28-port Gigabit PoE Managed Switch CISCO SG300-28PP (SG300-28PP-K9-EU)
- 24 ports 10/100/1000 Gigabit RJ-45 with auto medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection
- 2 Combo Gigabit mini-GBIC ports and 802.3at PoE+, Maximum power of 30W to any Gigabit Ethernet base port. Total power 180W.
- Simplified QoS management enabled by advanced queuing techniques using 802.1p, differentiated services (DiffServ), or type of service (ToS). prioritisation schemes enhances the performance of real-time applications such as voice and video.
- Configuration and monitoring from a standard web browser with WebView management.
- Secure remote management of the switch via Secure Shell (SSH) and SSL secure channel network protocols.
- 802.1Q-based VLANs enable segmentation of networks for improved performance and security.
- Private VLAN Edge (PVE) for simplified network isolation of guest connections or autonomous networks.
- Automatic configuration of VLANs across multiple switches through Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP).
- Automatic port configuration through auto MDI/MDIX and 802.1ab with Link Layer Discovery Protocol (LLDP) and Plug and Play support.
- User/network port-level security via 802.1X authentication and MAC-based filtering.
- Increased bandwidth (up to 8x) and added link redundancy with Link Aggregation Control Protocol (LACP).
- Enhanced rate-limiting capabilities provide control, including back pressure to control the rate at which data can flow into and out of a port
- Multicasting, broadcasting, and flooding control.
- Port mirroring for non-invasive monitoring of switch traffic.
- Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support.
- No blocking, store-and-forward switching mechanism.
- Fully rack mountable using the included rack-mounting hardware.
