Forty-eight 10/100/1000 switched RJ-45 ports with automatic medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection
4 mini Gigabit Interface Converter (mini-GBIC) ports for fiber or copper interconnections
Nonblocking, store-and-forward switching mechanism
Simplified quality of service (QoS) management enabled by advanced queuing techniques using 802.1p, differentiated services (DiffServ), or type of service (ToS) traffic prioritization specifications
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 (Link Layer Discovery Protocol [LLDP])
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
Broadcast, multicast, and unknown unicast storm control
Port mirroring for noninvasive monitoring of switch traffic
Jumbo frame support (10 KB)
Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support
Fully rack mountable using the included rack-mounting hardware
