Cisco WAN :: 7206 / 2850 - Calculate Bandwidth Between 2 Routers
Feb 7, 2011
I need to know exactly how much bandwidth my service provider is giving me throught an MPLS network. My providers tells me that I am capped at 5 mbps with 4 T1 circuits but I believe that I am receiving 6 mbps.
I have a remote site in Dallas with a 2850 and another site as a head end in Michiagan which is a 7206 router.
What exactly can I do during non-business to test to see what the bandwidth is between the 2 locations? Is there some type of command that I can run on the router to test this?

I'm Connecting an endpoint to the switchport, the End client is a printer (Samsung ML-2850)Weird thing is after connect, the end point success got IP from DHCP server, but somehow cannot ping to it. For switching there's no concern, even I try with ohter PC connect to this switchport and it's PIGN'able. Only problem this printer cannot reach.
I able to see the MAC address entry of the printer at my ASA firewall, rule wise at this moment i just enable the rule as permit any any, no restriction at all.

I would like to find out what the status is of the Cisco 7204 VXR and 7206 VXR routers?I understand they are EOLife and EOSale.Are they also EOSupport? we planning to upgrade 3 of them in our environment and management requires feedback around this.We thinking of going the ASR1000 route..

We are migrating from a Microwave T1 WAN to a Fiber ring WAN which I'll be connecting to our providers Ciena Metro E switches. Eventually we are going to move away from the routers, but the network is a little too complex as well as spanned across a lot of miles. Since I am the only networking personnel here, I would like to first simply migrate to the fiber by simply moving the connection configs off of the T1 interfaces, and onto one of the Gig interfaces on the 7206 and on one of the Fe interfaces on the 3900 (which is actually a 3700 series because the line card on the 3900 is toast). If this works, I will need to purchase Fe line cards for the 7206, because I found out that the virtual interfaces do not support Policy Mapping for our QOS and Multicasting.

An IP packet of size 1500 bytes passes through two network segments before it reaches its destination. The header size of this packet is 20 bytes. The maximum size of an IP packet in the first intermediate network (its MTU) is 1024 bytes, and that in the second network is 576 bytes.Explain how the IP packet described above would be fragmented into smaller parts in a router, paying particular attention to the flag bits and to the fragment offset field in the header.
- Fragmentation and reassembly needs to break a data-gram into an almost random number of pieces that later can reassembled.
- It uses the identification field to ensure that fragments of different datagrams are not mixed.
- IP packet of 1500 bytes comprises 1480 bytes of data and a 20-byte header.
- In the first intermediate network, the packet size of 1024 bytes allows for 1000 bytes of data plus a 20-byte IP
header.[code]

I want to calculate Subnet Mask for 3 Router Each one in separate building the First building need 60 host and the second building 25 host and the last one 25 host .
Knowing that the company currently reserved public class C network address 210.2.1.0/24 for internal address and subnet 210.15.10.0/30 for the connection to the Internet router.

Given the IP address of 172.16.10.22 and the network mask of 255.255.255.240... answer the following:
What is the network address?
What is the broadcast address?
What is the valid host IP range?
What I have done so far:
Part 1 - Broadcast address
172.16.10.22 - 10101100.00010000.00001010.00010110
255.255.255.240 - 11111111.11111111.11111111.11110000
Researching different ways to find the Broadcast address I took the binary IP address and replaced all numbers with 1's for the host bits identified in the subnet mask and came up with:
172.16.10.31 - 10101100.00010000.00001010.00011111
Is that the correct Broadcast address?
Part 2 - Network address
I am not sure what is meant by the network address and all my research has come up with either MAC addresses (obviously wrong) or CIDR notation...How do I calculate the network address?
Part 3 - List of valid IP's
Using the same address 172.16.10.22/28 I did the following:
28 is closest to 32 (block wise) so 32 - 28 = 4... 2 ^ 4 = 16 (block size)
IP address listing:
172.16.0.0
172.16.16.0
172.16.32.0
172.16.48.0
172.16.64.0
and so on...
The IP address in question is 172.16.10.22 and falls in the 172.16.0.0 - 172.16.15.0 block...
Is this the correct list of valid IPs?

