Configuring Embedded Resource Manager (ERM)-MIB

---

First Published: February 19, 2007

Last Updated: February 27, 2008

The Embedded Resource Manager (ERM)-MIB feature introduces MIB support for the Embedded Resource Manager (ERM) feature. The ERM feature tracks resource usage information for every registered resource owner and resource user. ERM ensures efficient usage of available resources. The ERM-MIB feature allows you to monitor the usage of resources by gathering resource usage information using MIB objects. The network manager can use the information collected by the ERM-MIB objects to ensure the optimal use of the resources.

Prerequisites for ERM-MIB

Simple Network Management Protocol (SNMP) must be enabled on the router before notifications (traps) can be configured or before SNMP GET operations can be performed.

Information About ERM-MIB

The ERM-MIB feature introduces network management support for ERM through the use of ERM-MIB table entries, MIB objects, and MIB trap notification objects that are defined in CISCO-ERM-MIB.my.

To use the ERM-MIB feature, you should understand the following concepts:

•ERM Show MIB Objects

•ERM Configuration MIB Objects

•ERM Notification MIB Objects

ERM Show MIB Objects

The ERM Show MIB objects are read-only objects. You can use these MIB objects to obtain information about resource owners, resource user type, resource users or groups, resource owner and resource user relationships, and resource monitors in the system.

Table 1 describes the ERM Show MIB objects.

This section contains the following procedures:

•Enabling ERM-MIB Notification Traps

•Configuring the Router to Send SNMP Notification Traps for ERM to a Host

Enabling ERM-MIB Notification Traps

You can enable ERM-MIB notification traps, which are generated when resource usage exceeds the threshold value that is configured through the CLI. The ERM-MIB notification traps will be sent to the host that is configured to receive traps.

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp-server enable traps resource-policy

4. end

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	snmp-server enable traps resource-policy Example: Router(config)# snmp-server enable traps resource-policy	Enables CISCO-ERM-MIB notifications.
Step 4	end Example: Router(config)# end	Returns the router to privileged EXEC mode.
