Cisco WAN :: 6509 / 4506 - Measuring Actual Bandwidth / DS3 Lines?
Jan 9, 2012
I'm currently in the process of doing a bandwidth analysis on 2 WAN links at my current HQ / remote sites. The topology is pretty straightforward, two 3845 routers at HQ, and two 3845 routers at my remote site, both with P2P DS3 interfaces between them. From each router we then connect directly into a 6509 at the HQ, and a 4506 at my remote site where we are using equal cost load sharing (EIGRP) to split the load / give us redundancy between the sites.
I'm just looking for a good test for how well the circuits are performing. I've done some basic file transfer tests, but they're only showing about 4MBPS, which seems quite slow. I also know that this isn't a true measurement because there are amny different factors involved, like hard drive write speeds, network congestion, etc, that may influence the test.
I have a small call center and we are struggling with adequate dsl bandwidth for our voip. The providers cannot give us more upload bandwidth. Any way to combine the bandwidth of two or more lines so that the server/switch sees increased bandwidth for upload?
I'm going to combine 2 512 kbps ADSL line in my PC. i know that it would be much better to get a 1 MB ADSL connection...but the problem is where i live now there is not better speed than this! Well i have a PC with 2 LANs - 2 phone lines - 2 ADSL modems - as far as i learned from Google , by no means it is possible to combine them to have 1 MB data rate but it is possible for example IDM would works with one 512 and another program with another 512..!! And load balancing is the only solution for this which it needs a special routers ! it is somehow difficult for me to provide one ..!! so my question is :
1- Is there any other solution for combining this 2 lines?! I heard something about teaming. 2- Is it possible to use load balancing by software? 3- How about the efficiency and ping time?
I just started a new Position and they have CATos still runing on some of there 4506 and 6509 switches. I amy trying to come up with a plan to upgrade the switches to IOS but I dont know if they will take it or not. I know I need to get flash Cards to hold the IOS but i need to make sure that I get the right IOS for the Switches.
a 6509 and a 4506 with 2, 1gb interfaces in a portchannel. Bring it up and everything is fine. Save the config and reload either switch and the interfaces stay in Not Connected state. Either doing a No Shut or a physical unplug the SFP and plug it back in will bring it up with no issues. Interfaces do not go into Err Disabled state they stay in Not Connected like there is no fiber plugged into it. No error mesages in the log. The Just the Interface is now up.Both are running very new code,
6509 - s2t54-ipservicesk9-mz.SPA.150-1.SY1.bin ( 15.0.(1)SY1 ) 4506 - Version 03.02.00.XO
If two (one 6509A 9/26 with server A located in A end, 6509B with serverB located in B End) which is connected via a 1G link. If there is serverA send 700M file to server B via a 1G link. If I configured below command to 6509A 9/26, can I limit the bandwidth of server on bothincoming and outgoing to 500M?

We are a new medical school located in PA. Just have just completed a new building and are now working on getting our network finished. Here is the situation we have a 50MB Internet Connection that comes into our network that then hits the ISPs Cisco 3750 which sends it to two of our Cisco 3750s for redundancy. From the 3750 goes into our Cisco 6509 with a FWSM module, then out from there to our distribution switches which are all Cisco 2960s.
What we would like to do is to control how much WAN connectivity each of our VRFs get. Right now we have a Faculty, Student, and Research VRF formed, and are trying to figure out the best spot where we can say Faculty gets 30MB of Bandwidth, Students gets 10, and Research gets 10. If possible would like burst capabilities.
I was looking at a problem where a traffic from certain sites have a restricted bandwidth, an ongoing problem for a year or so, apparently this throughput never exceeds around 25Mbps. My customer describes a situation where the end to end utilisation rises, eventually flat-lining at around 25Mbps. how many extra systems come on line, this traffic never exceeds this rate, and end users complain of poor responses.
During my investigation I found that one of the switches (Cat 6509) in the traffic path has a policer configured on a vlan interface, the policer has 3 sections for different traffic based on DSCP markers, and a default (unconfigured) class-default. Various people have had a poke about with this config over the years, with the result that all the traffic has the CoS and DSCP tags set to 0. All this traffic is hitting the class-default in the policer.The link that this traffic hits the Cat 6509 on is a 100Mbps link.
If I was designing this from scratch I'd probably configure a rate for the class-default.my question is, in the case where no specific configuration has been entered for the class-default, how much bandwidth is allocated to this class?
My company is composed of three different campuses, all with a similar network topology. We currently are experiencing high bandwidth on our serial interface at one of the campuses in particular. The network is composed of about 20 VLANS routed internally using a Cisco 6509. Traffic to the outside is PAT’d by an ASA 5510 and then forwarded through our edge router interface. Each VLAN is PAT’d to a specific public address.Due to the PAT, how would you recommend determining what specific private addresses are consuming our resources on the serial interface. When I look at our NMS, it reports the public address, but that only narrows it down to a VLAN. For example, all the devices in VLAN 6 are translated to 146.34.118.245, and 146.34.11.245 is a top talker.