I want to measure the the ospf convergence time on the given network topology (assume 5 nodes - partial mesh topology).I am using quagga software as routing software on linux box. Quagga is runnign fine and network is converged, able to see all the routes.. Quagga software is logging all the osfp information includign packets,state machines,etc.I am going to disconnect a link between node a to node b. and i want to measure the convergence time of the network.What is the network convergence time?My answer is, The time taken to reflect the topology change (link down/up, network condition change) to all the routers on the topology.Some routers(close by routers to the topology change) will get converged fast, and some routers(far away from the topology change) will have the higher convergence time. we have to take the highest convergence time of the router on the topology and we can says thats the ospf network convergence time.

When someone downloads a file, or similar, there seems to be no, or very little, room for other requests. I've even tried to be the only one on the network, start a download (from ex. Intel) and then tries to access a simple website, almost only text, and its extreemly slow. I hav ethe latest firmware, a windows domain network and the routers is not acting as dhcp server.

I just got the RV042G today. I found the router can only accept 100000 Kbit/sec as bandwith, which is 100Mps only. According to the specification, it should have 1000Mps WAN. I have a internet link of 1000Mps, which is now limited by this router.

Since I've bought my RV042 CISCO (v3 hardware, firmware v4.1.1.01-sp Dec 6 2011 20:03:18) i wasn't able to let it work properly with my two DSL network lines. I explain. I got 2 DSL network:
1- PPPoE with authentication (MTU setted as auto) with upstream speed 4Mbit/S and downstream speed 5Mbit/s
2- Direct line with static IP with upstream speed 7Mbit/S and downstream speed 1Mbit/s
I was never able to SUM the two WAN using the LOAD BALANCE set. I tried all combinations:
DSL 1 in WAN 1 or in WAN 2
DSL 2 in WAN 2 or in WAN 1
I've tested all type of speeds in WAN SPEED in Web Management
it seems that for some kind of reason it takes the upstream speed i can set in web management as the default value on which it decides to use the other WAN. When i set low upstream bandwidth for DSL 2 it's able to sum the down streams of both WANs but not the up streams.
I wasn't ever able to sum the up streams? How does it work?

I have an RV220W which I would like to set bandwidth limiting on. When we upload files to yousendit or an FTP server, it saturates the connection and essentially stops any other traffic until the upload is finished. Looking at the manual, it looks like it should do this, but does not seem clear to me.

setting up Rate Control in Bandwidth Management. It doesn't seem to work at all. I knew from some other Posts that I need to have IPS on and I do.. Is there something else I need to do.
My users are connected wirelessly to the router through three different SSIDs and I have 3 VLANS. I need to set some limitations on two of the LANS.

My home network has two routers. My setup is...modem to router 1, then router 1 to router 2. is there a way to track the bandwidth usage on the two routers. My ISP says that I'm going over my bandwidth allowance and that's because in my household, we are hardcore gamers, netflix, and internet users. Router 2 belongs to my sister-in-law, and router 1 is mine. But I want to know which and more importantly, "WHO" is using more of the bandwidth.

I have a RVS4000 hardware v2 with firmware 2.0.2.7. I have a DSL modem in bridge mode and have the router set to PPPoE. Everything works fine except I want to use QOS which doesn't work fine. I have some vonage boxes set up on a switch set to port 1 trust mode is set to port and level 4 for highest priority. Port 2 I have on another switch set to priority 3. I tried turning bandwidth mangement on which doesn't seem to work at all so I don't even know if they QOS is even working. I set the max down stream and upstream provided after running a number of speed tests and setting it a little lower than my worst speed results. Once I did that I set up a rule for all traffic for rate control and set them just below the min and max I put in for isp bandwidth. I set the ip range from 192.168.1.100-190 this will cover anything that dhcp hands out and I also have a few statics set up on 192.168.1.180 and 181. However after enabling it I ran some speed tests and I still get full speed and the rules seem to be getting ignored.

