Known Issues:
- In stacking units, an AV UI profile that is created on the primary management unit does not synchronize to member units. The profile on member units becomes a data profile.
Workaround: Create an AV UI profile separately on each stacking unit.
- When you select ports for the Harman Professional AV Network profile, the “Harman Device” option assigns all ports to the control VLAN instead of dynamically detecting the Harman devices.
Workaround: Select the audio option if the connected Harman devices are audio devices; Select the video option if the connected Harman devices are video devices.
- For the ETC Lighting profile, the profile logo is not displayed for the device MAC OUI detection. All other profile functions are working as expected.
- In the AV UI, you cannot configure the Fanout setting for a standby member of a stack of M4300-96X switches.
Workaround: Use the main UI to configure the Fanout setting.
- When you configure the Force Multicast or Block Multicast settings for a LAG in the AV UI, the configuration is successfully applied to the switch, but the Force or Block icons do not display on the LAG port.
- When you configure the Force Multicast or Block Multicast settings on one or several ports of a M4300-96X switch in the AV UI, the port status information (such as VLAN profiles, colors, and so on) no longer displays.
Workaround: Refresh the AV UI page.
This firmware contains the following known issues:
- After you upgrade the firmware from 12.0.9.x to 12.0.11.x or a newer release, when you use the main UI and you select Routing > Multicast > Mroute Static-Multicast Configuration, the page does not display automatically.
Workaround: After the firmware upgrade, clear your browser cache.
Warnings:
Read and follow these warnings before updating your firmware:
- For user passwords, line passwords, and enable passwords that are encrypted with AES in firmware release 12.0.15.7 or earlier releases, automatic migration is supported to the more secure SHA512 in release 12.0.17.6 or later releases.
- User passwords, line passwords, and enable passwords that are encrypted with MD5 (salted) in firmware release 12.0.15.7 or earlier releases are not migrated to release 12.0.17.6 or later releases, so they must be set manually.
- SNMPv3 MD5 and SHA-based passwords from firmware release 12.0.15.7 or earlier releases are not migrated to release 12.0.17.6 or later releases, so they must be set manually.