We run a workers camp here and we currently have around 2500-3000 people using our 100MB internet pipe. We are upgrading the pipe to 200MB soon but I still would like to limit how much bandwidth everyone is using.
We allow streaming media such as Netflix, youtube, apple TV and of course .So it gets full pretty fast. We have QOS implemented although I wasn't here when it was done so I don't know a lot about it. I would like to limit IPs to a certain amount of bandwidth. [code]
Any actual limit on the number of IPSEC SAs that can be negotiated on the crypto module of a 3900 series G2 router? When I issue the command on a 2900 G2,This implies the 2900 series can handle 1800 IPSEC tunnels with an SA used for each direction. All of the documentation and support requests have stated that the crypto module is better than the AIM module in the older series routers but I have been unable to get a concrete answer to the limit.
1. what are the actual functions/roles of a router firmware? Does the firmware work at routing or forwarding? 2. does the firmware automatically processes data? or...can he do that? 3. if a person connects to the internet through the router...does he came in contact with the firmware functions? 4. is the firmware accessed only when the user enters the configuration panel of the router?
I'm having what's probably one of the strangest computer problems I've ever dealt with. The computer I have set up as my media server (Running Windows 7 Home Premium 64 bit) is randomly losing network/internet communication. Now, I say communication and not connectivity, because I can still ping it from other computers on my network and I can still ping websites from it (via IP address or name so it doesn't appear to be a DNS problem). But I can't pull up any actual webpages when this problem is going on and none of my media services will connect to the PC. I can't even pull up my routers admin page from the PC while this problem is going on (but I CAN ping the router).
Lets say i have 2 3750 switches stacked via backend stack cables. Now if a packet needs to go from 1 switch in the stack to second switch in the stack, will it travel via stack cable or do we need to connect both switches via uplink ports (ethernet or sfp). I tried reading datasheet but it no wheres mention the actual frame path between switches in stack.
how can i discover product actual part number from the device through console.I have a bought a cisco ASA5540-AIP20-K9 and i want to check either is the product is shipped us as a right product.And i want to check total BoM requriements from entering the ASA console through any CLI Command.Below My Cisco ASA BoM which i purchased.

I have a 5520 in production at a customer's site between an outside 802.11 network and an inside server. The server can get to outside hosts OK, and the traffic is being NATed properly, and sockets initiated by the server on the inside can pass data both ways, but I need to allow outside hosts the ability to send 'announcement' UDP packets to the inside server. I thought this might be an outside-NAT-required issue to get the traffic routed, but I need the inside server to see the actual outside host source IP in the UDP packet, so I basically set the outside host up similar to the inside host, just without the NAT table on the firewall -- it's subnet is outside the destination (inside server) subnet, and its gateway is the outside interface of the ASA, the same way the inside server is able to get to hosts outside. The firewall should just route the packet with a destination of the inside subnet once it sees that it hits a 'permit' ACL.
I have the appropriate ACL's set up, and when I do 'show access-list' I see policy hits for the 'permit' statements where the outside host is generating the announcement and it's hitting the ACL. I even duplicated the ACL into list 101 and 102, and applied 101 for inbound traffic on the outside int, and applied 102 for outbound traffic on the inside int, and I'm seeing policy hits on both permit statements outside and inside, so it looks like the traffic is being passed on to the inside interface and permitted, but the server isn't seeing the packets.
I can ping the outside interface from the outside, but cannot ping the inside interface or any inside hosts from the outside, even though I have 'permit icmp any any' enabled on the ACL on both ints. When I remove the firewall and put the outside clients on the same subnet, the server sees the packets just fine.
I set up the same scenario in my lab with an ASA 5505, with the same results. Below is the running config from the 5505 in the lab. The production firewall is running a slightly older version of ASA, so I made the configuration as basic as possible on the 5505 to match the config in the field:
Region : Argentina Model : TL-WR740N Hardware Version : V4 Firmware Version : ISP :
Region : UnitedStates Model : TL-WR702N Hardware Version : V1 Firmware Version : ISP :
I know that the 150Mps is peak speed. I wonder how to test the actual through speed of the router. Like what average speed do I get for 10 minutes of continuos streaming Speedtest.net is not useful because is just giving me the ISP speed instead of the router speed
Soon my town will be getting fiber to the home, so I've already upgraded my home network to handle this. One of the changes is that I'll no longer use my powerline adapters to stream video, but to transfer the IPTV data. For streaming I wanted to switch to Wifi, so I bought the E4200 and compatible adapters and bridges (see subject).The powerline adapters have a bandwidth of 200Mbps, of which I get an actual 120. This works fine except for full 1080p, that stutters. The E4200 has a maximum of 450Mbps, but the adapters and bridge only do 300, but that should be sufficient. So after replugging my network, I tested it last night by playing a 350MB 45 minute episode of a TV series... And it stuttered!
