New Features
- STP (Spanning Tree Protocol) management:
- Configure and monitor Spanning Tree Protocol across managed switches to prevent network loops. Supports both RSTP, MSTP and RPVST modes with per-switch configuration, including bridge priority and default protocol timers (hello time, max age, forward delay).
- Fiber Link Health in the Physical Topology view:
- Real-time visibility into the health of fiber optic links from the Physical Topology page. View per-port fiber module diagnostics including temperature, voltage, transmit and RX optical power, loss-of-signal detection, TX fault status, supported bit rate, and compliance information to quickly identify degraded or failing fiber connections.
- Support for the following new AV Network Profiles:
- AJA Profile
- Biamp AVB + Dante Audio Profile
- BluOS Profile
- AUDAC Profile
- Audio Video SMPTE Profile
- Shure Converged Profile (on M4350)
- AVB Milan Profile
- Profile color palettes:
- Assign custom colors to AV Network Profiles using a new color palette picker. Profile colors are reflected in the Topology and Profile pages, making it easier to visually distinguish profiles when designing or auditing complex sites.
- Managed Devices backup enhancements:
- Schedule automatic configuration backups for ProAV switches and Pro Routers with flexible repeat patterns (Once, Daily, Weekly, Monthly, or Weekdays).
- Topology enhancements:
- Manual Trunk: Manually select the member ports of a LAG directly from the Topology page.
- Add Ports Untagged To Profile: Bulk-assign multiple switch ports to an AV Network Profile in untagged mode in a single action, simplifying port provisioning when expanding existing profiles.
Bug Fixes:
- Fixes DHCP scope change fails on first attempt with VLAN conflict (CE-7701)
- Fixes QSC plugin reports "Operation Timed out after 5000 milliseconds" error; issue does not occur when Engage is closed (CE-7405)
- Fixes Shure Split profile issue when applied from Engage (CE-7734)
Known Issues:
-
Virtual devices do not support MLAG or stacking.
- You cannot create device-specific local VLAN profiles directly on individual virtual devices.
- Virtual devices do not support management VLAN IP configuration. Default IP information might appear in certain management views.
- Offline provisioning auto-onboarding is supported only when VLAN 1 is used as the management VLAN.
- Topologies using only fanout or LAG connections might experience onboarding failures when converting virtual devices to physical devices.
- M4500 switches using VLAN1 might experience onboarding issues in certain scenarios.
- Editing Link Aggregation (LAG) settings from the virtual device configuration page (DevicesàConfigure) might cause unexpected link behavior.
- Link speed selection during virtual link configuration is for viewing and planning purposes only.
- Some LAG configurations might not automatically clear if a linked virtual device is removed from the site.
- Port panel display is wrong in Engage AVUI and Engage port selection
Workaround: Port assignment works despite UI display issue. - The group firmware upgrade might not initiate on every onboarded device.
Workaround: Attempt to upgrade again on the devices that were not initially updated. - In rare cases, an AP may remain in “Rebooting” state after onboarding.
Workaround: Remove and attempt to onboard the AP again. - M4300 devices go offline after removing DICENTIS Conference System profile on a site.
Workaround: Reconnect port cables. - M4500 devices in the Managed Devices table might occasionally display as misaligned.
- You cannot use the $ symbol as the first character in the name or password of a site.
- M4500 models do not support NTP/SNTP.
- You cannot change the management VLAN on M4500 models that use the Engage Controller.
Workaround: Use CLI commands to update the PVID on the M4500 models. - The auto-stacking function on the M4300 and M4350 switches does not support the M4300-96X model.
Workaround: Use CLI commands if an M4300-96X model must be a member of a stack. - You cannot display the EEPROM information for certain fiber modules.
Workaround: Use the switch CLI to display the EEPROM information. - Connection requests might be refused during the onboarding process of an M4500 switch.
Workaround: Try again until the connection request is successful. - The management VLAN ID is inconsistent for onboarded devices if a pre-existing management VLAN ID does not match with the current site settings.
Workaround: Ensure the management VLAN ID is the same across the entire site before you upgrade the firmware.
Minimum Engage Controller Agent Version Requirements:
- Upgrade the M4250, M4300, M4350, and M4500 switches to a firmware version with the Engage Controller agent 2.2.15.16 or later to ensure proper functionality of features in the Engage Controller version 2.5.1.7.
- Upgrade the Pro Router PR460X to firmware version 2.7.0.111 or later to ensure proper functionality of features in the Engage Controller version 2.5.1.7.
- Upgrade the WBE718 and WBE758 access points to firmware version 12.5.0.22 or later to ensure proper functionality of features in the Engage Controller version 2.5.1.7.
- Upgrade the WAX608Y access points to firmware version 12.8.0.7 or later to ensure proper functionality of features in the Engage Controller version 2.5.1.7.
