New Features and Enhancements
Improved login times in CLI startup on Nodegrid Manager (NGM) when running with over 5000 managed devices.
Fixed SNMPv3 username validation, on the NETWORK::SNMP page, so error messages are now displayed in the correct field.
Fixed Issues
Added proper timeouts to Network Failover tracking on the TRACKING::NETWORK::FAILOVER page, so it no longer hangs indefinitely if the failover service or its database becomes unresponsive.
Fixed IPSec tunnel status and controls for non‑admin users with system permissions, on the NETWORK::VPN(IPSEC)::TUNNEL page, so tunnel state and actions now appear accurately according to their access level.
Fixed a problem where USB ports on NetSR systems with multiple USB cards could be enumerated incorrectly, ensuring consistent port mapping after reboots.
Fixed a TACACS+ login issue that could cause authentication to fail or show error messages when using specific Tacquito server setups
Fixed an issue, on the SYSTEM::CENTRAL MANAGEMENT::VARIABLES page, where using certain characters in a variable field could break the page and prevent further access.
Improved startup handling of virtual network bridges so customer VMs reliably regain connectivity after device reboots or power outages.
Resolved a storage‑related issue, on the ACCESS::TABLE page, when launching KVM HTML5 sessions that could fill an internal partition.
Restored SNMP support for NSR switch expansion cards so monitoring tools can again read their status using the expected OIDs.
Updated our routing stack so BGP over BFD sessions remain stable after device reboots, eliminating the need for manual session resets.
