Bandwidth monitoring on a Catalyst 2960

Hello all, I'm working with two Catalyst 2960 switches and I would like to know if there is a way to monitor bandwidth on individual ports. Ideally I would like to have one graph showing a bandwidth usage reading on each port. I tried using the Network Assistant to accomplish this, but I was only able to view one port at a time. I also tried using a traffic graphing program from Paessler, but a MIB file is needed to allow the program to connect to the switch. When I ran a search on the network management page the 2960 was not on the list for MIB supported products. Is this type of graph possible to do? Or is there a more effective way to accomplish what I would like to do. Any ideas or suggestions would be helpful.

Hi, we have just swapped all our avaya switches with catalyst 2960 (12, 24 and 48 ports) and 3750 (48 ports with 10gig module).
How do I find what port I should monitor for bandwith graphs?

MIB Extension - Cisco Catalyst 2960 -

Hi everyone,
I would like to monitor a cisco catalyst 2960 provided with IOS v15. I accessed mib files and I found that many component are disabled or have no entry in it (check attachment).
So my question is : Can I extend the mib to support more OIDs ? and if so, I'll be glad if you give a tutorial or example !
Thank you so much.
Best regards,

Your ipRouteTable and EGP MIBs are disabled because the 2960 is a layer-2 switch only, so it does not have any ip routing or EGP. The MIBs will be disabled for features your switch does not support.

Bandwidth monitoring on 3750

im looking for a way to monitor the bandwidth and graphically identify the real time traffic on several ports in our network.
The tool would have to run on a windows workstation which woudl have multple NICS connected to cisco 3750G switches setup wtih SPAN sessions.
the data received should be separted and displayed in real time graphically.
Kind of like what Perfromance Monitor would do.
Does anyone know of such a tool
thank you in advance

Cisco Network Assistant MAC search in Catalyst 2960

Hi,
Since I updated a Catalyst 2960 switch to IOS version 12.2(55)SE1 I can't do searchs by MAC address, when I do "Monitor->Search" the following error appears:
"The software version of the selected switch does not support some of the CLI commands in read-only mode for this window. You must have read-write access to this switch to display complete information in this window"
If packets are captured you can see that the issued command by the CNA host is "GET /exec/show/mac-address-table/", the answer from the switch is:
"show mac-address-table
^
% Invalid input detected at '^' marker.
If I do "Configure->Switching->MAC Address" instead I get the mac address-table correctly. In this case the issued command is "GET /exec/show/mac/address-table/dynamic" and no error is displayed, the answer from the switch is the list of mac-address table.

I have some site admins that use CNA. I just upgraded their LAN to 3560v2 switches running 12.2(58)SE2 and had them upgrade their CNA software to CNA 5.7(6). They reported the same error.
I think you clearly indentified the problem. At one time the IOS command parser accepted both "show mac-address" and "show mac address". At some point IOS stopped accepting the older "show mac-address" format, and CNA is still issuing this command regardless of the IOS version it is trying to manage.

Catalyst 2960-x Tel 1 and g49, bug

Hi Cisco Community
I am experiencing a very strang bug or it's just a "feature". We are setting up 3 Catalyst 2960-x (EX5) as a stack. Te 1/0/1 and Te 2/0/1 are bundled as Etherchannel. (works fine "In-channel-group")
But we just can not connect anything else to Te 1/0/2 or Te 2/0/2.
When i checked the "sh run" i noticed that there are the Ports g49 and g50. What should be Te 1 and Te 2.

Inserting a Flash video and the Bandwidth Monitor

I am new to Captivate, and I want to be sure I'm following
some practical guidelines for inserting Flash video in my Captivate
slides.
I know there are quite a few variables relating to practical
bandwidth usage--basically, we are creating elearning presenations
that will have "talking head" videos embedded within. These
presentations will be available for download via our LMS site, both
within the US and overseas.
I have utilized Captivate's Bandwidth Monitor to gauge the
bandwidth hit each video slide is responsible for. However, I don't
believe the numbers I'm getting back: because I've set each
embedded video to "Pause slide till end of video", all the slides
are reporting the same length in seconds, KB per sec and Video KB
numbers.
Can someone suggest a practical method for setting up the
videos such that the Bandwidth Monitor can interpret them
correctly? Can you also suggest a rule of thumb for maximum length
for each slide with an embedded video (320 X 240) in it?
Thanks in advance,
Carl

Is Bandwidth monitoring possible?

