Systems use the Simple Network Management Protocol (SNMP), an industry-standard
protocol, to exchange management information between network devices. SNMP
enables administrators to remotely monitor network/application performance,
find and solve network problems, and plan for network growth.
network contains: managed devices, agents, and Network Management Stations
(NMS). Management Information Bases (MIBs) are used to structure the
information that is passed between the components in the system.
A managed device
designates a network node that contains an SNMP agent and resides on a managed
network. Managed devices collect and store management information and make it
available by using SNMP.
Unified ICM/CCE components are valid managed devices:
Administration & Data Server
An agent resides
on a managed device. An agent (or one of its subagents) retrieves local
management information and translates it into the SNMP format to forward it to
an SNMP Management Station. Subagents collect information for various
components and then forwards that information to a master agent.
Management Station (NMS) comprises an SNMP management application together with
the computer on which it runs. An NMS executes applications that monitor and
control managed devices. An NMS provides the bulk of the processing and memory
resources that are required for network management. Cisco Unified ICM/CCE SNMP
works with SNMP standards-compliant NMSs.
Information Base (MIB) designates a collection of information that is organized
hierarchically. You can access instrumentation defined by a MIB using the SNMP
protocol. MIBs are composed of managed objects, which are identified by object
A managed object
(sometimes called a MIB object or an object) possesses one of any number of
specific characteristics of a managed device. Managed objects comprise one or
more object instances, which are essentially variables.
ICM/CCE supports the following MIBs:
CISCO-CDP-MIB (Cisco Discovery Protocol)
- (System-Level Managed Objects for Applications)
The Cisco Contact Center Application (CISCO-CONTACT-CENTER-APPS) MIB
contains tables of objects and their corresponding values for the major
components of an Unified ICM/CCE Enterprise/Hosted Edition installation.
Router (and a table of NICs)
Peripheral Gateway (PG) (and a table of PIMs)
Distributor Administration and Data Server
CTI Gateway (CG)
CTI OS Server
The MIB definition can be viewed by opening the file:
in a text editor or a MIB browser.
The MIB also provides a notification object which defines the format
of SNMP notifications generated by Unified ICM/CCE components. The SNMP
subagent on the Unified ICM/CCE Logger component sends alarms to the NMS.
The Cisco Discovery Protocol MIB (CISCO-CDP-MIB) provides information
about device identifications, CDP running status, CDP transmitting frequency,
and the time for the receiving device to hold CDP messages (time to live). For
more information, see
"Cisco Discovery Protocol Support."
The Host Resources MIB found in Cisco SNMP is an implementation of the
Host Resources MIB document, proposed standard
1514. It is also compliant with Host Resources MIB, draft standard
RFC 2790. This
MIB defines objects that are useful for managing host systems and allows SNMP
access to useful host information, such as the storage resources, process
table, device information, and the installed software base.
System-level Managed Objects for Applications MIB
The System-level Managed Objects for Applications (SYSAPPL) MIB,
RFC 2287, supports configuration, fault detection,
performance monitoring, and control of application software. It provides for
tables that define an application as a series of processes and services. This
includes objects for applications installed on the system, elements and
processes that are included in an application, and current and previously run
