gsw-4876 version: 3 50-port web smart gigabit ethernet switch, 2 x sfp the levelone gsw-4876 is an intelligent 50 ports gigabit web smart switch, provides 48 x 1000base-t ports and 2 x gigabit sfp (small form factor pluggable) slots. the switch supports a flexible web-based management interface, snmp for both ipv4 and ipv6 as well as layer 2 management features. despite its affordable pricing, the gsw-4876 is equipped with many advanced features such as internet group management protocol (igmp) snooping v1/v2/v3 forwarding, vlans, spanning tree, link aggregation control protocol (lacp), qos with 8 priority queues, upnp for auto-discovery and configure devices, storm control for protects against broadcast/multicast/unknown unicast and else more. the gsw-4876 offers a complete web management solution for small-to-median businesses. key features - supports port-based vlan, ieee 802.1q vlan tagging - 48 gigabit ethernet ports and 2 gigabit sfp slots - mld, telnet, snmp v1, v2c & v3, rmon, web browser, and tftp management - ip multicast filtering through igmp snooping v1 / v2 / v3 - - ieee 802.1d/w/s spanning tree protocol (stp) and port mirroring - supports access control list (acl) authentication of up to 512 entries and port-based security with ieee802.1x - supports ipv4/ipv6 network operation - ieee 802.1p qos with 8 priority queues - ieee 802.3ad lacp for auto port aggregation - supports universal plug and play (upnp) for auto-configure network devices - supports simple network time protocol (sntp) time server - 10k jumbo frames to increase data transfer rates www.level1.com page 1 of 5
highlight cost-effective solutions for ipv6 deployment featuring the most comprehensive set of ipv6 migration technologies, including stateless auto configuration which simplifies ip address assignment by creating a plug-and-play environment in the absence of a dhcp server and the implementation of dual ip stack that allows not only for running both ipv4 and ipv6 applications in parallel but also for facilitating gradual transition between these applications. related product gvt-0302 1.25g smf sfp transceiver, 80 km, 1550nm specifications system specifications standards & protocols: ieee 802.3 10-base-t, ethernet ieee 802.3u 100-base-tx, fast ethernet ieee 802.3ab 1000base-t, gigabit ethernet ieee 802.1p quality of service (qos) ieee 802.1x port-based network access control (pnac) ieee 802.1q virtual lans (vlans) ieee 802.1d mac bridges ieee 802.1d standard spanning tree protocol (stp) ieee 802.1w rapid spanning tree protocol (rstp) ieee 802.1s multiple spanning tree (mstp) ieee 802.3ad link aggregation control protocol (lacp) ieee 802.1ab link layer discovery protocol (lldp) ieee 802.3x flow control (full-duplex flow control) universal plug and play (upnp) memory: 16mb buffer memory: 512kb connectors and cabling: 48 x rj-45 10/100/1000base-t ports 2 x 100/1000base-x sfp slots (shared) indicator: power, link/port activity transmission method: store-and-forward power: power consumption: 50 watts for system power voltage: 100-240v ac, 50-60 hz, 2a, internal power supply features general: quality of service (qos) 8 hardware queues per port traffic classification based on ieee 802.1p cos, dscp, supports wrr, strict scheduling, or hybrid mode rate limiting - ingress: resolution 16 kbps - egress: resolution 16 kbps www.level1.com page 2 of 5
