Bandwidth Consumption through RV180

Hi,
I am working with a customer utilizing a RV180 as their EDGE device and an SF102 small business 24 port switch for switching. At times, we are experiencing issues whereby some device or devices are consuming all available WAN bandwidth, causing the internet to be poor-performing at best during this timeframe. We are looking for a way to determine what specific host or hosts are consuming all of this bandwidth. I know with an ASA you can set up Netflow through PRTG - can this be done on the RV180 and if so, how can I set this up? Or is there some other methodology I can use to find the culprit host(s)?
Thanks,
Mike

ok - I'm official outside my comfort zone. I took a tcp dump and analyzed in wireshark (the sniffer previously known as ethereal). I am seeing a lot of ARP packets that originzate from my ISP's routers.
Couple of questions for those who know more.
1. What is a lot of ARP traffic? I am seeing 220K packets & 15MB over a 10 minute span. I would think this is a bit excessive. Is it realated to the size of their network. At my last provider, I saw total inbound traffic during quite periods (late at night) of around 10MB per _hour_, so that is my limited comparision point.
2. Can I safely block this traffic in iptables? Some of it if it is not directed at my MAC address? Or should I just not worry about it and filter it out of my network reports when looking for problems.
Thanks,

Bandwidth detection causes bandwidth consumption to spike

Hi everyone,
We are having a little problem implementing bandwidth detection with FMS, for some reason when enable it, bandwidth consumption spikes significantly I am wondering why? and if there a white paper somewhere that would talk about how properly implement this feature.
Kind regards.
+LA

Hi,
I dont think this should happen anyways can you tell exactly how did you concluded this. I mean to say how are you finding bandwidth usage as well as bandwidth detection.
The following link might be helpful for you.

Bandwidth Consumption - How to Identify

I am having an issue reconciling what I am seeing on my box and what my ISP is reporting that I am using for bandwidth consumption.
For a sample hour, they report the following usage:
Usage: 0.240 GiB In / 0.374 GiB Out
Which if I am reading this correctly is 240MB in and 374 MB out.
However, when I use a utlility called vnstat I am getting:
112 MB In / 247 MB Out
Question: what other tools should I be trying to use to identify the discrepency. I thought I could be hacked, but I'm pretty sure I have not been compromised (not 100% though). I run very few services (ssh / http / smtp / pop3 / imap), run osiris on it nightly and various rootkit detection scripts.
The CPU utilization is about what I expect; I just don't understand the wide differences in the bandwidth consumption.
I realize this is a pretty broad question, even a pointer where I can learn more about how to analyze network issues would be appreciated.
Thanks,
Chris....

Network top talker! Bandwidth consumption!

Hello,
what is the best solution in cisco world for finding the top talkers in the network.
I need to know what bandwidth consumption per IP.
I found out that Cisco IOS router with solarwind using SNMP.
Does cisco ASA generate this kind of reports?

RMI bandwidth consumption

we're about to deploy a new third party RMI-based application.
The application is supposed to receive client connection through WAN .
running an initial bandwidth test to try to detect optimal bandwidth, we assumed worst-case-scenario where a 128kbps
leased line was used for client connections.
With only one client connecting, the bandwidth was fully used for 70% of the time and the client's download rate overcame its upload's.
since we have the sources and license to edit of the application, i looked up tis code a bit and i noticed that most of classes the client had loaded and was initiating the calls from existed only at the client side.
if those classes,existed in the server's classpath as well would that diminish the client's upload rate assuming that then the server would have whatever objects definitions the client is referencing through its calls ?
I might then alter the code in a way to redeploy the classes efficiently.
i don't know if i was clear enough, i could use some advice though.
thanks

ejp wrote:
The server only needs the classes that are reachable from the remote interface(s), and it most probably already has them. RMI doesn't send classes over the wire unless the java.rmi.server.codebase feature is enabled, and in any case it is a side-channel, usually via an HTTP server.i read the dynamic code downloading using RMI ref. document but one thing i still don't understand
"+if the remote method receives an object instance, for which the remote object cannot find the class definition locally in its CLASSPATH.he class of the object sent by the client will be a subtype of the declared parameter type. A subtype is either:+
+* An implementation of the interface that is declared as the method parameter (or return) type+
+* A subclass of the class that is declared as the method parameter (or return) type+
how can this case occur, and if it does the remote object will look for the class's definition at the codebase of the client , am i right?
The bandwidth utilization of an RMI invocation is a more or less linear function of the size of the arguments and return value, including all non-static non-transient objects reachable from them.if i understand you well , to minimize the consumption, the objects that are to be used as arguments you are talking about should be coded in a way that uses transient and static wherever applicable and possible,and the smaller objects you provide the less bandwidth you use.
am i right ?
Other than that is there any way or any measures that can help in this direction?

