6.1.1 Ethernet Management Interface Protocols
For SNMP, Telnet, or HTTP operation, the CPA must be configured with the
Ethernet control option. From the front panel, select CONFIG: REMOTE 
ETHERNET. See Chapter 5. FRONT PANEL OPERATION for further information.
The user PC provides access to Ethernet-based remote Monitor and Control (M&C) of the CPA
through three separately operated protocols:
• Simple Network Management Protocol (SNMP). This requires a user-supplied Network
Management System (NMS) and a user-supplied Management Information Base (MIB) File
Browser.
• ISSPA Telnet Interface. This requires use of a user-supplied terminal emulation program
such as HyperTerminal.
• ISSPA Web Server (HTTP) Interface. This requires a compatible user-supplied web
browser such as Internet Explorer.
6.2 SNMP Interface
The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for
managing devices on IP networks. An SNMP-managed network consists of three key
components:
• The managed device. This includes the CPA.
• The SNMP Agent. This is the software that runs on the CPA. The ISSPA SNMP Agent
supports both SNMPv1 and SNMPv2c.
• The user-supplied Network Management System (NMS). This is the software that runs
on the manager.
6.2.1 Management Information Base (MIB) Files
MIB files are used for SNMP remote management of a unique device. A MIB file consists of a
tree of nodes called Object Identifiers (OIDs). Each OID provides remote management of a
particular function. Compile these MIB files in a user-supplied MIB Browser or SNMP Network
Monitoring System server.
