New Features in IPM 4.1

The following are the new features and enhancements in Internetwork Performance Monitor (IPM) 4.1:

10000 Collector Support

IPM now supports 10000 collectors. You can create maximum of 5000 historical collectors and the remaining as real-time collectors. This is based on the LMS license you have opted for.

For more information, see Collector License Information.

Device Auto Allocation

The device allocation in IPM has been enhanced to include two new methods for auto allocation:

•Manage All Devices — Allows you to automatically add devices into IPM after they are added to DCR.

•Manage By Groups — Allows you to automatically add devices into IPM based on device groups.

However, the number of devices added into IPM will depend on the license limit.

For more information on Device Auto Allocation, see Auto Allocation Settings.

•ethernetPing

•ethernetPingAutoIPSLA

DNS Server Name

You can enter the Hostname or the IP Address for the DNS Server. For more information, see Defining an HTTP Operation.

Microseconds Accuracy

You can collect the jitter statistics for a UDP Jitter Operation at a precision level of microseconds. For more information, see Defining a UDP Jitter Operation.

Reaction Types for each Operation

IP SLA can be configured to react to certain measured network parameters. IPM now allows to create collectors in such a way to react to various Reaction parameters such as RTT, MOS, ICPIF, packet loss, etc.

Whenever the threshold levels are violated for any of the reaction variable configured, SNMP traps are sent to the configured management stations.

For more information on Reaction types, see Specifying Reaction Types.
