                        1. MANAGEMENT OVERVIEW Configuration Options For advanced management capability, the Enterasys Networks’ Vertical  Horizon VH-8G provides a menu-driven system configuration program.  This program can be accessed by a direct connection to the serial port on  the switch’s rear panel (out-of-band), or by a Telnet connection over the  network (in-band). The switch’s management is based on SNMP (Simple Network  Management Protocol). SNMP permits a switch to be managed from any  PC in the network usin

                        In-Band Connections Prior to accessing the switch via a network connection, you must first  configure it with a valid IP address, subnet mask, and default gateway  using an out-of-band connection or the BootP protocol. Telnet Connection Prior to accessing the switch via an in-band Telnet connection, you must  first configure it with a valid IP address, subnet mask, and default gateway  using an out-of-band connection or BootP protocol. After configuring the  switch’s IP parameters, you can acces

                        2. VH-8G USER INTERFACE Overview Access is gained to the console menus by directly connecting a terminal  to the console port with a null-modem cable connection, or using Telnet  to access the switch over the network. These menus allow you to  reconfigure the switch, as well as to monitor the status and performance  of the switch. The menus have a layout similar to the sample Main Menu  shown in Figure 2-1. The information is divided into the following parts:  Menu Name (includes access privile

                        User Access Once a direct connection to the console port or a Telnet connection is  established, the login screen for the on-board configuration program  appears. You may need to press Enter a few times to display the screen. The default user names are “admin” and “guest,” with no passwords. The  administrator has Read/Write access, which allows you to read and  modify switch information. The guest has Read Only access to the  management program, which allows you to view switch information, but
