Cisco WAN :: Add T1 To MLPPP Decreases Bandwidth?
Feb 27, 2013
I have 4 T1s going to a site, 2 of which are new (all 4 are with the same provider).I initially noticed that throughput of the 4xT1 bundle seemed a bit off, so I did additional testing.I found that whenever I have a certain T1 in the bundle (whether its 2xT1, 3xT1 or 4xT1), throughput is drastically decreased.There are no errors on the circuit, so my provider is being difficult about "repairing" it since they also see no errors.

I seem to be having an issue getting a 3xT1 bonded solution to work. I can get 2 out of the 3 T1s to come up and pass traffic, but I can not get the third one to be added to the solution.

I am looking into installing new service with a new ISP and it looks as though we may have to go copper which would give me an NxT1 type link to get the bandwidth we need. I have another location that is currently doing NxT1 IMA on the 3825 platform but that platform and the interface cards have had an EOL anouncement. The EOL anouncement recommends the 3900 platform as the replacement but I am not sure what I need in the way of interface cards for the NxT1 MLPPP connection. Can the NxT1 MLPPP connection be supported on the new 2900 series platform or do I need to move up to the 3900 series?

My download speed has decreased to about 1/40th of its previous speed, while my upload speed remains the same. Speedtest shows that my connection is equally strong as it was prior to the slowdown, even though I can't even get anything close to my original speed.Fully detailed version: About a week ago, my download speed decreased from 2 megabytes/s to about 50 kb/s. Prior to the speed decrease, I did not install or update any programs, so it's probably not an interference from some wayward program.

We are using WI-FI with more than 20 clients at a time.Now the speed seems to very decreased,because most of them using torrents for downloading.Is this the correct reason for low speed?How can I detect who or howmany people using torrent?And is there any need to block torrents?

My internet connection speed, measured by speedtest.net with PC connected directly to cable modem, is ping=33ms, dn=48Mbps and up=7.6Mbps. (These values changes slightly with each test, sometimes being a bit higher and sometimes a bit slower, but usually being in the neighborhood of the 50Mbps promised by my ISP.) When this same test is run with the PC connected directly to a port on my RV180 (firmware version 1.0.1.9) the measured speed is ping=35ms, dn=30.66Mbps and up=7.45Mbps. Given that the RV180 is supposed to provide very fast WAN to LAN throughput (Small Net Builder's test result is 798Mbps dn and 811 up, measured with the same firmware version), why is my unit seemingly decreasing the internet connection (WAN) speed coming out of my cable modem? What, if anything, can I do to increase my WAN to LAN throughput?

I try to connect Siemens SIP IP phone to switch LinksysSRW2008P with PoE for scheme:
main switch <-------> linksys <-------> phone
I can't have access to Linksys by local network or web interface, so I connect through COM port and reboot the device and restore all settings to defaults. There was another linksys switch with the same default IP in my network, so I've tried to change ip address for my Linksys device. After that I can ping switch IP without lost packages successfully and partly access to login page by web, but including Linksys to the local network causes decreasing all network working speed, so the web administrative form can not be loading at all. In both cases (default ip or another one) the set isn't working, so I can't have access to the phone by ping or web interface. The cable to main switch inserts to port 1 and green rectangle indicator is flashing rapidly. The cable to the phone inserts to port 2 and orange indicator is lighting, green indicator is flashing slowly. Interestingly, only one port has status UP (port 1), all another port has status DOWN. If I replace cables ports with each other, only the port where cable to main switch is inserted, will have status UP. The phone station is getting power from switch in both cases. I've tried to change Spd/Dpx ports' parameters, used DHCP for getting IP, but I've gotten no result. How can I solve the problem? Is Linksys switch worked or defective?

I have TL-WR740N router. ISP should provide me up to 100Mb/s internet speed. Actual measurements shows me about 80 Mb/s. The problem is when I enable 3389 port in Port Triggering my internet speed drops to 2,5 Mb/s. When I disable port triggering, speed become normal again.

We have 1 mpbs bandwidth line, but most of the time we are getting only 300-500 kpbs download speed, i want to send statistics report to our ISP, what will be best procedure to test the bandwidth report, i have checked in some websites like bandwidthplace and speedtest but these sites are not accurate, how to check the actual bandwidth we getting from ISP against 1 Mbps. We have solarwinds monitoring tool in this i have configured the WAN interface for 1 mbps

I'm trying to use a 5520 to test something but the bandwidth seems pretty low for the product I'm testing over it. Can anyone tell me if there is a bandwidth limitation by default? I'm seeing 1.5mb/s average with spikes to 6mb/s or so. On the ASA5550 I was seeing usage up to 80mb/s.

I have got a very basic/fundamental doubt.I would like to know how a bandwidth gets distributed in switches.for example consider a scenario where i have a coreswitch A and coreswitch B connected between each other througha a 1Giga Fiber now each of my core switche are connected to two edge switches through fiber links. all edge switches have giga ports. now if i connect a pc with giga link in th edge switch of coreswitch A and tansfer a file to a PC connnected to the edge switch in network B.how does the switch allocate/distribute bandwidth?

I am using ASA 5505 cisco firewall as a transparent firewall. I have assigned ethernet 0/0 as outside interface and ethernet0/1-7 as inside interface. There are 3 departments in office. So, i connected ethernet 0/1 to Dept A, ethernet 0/2 to Dept B and ethernet 0/3 to Dept C. Now, I want to limit bandwidth to each department, e.g, 1 Mbps download/upload to Dept A, 512 kbps download/upload to Dept B and 512 kbps download/upload to Dept C. So, how can i do this in ASA 5505.?

