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
