Chapter 41 Product Specifications Table 124 Firmware Specifications FEATURE DESCRIPTION Classifier and Policy You can create a policy to define actions to be performed on a traffic flow grouped by a classifier according to specific criteria such as the IP address, port number or protocol type, etc. Queuing Queuing is used to help solve performance degradation when there is network congestion. The following scheduling services are supported: Strict Priority Queuing (SPQ) Weighted Round Robin (WRR), and Weighted Fair Queuing (WFQ). This allows the Switch to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth. Bandwidth Control Bandwidth control means defining a maximum allowable bandwidth for incoming and/or out-going traffic flows on a port. Broadcast Storm Control Broadcast storm control limits the number of broadcast, multicast and destination lookup failure (DLF) packets the Switch receives per second on the ports. Port Mirroring Port mirroring allows you to copy traffic going from one or all ports to another or all ports in order that you can examine the traffic from the mirror port (the port you copy the traffic to) without interference. Static Route Static routes allow the Switch to communicate with management stations not reachable via the default gateway. Multicast VLAN Registration (MVR) Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand (MoD)) using multicast traffic across a network. MVR allows one single multicast VLAN to be shared among different subscriber VLANs on the network. STP (Spanning Tree Protocol) / RSTP (Rapid STP)/MSTP (Multiple Spanning Tree Protocol) Loop Guard IP Source Guard Link Aggregation Port Authentication and Security This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management. (M)(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a Switch to interact with other (M)(R)STP-compliant switches in your network to ensure that only one path exists between any two stations on the network. Use the loop guard feature to protect against network loops on the edge of your network. Use IP source guard to filter unauthorized DHCP and ARP packets in your network. Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link. For security, the Switch allows authentication using IEEE 802.1x with an external RADIUS server and port security that allows only packets with dynamically learned MAC addresses and/or configured static MAC addresses to pass through a port on the Switch.
