Management Cloud-Based Management for Entire Network The cloud-hosted web interface and mobile app make it easy to manage networks with Instant On APs and Switches. Simple Local Web GUI Management For management of individual switches, the intuitive Web GUI makes management simple, even for non-technical users. Supports up to five (5) HTTP and HTTP Secure (HTTPS) sessions. Firmware Update Provides notification of the latest firmware with the ability to schedule update at a preferred time through Instant On mobile app and cloud-based web portal. Default DHCP Client Mode Allows the switch to be directly connected to a network, enabling plug-and-play operation. In the absence of a DHCP server on the network, the switch falls back to the static address 192.168.1.1. Port Mirroring Enables traffic on a port or VLAN to be simultaneously sent to a network analyzer for monitoring. Event Logging and Alerts Provides detailed information for problem identification and resolution. Account Management Allows administrators to add, modify, delete and transfer management accounts and passwords for secure access to Instant cloud management solution. Locator LED Allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches. Schedule Configuration Global Schedule feature can be applied to time-based ACLs, port or interface shutdown, or PoE power delivery; up to 3 schedules can be configured. PoE scheduling allows user to configure a specific day/time of the week (e.g. business hours) for Instant On switches to supply power to connected devices (e.g. surveillance cameras, access points etc.). Quality of Service (QoS) Traffic Prioritization Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification. IEEE 802.1p/Q VLAN Tagging Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q. Class of Service (CoS) Sets the IEEE 802.1p/DSCP priority to queue mapping (4 queues). Supports strict priority queuing (SP) or weighted round robin (WRR) queuing. SP and WRR queuing can be configured on individual switch ports. Advanced Classifier Based QoS Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information. Access Switching SFP/SFP+ Fiber Connectivity Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support. SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports.
