Cisco Network Assistant (CNA) Error: Connect

Best regards community,
Please I need your help, I installed Cisco Network Assistant 5.8 (9.1) for manage some catalyst switches as 2950, 2960, 2960S, 2960X, 3750X. I can manage all devices except WS-C2960X-24TS-LL model, I have following message from CNA: "Error: Connect Index: 26, Size:26". This device have same configuration for level 15 access as other devices with user name and password. the catalyst switch IOS version is 15.0(2)EX4
This problem is about either software or hardware? How can solve?
Thanks in advance

You're welcome.
I know the product team monitor the Network Management Forum. If you post your question there, one of them may pick up on it.
The CNA support typically lags the new product release by about 4-6 months, sometimes longer depending on how well the hardware product release matches up with the network management product's latest release date. The 2960XR just started shipping in July 2013 so a good guess would be that CNA might support it in the next release (5.9?). That's just a guess though.

Cisco Network Assistant(CNA) not connecting to access points.

When I create a community with CNA, it finds the 2960 switch and connects to it. However it shows "connection failed" for all the 702i access points. Not sure why it shows connection failed. Any help would be appreciated.
Also, if I try to connect directly to the access point thru CNA, it says not accessible.
Thanks.

It will be helpful for other community members to know the solution and cause, if can be shared.

Cisco Network Assistant access error

Dear all,
I've just installed Cisco Network Assistant (CNA) on my Windows 7 laptop but whenever I try to start it I get an error message as shown below:
Read/write access problems:
Access is denied
=======================================
Note: Read/write access is required for user home directory and installation directory:
C:\Users\...........
C:\Program Files (x86)\Cisco Systems\Cisco Network Assistant
=======================================
My Windows is 64-bit.
Any ideas on how to sort out this will be appreciated.
Regards,
Davis M Onsakia

i had the same problem and i wasn't willing to open the whole of the programs directory to what username cisco used when installing or when run, so i opt'ed to install in a root directory, make c:\cisco and install there, that way if there's a permissions error I can add what I wanted, but thats how i got mine to work. Install in a different directory, one that you can add read/write permissions to.

Cisco Network Assistant (CNA) 2960X Support

Hi Folks,
The 2960X datasheet indicates that it supports Cisco Network Assistant (CNA), but when I tried it with CNA 5.8.7 it was not compatible. The release notes for 5.8.7 did not include the 2960X as a supported device.
CNA 5.8.7 Release Notes:
https://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/qa_c67-577519.pdfhttp://www.cisco.com/en/US/docs/net_mgmt/cisco_network_assistant/version5_0/release/notes/OL12210a.html
Can someone confirm if CNA will have support for the 2960X series in the future and if possible provide some guidelines on timing?
Thanks,
Chris

Cisco Network Assistant (CNA) 5.6 is launched

Hi Netpro community! I am very pleased to announce the general availability of Cisco Network Assistant version 5.6.
While we wish CNA was available sooner, we know there is a lot of pent up demand for device support for the 2960-S, 3750-X, and many new 4k devices. Even without a release for approximately 18 months, CNA had over 100,000 downloads in 2010 and 2009, and we hope to see that number climb with the popularity of Cisco's new fixed and modular switches. Thanks for your patience and we hope you enjoy and utilize the simple, intuitive network management CNA provides.
If you have any feedback on the product or questions, please feel free to contact me at [email protected]
Bob Krentler, product manager

Hi Robert,
I think your initiative to post a message here, anouncing a new version, is a very good one.
I have had multiple times where a new version of a product had appeared on CCO but I missed it.
A generic place (feed) where new NMS releases are anounced would be quite helpfull for me.
Cheers,
Michel

Cisco Network Assistant Will Not Connect to 3825 Router Using http

Trying to use the CNA to connect to my 3825 router, in preparation for 2960x switches we are going to purchase. I cannot connect using http - read/write. It seems as though the username and password fail. I can however, connect Read – only Level 1, and the username and password work fine and I am logged in. Is there something I can check in the Router configuration for the Network Assistant to work?
Thanks

Cisco Network Assistant cast error (vlan)

Hello,
As we have a new Catalyst 2960XS PoE in our network I upgraded the CNA 5.2 to version 5.7 (6) keeping my old configuration. Then I added the 2960XS and it is working fine. But now, when I try to configure any port's VLAN of one of our old switches (Catalyst 3508G-XL and both of our Catalyst 3548-XL) I am not able to do it anymore. It just shows the error this message :
Error: Modify Port Mode com.cisco.cpnm.features.dsbu.c3500.vlan.C3500Vlan cannot be cast to com.cisco.features.dsbu.defn.vlan.CommonVlan

