1-2 Switch Description

The AT-9724TS has 24 1000T Gigabit ports that may be used in uplinking various network devices to the Switch, including PCs, hubs and other switches to provide a gigabit Ethernet uplink in full-duplex mode.

In addition, the AT-9724TS is equipped with 4 SFP (Small Form Factor Portable) combo ports, which are to be used with fibre-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances.These 4 SFP ports support full-duplex transmissions, have auto- negotiation and can be used with AT-MG8LX10 (1000LX),AT-MG8SX (1000SX) and AT-MG8ZX (1000ZX) transceivers.These four ports are referred to as “combo” ports which means that both the SFP ports and the 1000T ports are numbered the same (21–24) and cannot be used simultaneously.Attempting to use the ports simultaneously will cause a link down status for the 1000T ports. SFP ports will always have priority over these 1000T ports.

Also included at the rear of the Switch are two 10-gigabit stacking ports used to stack up to twelve switches in a ring topology.The AT-9724TS may be used as the master unit of a switch stack when utilizing these ports and, in total, may provide a stacking solution of up to 288 gigabit ports.

Note: The four SFP combo ports on the Switch, numbered 21–24 cannot be used simultaneously with the corresponding 1000T ports, numbered 21–24. If both ports are in use at the same time (ex. port 21 of the SFP and port 21 of the 1000T), the SFP ports will take priority over the combo ports and render the 1000T ports inoperable.

•IEEE 802.1x Port-based and MAC-based Access Control

•IEEE 802.1Q VLAN

•IEEE 802.1D Spanning Tree, IEEE 802.1W Rapid Spanning Tree and IEEE 802.1s Multiple Spanning Tree support

•Stacking support in Ring topology

•Access Control List (ACL) support

•IP Multinetting support

•Protocol VLAN support

•Single IP Management support

•Access Authentication Control utilizing TACACS, XTACACS,TACACS+ and RADIUS protocols

•Dual Image Firmware

•Simple Network Time Protocol support

•MAC Notification support

•System and Port Utilization support

•System Log Support

•High performance switching engine performs forwarding and filtering at full wire speed up to 128Gbps.

•Full- and half-duplex for all gigabit ports. Full duplex allows the switch port to simultaneously transmit and receive data. It only works with connections to full-duplex-capable end stations and switches. Connections to a hub must take place at half-duplex.

•Support broadcast storm filtering

•Non-blocking store and forward switching scheme capability to support rate adaptation and protocol conversion

•Supports by-port Egress/Ingress rate control

•Efficient self-learning and address recognition mechanism enables forwarding rate at wire speed

•Support port-based enable and disable

•Address table: Supports up to 8K MAC addresses per device

•Supports a packet buffer of up to 3 Mbits

•Supports Port-based VLAN Groups

•Port Trunking with flexible load distribution and fail-over function

•IGMP Snooping support

•Layer 3 support including DVMRP, OSPF and RIP
