After you select a language, this menu is displayed only if you press Esc from the Main Menu.

  • Page 61: System Information

    System Information The System Information screen displays the current parameter settings for the switch. All of the screens associated with system information are read only. To change any parameter or setting you must go through the System Configuration menu. The System Information screen provides three paths to switch statistics and status information.
  • Page 62 This field allows you to define how many seconds elapse between hello time messages that are sent from this switch to all other switches, if the Spanning Tree Protocol has defined this switch as the root switch. This field is configurable in the range of 1 to 65535 seconds with a default of 2 seconds.
  • Page 63 Provides the time since the last topology change was detected by the bridge entity. • Root Cost Provides the path cost from the switch to the designated root bridge. • Hold Time Specifies the time value that determines the interval length during which no more than two configuration bridge PDUs shall be transmitted by this node.
  • Page 64 This information provides the path cost to the designated root bridge. The valid range for this value is from 1 to 65,535. Entering a value of 0 causes the switch software to compute the value automatically. The default value for this field is 0.
  • Page 65 • Rx CRC Error Frame This counter increments whenever a frame is received on a particular interface that is an integral number of octets in length but does not pass the frame check sequence (FCS). • Rx Frame Too Long This counter increments whenever a frame is received on this port that is greater than 1,518 octets in length.

  • Page 70: Snmp Configuration

    SNMP Configuration The SNMP Configuration menu displays a list of the parameters that allow you to set and change values, parameters, and addresses within an SNMP management environment. To change any setting, type in the corresponding number. The screen is refreshed, and the command line displays the current parameter value for the selected parameter and allows you to enter new data.

  • Page 71: Reset To Default

    • Management using SNMP Configuration Examples The BayStack 303 and 304 switches are well suited for the initial migration from shared 10BASE-T segments to dedicated bandwidth for switch connections between segments, end-stations, 100BASE-T Fast Ethernet servers, and fiber or copper Fast Ethernet backbone connections. The switches also function well as segment or desktop switches.
  • Page 72 BayStack 304 switch as a segment switch Figure 3-3 illustrates how a BayStack 304 switch can be used as a segment switch to alleviate server and network center contention and to provide better ratio connections to 10 Mb/s users. This configuration also offers an additional eight dedicated 10 Mb/s connections for users.

  • Page 73: Spanning Tree Protocol

    The BayStack 303 switch can be used as a desktop switch to provide 100 Mb/s connections to the server and network center and to give dedicated 10 Mb/s connections to up to 23 users instead of shared 10 Mb/s connections (see Figure 3-4).

  • Page 74: Managing The Baystack Switches

    Managing the BayStack Switches You can manage your BayStack 303 and 304 switches in any of the following three ways: • In-band signaling using SNMP (see page •...
  • Page 75 Access to the switch through SNMP is controlled by community names. The community names set for the switch must match those used by the SNMP management station for successful communication to occur. The switch uses two community names.

  • Page 85: Addresses

    Remember that the BayStack switches each have a MAC station address and an IP address. The MAC station addresses are unique because each address contains the Bay Networks manufacturer ID and node ID codes. The switch is shipped with a default IP address of 000.000.000.000.

  • Page 86: Link Status

    The 100 Mb/s ports are designed to operate using Category 5 UTP cabling only. Category 5 UTP cable is a 2-pair cable certified to handle up to 100 MHz bandwidth. To minimize crosstalk noise, maintain the twist ratio of the cable up to the point of termination (untwist at any termination should not exceed 0.5 inches).
