DEVICE MANAGEMENT

This chapter explains the applications enabling administrative and management functions in the 7600 Card.

The following topics are discussed:

QThe user interfaces and protocols used

QManagement types and connection

QManagement within the 7600 Card

User Interfaces and The following applications provide user interfaces to the 7600 Card:

Protocols

Q7600 Card administration console - Local Management (LM).

QExternal SNMP-based network management applications, such as Transcend Manager.

The 7600 Card uses virtual terminal protocols, such as rlogin and Telnet in addition to the LM to run the system administration console and SNMP to run the SNMP-based management applications (refer to Figure 14-1).
