3. EL –G4E24M FIBER OPTIC UNMANAGED SWICTH SPECIFICATIONS Broadcast control - The broadcast storm is constrained. When the threshold value for controlling the broadcast storm is reached, the broadcast packets are stopped from being forwarded. Multicast control - IGMP Snooping of multicast packets, IGMP v1/v2/v3 Interface binding - Each port binding group contains up to 8 ports, and 6 port binding groups are supported meanwhile. - Supporting dynamic LACP or static aggregation. Port mirroring - Supporting flow-based mirroring and the or port. Cascading - Stacking 32 switches. - Adopting the cluster technology; managing uniquely through a unique IP address; saving address resources. Security features - IEEE 802.1x port authentication. - Port security. - Hardware supporting IP ACL, MAC ACL and Vlan ACL. - Hardware supporting dhcp snooping. - Hardware supporting DAI and static/dynamic ARP prevention. - Supporting user authentication through Web page. - Supporting remote RADIUS and “TACACS + authentication” - Supporting hierarchical user management and password protection. Service quality - Head Of Line (HOL) mechanism. - Four transmission queues on each port are mapped to eight. priority values of 802.1p. - WRED, WFQ, SP and FIFO. - Best-effort service / Differentiated service. - Strict priority / Weighted round robin. - First come first served. - TOS re-labeling / RTS. Network management - SNMP v1/v2, RMON (groups 1, 2, 3, 9), Telnet, CLI page, WEB page - Supporting the general NMS software, Broad Drictor - Supporting NTP - Supporting SSH / Supporting PDP (compatible with Cisco CDP) Tel : 031- 257- 7157 Fax : 031- 257 - 7159 e-mail:h0824@elimopt.co.kr 경기도 수원시 권선구 산업로 155 번길 50, 엘림빌딩 A 동 3 층 ( 고색동, 산업 3 단지 ) http:/www.elimopt.co.kr