1250AP's with 4400 Controllers - LWAPP WAN Bandwidth consumption

Does anyone know and, preferably, have a link on how much bandwidth a Lightweight AP consumes when deployed across a WAN link? I know Cisco keeps saying no more then 8 across a WAN managed by a centralized controller, but I can't find anything specific. Thanks so much in advance.

There's a lot of components in LWAPP packets which will vary according to different situation.check this for LWAPP detail: http://tools.ietf.org/html/draft-ohara-capwap-lwapp-02
actually, A discovery request packet is 97 bytes (including the 4 byte FCS),A discovery response packet is 106 bytes (including the 4 byte FCS), Packet sizes for the join request and response messages will vary based on the MTU supported by the transport(1596 or 1596+1500),The initial exchange between the AP and the WLC (ap-manager interface) is approximately 6,000 bytes and a one-time configuration change averages 360 bytes and involves 2 packets each from the AP and the
WLC's ap-manager interface.An RRM-related information exchange takes place once the AP has been provisioned. A typical exchange
between the AP and the WLC (ap-manager interface) is approximately 1400 bytes. In the event of an RRM-related configuration change, there is a four-packet exchange between the AP and the WLC's apmanager
interface. This exchange averages 375 bytes.The system heartbeat, coupled with fallback mechanism, is 4 packets every 30
seconds and comprises of the following packets:
LWAPP ECHO_REQUEST from AP (78 bytes)
LWAPP Echo-Response to AP (64 bytes)
LWAPP PRIMARY_DISCOVERY_REQ from AP (93 bytes)
LWAPP Primary Discovery-Response to AP (97 bytes).
There are two ongoing RRM exchanges. The first one, at every 60-second interval is the load and signal
measurement and consists of 4 packets. This exchange always adds up to 396 bytes, as following:
LWAPP RRM_DATA_REQ from AP (107 bytes)
LWAPP Airewave-Director-Data Response to AP (64 bytes)
LWAPP RRM_DATA_REQ from AP (161 bytes)
LWAPP Airewave-Director-Data Response to AP (64 bytes)
The second sequence of packets is the noise measurement (including a statistics information request and
response sequence) done every 180 seconds. This is a short (0.01 seconds typically) exchange of packets
and averages 2,660 bytes approximately. It consists of the following packets:
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP STATISTICS_INFO from AP
LWAPP Statistics-Info Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP 00:14:1b:59:41:80
LWAPP Airewave-Director-Data Response to AP
LWAPP RRM_DATA_REQ from AP
LWAPP Airewave-Director-Data Response to AP
LWAPP STATISTICS_INFO from AP
LWAPP Statistics-Info Response to AP.
Rogue measurements are done as a part of the scanning mechanism (for more details, refer to the Auto RF
and Rogue Detection whitepapers) and included in the above RRM exchange every 180 seconds.
The LWAPP data frame header adds 6 bytes to the existing 802.11 packets.
Since LWAPP frames can be fragmented, a Fragment ID field is included and the total packet size can be
determined by adding the original frame and the IP Fragment that follows (It is important to note that the IP
Fragment that follows is not encapsulated in any LWAPP headers).
In conclusion, operation of LWAPP does not introduce heavy bandwidth requirements on the infrastructure and in most typical deployments, there would be no such need to add extra capacity to the infrastructure to accommodate Cisco's Unified Wireless Architecture.

Calculate interface bandwidth through WMI Classes

Hi,
I am trying to find bandwidth utilization percent for all interfaces.
Using Win32_PerfFormattedData_Tcpip_NetworkInterface captured
BytesTotalPerSec and Currentbandwidth and
calculating utilization % = ((BytesTotalPerSec*8)/Currentbandwidth)*100 by this formula.
For some times its been observed that utilization percentage is crossing 100%.Is there any way to calculate bandwidth utilization through WMI.
As perfformatteddata contains all cooked values and currentbandwidth is raw value.Is there any issue with the formula i used?

