General limitations

Table 3 lists general EZSwitchSetup limitations, which apply to all browsers and switch platforms.

TABLE 3	EZSwitchSetup Switch Manager limitations
Problem Area		Details
HTTP timeout		Very often, you may see the following message when you try to get data from a switch or to
		send a request to the switch:
		Failed to get switch response. Please verify the status
		of your last operation and try again if necessary.
		This indicates that an HTTP request did not get a response. The request was sent to the
		switch, but the connection was down, probably caused by a temporary loss of the Web
		server on the switch. Due to the nature of an HTTP connection, Switch Manager will report
		this error after a 90-second default timeout.
		In this case, verify the status of your last request, using Telnet to check related status, or
		click the Refresh button in the Switch Manager to retrieve related data. If your request did
		not get through to the switch, resubmit it. Executing a refresh from Switch Manager
		retrieves a copy of switch data at that moment; the data you entered can be lost if it had
		not already been committed to the switch.
Loss of Connection		Occasionally, you may see the following message when you try to retrieve data from the
		switch or send a request to the switch:

Switch Status Checking

The switch is not currently accessible.

The dialog title may vary, because it indicates which module is having the problem.

This is caused by the loss of HTTP connection with the switch, due to a variety of possible problems. Switch Manager automatically tries to regain the connection. While Switch Manager is trying to regain the connection, check if your Ethernet connection is still functioning. If the problem is not with the Ethernet connection, wait for Switch Manager to recover the connection and display the following message:

You will have to resubmit your request after closing this message.

If the temporary switch connection loss is caused by switch hot code load, or other similar operation, the Switch Explorer you are currently running can be downloaded from a different firmware version than the new one. In this case the following message displays: Switch connection is restored. The firmware version you are running is not in sync with the version currently on switch. Close your browser and re-launch Webtools.

You must close Switch Manager and relaunch it to reopen the connection.
