Chapter 4: Advanced Topics The CheetahSwitch Workgroup-3514F/26F/26G supports Layer 2 switching and other advanced features, which are described in this chapter. Layer-2 Switching When a frame enters a port, its destination MAC address is checked in the address database to see which port leads to this destination. If the destination address belongs to the incoming port, the frame is dropped or “filtered”... -
Page 100: Virtual Lans
Advanced Topics Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that the link to the Root Bridge is down. -
Page 101: Assigning Ports To Vlans
Virtual LANs This switch supports the following VLAN features: • Up to 255 VLANs based on the IEEE 802.1Q standard • Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol • Port overlapping, allowing a port to participate in multiple VLANs •... -
Page 102: Forwarding Traffic With Unknown Vlan Tags
Advanced Topics GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests. Forwarding Traffic with Unknown VLAN Tags This switch only supports 255 VLANs, but up to 4094 VLANs are supported by the IEEE 802.1Q VLAN protocol. Therefore, if this switch is attached to endstations that issue VLAN registration requests, it will have to forward unknown VLAN tags. -
Page 103: Multicast Filtering
Multicast Filtering Multicast Filtering Multicasting sends data to a group of nodes instead of a single destination. The simplest way to implement multicasting is to broadcast data to all nodes on the network. However, such an approach wastes a lot of bandwidth if the target group is small compared to overall the broadcast domain. -

Priority assignment to a packet in the CheetahSwitch Workgroup-3514F/26F/26G can be accomplished in any of the following ways: • Priority can be explicitly assigned by end stations which have applications that require a higher priority than best-effort. -
Page 105: Remote Monitoring
Remote Monitoring Remote Monitoring Remote Monitoring (RMON) provides a cost-effective way to monitor large networks by placing embedded or external probes on distributed network equipment (hubs, switches or routers). Accton’s AccView network management software can access the probes embedded in recent Accton network products to perform traffic analysis, troubleshoot network problems, evaluate historical trends, or implement proactive management policies. - Page 106 Advanced Topics...

Page 108: Upgrading Firmware Via The Serial Port
Troubleshooting Upgrading Firmware via the Serial Port You can upgrade system firmware by connecting your computer to the serial port on the switch, and using a console interface package that supports the XModem protocol. (See “Required Connections” on page 1-1.) 1. - Page 109 Upgrading Firmware via the Serial Port 3. After the file has been downloaded, the console screen will display information similar to that shown below. Press “s” to start the management interface, change the baud rate back to 19200, and press Enter. The Logon screen will then appear.

Appendix B: Pin Assignments Console Port Pin Assignments The DB-9 serial port on the switch’s rear panel is used to connect to the switch for out-of-band console configuration. The on-board menu-driven configuration program can be accessed from a terminal, a PC running a terminal emulation program, or from a remote location via a modem connection. -