Hello,
We have the same error message with CNA 5.8(6) on Cisco Catalys 3548XL IOS 12.0(5)WC17.
Error: Modify Port Mode com.cisco.cpnm.features.dsbu.c3500.vlan.C3500Vlan cannot be cast to com.cisco.features.dsbu.defn.vlan.CommonVlan
Is there any workaround ?
Thank you

Cisco Network Assistant MAC auth issue

I have few Autonomous Access Points all managed by the Cisco Network Assistant. Users have access to wireless only based on MAC authentication.
Every once in a while the wireless access to the Access-Point fails and the following error is showed in the Cisco Network Assistant.
ERROR: The MAC address filter 700 used for association access was not created by the web interface and cannot be displayed.
also
WARNING: Filter 700 was configured on interface Dot11radio 0.170 using CLI. It must be cleared via CLI to ensure proper operation of the web interface.
The Network Admin does not use CLI but this problem keeps coming. To fix this problem I had cleared the access-list 700 via CLI and created a new access-list 700 via Cisco Network Assistant. Adding all the MAC's each time the network goes down is a cumbersome process. Is there a solution for this?
Thanks in advance
error snapshot attached.

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.

Cisco Network Assistant and add to comunity problem via HTTPS

hello,
i have big network of cisco switches and all is in my cisco network assistant in comunity connected via HTTPS. if i add new switch to network (all for HTTPS access is configured good: domain name, ip http secure-server, authenticate locale ...) and if i can add this switch to comunity (right click on icon and ADD TO COMUNITY), CNA say "Unable to Connect", because it can connect to switch via HTTP (i have disable it on switch), not via HTTPS. i have never version of CNA ... where is problem? why it not connect to switch via HTTPS? hmmm? thank you ... Peter

You can put an access-list on the http server if you are concerned about security exposure.

What's the username & password when i connect device from cisco network assistant

what's the username & password when i connect device from cisco network assistant?
http://i200.photobucket.com/albums/aa273/wallfire02/Capture_zpsa8f5fd2b.jpg

Although that may be true...
If I click the "Connect As..." button it asks for a username and password.
I've experienced connecting to other user's computers on a network. To gain access to their computer, I just use their username and password. I've done this before to transfer files without using a flash drive or burned disk.
I'm trying to find out what I'm supposed to log on as to gain access to this device...
My point is that yes, I'm connected to it by wifi. Otherwise it wouldn't show up; ha-ha!
Is my point really that hard to grasp?

Cisco Network Assistant 5.5 and WS-X4013+10GE

I have installed CNA 5.5 and it works fine with most of the devices, including catalyst 4500 series with different supervisors (WS-X4013+, WS-X4013+TS, WS-X45 SUP6-E).
It can also detect supervisor WS-X4013+10GE, but CNA failed to show this device in Front Panel View. Is there anything I have to do to make the devices with Supervisor WS-X4013+10GE to be shown in Front Panel View?
WS-X4013+10GE are in either 4503 or 4506 chassis, running IOS version 12.2(31)SGA or 12.2(40)SG.
Please give some hints, thanks.
Rgds,
Sunny

I downloaded Cisco Network Assistant 5.5, everytime when I try to run
I get error message "Could not creat Java virtual Machine' any idea how
to solve this?
To overcome this problem, open the file C:\Program Files\Cisco Systems\CiscoSMB\Cisco Network Assistant\startup\startup.properties (the default installation path), and modify this entry:
JVM_MAXIMUM_HEAP=1024m
Replace 1024m with a lower setting that does not exceed the available RAM. There is no way to foresee what value will work. Try 512m, and lower it further if necessary. You can use the dial peer tag range 2500 to 2999 out-of-band to define your own dial peers.

Cisco Network Assistant access

Hi,
I installed cisco network assistant, but when I try to import a device by entering a specific IP address (HTTP), it prompts for username/password but it doesn't accept them. The weird thing is that when I enter a specific IP address for a switch device, I can access it through CNA.
What exactly shoud I look at the devices' configuration that I cannot access?
Thank you.

The device that works in the CNA doen't have the "ip http authentication" enabled. It seems that this is not the issue. When I enter an IP address to the "Connect to" prompt and select the HTTP protocol and Access-mode "Read-only", it prompts for Username/ Password for "level_15_access", but it doesn't accept them.
