Known Issues:

- For user passwords, line passwords and enable passwords, automatic configuration migration is supported to a more secure SHA512 in 12.0.17.6 or later releases if the passwords are encrypted in AES in 12.0.15.7 or prior releases.
- User, line and enable passwords are encrypted with MD5 (salted) in 12.0.15.7 or prior releases, they won’t be migrated into 12.0.17.6 or later releases, so you must reconfigure them.
- SNMPv3 MD5 and SHA-based passwords from 12.0.15.7 or prior releases won’t be migrated into 12.0.17.6 or later releases, so you must reconfigure them.
- A new UI page added in the previous 12.0.11.x release under Routing > Multicast > Mroute Static-Multicast Configuration doesn’t display automatically after upgrading the switch firmware from 12.0.9.x to 12.0.11.x or later releases.

About Switch Firmware:

Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.

Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.

Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.

It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.

That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.
