    Gigabit Interface Converter (GBIC) Gigabit Interface Converters (GBICs) are hot-swappable input/output enhancement components designed for use with Nortel Networks products to allow Gigabit Ethernet ports to link with fiber optic networks. Port connectors The BayStack 420 Switch uses 10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.

    Although Ethernet switches and bridges divide a network into smaller collision domains, they do not affect the broadcast domain. In simple terms, a virtual local area network provides a mechanism to fine-tune broadcast domains. Your BayStack 420 Switch allows you to create port-based VLANs: • IEEE 802.1Q port-based VLANs A port-based VLAN is a VLAN in which the ports are explicitly configured to be in the VLAN.

  • Page 37: Radius-Based Network Security

    Create a list of up to 448 MAC addresses and specify which addresses are authorized to connect to your switch or stack configuration. The 448 MAC addresses can be configured within a single standalone switch, or they can be distributed in any order among the units in a single stack configuration.

    The response can be to send a trap, turn on destination address (DA) filtering, disable the specific port, or any combination of these three options. The MAC address-based security feature is based on Nortel Networks BaySecure LAN Access for Ethernet, a real-time security system that safeguards Ethernet networks from unauthorized surveillance and intrusion.

  • Page 41: Snmp Mib Support

    SNMP MIB support The BayStack 420 Switch supports an SNMP agent with industry standard MIBs, as well as private MIB extensions, which ensures compatibility with existing network management tools. The switch supports the MIB-II (RFC 1213), Bridge MIB (RFC 1493), and the RMON MIB (RFC 1757), which provide access to detailed management statistics.

    BootP automatic IP configuration/MAC address The BayStack 420 Switch has a unique 48-bit hardware address, or MAC address, that is printed on a label on the back panel. You use this MAC address when you configure the network BootP server to recognize the BayStack 420 Switch BootP requests.

  • Page 43: Configuration And Switch Management

    The BayStack 420 Switch is shipped directly from the factory ready to operate in any 10BASE-T or 100BASE-TX standard network. You must assign an IP address to the switch or stack, depending on the mode of operation. You can set both addresses by using the console port or BootP, which resides on the switch.
  • Page 44 Chapter 1 BayStack 420 Switch Optivity network management software consists of views, most of which are maps that illustrate the interconnections between the segments, rings, and nodes of your network. The views allow you to analyze network performance and fault conditions on the individual segments and specific areas in your network.

    Use BayStack 420 switches to connect workstations, personal computers (PCs), and servers to each other by connecting these devices directly to the switch, through a shared media hub connected to the switch or by creating a virtual LAN (VLAN) through the switch.

  • Page 46: Segment Switch Application

    Segment switch application Figure 7 shows a BayStack 420 Switch used as a segment switch to alleviate user contention for bandwidth and eliminate server and network bottlenecks. Before segmentation, 88 users had a total bandwidth of only 10 Mb/s available. After segmentation, 92 users have 40 Mb/s, four times the previous bandwidth, while adding 22 dedicated 100 Mb/s connections.

    The base unit is the unique stack unit that you configure with the Unit Select switch on the front panel. One BayStack 420 Switch in the stack must be configured as the base unit; all other units in the stack must have their Unit Select switch set to Off (see BayStack 420 Switch as the base unit.

  • Page 60: Vlans Spanning Multiple Switches

    Chapter 2 Network configuration VLANs spanning multiple switches You can use VLANs to segment a network within a switch. When you connect multiple switches, it is possible to connect users of one VLAN with users of that same VLAN in another switch. However, the configuration guidelines depend on whether both switches support 802.1Q tagging.

  • Page 61: Vlans Spanning Multiple Untagged Switches

    Figure 18 shows VLANs spanning multiple untagged switches. In this configuration, Switch S2 does not support 802.1Q tagging and you must use a single switch port on each switch for each VLAN. For this configuration to work properly, you must set spanning tree participation to Disabled (the STP is not supported across multiple LANs).
