About Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) isan industry-standard interface for exchanging
management information between network devices. SNMP and its components provide you with
information about your Cisco CRS system. You can refer to this information to monitor and manage the
status of the Cisco CRS system, its subsystems, and its related installed components. You can also use
this information to troubleshoot problems, if they arise.
You can set up SNMP traps to automatically notify you of high-severity messages and errors that are
generated by the Cisco CRS system.
SNMP Basics
A network management system (NMS) uses SNMP to exchange management information between
devices on a network. An SNMP-managed network is made up of the following main components:
• Managed devices—Network nodes, each containing an SNMP agent. Managed devices collect and
store information and make this information available using SNMP.
• Agents—Network management software that resides on a managed device. An agent contains local
knowledge of management information and translates the information into a form that is compatible
with SNMP.
