    Note: Some parameter changes are activated when you execute Save, and it is therefore not necessary to reboot the switch after making these changes. But if an asterisk appears next to any menu item you reconfigure, it is necessary to reboot the switch to implement the change.

  • Page 47: Using Password Security

    Using Password Security There are two levels of console access: Manager and Operator. For security, you can set a password on each of these levels. Level Actions Permitted Manager: Access to all console interface areas. This is the default level. (That is, if a Manager password has not been set prior to starting the current console session, then anyone having access to the console can access any area of the console interface.)

  • Page 48

    If there is only a Manager password set (with no Operator password), and the Manager password is not entered correctly when the console session begins, the switch operates on the Operator level. If there are both a Manager password and an Operator password, but neither is entered correctly, access to the console will be denied.

  • Page 49

    Select Return to Main Menu to exit from the Set Password screen. After a password is set, if you use LOGOUT or reboot or reset the Switch 800T, you will be prompted to enter the password to start a new console session.

This enables speeds of up to 400 Mbit/s in a 100Base-T trunk. On the Switch 800T you can implement up to four port...

    Virtual LANs (VLANs) Virtual LANs (VLANs) The switch supports port-based virtual LANs (VLANs). A VLAN is a collection of ports that belong to a single broadcast domain. (That is, all ports carrying traffic for a particular subnet address would belong to the same VLAN.) This allows workgroups to be defined on the basis of their logical function instead of their physical location, and does not require recabling.

    The switch does not translate encapsulation types (such as 802.2 to SNAP in IPX). As a result, if a host client sends an NSQ request for a server, the switch will always send a proxy response containing the address of a server support- ing the same encapsulation type.
