  • Page 3: Introduction

    The NP2624M switch provides a convenient way to operate layer 2 management through a web browser. The User-friendly drop-down menus allow the user to easily learn, control and monitor the Switch.

  • Page 4: Unpacking

    1.1 Unpacking Open the shipping carton of the Switch and carefully unpack its contents, the carton should contain the following items: • One NP2624M port Fast Ethernet Layer 2 Switch. • One Mounting Kit including 2 mounting brackets and screws.

  • Page 5: Installation

    Rack Installation: The NP2624M switch can be mounted in an ELA standard-sized, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the switch side panels (one on each side) and secure them with the screws provided.

    PC to the switch through an RS232 cable. The other method is in-band-management, where you also connect your PC to the switch, but do so through an Ethernet network either locally or remotely, or simply directly connect your PC and the switch with an Ethernet cable. Before you activate the management function in the Switch, you should read the instructions below carefully to ensure you can access the switch through your PC.
  • Page 7 1.3.2 In-band Management through Ethernet In addition to terminal mode operation, the NP2624M switch also supports in-band management through a web browser. This function is much more user-friendly than terminal mode and can be performed either locally or remotely through Ethernet.

  • Page 8: Telnet Management

    1.3.3 Telnet management In addition to local terminal mode operation, the NP2624M switch supports remote management through Telnet over a network or the internet without a web browser. In this mode, the user has to enter the same settings as required in in-band management to the IP Configuration before executing the Telnet program.

  • Page 9: Led Indicators Information

    1.4 LED indicators information There are many LEDs on the front panel of switch. After the initial power on, these LEDs will reflect the current status within the switch as explained below: There is one power LED on the left side of the front panel. When power is applied, it turns green.

  • Page 26: Filter Database

    2.5.6 Filter Database 2.5.6.1. IGMP Snooping The NP2624M switch supports multicast IP. IGMP protocol can be enabled on this web page, and IGMP snooping information is displayed on this page. All multicast groups, VIDs and member ports are displayed in the list. IP multicast addresses range from 224.0.0.0 through 239.255.255.255.
  • Page 27 2.5.6.2. Static MAC Address When you add a static MAC address, it remains in the switch’s address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device’s MAC address when the disconnected or powered-off device is active on the network again.

  • Page 28: Mac Filtering

    1. In the MAC Address box, enter the MAC address that you want to filter. 2. If tag-based (802.1Q) VLAN are set up on the switch, in the VLAN ID box, type the VID to associate with the MAC address.

    Layer 2 switch. However, all the network devices are still plugged into the same switch physically. The NP2624M switch supports port-based, 802.1Q (tagged-based) and protocol-base VLAN in web management page. In the default configuration, VLAN support is disabled.
  • Page 30 VLAN ID based not only on the default PVID but also other information about the packet, such as the protocol. The NP2624M switch will support protocol-based VLAN classification by means of built-in knowledge of layer 2 packet formats used by selected popular protocols, such as Novell IPX and AppleTalk’s Ether Talk, and some degree of programmable protocol matching capability.

  • Page 32 In this page, the user can create a Tag-based VLAN. 256 VLAN groups can be configured. If 802.1Q VLAN is enabled, then all ports on the switch will belong to the default VLAN (VID is 1). The default VLAN cannot be deleted.
  • Page 33 There are two possible strategies of the 802.1v support: Port- based VLAN and Port-and-Protocol-based VLAN. Both are supported in the NP2624M. Users set the VID to mark the packet from the untagged port and then the packet can be scheduled by the way of the IEEE 802.1q.

    IP (real IP or private IP). By this utility, an administrator can manage many more network devices and reduce the demand of real IPs, because every real IP switch can be an agent host for any network devices in their private IP domain.
  • Page 113 Reduce the demand of real IP (public IP). Since there are up to 32 devices which have a IP agent as “Single IP” switch, meaning that the switch becomes a network agent and handles all functions of these devices, MIS can reduce the number of hosts that are directly connected to internet, and make use of real IPs more efficiently.
