Page Monitoring The Switch Displays detailed statistical information for the selected port such as packet type and frame size counters. Provides full listing of all unicast addresses stored in the switch, as well as sort, search and clear functions.
Error statistics on the traffic passing through each port are displayed. This information can be used to identify potential problems with the switch such as a faulty port or unusually heavy loading. The values displayed have been accumulated since the last system reboot. Page 61 Par ameter Descr iption Drop Events The total number of events in which packets were dropped due to lack of resources.
Received Bytes Total number of bytes of data received on the network. This statistic can be used as a reasonable indication of Ethernet utilization. The MAC address of a node. The VLAN s associated with this address or port. The port whose address table includes this MAC address. Logging Off the System Use the Exit command under the Main Menu to exit the configuration program and terminate communications with the switch for the current session.
This setting allows anyone to use the console menus to modify any operational parameter. To protect the configuration of the switch from unauthorized modification, you should enable password protection to the console menus. Highlight the IP address field and enter the IP address.
Press [Enter]. The switch allows up to five destinations to be configured for these trap messages to be sent. The software storage sector in the flash memory of the switch is reprogrammable, allowing you to easily download software feature enhancements and problem fixes to the switch from a local or remote location.
To download switch software via the serial port, do the following: With the console port connected, reset the switch by powering the switch off and then on. Two or more physical paths between different segments can be created through the switch, with the Spanning Tree Protocol choosing a single path at any given time and disabling all others.
If the chosen path fails for any reason, a disabled alternative is activated, thereby maintaining the connection. Page Configuring Vlans During periods of congestion, Class of Service settings ensure that traffic which has been assigned high priority is forwarded through the switch ahead of normal priority traffic. Page Configuring Port Operation Configuring Port Operation You can configure switch ports for operational parameters such as auto- negotiation, duplex mode, port speed and flow control.
The Base-FX fiber ports always operate in full duplex mode and Mbps speed. Therefore, these two parameters, along with auto-negotiation, are not configurable on these fiber ports. When this option is enabled, the switch tries to obtain an IP address from the BootP server. Each trunk can combine up to four ports into an aggregate connection with up to Mbps of bandwidth when operating at full duplex.
Page Snmp Management Managed entities supporting SNMP typically contain software, which runs locally on the device and is referred to as an agent. Page Appendix A. Additionally, if the connection between B and C goes down, the link between A and C becomes active, establishing a path between B and C through switch A. You can cause serious network performance degradation if you do not fully understand Spanning Tree concepts. Be sure to consult personnel experienced with this process prior to configuring Spanning Tree parameter s.
Page Spanning Tree Protocol Operation Spanning Tree Protocol Operation When the Spanning Tree Protocol is enabled for the first time or when there is a change in the network topology, such as a failure or the addition or removal of a component, the Spanning Tree Protocol automatically sets up the active topology of the current network.
Page Appendix B. Therefore, all frames are transferred internally through the switch with a VLAN tag. This tag may already be on the frame entering the switch, or added to the frame by the switch. VLAN information already existing on frames entering the switch is automatically handled by the switch.
When this switch receives these messages, it will automatically place the receiving port in the specified VLANs, and then forward the message to all other ports. Page Appendix C. Page 96 Figure C-1 shows priority queuing operating within a switch. Frames entering the switch through ports 1 and 4 are tagged as normal traffic and placed in a normal priority queue on the outbound port.
Frames entering through ports 2 and 5 are tagged as high priority traffic and placed in a high priority queue on the outbound port. Page Appendix D. Table A These ports are wired MDI-X.
All undefined pins are not used. The power cord set appliance coupler, flexible cord, and wall plug you received with the switch meets the requirements for use in the country where you purchased the switch. Page Country-Specific Requirements Country-Specific Requirements Table A-3 lists the power cord set requirements by country and identifies the accredited agency within that country. Page 50 Japanese Dentori Law.
Page Appendix B. Flow Control Workstation A to stop sending packets by inducing collisions on port X. For the full duplex pause frame mechanism to work, the device connected to the switch port must also support IEEE Page Appendix C.
