1. MANAGEMENT OVERVIEW Configuration Options For advanced management capability, the VH-SMGMT Vertical Horizon Management Module provides a menu-driven system configuration program. This program can be accessed by a direct or modem connection to the serial port on the Management Module (out-of-band), or by a Telnet connection over the network (in-band). The Management Module is based on SNMP (Simple Network Management Protocol). This SNMP agent permits a switch stack to be managed from any

When attaching to a PC, set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 19200 bps (for initial configuration). Also be sure to set flow control to “none.” (Refer to “Configuring the Serial Port” on page 19 for a complete description of configuration options.)

2. VH-2402S USER INTERFACE Overview Access is gained to the console menus by connecting a terminal to the console port (with a direct cable connection or over modems), or using Telnet to access the Management Module over the network. These menus allow you to reconfigure the switch, as well as to monitor the status and performance of the switch or the attached stack. The menus have a layout similar to the sample Main Menu shown in Figure 2-1. The information is divided into the following pa
