Appendix A Product Specifications Table 101 Feature Descriptions (continued) FEATURE DESCRIPTION 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 tell the Switch how to forward IP traffic when you configure the TCP/IP parameters manually. 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 STP) Loop Guard IP Source Guard Link Aggregation Port Authentication and Security Authentication, Authorization and Accounting Device Management Port Cloning Syslog Firmware Upgrade This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management. (R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a Switch to interact with other (R)STP-compliant switches in your network to ensure that only one path exists between any two stations on the network. The Switch also allows you to set up multiple STP configurations (or trees). Ports can then be assigned to the trees. Use the loop guard feature to protect against network loops on the edge of your network. Use IP source guard to filter unauthorized 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. The Switch supports authentication, authorization and accounting services via RADIUS and TACACS+ AAA servers. Use the web configurator or commands to easily configure the rich range of features on the Switch. Use the port cloning feature to copy the settings you configure on one port to another port or ports. The Switch can generate syslog messages and send it to a syslog server. Download new firmware (when available) from the ZyXEL web site and use the web configurator, CLI or an FTP/TFTP tool to put it on the Switch. Note: Only upload firmware for your specific model! 282 ES-2024 Series User's Guide