I'm pretty new to this, and I've been trying to read up on what I should do. Here's my situation: we have a new 15mps internet connection coming into our building. We also have a new 891 router. We would like to devote 1.5mbs at the highest priority to one LAN which is just used for VOIP phones. We would like to allow one of the other tenants to use up (but no more than) to 5mps for their LAN, and we'd like to be able to use up to 13.5mps for ourselves if it's available, or at least 8.5mps (15-1.5-5=8.5).
From searching in here and reading the various articles on policing and shaping, I'm thinking that we'd want to set up Class-based weighted fair queuing on a per-interface basis, and have one interface connected to our VOIP switch, one connected to the other tenants switch, and one connected to our firewall. Does this sound like the right way to go? And would anyone have an example of a configuration which achieves this?

I have a WLC 4404 installed and we would like to manage the bandwidth per SSID.
Today we have configured many SSID because our campus has a lot of wireless users and any SSID has only one class C subnet (/24).
We would like to configure each SSID with more subnets. is this possible ?
Additionally we need to restrict the bandwidth per SSID. is this possible ? We have some SSID for less important users and we would like to assign the bandwidth per SSID.

I am having trouble with a T1 connection between a cisco 7200VXR and cisco 2600. I have no problem connecting across it, but when I run a download across the link I get a flat 6KB/s. I can't seem to find what is wrong in my configuration that would be causing this.

I have a bundle of 2 T1 into a multilink interface. However, I have encounter an issue, last week, our ISP lost one of the T1 and it went down hard for at leats two hours. Once the T1 came up, the bandwidth still was 1544, but once I shutdown and no shutdown command in one of the serial interface the bandwidth came up as 3074. Here is my basic config for the 2911 router. [code]
I just don't know why the router was not using the whole bandwidth of 3044.

I just wonder if there is simply way on Cisco 800 to set bandwidth priority for internal IP address. Basically I have server and would like to make sure, whatever comes to it or goes out has the highest priority and users won’t kill bandwidth for the server connection.

I have a 3845 Router with three connected interfaces, one to my WAN, one to my LAN and another to my wifi zone. I want to limit the amount of WAN bandwidth the WIFI zone can take to say a max of one third and not restrict WAN bandwidth from the LAN at all.

I have cisco 7600 core router in ISP , i want to put the bandwidth limit on it for outgoing traffic (for internet) on a subnet because i am using Bluecoat and i want to test my bluecoat.On this subnet i have no limit for bluecoat but after the bluecoat i want to limit it. On 7600 cisco router i have not rate limit command so how it can be possible for a perticular subnet ?

I have a RV042 with a DSL (static IP) and a cable connection (Dynamic). How do I get the extra bandwidth from the cable and still keep the static IP of the DSL. When I have the router set on WAN1 (DSL), I get buffering. When I set the router on WAN2, I lose the static IP and therefore, the stream. When I have the router set on Load Balance, it switches the IP back and forth between the static DSL and the Dynamic cable.

I feel a bit in over my head here as I've never dealt with QoS stuff before, but what I'm trying to do can't be all that difficult. We are using a Cisco ASA 5505 appliance for routing/firewall.We are on a cable Internet connection with 3 MB upload.
On Sunday mornings, we send audio from a device on our network out over the Internet to a radio station which then broadcasts it, but we've had some jitter problems lately and would like to reserve some space for this audio feed to get out without other traffic getting in the way.
The device on our network sending the audio has IP address 192.168.0.22. The device's documentation states it uses TCP 9002 to send session data and UDP 9000 to send the audio data.
So, it seems to me I need to simply tell the firewall to give priority to the device at IP address 192.168.0.22, perhaps also specifying the ports and protocols. I'd rather not try to do this using command line stuff but will do what I need to.
Using the Cisco ASDM launcher to configure the ASA 5505, I created the following security policy but I'm thinking it may be incomplete, or perhaps the wrong thing altogether:
I created a "Source" called WLFJ_Tieline which is a network object with IP address 192.168.0.22.For "Destination" I just chose "any" to cover it all.For "Service" I don't know what I'm doing in that field. I see I can choose from things like TCP, UDP, IP, and also add port numbers, but I'm just not sure what I'm doing in there and chose IP.Then there is the "Source Service" field that I don't know if should be blank.

We have a Cisco 1941 Router with two single HWIC cards supporting two T1 lines 3Mbps total bandwidth. We have a distance learning lab that takes atleast 2mb connection when in use so it realy kills our bandwidth. I was looking to possible add a thrid T1.
My question: Can I just buy a double wide HWIC card and replace the single port one. Would this require re-configuration or it's simply plug n play?
What other options can I try for more bandwidth instead of adding thrid T1.

I am looking for some tips on managing my router. I have noticed lately our bandwidth useage has gone up and maxing our DSL line.Cacti is monitoring just for traffic trending and I am in the middle of getting NetFlow going.
Our router sits on the edge with no internal way to access it (or at least so I think right now.)
My thought is to enable NetFlow and port forward it into our network and use ManageEngine to see whats going on.I dont have any ACLs running on the router... We have two connections DSL and T1, I have them into a routing policy.Our nating and firewall sit behind the 2811.

We have point to point metro ether net link terminating on 7204VXR router.On this point to point link we are configuring GRE over ip sec. Problem is when the traffic exceeding 8mbps we started getting packet drops. from the Cisco documentation it seems the tunnel bandwidth is by default 8mbps and there is parameter like Inherit/receive but those actually not change the tunnel interface bandwidth.If we just give tunnel bandwidth with bandwidth mentioned it allows me to give option of 100mbps but again the tunnel interface bandwidth remains 8mbpos only and probably that 100mbps is useful only for routing decisions.
i am using advance security 12.4.15T12 image. Whether this is a limitation or any other way to go beyond 8mbps for the tunnel interface (7204VXR-NPEG1 processor)
