SNMP Basics

Network Management 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.

An SNMP-managed 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.
    The following Unified ICM/CCE components are valid managed devices:
    • Routers
    • Loggers
    • Peripheral Gateways (PGs)
    • Administration & Data Server
    • CTI Gateways (CGs)
    • CTI OS Servers
    • Outbound Option
  • 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.
    Unified ICM/CCE supports the following agents:
    • SNMP Master Agent
    • Unified ICM/CCE Application (CISCO-CONTACT-CENTER-APPS-MIB) Subagent
    • Platform Subagent(s)1
    • System Applications Instrumentation (SYSAPPL-MIB) Subagent
    • Host Resources (HOST-RESOURCES-MIB) Subagent
    • Cisco Discovery Protocol (CISCO-CDP-MIB) Subagent2
  • A Network 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.
  • A Management 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 identifiers. 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.
    Cisco Unified ICM/CCE supports the following MIBs:
    • CISCO-CONTACT-CENTER-APPS-MIB
    • CISCO-CDP-MIB (Cisco Discovery Protocol)
    • HOST-RESOURCES-MIB
    • SYSAPPL-MIB - (System-Level Managed Objects for Applications)

SNMP Management Information Bases

Cisco Contact Center Application MIB

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.

Components include:

  • Router (and a table of NICs)
  • Logger
  • Peripheral Gateway (PG) (and a table of PIMs)
  • Distributor Administration and Data Server
  • CTI Gateway (CG)
  • CTI OS Server
  • Outbound Option

The MIB definition can be viewed by opening the file: <INSTALL_DRIVE>\icm\snmp\CISCO-CONTACT-CENTER-APPS-MIB.my 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-CONTACT-CENTER-APPS-MIB is available at: ftp:/​/​ftp.cisco.com/​pub/​mibs/​v2/​CISCO-CONTACT-CENTER-APPS-MIB.my.

Cisco Discovery Protocol MIB

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 Cisco CDP MIB is available at ftp:/​/​ftp.cisco.com/​pub/​mibs/​v2/​CISCO-CDP-MIB.my.

Host Resources MIB

The Host Resources MIB found in Cisco SNMP is an implementation of the Host Resources MIB document, proposed standard RFC 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 applications.
