GEL-2861 ???? ??: 1 28-port l2 managed gigabit switch, 4 x sfp the GEL-2861 is a l2 managed switches designed for the smb market. the switches can be deployed indifferent target network topologies, from small to large.as well as ipv4 and ipv6 features. the GEL-2861 includes the best green-saving technologies(ieee 802.3az and green-ethernet). using the energy efficient ethernet standard, the switch automatically decreases power usage when network traffic is low. key features - ieee 802.1d/w/s ?? ?? ????(stp) ? ?? ??? - ?? ?? ??????? ieee 802.3ad lacp - ?? 512?? ???? ???? ??? ?? ??(acl) ? ???? ???? ??? ??? ieee 802.1x ?? ??? ?? - ip multicast filtering through igmp snooping v1 / v2 / v3 - supports port-based vlan, ieee 802.1q vlan tagging - ipv6 ???? ???? ???? ??? - ieee 802.1p qos with 8 priority queues ???? 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 802.3z 1000base-x,gigabit ethernet ieee 802.1p quality of service (qos) ieee 802.1q virtual lans (vlans) ieee 802.1d mac bridges ieee 802.1d standard spanning tree protocol ieee 802.1s multiple spanning tree (mstp) ieee 802.1w rapid spanning tree protocol (rstp) ieee 802.3x flow control ieee 802.3ad link aggregation control protocol (lacp) ieee 802.3af power over ethernet (poe) ieee 802.3at power over ethernet plus (poe+) ieee 802.3az energy-efficient ethernet link layer discovery protocol (lldp) universal plug and play (upnp) memory: 32mb www.level1.com page 1 of 4
