Installing and Setting Up the Unit Grounding Reliable grounding of this equipment must be maintained. Particular attention should be given to electrical connections when connecting to a power strip, rather than direct connections to the electrical outlet. Connecting Ethernet Devices For optimum performance, the Ethernet segments connected to the NH2025-10 must be configured carefully.
Getting Started This section describes how to connect to the management port, log into the Command Line Interface, and set the unit’s IP Address. Connecting to the Management Port With the product we supply a management cable. You can use it to get access to the management port. To configure the serial ports do the following items: 1. Connect the cable provided to the management port and communication interface (COM1 or COM2) of your PC. 2.
Getting Started NOTE: If the switch has no IP Address, then the provided IP Configuration changes the running parameters as well as the NVRAM-based database. If the switch was already configured, the command only changes the NVRAM database. Therefore, to use the new parameters you should reset the Switch, using the warm-reset command. You can also use the set-ip command to accomplish this. When you do, the mask and broadcast are automatically set to defaults according to the IP address class.
Using the Command Line Interface This section describes how to use the Command Line Interface (CLI) to configure and manage the NH2025-10 switch. Command Conventions The following conventions are used within this guide to make understanding and using the CLI easier. Command Items appearing in this typeface are to be typed as shown. Italics Italicized items are variables and represent values. For example, represents an IP address in dotted decimal notation as 123.1.2.3.
Using the Command Line Interface Example SYS_console> ping 129.1.1.7 ? The unit displays the next level of parameters: ping IP traffic generator [arg #0] destination IP address [arg #1] number of packets to send or 0 for endless ping SYS_console> ping 129.1.1.7 Getting Command Group Help To find out the command groups that are available within the unit, enter a question mark at the CLI prompt.

Configuring, Modifying, and Monitoring the Unit Setting the flow control Ports are compliant to flow control specifications 802.3x or back-pressure. You can set a port to perform flow control only if this port is in full duplex mode otherwise backpressure is applied to control the incoming flow of data. When the port is configured to do 802.3z flow control the switching engine sends a continuous flow of idle frames to avoid dead locks.
Configuring, Modifying, and Monitoring the Unit EtherChannel The EtherChannel feature is also known under the name of Port Trunking. It allows equipment to pass data through multiple physical links. Providing an extended bandwidth and redundancy. NOTE: If you want to use this feature in conjunction with VLAN be aware that you must set exactly the same VLAN configuration for each physical link that belongs to the EtherChannel group.
Configuring, Modifying, and Monitoring the Unit Example SYS_telnet>new-ec run 23-24 RUN:OK Ethernet Channel Table from RUN database =========================================== Ether-Channel-ID Ports =========================================== 1 23 24 Deleting the EtherChannel Configuration del-ec The del-ec command deletes the trunk port configuration.

Configuring, Modifying, and Monitoring the Unit Spanning Tree Protocol (STP) The switch software supports IEEE 802.1D Spanning Tree Protocol (STP) which ensures the existence of a loop-free topology in networks that contain any arrangement of devices. STP produces a logical tree topology to ensure that a single path exists between any two end stations on an interconnected network. STP also provides a high degree of fault tolerance.
Configuring, Modifying, and Monitoring the Unit Spanning Tree Parameters Normally, each switch or bridge in a network participates in STP. The units work together as peers to determine which links are to forward packets between LANs, and which links are to be blocked. Links that forward packets are chosen based on which link has the lowest pathcost and priority.
Configuring, Modifying, and Monitoring the Unit Topology Change Notification BPDU A non-Root interface sends a Topology Change Notification BPDU (TCN BPDU) over its Root interface any time it believes that the network topology has changed. The following circumstances can cause this to happen: • A Root interface gives up its Root status and the topology state is changing. • A switch receives a TCN BPDU from another unit via a non-Root interface.
Configuring, Modifying, and Monitoring the Unit Viewing Bridge Parameters get-st-bcfg For determining Root in a spanning tree network, the MAC address is a tie breaker when priority values for devices are equal. In this case, the unit with the lowest MAC address becomes the root. For NH 2025-10 products, the lowest numbered switch has the lowest MAC address. Example SYS_console>get-st-bcfg 802.
Configuring, Modifying, and Monitoring the Unit Hello Time: set-br-hellot The set-br-hellot command sets the Spanning Tree bridge’s hello time. set-br-hellot The hello_time is an integer in the range 1..10, displayed in seconds. The default value is 2. Forward delay: set-br-fwdel The set-br-fwdel command sets the Spanning Tree Bridge Forward Delay, which controls the amount of time between the listening and forwarding states of a port.
Configuring, Modifying, and Monitoring the Unit Example set-prt-prio 4 128 Priority was changed for port 4 SYS_console> Enabling/disabling a port: set-prt-enb To enable or disable spanning tree on a port. The default value is disabled.
Configuring, Modifying, and Monitoring the Unit Switching Commands This section contains instructions for managing the Switching Database with the Command Line Interface. To view the available switch commands, enter switch-db at the CLI prompt. The Switching Database consists of 12K entries.

Configuring, Modifying, and Monitoring the Unit Important Considerations Before configuring your VLAN you must strictly follow the scenario: 1. Set the VLAN mode to tagged. 2. Set the server ports (see Server Port chapter in this manual). 3. Set the tagging ports (see ISVLAN chapter in this manual). 4. Configure the new VLAN. 5. Configure the management VLAN. Virtual LANs can be used to limit the broadcast domain and to establish secure virtual workgroups.
Configuring, Modifying, and Monitoring the Unit Inter-Switch VLAN or ISVLAN The inter-switch VLAN conforms to the standard IEEE 802.1q, which describe the method of passing tagged frames through a physical link. To satisfy the need, the frame format should be changed and 4 more bytes are added to the frame header between the end of address field and the frame type. Tag Field Format This is a 4 bytes long field divided into two sub-fields of 2 bytes respectively named TPID and TCI.
Configuring, Modifying, and Monitoring the Unit Setting a Tagged Port set-tag-outbound-mode The set-tag-outbound-mode command can be used to enable or disable VLAN tagging to port/s on a network on which all nodes support the IEEE 802.1Q standard or a comparably capable network. Do not enable a port connected to a network on which there are any nodes that do not support the IEEE 802.1q standard.
Configuring, Modifying, and Monitoring the Unit NOTE: You must issue the new-srvr-port command before the new-vlan commands for those VLANs to which it will be made available. new-srvr-port Set a Vlan Server port(s) [arg #0] database type - either {run|nvram|all} [arg #1] server ports - ports list in format: d1-...-dn [arg #2] VLAN Tag { 2..4095 } opt.[arg #3] VLAN priority 1..8 (1..4 - low, 5..
