    AC Power Receptacle The AC power receptacle accepts the AC power cord (supplied). For installation outside of North America, make sure that you have the proper power cord for your region. Any cord used must have a CEE-22 standard V female connector on one end and must meet the IEC 320-030 specifications.

  • Page 40: Virtual Local Area Networks (vlans)

    BayStack 410-24T switches support up to 64 port-based or protocol-based VLANs. When a switch port is configured to be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains.

  • Page 41: Security

    Security Your BayStack 410-24T switch security feature can provide two levels of security for your local area network (LAN): • RADIUS-based security -- Limits administrative access to the switch through user authentication. • MAC address-based security -- Limits access to the switch based on allowed source MAC addresses.

  • Page 42

    -- MAC address-based security is used to allow up to 448 authorized stations (MAC addresses) access to one or more switch ports (see “MAC Address-Based -- The switch is located in a locked closet, accessible only by authorized Technical Services personnel. • Student dormitory Dormitory rooms are typically occupied by two students and have been prewired with two RJ-45 jacks.

    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.

  • Page 44: Ieee 802.1p, Igmp Snooping Feature, Configuration And Switch Management

    The MAC address-based security feature is based on Nortel Networks BaySecure ™ Ethernet networks from unauthorized surveillance and intrusion. To learn more about the Nortel Networks BaySecure LAN Access for Ethernet, refer to the Bay Networks Guide to Implementing BaySecure LAN Access for Ethernet (Part number 345-1106A). IEEE 802.1p The BayStack 410-24T switch can prioritize the order in which packets are forwarded, on a per-port basis.

  • Page 45: Flash Memory Storage, Switch Software Image, Configuration Parameters

    Switch Software Image Your switch’s software image is stored in flash memory. The flash memory allows you to update your switch software image with a newer version, without changing the switch hardware (see “Software Download” on page 3-102). An in-band connection between the switch and the TFTP load host is required to download the software image.

  • Page 47: Ieee 802.1q Vlans, Port Mirroring

    BayStack 410-24T switches support up to 64 port-based VLANs with IEEE 802.1Q tagging available per port. When a switch port is configured to be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains.

  • Page 48: Bootp Automatic Ip Configuration/mac Address

    IP address, subnet mask, IP address of the default router (default gateway), and software image file name. When the switch is participating in a stack configuration, a Stack MAC address is automatically assigned during the stack initialization. The base unit’s MAC address, with a software offset, is used for the Stack MAC address.

  • Page 49: Snmp Mib Support, Snmp Trap Support

    SNMP MIB Support The BayStack 410-24T switch supports an SNMP agent with industry standard MIBs, as well as private MIB extensions, which ensures compatibility with existing network management tools. The BayStack 410-24T switch supports the MIB-II (RFC 1213), the Bridge MIB (RFC 1493), and the RMON MIB (RFC 1757), which provide access to detailed management statistics.

    You can use BayStack 410-24T 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 that is connected to the switch, or by creating a virtual LAN (VLAN) through the switch.

    VLANs Spanning Multiple Switches You can use VLANs to segment a network within a switch. When connecting 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.

For this configuration to work properly, spanning tree participation must be set to Disabled because the STP is not supported across multiple LANs.

    This appendix describes the BayStack 410-24T switch port connectors and pin assignments. RJ-45 (10BASE-T/100BASE-TX) Port Connectors The RJ-45 port connectors stations without using crossover cables. (See page D-2 for information about MDI-X ports.) For 10BASE-T connections, use Category 3 (or higher) UTP cable. When using 10BASE-T/100BASE-TX MDAs, use only Category 5 UTP cable.

    Table D-1 lists the RJ-45 (8-pin modular) port connector pin assignments. Table D-1. MDI and MDI-X Devices Media dependent interface (MDI) is the IEEE standard for the interface to unshielded twisted pair (UTP) cable. For two devices to communicate, the transmitter of one device must connect to the receiver of the other device.
