Configuring Embedded Resource Manager-MIB
The Embedded Resource Manager (ERM)-MIB feature introduces MIB support for the ERM feature. The ERM feature tracks resource usage information for every registered resource owner and resource user. 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.

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:

You can enable ERM-MIB notification traps, which are generated when resource usage exceeds the threshold value. The ERM-MIB notification traps will be sent to the host that is configured to receive traps.
1.
enable
2.
configure
terminal
3.
snmp-server
enable
traps
resource-policy
4.
end
DETAILED STEPS
Configuring the Router to Send SNMP Notification Traps for ERM to a Host
Perform this task to enable the router to send SNMP notifications traps defined in ERM-MIB to a host.
SNMP must be enabled on your network.
Create an SNMP server community to receive information on MIB objects and traps using the snmp-server community command.
1.
enable
2.
show
running-config
[options]
3.
configure
terminal
4.
snmp-server
host
{hostname | ip-address} [vrf vrf-name] [traps | informs] [version {1 | 2c | 3 [auth | noauth | priv]}] community-string [udp-port port] [notification-type]
5.
