Interface VLAN Bandwidth Utilization Reporting
I am currently evaluating a few products for Network Management and Monitoring. The question i have is, how is % utilization calculated for a virtual interface? Some tools have reported that one of our interface vlans is at 320% utilization. Obviously, this is not accurate. If anyone can give me advice on how to accurately report interface utilization percentage on a virtual interface, I would appreciate it.
No, changing the vlan speed will not influence the physical interface's speed.
So, no need for that.

Generate Prime Interface Availability and Utilization Report for unified APs
Hi,
I´m trying to generate interface availability and interface utilization report for unified APs on Prime Infrastructure 2.0, but it doesn´t display any information. I have created device health and interface health templates under desing/Monitor configuration/My templates and deployed under Deploy/Monitoring deployment, but it still don´t show any information,
thaks for your help.Hi Alejandro,
Did you solve this problem? Or is it a bug?
I face the some issue with you, I just run "Report/Report Launch Pad/Deivce/Interface Utilization"
and then I create a report for interface utilization.
But it display nothing when the report run finished.
I ask some guys in this forum, they said maybe it's a PI2.1 bug.

LMS 4.2.3 Query on Interface utilization report
Hi All,
Interface Utilization report displays the interface utilization data for each device polled for the Interface Utilization
template. The information is presented using the percentage specifier.
For eg its displayed % (Rx Max%,Rx Avg%,RxMin%,
Tx Max%,Tx Avg%,TxMin%)
I wants report should have the data(interface utilization In Bytes of data)
Can we display the data instead of the percentage?? is it possible ???
Regards,
ChannaHi Channa,
log into dbreader using the following::
http://servername : 1741/dbreader/dbreader.html
or
https:// servername : 443/dbreader/dbreader.html
user Id is DBA
Database Name is upm
password :: user defined (by default password is c2ky2k)
1. Here is the query to get the pollerwise managed MIBObjects:
"select count (*), PollerName from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId = b.PollerId and b.Poller_State NOT IN (1) Group by b.PollerName;"
2. Here is the query to get the total mibobject count for the active pollers
“select count (*) from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId =
b.PollerId and b.Poller_State NOT IN (1);”
Hope it will help

LMS 4.2 specific interface utilization report
Hi,
is there a way to create a interface utilization report only for a specific port? Like switch1->interface fa0/10
Right now i can only choose all ports from a device?
Thank you.
ChrisSo, the new weekly report does not show the high Utilizations anymore, but there is a new problem:
In the "Report Details", there are 7 devices and 126 interfaces, but in the "Interface Utilization Summary", there are only 49 Interfaces.
I have added a screenshot, so that you can see, what I mean. -
EEM Applet - Interface bandwidth utilization
We are planning to get syslog or snmp alert for bandwidth utilization of Uplinks by EEM applet, can any bdy help me on that?
We managed to get alert for input traffic but we are not able to get alert for total bandwidth utilization ( input + output ).This is possible with an EEM applet. I have done it on G1 ISRs with 15.1. The applet is here:
http://ephemeralportal.blogspot.jp/2014/01/eem-applet-teach-your-router-to-monitor_24.html
I usually run 12.4 on 3745s in GNS3 and they do not have the action set to do variable manipulation, so I am guessing that this is a newer feature, although I could not find what minimum version you would need on a quick search. -
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? -
Interafce utilization report in lms 3.1
Hi I have installed LMS 3.1 at ine of our customer. when we are extracting interface utilization report(HUM interface report) It gives me the graphs which are in format of packets/second or value in % . Customer want a simple report which will give him the graps in bite or Kb per second. even if when the operator will pull the report the report should be generated simplly port utilization for both RX and tx in Kb or Mb insted of octate/packets per second.
Is it possible ? if it is possible please guide me how to configure the report template.Hi Joe,
Can you clarify if this is correct
( Avg % Rx + Avg % TX ) x Total Bandwidth configured on interface/100 = Total Bandwidth Utilization
For eg: Avg % Rx=11
Avg % Tx=11
Interface= Gigaethernet 1/1
Bandwidth 465000
Bandwidth= 465000= 46.5 Mbps
Now Applying formula = (11+11) x 46.5/ 100 = 10.23 Mbps i.e actual interface utilization

