Thanks! I just hoping there will be patch for ZD1100, as the latest FW is version 9.10.2.0.130.
Another thing, we still have ZF7363 in operations which make it difficult to upgrade to FW 10 that has the patch. Finger crossed.....
Just FYI, as informed by syamantak_omer, I could upgrade the ZD even if I don't have support entitlement. Just download the img file, then upgrade. Mine automatically given 30 days Support after the upgrade.
Or contact Support where they'll give grac...