Doing the math, that would mean the connection was less that 1Mbps! The WUSB600N and E3200 were (direct line) about 4 meters apart, separated by a concrete floor. What is the best way to measure the actual connection speed?And more important; since the E3200 does both 2.4GHz and 5GHz, how can I tell which band the adapter is using? I want to use the 5Ghz band, since that is fairly empty compared to the 2.4Ghz. However, I've configured both with the same ID, as the E4200 manual instructs, but I think it may be better to separate them?
I have 2 cisco Aironet 1252 setup as a point to point link using an external antenna (one radio is setup as the root bridge the other is setup as the non-root bridge). Now I see that the connection between the radios is established at a speed of 54 Mbps. However when I perform a speedtest on the link I see that the my actual download speed does not exceed the 2,5 Mbps. what can cause my actual speed to be far lower than the 54 Mbps? And what can I do to improve it?
Today I was playing the ps3 (call of duty MW3)... normally I would connect via wireless but I'm getting a ton of lag and it's becoming frustrating. Later on I moved the ps3 downstairs and connected it via Ethernet and it worked so good.I want to look into buying those Ethernet power lines but not sure how good they are compared to running a Ethernet cable from the ps3 to the router or how good they will be vs wireless? I just don't want to waste money on these. If all else fails we will probs run a Ethernet cable through the ceiling
I have setup a site to site VPN with an ASA 5510 (8.4) and a Cisco 2811. The tunnel is working fine, however both sites have 5 different contiguous networks. The crypto ACL between sites states only one subnet.Is it possible to state a summary address in an ACL rather than having five lines for the ACL?The tunnel works when the router uses an ACL of 10.2.200.0 0.0.7.255, however if a summary address of all the subnets on the inside network of the ASA are stated in an ACL - 10.1.200.0 255.255.248.0 - then the tunnel does not come up.Is it possible to state a summary address on a crypto ACL on the ASA?
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.
I work for an ISP and we are currently bonding 5x 6Mb ADSL connections for use as a wireless backhaul. We are currently using a Cisco 3725 and bonding the links via MLPPP. This set up is working fine except that we are not getting the full 30Mb on the download side. We are seeing more like 18 to 20. I am wondering if we can acheive the full speed with our current set up or will we need something different to get the job done.
My remote office staff are stating it takes "forever" to open simple work/excel files.I think forever really means more than 5 seconds.My main office has a 5510. I have a brand new server in place here that my remote offices vpn into. Those remote offices have 5505.
Each office has a dsl connection. Their download speeds range from 7mb to 10 mb and their upload speed are 0.5 mb to 0.8 mb.My first thought was to add a second dsl line to my main office. Then have dsl line #1 serve my main office and office 2.Then have dsl line #2 serve offices 3, 4 and 5.
Would this speed up the opening speeds of my remote offices?If so how challenging is adding the second dsl line into my 5510?
I was recently tasked at work to reinstall phone lines after a remodel. We have 2 phone lines with two phones and a credit card machine. I ran into a piece of equipment and I have no idea what it is so my research into the subject has been halted.
I have 4 ADSL lines from the same ISP going into one Cisco 887VA router. How can I do load sharing between the 4 lines without getting the ISP involved?
I've 6 ADSL lines that provided by the same ISP and i've Cisco router 2600, so, how can I connect the six lines to the cisco router and running load balancing between them ??
I have an ARRIS modem supplied by Comcast cable. I have an hp pavilion x1958 and want to run internet service to a secondary computer from the same modem. And I don't have money to buy a router. How can I do this the cheapest way?
Im planning to do a LAN for internet/file sharing and of course LAN game There are people that living far from each another like 1 mile away.... thats a problem.Cat5 Ethernet cables are not made for long distance connectivity ( 100 meters of length max, otherwise bad connection).So because i need a connectivity between pc's for long distance I can use Wireless, expensive, and because I prefer wired and I heard that there is a way to convert CAT5 cable into phone line, because phone lines can be used for long distance connectivity without problems.So I wonder if there is a way to do that LAN connectivity using phone lines.RJ45 to phone line, do they exist these adapters? if yes, will this work for me
My linksys router all of a sudden stopped recognizing the 3 LAN lines that are hooked up to it, we are only able to access the internet via wireless. any suggestions on why the router would all of a sudden stop recognizing the LAN lines?
Our work building currently has 2 separate DSL lines feeding into it, one on each end of the building. The reason for two lines was so each one would have its own bandwidth, thereby supporting more simultaneous users. There is a router connected to the DSL jack at each end of the building, broadcasting its own wireless network: let's call them Work 1 and Work 2.Is there any way for me to connect the Work 1 and Work 2 wireless networks, so that they appear to the end user as one contiguous network?
