Known Issues:
This AV UI contains the following known
issues:
·
Affected Profile: Audio Dante - Potential
Network Loop on Dual-Port Dante Devices
If
a Dante device with two Ethernet ports has both ports connected to the network
simultaneously, a Layer 2 loop may occur, causing network instability or
outage.
Workaround: Choose
one of the following:
Connect only one
Ethernet port per Dante device — leave the secondary/redundant port
disconnected.
Manually re-enable STP
on the affected interface
Connect the Dante Primary
and Secondary ports to two separate, independent networks with
different VLANs, in line with Audinate’s official
redundant design.
As an alternative, use
Video with Audio Dante profile and toggle on PTP-TC.
This firmware contains the following known issues:
- M4500 does
not support RPVSTP for the DICENTIS Conference system profile—connect
Bosch devices to other switch models and uses M4500 as a core switch only.
- The M4500
is offline and inaccessible after you change the management VLAN in the
Engage Controller.
Workaround: Do not change the management VLAN when the M4500 is on
site or manually add the VLAN to the interface using the CLI. See the
below example:
(Switch) (Interface) # switchport allowed vlan
add X
(Switch) (Interface) # switchport native vlan X
General Information:
- AppMgr is upgraded to version 1.0.5.27 in this
switch firmware.
- If the
encrypted password in the configuration file does not adhere to the
NETGEAR password policy, when the configuration file is loaded on the
firmware version 7.0.4.26 or later, you must create a new password during
the initial login.
