Table 2 describes the backoff delay times for each retry:

Table 2 Retry and Backoff Time

Retry

Backoff Delay

 

 

Initial Attempt

N/A

First

8 seconds

Second

16 seconds

Third

32 seconds

Fourth

1 minute

Fifth

1 minute

Final

1 minute

 

 

Once the Server Load Balancer and Server Load Balancer Plus have backed off the timeout, it will never go back down again. For example, if a packet is dropped it may go from a time out of 8 to 16 seconds and remains at a 16 second timeout as long as packets continue to be received. The retry count resets to indicate an initial attempt. The upgrade terminates on its own, in the worse case 6 minutes if no TFTP server is responding.

If an upgrade is initiated and then subsequently canceled, you must wait at least 1 minute before initiating a subsequent upgrade.

Disable Attack Filters To ensure that the software upgrade sequence completes successfully, all Attack Filters should be disabled for the duration of the upgrade. The Attack Filters should be re-enabled once the upgrade completes.

Restart the Browser The browser must be restarted after an upgrade is performed.
