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.

 

 

Switch Name Change

If you change the switch name using EZSwitchSetup or SNMP and then open a Telnet

 

 

window to verify the name change, the CLI prompt (for example, switch:admin>) displays

the previous name. The Telnet prompt cannot pick up the new switch name until the switch is rebooted.

Workaround: To display the correct switch name in the CLI prompt after a switch name update using EZSwitchSetup or SNMP, fastboot the switch.