Hi,
I wanted to monitor my internet usage. Is it possible to build a bandwidth monitoring application using ActionScript 3.0 (with AIR + Flex).
Aim:
Get total downloads and uploads going via ethernet.
(If possible display the list of ethernet cards and wifi cards and the user can select the one needed to be monitored).
Also get the time of connection.
+(optional)
Automatically monitor if any transfers goes any ethernet or the ethernet after selecting the specific one thereafter.Any resources or any ideas regarding the above.
Thanks.

Dear Siva,
we did nearly the same in LV 4.0 times where the G Webserver was not integrated into LV. The only difference is that we used a java applet instead of javascript. It was running fine with Netscape 3 and Internet Explorer 4 on Win NT 4 machines.

Troubleshooting Fiber Connection on a Catalyst 2960

I am trying to test my fiber connectivity on a Catalyst 2960 before I deploy it. So what I thought I would do is connect it to another switch in my office with a open port for the fiber connection. The other switch is a Catalyst 3560G. Here are the port configurations:
interface GigabitEthernet0/2
switchport trunk allowed vlan 1,100
switchport mode trunk
macro description cisco-switch
interface GigabitEthernet0/25
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,100
switchport mode trunk
The first one is the catalyst 2960 and the 3560G is the second.
When you show the interface for each of these it shows that it recognizes the media but the line protocal and the GigbitEthernet Port is down.
Any Ideas?

Sorry... a fiber optic cable with a connector on each end.
To aid in troubleshooting, many times we loopback the signal back to the originating device. An optical loopback is just connecting the transmit (Tx) to the receive (Rx).
The multimode SFP/GBIC transceiver you are using will allow you to directly connect the Transmit and Receive ports without damage to the unit. This should provide you with a green link LED.
If so, then you can reconnect your fibers and loopback (connect the two fibers together) at the far end of the fiber link (use an optical adapter) and see if you get a green LED.

Catalyst 2960 Problem with Cisco SPA512

Hi there,
I hope someone can help me.
I don't have much experience with switches, I'm doing the desktop support in our company.
We have Catalyst 4510 R+E to 2 Catalyst 2960 switches and seperate VLAN's for IP Phones and for Internet in one part of our office.
Now I'm running into trouble with some IP Phones that are connected to the 2960 switches. It appears only to happen with Cisco's SPA-512. I've tried FW 7.5.2, 7.5.5 and 7.5.5b. These phones sporadically drop the call / connection, with the red MIC button blinking. Based on my research this means that it looses Internet connection. I have 1 SPA512 with FW 7.5.1 that does not show these symptoms.
I have other phones SPA942 and Polycom IP335 in the same area behind the same switches and no issues.
We've tried to disable auto negotiate and set a fixed transmition rate or either 1Gbps and 100Mbps, both without success.
I also have SPA512 in other areas of the office just connected to our Catalyst 4510 R+E and they work just fine. That's why I don't believe it has anything to do with the 4510, but I can be wrong.
That's all I have for you guys. Hope someone can help me to fix / troubleshoot this..

Gbic loop on catalyst 2960

Hello,
I would like to know if there is a way to validate that a SFP type 1000baseLX is working properly on catalyst 2960.
I am looking for the loop feature that is available on routers.... but not on switches.
The topology is 2 catalyst 2960 switches with both SFP type 1000baseLX connected together with a fiber. This was working find but actually, the two interfaces are down/down.
The idea is to be sure that the problem is on the fiber and not on one of the SFP....
Thank You for your help.

UniDirectional Link Detection (UDLD) addresses your concern regarding the fiber. See http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_46_se/configuration/guide/swudld.html for more information.
For the SFPs themselves, you might want to review http://www.cisco.com/en/US/products/hw/modules/ps4999/products_tech_note09186a00807a30d6.shtml for more information.
Hope this helps.

Installed wrong image on Cisco Catalyst 2960

some time ago I did an IOS upgrade on the Catalyst 2960, however I used the wrong image and caused the switch CAN NOT load properly. My switch is c2960 but I used c2960s, what a big mistake.
When the switch boots, and it hangs on the execution of the image, because c2960s image will not work on c2960.
Anyone got some idea how I can fix this? I tried to restart the switch and pressed "Break" on the terminal, and it didn't stopped.

Cisco SG300-28 / SGE2000 / Catalyst 2960

Hello everyone,
I'm looking for switch to accompany Cisco ASA 5520 in data center, with 20+ GE ports and no need for PoE.
I would like to understand the difference between Cisco SG300-28, Cisco SGE2000 and Cisco Catalyst 2960, 2960-C and 2960-S Series (except specific number of ports). As far as I can see the Cisco SGE2000 has 4x SFP and is stackable unlike the SG300 with 2x miniGBIC/SFP, but not much else. Cisco Catalyst 2960 series offers some additional features like USB storage, but I can't imagine I will need that.
Any suggestions?
Thank you
Dan
