랜공사 [Cisco [SRW2024] [SG300-28] 26-Port 10/100/1000 Gigabit Switch + 2 Shared Mini-GBIC / SFP port L3 Static Routing , IPV6 지원]

• 24 high-speed ports optimized for the network core or to support bandwidth-intensive applications

• Enhanced QoS helps ensure a consistent network experience and supports networked applications including voice, video, and data storage

• Strong security protects network traffic to keep unauthorized users off the network

• Twenty-four 10/100/1000 switched RJ-45 ports with auto medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection

• 2 mini Gigabit Interface Converter (mini-GBIC) slots for fiber and copper Gigabit Ethernet expansion (shared)

• Simplified QoS management enabled by advanced queuing techniques using 802.1p, differentiated services (DiffServ), or type of service (ToS) prioritization 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 Universal Plug and Play (UPnP) 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

• Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support