Ciscoworks 4.0, Bandwidth Utilization
Hello!
I haven't worked with Ciscoworks in a long time and see v4.0 is out. Does anyone if this app is a good tool to monitor bandwidth utilization? We need a good product that can monitor utilization on our WAN circuits and also doing regular backups of our configs for a variety of routers, switches.
Your opinions are appreciated!
BenMy opinion may be biased, but LMS 4.0 can do what you want. It has performance management capabilities that can graph and report on interface, CPU, and memory utilization as well as allows for custom MIB object pollers to be defined. LMS also does configuration collection for a wide variety of devices.
If you really want to get a good idea if this is the right product suite for you, download the 90-day eval from http://www.cisco.com/go/nmsevals (click on the Network Management Software link). You will be able to test the full functionality of LMS 4.0 on up to 100 devices for 90 days. -

As you can see I've got InBandwidth>100%
Why it so?
If I change ifSpeed from 2000000 to 2048*1024 bits per second (right value for E1 interface) it doesn't give me InBandwidth<100%
In attachment you can find a part of gateway configYou may keep on cracking your head against equations, it's up to you. If I were you I would have already installed Oracle 10g Grid Control and I would already have configured a 6 month retention period for the performance statistics and setup a report of resource consumption.

Prime Infrastructure (2.0) utilization report on port group possible?
Hello
I want to create an interface utilization report for a specific port group in PI, but can't see how to do that in the report setting. You only seem to be able to select a specific device or site rather than port group. Is it possible? Also, is it possible to put that on a dashlet?
thanks for your helpThanks for that Mahavir
Yes, I worked that out a little while ago, and can now see interface utilization by port group on the Performance > Network Interface page. I do have another question however (well two)....
I wanted to add graph over time for the utilization to the detail dashboard, but nothing shows up, even though I see the utilization in the network interface page, so I'm sure the monitoring is deployed. Why is the data missing from the graphs?
Also, I wanted to see interface packets per second graphs, but see that is not part of any default template, so I created a customer SNMP template from the IF-MIB to do this, but I can only deploy that against sites/devices or a list of interfaces, and not port groups. Why can't I deploy a customer SNMP template against a port group?
thanks for your help -
Why is there no updates to the firefox throttle add-ons ? Is there an alternative? throttle is Bandwidth utilization throttling and monitoring extension for Firefox
Well, it's probably one of two things: either the awesome dude(tte) who developed this awesome extension was tired of updating or the changes in FFox software architecture carried out between version 3.x and 4+ created challenges that were too difficult for him to surmount or a combination of both. Honestly, I love Mozilla but I think they dropped the ball on the throttle issue. It's such an obvious and necessary function and it's so easy to implement. They should have included it a long time ago as in built feature. And, if you are browsing and looking at this post and you agree. Add a suggestion in mozilla.org. The more of us asking for this function, the better.
Meanwhile, I have the following solution for you:
Solution 0.6.9.23.11 (DIY Version of my Solution ):
Setting Up a Separate Portable Firefox 3.6.x that runs independently of and simultaneously to your latest version of Firefox
Get FireFox Portable 3.6.24:
http://portableapps.com/apps/internet/firefox_portable/localization#legacy36
It's a portable app, meaning that it's got all it's profiles and preference and application files in the same directory. It won't compete with your current installation of Firefox, has it's own separate extension folder etc...
Get Firefox Throttle 1.1.6
http://firefox-throttle.en.softonic.com/ (I couldn't find it in the official mozilla site)
It will be flagged as incompatible with even that old version of firefox (but it isn't). You just need to turn off compatibility checking. You can do that with this extension:
https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/?src=search
If you have Bookmarks you want to port to the portable (bad pun intend), backup them up to bookmarks.json file on your desktop and import them to the portable version. You can export/import more stuff using FEBE addon but that's a whole world of headaches if you don't your doing.
Many of your extensions favourites extensions will no longer work on FFox 3.6.x but if, in that same addon's page, you look around until you find a link to previous versions of the addon, you will notice that the compatibility info is right below the version numbers. Just download and install the latest version that is compatible with you 3.6.x....
Voila mon ami! Your FFox 3.6 portable has just become your own private Download Mule whom you can throttle to your hearts content (ever throttle a real Mule??? I wouldn't try it, personally...) Do your regular browsing in another (unthrottled) browser and do your big downloads in the Mule...
If you want to keep using your brand spanking new Firefox for other types of browsing while using this portable Mule edition for the downloads, just add -p -no-remote to the shortcut leading to your Firefox Portable Mule edition.
For example, my taskbar shortcut to my Firefox Portable is:
""C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe"
I just changed it to:
"C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe" -p -no-remote
This will make it occupy it's own independent instance and I can use the both my Firefox Nightly and the Firefox Portable editions at the same time (each one, using a different profile ie. extensions, cookies, password, cache etc).
If you're on Linux, you can just run this on Wine and set the Windows Version to Windows 2000 in the Wine config,
If you want to get rid of the Portable Apps splash screen, click here:
http://www.ghacks.net/2011/06/06/getting-rid-of-portableapps-splash-screens/
Solution 0.6.9.23.11 (Non-DIY Version of my Solution):
Download my preconfigured but SWAGGED-THE-HECK-UP PortableFirefox 3.6
Having realized that some of you may find the above to be daunting. I took my own customize firefox portable, took out all my data and compressed the folder (it's portable, so it'll run as soon as you unzip it).
Here is a screenshot:
http://www.mediafire.com/?o95nkwo8y6q535j
Here is the download link:
http://www.mediafire.com/?xdw87ivf3184u2s
Don't forget to modify your Start/Taskbar shortcuts:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe"
I just changed it to:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe" -p -no-remote -
Top Wireless Client Bandwidth Utilization on WCS?
Hi, there.
Can I get the top wireless client bandwidth utilization info / report from WCS? I would like to know how high they can reach, and how many are those 'power users', so far I only find "Busiest Clients" but not quite certain sure about the meanings of the "threshold" and "utilization' besides, the minimum interval is 1 hour, which seems to long for me, I would like to have some data like MRTG which is in 5 minutes range, thanks.
LeoWelcome to the discussions!
There is no "relay" function in the "extend a wireless network" setup. Each AX that is set to extend communicates directly to the Time Capsule and not to another device that might be between it and the Time Capsule.
If you need the "relay" function, your only real option to setup the WDS configuration to see if that might work better in your circumstance.
When you say that you have one AX setup as a client only, this implies that it is set to "join a wireless network". In the "join" setting, the AX only receives a wireless signal, it does not "extend" or rebroadcast the wireless signal. You might want to try setting this device to "extend" to see if that might help the network performance. -
Cisco Prime LMS 4.2- Bandwidth utilization
Dear Experts,
Is it possible to monitor port level bandwidth utilization like how much b/w currently using.?
If we generate report, it gives only percentage, can we change it to bps or mbps.?.Hi Enea,
The size of the DB is huge now, you can try to do a Force Purge
go to Admin > Network > Purge Settings >IPSLA data Purge Settings
see if it helps.
If not then the last resort is to Re-initialize the IPM database.
here are the steps:
1.stop the daemon manager
2.
/opt/CSCOpx/bin/dbRestoreOrig.pl dsn=ipm dmprefix=Ipm (linux/solaris)
NMSROOT\bin\perl.exe NMSROOT\bin\dbRestoreOrig.pl dsn=ipm dmprefix=Ipm (windows)
3.start the daemon manager
Note: If you Re-initialize the database then you need to create the collectors again .
Thanks-