Alos note this about teh counter called "currentbandwidth":CurrentBandwidth
Data type: uint32
Access type: Read-only
Qualifiers:
DisplayName
("Current Bandwidth")
, CounterType
(65536)
, DefaultScale
(-6)
, PerfDetail
(200)
Estimate of the interface's current bandwidth in bits per second (bps). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.
This is not what you mena bu "currentbandwidth". I think what you are looking for is currernt usage or current bytes/sec.
¯\_(ツ)_/¯

Monitor the consumption of bandwidth

Hi,
I Need help to choose the best solution to monitor the consumption of bandwidth, particularly who are consuming the bandwidth. With the SNMP protocol I can know the consumption of bandwidth but I can't know who are consuming. What are the alternatives?
Thanks to all

If the L3 3750 switch is the gateway for your hosts, it's not very easy to capture flow-level data. Netflow is generally only supported on routers and high end switches like the Catalyst 6k. (Though there is a feature module for the newer 3750X's).
For an ad hoc look at the data, one could span a port and parse the data in a protocol analyzer. That's generally overkill for a simple look at flow patterns though. RMON probes are also possible thought they have generally fallen into disuse in recent years.
Do you really want to look at LOCAL bandwidth consumption (i.e., among ports on a LAN switch)? Folks seldom do that at any level of granularity except in troubleshooting specific problems since LAN bandwidth typically exceeds WAN by an order of magnitude or more and is generally over-provisioned. It's usually much easier to just watch, say, switch uplink utilization in the aggregate and add additional ones (or move servers around logically) if utilization becomes an issue.
Seeing the overall architecture and components of your system would allow us to give a better assessment.

Ea4500 and bandwidth monitoring

Hi.
I have a ea4500 router with 3 pc's, 4 iphones, 2 playstations, ipad, ps vita, house cat, and a printer all wired into the internet. There are four of us in the family all using the internet but I suspect one of us is using considerably more than the other. I live in the country and my current isp has us on the max available account - 50 gigs / month. Lately we have been hitting 45 in less than 3 weeks into the month. I would like to know which of the things connected or which person is using the most of the bandwidth up. Is there a program that doesn't require a phd in quantum physics and networking that can monitor this for me and spit out a report on who or what is the hog here?

Bandwidth monitor does not come handy with this device. However, you can dig a little deeper through Google to find third party software that could monitor bandwidth consumption for every device inside the network. I found one that monitors the bandwidth consumption of each application installed on my computer. This one only monitors one computer not the network. You might be able to find a network monitor if you dig a little dipper through the net.

Strange network bandwidth management

Hi,
I've noticed some strange behaviour of Remote Desktop Services.
I have remote Windows Server 2012 R2 running in data center. There is 100 Mb/s download / 100 Mb/s upload internet link tested with speedtest.net. I have also two laptops with Windows 8.1 in my office running on 25 Mb/s donwload / 3 Mb/s upload link. One
of the laptops has 1280 x 800 screen resolution and the second one has 2880 x 1620 pixels.
I tested the connection speed by downloading 2 GB file from Windows Server to my laptop. File was downloaded with 25 Mb/s speed as expected. So the connection is perfectly OK.
I've configured our application as RemoteApp on Windows Server and have been testing this environment on my laptops. Some modules of our application are "rendering intensive" - they change some big portion of screen 10 times per second. And
here the problem starts.
When I test RemoteApp only on my low resolution laptop all work great. RDP protocol utilizes about 1 Mb/s of bandwidth.
When I test application on my high resolution laptop RDP protocol utilizes about 5 Mb/s of bandwidth and application presents very low frame rate (1 frame per second maybe). I don't know why this happens. I have 20 Mb/s link and only 5 Mb/s is being used
by RDP.
And magic happens...
When I start my RemoteApp on both laptops frame rate is perfect on both of them! Windows Server is uploading 14 Mb/s (1 Mb/s to low resolution laptop and 13 Mb/s to high resolution one). It streams 6 Mb/s more to high resolution laptop than in "single
laptop" scenario! When I close or even minimize (!) application on low resolution laptop the frame rate on second laptop degrades. When the application is resumed, frame rate goes up.
The same behaviour is observed when I run RemoteApp on high resolution laptop only but I connect through RDP to my Windows Server and turn on session shadowing. I observe my laptop's session through shadowing and frame rate magically goes up.
It's strange that streaming RDP sessions to two laptops produces better experience than doing it only for one client. I'm able to reproduce this behaviour every day, every time in two locations with different internet service providers.
I turned off all magic fair sharing (disk, CPU, network) on Windows Server but without any success. The same about turning off UDP connections or connecting with and without RD Gateway. I think that there is some magic algorithm for resources management
that is causing it. I've been searching internet and testing different scenarios for week but without any luck.
Have anybody seen something like this? I would be very grateful for your help.
Wojtek Małota