I currently have the following network structure, which work fine:
The only bandwidth management configuration I did in the Cisco E1000 router is to set the QOS, giving high priority to the 5 SIP Phones mac addresses.
The problem: I purchased a Small Business Cisco router RV016 because the company keep expanding so they will add more SIP Phones and PCs. In the new router configurations, there is no way to do like I did on the E1000 I just want to be able to set high priority to the SIP Phones mac addresses.
What happens when I use the new router (RV016) is that, sometime you dial a number and the phone do a busy signal and indicate "Call failed" or sometime people call in and there is only 3 phones ringing.
I tried port forwarding.. disabling firewall.. SPI.. I tried access rule.. whatever I do doesn't fix the issue.
When I put the Cisco E1000 back everything goes well.
I'm using the latest firmware: RV0XX-v4.1.1.01-sp.bin

After configuring the router and enabling a load of functions to secure our LAN, the download speed halved! Even disabling AcitveX "eats" 10Mbs! I understand that enabling IPsec will drag the speed down to 25Mbps, but I have disabled this.
Even setting the QoS to speeds equal or higher then the ISP's promissises drags the speed down!

I Just got FIOS internet at Home with 43 Mbps down and 32 up (measured speed). I replaced the included router with my old reliable RV042 (V1) VPN router that I used with my old service in NY LI. This has been working very stable for week or two, but I use my old 042 to remote desktop via VPN from my work, that was limited to maybe 9-10 Mbps (Home to office) way down from the 32 up I have now (the office has 80Mbps down). So I researched that the RV220W had a VPN speed that was much faster and I ordered one that I am trying this weekend.Out of the box, I plugged accessed and just clone the MAC at the WAN port to match the replaced FIOS router. Power cycle and surprise, no IP from FIOS!. After trying a number of things, I gave up and updated the firmware to the last 1.0.2.4, and that fixed this. I still need to clone the MAC to void calling Verizon FIOS, but at least I get IPs and Internet with no trouble.Next, I configured a couple forwards for two web servers. I found about the bug in this same forum and just used the rules instead. Working good so far.
So now I test WAN bandwidths, and I found all kind of trouble. With the old RV042 and similarly to the included Verizon router I can do steadily 43d/32u. Especially at night is quite stable in these numbers. When I went and move the cables to the RV220W (exact same set up) the speed went all over the map from 4d/8u to 43d/25u. If I power cycle the box, things tend to be stable again around 43d/25u. So, after a while being stable in these numbers I start trying things to improve the 25u that should be around 32u, and recover the missing 7 mbps. Not much I can think, so I just randomly enabled the QoS settings trying to reserve full BW for my tests, and I found just that enabling WAN QoS, and nothing else, no profiles or changes in the Priority Settings, I go up to 30u consistently over a number of tests. This do not affect the down speed that is stable at 43 mbps. The surprising thing, is why this affect to the up speed when nothing else is going on in my network? and also where are the other 2 Mbps to complete the 32 Mbps that I can do with the RV042 (V1) or the cheap included router? In my opinion, if I don't use QoS, I should get full bandwidth to whatever application/computer that requests so, period.

Buy a router RV120W, and one of the reasons is limit of bandwidth (QoS). I set up a profile of 1-256 kbps limit, and apply it to the only VLAN that is configured, but does not work and can navigate using the full bandwidth of the internet connection. My firmware version is 1.0.2.6

What the differences are between bandwidth management on WAN ports and protocol bindings?
If you can specify in each section which protocol should go where why having two places to configure this?Or are there some things to remind when using one of them?

I bought a RV042G router some days ago to manage 2 adsl lines at my home. Everything works correctly except one thing : i can't configure the bandwidth management. When i go to "Bandwidth Management" menu, then "Bandwidth Management Type" then i choose rate control or priority and i a had some rules to priorize http protocol for example, then i click on save button. After a few seconds of internet usage i loss connectivity to the router and internet and 192.168.1.1 became unreachable to ping. I had to unplung the power cord to restart the router, the same problem still occurs until i remove all the rules ! Some times i even had to do a factory reset because my adsl modems are unreachable behind the router (unable to ping the gateway).

I am trying to set up my router to grant http traffic a minimum bandwidth of - for example - 5,000 kBit (if there is any http traffic).
So I set http min. rate to 5,000 while I set nntp min. rate to 1 However, when I run nntp downloads on several connections (e.g. 10) my single http download never goes above 1,000 kBit. Without any other connections I reach 8,000 kBit.
I am using a single 12 MBit line.
