ABOUT THE SWITCH
minimizes the total number of VLANs required. Private VLANs and normal VLANs can exist simultaneously in the same switch.
Multicast Switching
Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping.
Traffic Priority
This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using four distinct categories with Weighted Round Robin queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data.
Description of Hardware
RJ-45 Ports
The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All of these ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See “10BASE-T/100BASE-TX Pin Assignments” on page -2.)
Each of these ports support IEEE 802.3x auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically, if this feature is also supported by the attached device. If a device connected to one of these ports does not support auto-negotiation, the correct speed will be sensed by the port, but the transmission mode will default to half duplex.