Hi Wojciech,
Bandwidth consumption when using RemoteApp programs could increase and decrease, depending on the application and its usage, when compared to using a remote desktop. There are lot of factors which can be taken into considerations when measuring performance
for RemoteApp\Desktop. You can go through below article for detail as also there is RDP performance whitepaper to understand clearly.

Did you know? (ATV power consumption)

leaving your Apple TV connected to a power source when not in use will cost you $7.65 a month in hydro cost (based on prices for Hydro in Vancouver Canada.
I am testing the consumption through our Hydro smart panel at home and will post the results as they come.

Where do you get the 17-22 watts from?. My
measurements are quite a bit higher than that. Do
you pay tax on your Hydro we ave delivery charge and
14% tax on top of this.
See the link for the source. Not terribly reliable, just some guy in a discussion forum. It would be nice to have a clearer picture of the power usage, so if you've got some readings you could share, that would probably be helpful.
This seems like the kind of thing that ought to show up in Apple's tech specs: <http://www.apple.com/appletv/specs.html> All it says there is that the device has a "48-watt universal power supply." I'm not sure, but I'm guessing that means that it can never consume more than 48 watts.

In time Consumption of Raw material in case of Subcontracting

HI Gurus
Please look into the following issue.
Presently we are sending Raw material to subcontracting vendor through 541 mvt type along with excis challan.Then subcontractor intimates raw material consumption details time to time through mail/fax.Now as per client requirement raw material consumption should be done in time i.e. when they are receiving raw material consumption details. They don't want book the raw material consumtion at the the time of receipt of finish goods.
Please guide me to book in time consumption of raw material.
Redards
Kumar

Thnks for your reply.
I want to do the manual consumption from subcontracting stock. Client don't want to book the consumption at the the time of raw material transfer to subcontractor. Also there will be problem in subcontracting challan reconcillation.
We can't do the manual consumption through 543 mvt type .Is there any workarround for this ?

Questions about the bandwidth.

Let me explain my existing environment
as follows :
- I have two 2801 routers with
C2801-SPSERVICESK9-M IOS
- Each router has Four-port FXS
connected to the phones
- The bandwidth between these routers
is 256 Kbps ( Leased Line )
My qouestions are as follows :
1. How many bandwidth are a call
comsumed ( per call ) ?
2. To ensure that the bandwidth of
VoIP is not excess the maximum
bandwidth of leased line. And to
ensure that the priority of VoIP
is always higher than the priority
Data. I will use RSVP and CBWFQ
with ip precedence. Are these
features suitable for the
situation ?
Thanks!! : )

hi
regarding bandwidth consumption it depends upon the kinda codec which you are gonna use up there.
ofcourse g.729 does uses minimal amount of bandwidth and also that get reflects in ur quality.
If you are gonna used some kinda RTP compression out there that can always reduce the packet length drastically to lesser size which will be easier as well u will be able to use the B/W effectively .
regarding the priority part you can always use up LLQ to have high priority for your VOICE traffic and deploy CBWFQ for your data traffic.
if u wanna have sample configs would suggest to do a search in cisco about the same ,if u need further assistance do revert..

CS-MARS bandwidth utilization

Hi,
I know this product is end of sales and end of support by Cisco now. However appreciate if some MARS experts can guide me how to generate a bandwith utilization report on CS-MARS (like bandwidth consumption on switches based on interfaces) and what are bootstraps to be available in order to generate this report.
thanks..

From what I can tell, it displays 0.0.0.0 because the event was not triggered by the inspection of a packet with source and destination address or the source/destination cannot be derived from the logged message. For example, the event "inactive reporting device" from Mars does not have a source address and therefore displays 0.0.0.0.
Is this correct?
