Enhancements:

The AV UI provides the following enhancements:

• Added new profiles: Allen & Heath gigaACE/GX, Audio Genelec Smart IP, AVoIP Lightware AV network, Blustream Multicast, Unite Audio, and Poly StudioNet Modular Room Switch (GSM4210PD only).
• Added the Add-Ports-Untagged-To-Profile menu on the Network Profiles page: Use this menu to add ports to existing profiles by selecting the ports on the switch panel and selecting a profile from the menu.
• Added the configured system name to the switch model name on the Overview page and it displays above the switch image.

The firmware provides the following enhancements:

• Migrated the time protocol from SNTP to NTP.
• Supports IGMPv3 and MLDv2 querier
• Supports SNMP traps notification for dynamically learnt or aged out MAC addresses
• Increases the maximum number of supported DHCP server leases to 4000 clients
• Supports management ACLs on out-of-band port in inbound direction
• Supports the configuration of a loopback IP address as a PIM RP address
• Supports suppression of duplicate message logging
• Supports multi-factor authentication (MFA) for the local authentication method
• Upgrade of OpenSSH and OpenSSL to version 9.8P1 and 3.1.6 respectively

Bug Fixes:

• Fixes the issue where unknown multicast traffic reaches the CPU. [CE-6323]
• Fixes the issue where an old configuration file fails to load onto switch by using the http file transfer method in the main UI. [MS-4486]
• Fixes the issue where the IGMP querier election process considers only the last octet of the IP address. [CE-5851]
• Fixes the issue where the same IP address displays for all the devices in the LLDP Remote Device Inventory page in the main UI. [CE-6086]
• Fixes the issue where the boot code does not upgrade automatically when the downloaded firmware includes a more recent boot code. [MS-4256]
• Fixes the issue where the ‘clear config’ CLI command causes the switch to crash. [CE-5424]
• Fixes the issue where switch automatically restarts when an email alert is configured. [CE-5937]
• Fixes the issue where a M4250, M4300 or M4350 switch connects to a M4500 MLAG domain, the M4500 switch reboots, and the AutoLAG between the M4250, M4300 or M4350 and M4500 domain does not occur. [MS-4306]
• Fixes the issue where the switch crashes. [MS-3983]
• Fixes the issue where a link remains administratively down if the 1G and 10G ports of two switches are connected by AXC761 or AXC763 transceivers. [CE-5918]
• Fixes the issue where the switch hangs and becomes unresponsive. [CE-5686]

This AV UI addresses the following bugs:

• Fixes the issue where CPU usage is high when the management VLAN is not default VLAN 1. [CE-6205]
• Fixes the issue where setting an access port to VLAN 1 tags VLAN 1 on all manual trunks. [CE-6189]

Known Issues:

• VLAN is incorrectly assigned to connected Shure devices when "Shure Split Audio and Control Network" profile is applied. Work Around: Manually add MAC based vlans to switch by using cli command "vlan association mac <mac address> <vlan id>”
• Enabling the DHCP server fails if you manage the switch over a management VLAN port that is part of the BirdDog AV Network profile or the Crestron DigitalMedia AV Network profile.
  Workaround: Use the OOB port to manage the switch or configure the DHCP server with a non-management VLAN for the BirdDog AV Network profile or the Crestron DigitalMedia AV Network profile.
• In stacking units, the AV UI profiles that were created on master units cannot be synced to member units. The profile on member units becomes a data profile.
  Work Around: Create an AV UI profile separately on each stacking unit.
• When the Audio Video Bridging (AVB) profile is created along with the AVoIP Lightware AV network, Blustream Multicast, Video, Video with AES67 audio, Video with Dante audio, or Visionary AV Network AV Network profiles, the MTU size remains 9198 on the AutoLAG/AutoTrunk ports.
  Work Around: Manually change the MTU size to 1500 on AutoLAG/AutoTrunk ports.

This firmware contains the following known issues:

• Interface counter ‘InDropPkts’ might increase slowly. [MS-4677]
  Workaround: This is false, and you can ignore it.

Warnings:

Read and follow these warnings before updating your firmware:

• SNTP is deprecated from firmware version 13.0.5.10 onwards and NTP is introduced. Configure an NTP server in your network. Remove SNTP related settings from the configuration file on firmware version 13.0.4.x before you apply it to the switch running firmware version 13.0.5.x.

General Information:

• The boot code remains at the existing version 1.0.0.11 in this switch firmware.
• AppMgr is upgraded to version 1.0.1.27 in this switch firmware.
