ESW-540-8P, http connection and browsers

Howdy,

Portal: cisco-onplus

VAR: 1913

Customer: 5651 (USS Nautilius, SSN-571)

Version: <Today> with On-100K9

ESW540-8P in network with default settings. Objective is to connect using OnPlus http proxy to device http management (kubrick) I/F and edit settings.

Per the device compatibility listing for ESW540, I set http (port 80) as connection method and enable "fix headers".

Using locally connected PC, I have verified that I can establish http connection directly (no OnPlus proxy) using Safari, firefox and IE browsers on multiple platforms (2 win 7 PCs (FF, IE, Safari), 1 iPhone4.(Safari).  In all cases, I am able to establish http connection, login to the ESW540-8P and perform remote operations on the device http UI through the browsers UI.

However, when I attempt the same when connected remotely through OnPlus, I get different success/failure behaviors depending upon the browser I use.

When I use Firefox or IE, as soon as I click the "Connect" button on the device modal, a browser window is launched as expected.

For IE (IE7) on both Win7 PCs, about ten seconds after the window launches, the device UI presents its login screen. I supply credentials for the login. Shortly thereafter, a partial rendering of the primary "status" page for the device is presented on the browser UI. I can see the CSS styles paint, but I see no text, there areno URLs visible and the expected device status simulation display is not visible. Clearly, the device's http server allowed the login. Also, shortly after the login credentials were submitted, a dialog appears that states "disconnected from the server... xlx-........."

For firefox (FF 6.02) on both WIn7PCs, I get the same behavior with one exception - the connection process does not proceed to the point of displayig the authentication page to the device's http UI.

Of note, I am able to browse, login to and manipulate all http UI pages in an ODM-built TWC cable modem.... using any platform and any of the three browsers.

Also, of note, I have configured the ESW540-8P to backup config file nightly and automatically. This automatic access (using credentials provided in the "credentials" tab of the device modal) works great... even though it does not look like its supported in the device compatibility list.

I suspect these are FF/IE browser config related issues with specific Kubrick (Java?) aches and pains.But I'm just guessing. Fortunately, I have Safari on all three devices, so its not a big deal. Ideallly, though, I'd prefer to manage using FF - my browser of choice for all other webby-things.

Any help appreciated.

Cheers,

Dave

P.S. - have I told you lately how "killer" this remote "Cisco OnPlus" service is? This is beautiful thing you have built.

Howdy Captain!

The ESW540 has been somewhat 'entertaining' with cross-launch. We are awaiting a potential MR later this fall that may be able to address some of these issues. In the meantime, I'll get the documentation updated to reflect the following details on ESW540 support.

1. Port 80 and 'Fix Headers' are the correct configuration items to set for cross-launch.

2. The Safari browser works fine, but you have to ignore the 'connection lost' pop-up. Everything will work fine.

3. Firefox has a special problem. When you first connect with firefox, you will get an error. It is different with different versions of firefox. If you copy the URL and open a new window, then paste in the URL in the new window, things will work (again, with the connection lost message to ignore).

4. IE tends to work just fine, without any issues. I only tested with IE8. There might be an issue with IE7.

These problems come from the fact that OnPlus wasn't around when the ESW was developed and switches don't generally get tested for being able to support being connected to through a firewall. New SMB devices are getting tested with OnPlus to avoid this type of issue in the future.

Specifically, there is some Web Management page behavior in the ESW that trys to be compatible with all of the web browsers and some of that breaks down when you launch from another page or through an indirect method.

Enjoy,

Robert

P.S. Glad you like it. Your praise seems oddly familiar though ;-)

Thanks, Robert!

Perfect answer. Hopefully the new 300 series small biz switches from Cisco are included in the new browser test scripts. The 300's seem to be seling well.
