SNMP
SNMP, or Simple Network Management Protocol, is a command/response protocol
used for managing IP devices on a network.
An SNMP Manager such as HP OpenView© is used to issue requests for status,
performance, and configuration information to an IP device on the network.
An SNMP compliant IP device responds to commands issued by the SNMP
Manager. The code that responds to the SNMP request is known as an SNMP Agent.
Depending on the source and access privileges of the request, the Agent may or may
not issue the requested information. Access levels range from:
■
No Access - the SNMP Manager does not have access privileges.
■
Read-only - the SNMP Manager can read the information only, but cannot modify it.
■
Read/Write - the SNMP Manager can read and edit the information.
SNMP is an open standard and the capabilities are defined in specifications known
as RFCs. The 833IS supports the following RFCs:
■
RFC 1157 - A Simple Network Management Protocol. (SNMP)
■
RFC 1213 - Management Information Base for Network Management of TCP/IP
Internets: MIB II.
■
RFC 1471 - The Definitions of Managed Objects for the Link Control Protocol of
Point-to-Point Protocol.
■
RFC 1573 - Evolution of the Interface Groups of MIB-II.
■
RFC 1643 - Definitions of Managed Objects for Ethernet-like Interface Types.
■
RFC 1659 - Definitions of Managed Objects for RS-232-like Hardware Devices
using SMIv2.
■
RFC 1696 - Modem Management Information Base (MIB) using SMIv2.
■
RFC 1742 - AppleTalk Management Information Base II.
■
RFC 1743 - IEEE 802.5 MIB using SMIv2.
■
RFC 2127 - ISDN Management Information Base using SMIv2.
The 833IS Agent supports read access of the SNMP information only. Configuration and
control is performed via the 833IS Manager.
The 833IS can be controlled by an SNMP Manager that has dialed in to the 833IS.
