    Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time. In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow’s rapidly improving switching and routing...

  • Page 11: Features

    For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205 meter network diameter limit for 100BASE-TX networks.

  • Page 25: Switch Management

    Out-of-Band Management for the Switch is accomplished through a locally connected management terminal to the RS-232 console port. Through this port, a user can set up, monitor, or change the configuration of the Switch. The Spanning Tree Algorithm (STA) provides the capability for the Switch to operate properly with other Bridges in a SNMP network supporting the STA.

    Switch IP Address to meet the specification of your networking address scheme. In addition, you can also set in the Switch an IP Address for a gateway or a router. It is useful when the network management station is not located on the same network as the Switch, making it necessary for the Switch to go through a gateway or router to reach the network manager.

  • Page 27: Traps

    Gigabit Ethernet Switch User’s Guide For security, you can set in the Switch a list of IP Addresses of the network managers that you allow to manage the Switch. You can also change the default Community Name in the Switch and set access rights of these Community Names.

    ♦ New Root This trap indicates that the Switch has become the new root of the Spanning Tree, the trap is sent by a bridge soon after its election as the new root. This implies that upon expiration of the Topology Change Timer the new root trap is sent out immediately after the Switch’s selection...

    Switch, a diskette listing the Switch’s propriety enterprise MIBs can be obtained by request. If your software provides functions to browse or modify MIBs, you can also get the MIB values and change them (if the MIBs’ attributes permit the write operation).

  • Page 30: Aging Time

    Entries, which make up the auto-learned-node address, are aged out of the address table according to the Aging Time that you set. The Aging Time can be from 1 to 99 minutes. A very long Aging Time can result with the out-of-date Dynamic Entries that may cause incorrect packet filtering/forwarding decisions.

  • Page 31: Spanning Tree Algorithm

    STA Operation Levels STA operates on two levels: the bridge level and the port level. On the bridge level, STA calculates the Bridge Identifier for each Switch, then sets the Root Bridge and the Designated Bridges. On the port level, STA sets the Root Port and Designated Ports.
  • Page 32 ♦ Bridge Identifier This is the combination of the Bridge Priority (a parameter that you can set) and the MAC address of the switch. Example: 4 00 80 C8 00 01 00, where 4 is the Bridge Priority. A lower Bridge Identifier results in a higher priority for the switch, and thus increases it probably of being selected as the Root Bridge.

    ♦ Bridge Max. Age The Max. Age can be from 6 to 40 seconds. At the end of the Max. Age, if a BPDU has still not been received from the Root Bridge, your Switch will start sending its own BPDU to all other Switches for permission to become the Root Bridge.

  • Page 35 Gigabit Ethernet Switch User’s Guide STA setup can be somewhat complex. Therefore, you are advised to keep the default factory settings and STA will automatically assign root bridges/ports and block loop connections. However, if you need to customize the STA parameters, refer to Table 5-1.

  • Page 37: Using The Console Interface

    NTERFACE Your Gigabit Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP TELNET protocol. You can use this facility to perform many basic network management functions.

  • Page 38: Console Usage Conventions

    ♦ One stop bit You can also access the same functions over a TELNET interface. Once you have set an IP address for your Switch, you can use a TELNET program (in a VT-100 compatible terminal mode) to access and control the Switch. All of the screens are for the most part identical, whether accessed from the console port or from a TELNET interface.
