The management capabilities of the SPS switches include support for DHCP option 82, allowing for assignment of IP
addresses to subscribers based on where they connect to the network. Management can be performed through a
GUI or command-line interface (CLI). The switches also support SNMP for management from a network
management station.
Features
●
Twenty-four 10/100/1000 switched RJ-45 ports that deliver up to 2000 Mbps of throughput per port
●
Two shared mini Gigabit Interface Converter (mini-GBIC) slots for fiber and copper Gigabit Ethernet
expansion
●
48-Gbps nonblocking, store-and-forward switching mechanism
●
Simplified QoS management enabled by advanced queuing techniques using 802.1p, Differentiated Services
(DiffServ), or type of service (ToS) traffic prioritization
●
Configuration and monitoring from a console port with the CLI or from a standard web browser with WebView
management
●
Secure remote management of the switch via SSH and SSL secure channel network protocols
●
802.1Q-based VLANs, enabling segmentation of networks for improved performance and security
●
Stacking Q-in-Q VLANs, allowing customer VLANs to transparently cross a service provider network and
isolate traffic among customers
●
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 medium dependent interface (MDI) and MDI crossover (MDI-X) detection
