servers, we do not get near the throughput performance.

The issue was about Cisco ASA5510 Sec Plus.2 Interfaces, LAN and DMZ.Both 1000 FD, no interface errors like CRC or something similar.If I start a data transfer (like FTP) or a data stream test (like Netperf), from DMZ to INSIDE I get a theoughput.If I start the same from INSIDE to DMZ (same hosts), i get a troughput almost ten times slower.If i do the same using netperf in UDP (not TCP) I get the same in both directions.

we have one OC-24 private line between our data centers. we are looking to get best throughput but we get max. avg throughput of 300Mbps with peaks of 800Mbps throughput. i.e. we transfered 2TB of data over this link and we got average throughput of 300Mbps with peaks of 800Mbps.
we should at least be getting 800Mbps throughput since we have OC-24 (1244Mbps) private line. we contacted our ISP but they said there isn't any problem in private line from ISP side. what can we do to increase average throughput?

Do some have some realistic performance numbers for a ASA 5505 on a mixed setup with local internet breakout and site to site vpn ( and don't tell me 150 mbps 3des throughput on a 100 mbps ethernet) - what can be expected in a live environment where we f.ex feed it with a 100 mbps internet connection - with a site to site vpn with f.ex 20 office workers running office on a remote terminalserver and mixed local internet breakout.

We currently are using 2811 router for internet Via IPSEC tunnel.Download speed is 30 Mbps and Upload speed is 6 Mbps.
But we are getting not more than 4 Mbps download speed. We did open Tac case and as per Tac 2811 router is not for 30 Mbps.Can any suggest proper model. We need 2 FastEthernet/Gig and one serial port.

We have 15 small branches with Cisco 881w in every office, they use VPN site-to-site to vpn- concentrator on V yatta. I launched cacti monitoring of cisco 881's CPU's Errors, Traffics, Non-uni cast, Uni cast. I see that on 10.00 pm in one brunch when nobody works there, CPU load reaches 50% and traffic rises up to 9mbs.

recently we had some performance issues with C2811 which caused us to do some lab testing. For testing we used also C1812. The results were quite surprising for us, as the C1812 appeared to be more efficient than C2811. Below you can see the lab scenario and results.
1. Why C2811 is performing worse than C1812?
2. Is there any official Cisco reference stating what are the max VPN throughputs of certain platforms/models? (we consider migration to C2900 platform and would like to choose the right model)

as presented on the small diag:
All routers had enabled onboard hw VPN modules and SEC/K9 IOS ver. Configuration was very simple and beside encryption there were also GRE tunnels configured and EIGRP process for routing between "remote LANs". Part of conf responsible for encryption:

Any way to test throughput on a routed SG-300. I tried using iperf with netbook on VLAN1 to netbook on routed interface running @ 100mb. I was getting results as low as 40mb upto 200mb (sometimes even 2gb, I assumed these to be flukes). Since implementing it, the throughtput seems worse, I'm getting between 10 - 40mb of throughput. I have about 30 clients behind it routing across a 100mb leased link. I don't see why the SG300 shouldn't be able to do wire speed routing (upto 100 hosts). How to verify the expected throughput consistently?

I'm looking at replacing a CSS 11506 in a data centre with two Cisco ACE 4710 appliances. One thing that concerns me is the drop in throughput. The 11560 has a maximum throughput of 40Gbps while the ACE we are looking at is only 1Gbps. It seems that the 11506 is able to scale much better?Also, is it possible to run the two 4710s in an active/standby configuration?

Am looking at purchasing a router that is capable of serving a WAN bearer at up to 1Gbps. The 3945E has had good reviews as a high throughput router but the datasheets suggests performance of 350Mbps. It also states that additional performance can be ensured by adding SPE modules. Whether the 3945E could achieve up to 1Gbps with SPE modules?
If the 3945E can't achieve such performance, The key features I am after are:
IPV4 and IPV6 support
L2tpV3 support
BGP
IP SLA
1Gb Copper Connections on-board with capability of at least 4 Ports

We are bonding two LLU DSL lines using MLP. Our LLU provider supports MLP bonding and we have a few other customers working well on Cisco 1841s, although not such high sync speed lines as this problem site.
So the lines work well with no interface errors and sync speeds are very good and evenly matched between the two lines (approx 14Mbps downstream). It's all good - it's great in fact except that it just doesn't work properly! By that I mean we're not seeing the downstream throughput we'd expect. We actually get the downstream throughput of less than a single DSL line, so about 12Mbps. Upstream bonded throughput is fine and in line with the sync speeds.
Both circuits are 'active' in the PPP multilink bundle and I see 3 sessions on our core LNS Cisco 7301 (c7301-boot-mz.124-2.T.bin) - i.e. 2x circuits + 1x bundle. We've checked the circuits individually and 'actual' throughput (using NetPerf software) is similar for both lines and in line with the sync speeds.
We are seeing quite high CPU (50%) on the Cisco 1841 (c1841-ipbasek9-mz.124-24.T1.bin) at the customer premesis, but having tested a Cisco 2951 on the customer premesis with two new HWIC-1ADSL-M cards, this is not the cause. The 2951 ran at 5% CPU whilst we experienced the same problem.
We've checked the setup of both Cisco CPE and LNS with our LLU provider and they are happy with the MLP config. They themselves have been able to bond two similarly sync'd Annex-M DSL lines and get 25Mbps throughput on a 1841.

What is the difference between IP throughput routing throughput and firewall throughput
the reason is i am trying to spec a router for a mate who is setting up an online server for an old game ultima online which will have around 300-400 people each pulling around 10kb/sec
I recommended an 880 service router but when he spoke to a guy at the shop they said this would only run at 25mb/sec and he is plugging in to a 100MB/sec line
But the current router that is a home dlink which cost at most 60 Euros on a speed tester can pull 95mb/secI just don’t get how a 60 Euros router can download quicker than a 300-400 Euro router
They said try a ASA5505 that can do 150MB/sec of firewall throughput

I would like to know what is exactly the current throughput of device? How can we calculate if the device is reaching it's throughput?
For example if router 7200VXR has maximum throughput of 520 mbps as per Cisco documents.
How can we measure if the traffic going through the device has reached maximum throughput. Is it the traffic only inbound traffic or the total of invound/outbound on all physical interfaces?
