Enhancements:

A generic QoS setting is applied in the AV UI for all profiles, allowing improvement of the quality of PTP, audio, and video streams.

Bug Fixes:

Fixes the issue where a PTP clock synchronization problem occurs when you create AVB and other AV profiles on the same uplink port.
Fixes the issue where an AVB audio problem occurs when the switch receives multiple broadcast packets.
Fixes the issue where audio distortion occurs when ARP packets are processed in queue 5.
Fixes the issue where IGMP does not recognize the multicast group with IP address 239.0.0.5.
Fixes the issue where the PoE port status is unexpectedly changed to 802.3af when the OID fastpathpowerEthernet is set through SNMP.
Fixes the issue where a configuration conflict occurs when both an ACL and a DiffServ policy are configured on a port.
Fixes the issue where 802.1x authentication fails after you change the port mode from ‘auto’ to ‘force-authorize.’
Fixes the issue where a DHCP IP address is not (or incorrectly) assigned after the client restarts the DHCP process and switch has multiple DHCP requests in its processing queue.
Fixes the issue where the link status remains up after you bring down the VLAN 1 interface, that is, the VLAN interface is administratively down.
Fixes the issue where a problem occurs with the order of the source IP address in an LLDP packet. The correct order is first the network port (IP management interface), then the service port (OOB port), and finally the LAN routing interface.
Fixes the issue where a fixed speed and duplex value are displayed for the routing interface.
Fixes the issue where multiple crashes occur when all ports are configured as multicast router ports, and you create an empty profile with the Auto-Trunk feature enabled.
Fixes the issue where the fan runs at high speed after you reset model M4250-10G2XF-PoE++ (SKU number GSM4212UX) to factory defaults from the CLI, which you access from the AV UI.

Warning:

For user passwords, line passwords, and enable passwords that are encrypted with AES in firmware release 13.0.2.24 or earlier releases, automatic migration is supported to the more secure SHA512 in release 13.0.2.31 or later releases.
User passwords, line passwords, and enable passwords that are encrypted with MD5 (salted) in firmware release 13.0.2.24 or earlier releases are not migrated to release 13.0.2.31 or later releases, so they must be set manually.
SNMPv3 MD5 and SHA-based passwords from firmware release 13.0.2.24 or earlier releases are not migrated to release 13.0.2.31 or later releases, so they must be set manually.

Know Issues:

If you upgrade from firmware release 13.0.0.x to release 13.0.2.x, you might encounter JavaScript errors in the main UI.
