LOCAL MANAGEMENT

This chapter explains how to set up a management terminal to access the SEHI Local Management. It also explains how to use the Local Management screens and commands.

Local Management supplies the tools to manage the SEHI and all of its attached segments. It allows the user to perform the following tasks:

Assign an IP address and subnet mask

Select a default gateway

Control access to the SEHI through the community names established in the Community Name Table

Designate which Network Management Workstations receive trap messages from the device

Navigate through the Management Information Base (MIB) and manage the objects within it from a remote location. Given the appropriate security level, the MIB is accessible from the SEHI through SNMP Tools.

Local Management also allows the user to manage each non-intelligent stackable hub attached to the SEHI, and provides a Statistics screen to view error, collision, and traffic statistics for the entire stack, individual module, or individual port.