Measuring Bandwidth utilization on 3005 Concentrator
I am looking for an easy way to measure utilization on a site to site vpn configured on a 3005 concentrator.
Help?This can be done using MIBS. The two MIBS listed below give you the total number of octets sent out or received every 5 minutes. You can manually calculate the difference to figure out the utilization.
.1.3.6.1.2.1.2.2.1.10
ifInOctets OBJECT-TYPE
-- FROM RFC1213-MIB
SYNTAX Counter
MAX-ACCESS read-only

interface, including framing characters."
::= { iso(1) org(3) dod(6) internet(1) mgmt(2) mib-2(1) interfaces(2) ifTable(2) ifEntry(1) 10 }

On tunnel interfaces, a different set of MIBS called "ALTIGA-MIB" need to be used. I feel you should also have a look at the document "How To Calculate Bandwidth Utilization Using SNMP".

Hello,
Is there a way to look at the bandwidth utilization on a per port basis on the 3750 switches? Trying to track down a possible issue remote;y and nothing like WireShark is onsite.
Thanks in advance.
All replies rated.You can enter "show interface summary" to see the tx rate and rx rate for each port. Very easy to read format.
To use wireshark remotely, you could always use ERSPAN, which would send the monitor session to a remote switch. If I'm not sure of the commands I'm entering on a remote switch, I normally do a "reload in 15". In case I lose connectivity, it will reload in x number of minutes to restore service. Save you a commute to the remote site to restore service. Just don't forget to cancel the reload when you are finished.
https://supportforums.cisco.com/document/139236/understanding-spanrspanand-erspan#comment-10119266
If you have network monitoring software, it should show the top talker along with the ip address.
show arp | i x.x.xx
this will return the mac
then enter show mac address-table address xxxx.xxxx.xxxx
this will show the interface that learned the mac.
show cdp neigh to verify the port isn't connected to another switch.
Keep entering sh mac and sh cdp until you locate the port with the mac of the top talker.
You can shut the port and see if the trouble goes away.
Just be careful when shutting ports. Its easy to shut the wrong port and lose connectivity.
