# ECS205L/ECS208L ## v1.1.1 ### \[Issue Fixed] * Fixed an issue where the device could fail to obtain an IP address via DHCP after changing the management interface VLAN, resulting in network disconnection. * For security concerns, TLS 1.0 and TLS 1.1 have been removed. All EXT-related secure communications now support only TLS 1.2, including HTTPS web access, EnGenius Cloud connectivity, and firmware downloads. ## v1.1.0 ### \[New Features] * Supports **VLAN Trunking** to bypass the 16-VLAN configuration limit, enabling traffic transmission for additional VLANs. * Supports **IGMP Querier** to efficiently manage multicast traffic by maintaining group memberships and preventing flooding in networks without a Layer 3 router. * Supports **Port Isolation** to enhance traffic security by strictly preventing communication between isolated port groups. * Be able to be managed by **EnGenius Private Cloud** (EPC). * Supports **Configuration Rollback** function, allowing the device to automatically rollback to the last stable configuration if a misconfiguration causes a loss of Cloud connection. ## v1.0.3 * First release. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
