Chapter 42 Product Specifications Table 125 Firmware Specifications FEATURE DESCRIPTION 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. IP Multicast STP (Spanning Tree Protocol) / RSTP (Rapid STP)/MSTP (Multiple Spanning Tree Protocol) 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. With IP multicast, the Switch delivers IP packets to a group of hosts on the network-not everybody. In addition, the Switch can send packets to Ethernet devices that are not VLAN-aware by untagging (removing the VLAN tags) IP multicast packets. (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. 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! 362 MES-3728 User's Guide
