CAUTION: Do not start the ATM and VLAN Network Manager until all the ATM and VLAN devices have been discovered and appear in the IP Map of the management platform.
Setting Up for Polling in SNMP management is the activity whereby the NMS
Distributed Polling interrogates/polls individual nodes on the network for their current status. It is one if the most important sources of network management control for traffic on the network.
The ATM and VLAN Management application maintains the status and state of all the logical and physical components of the network. You cannot rely on the platform poller alone (such as HPOV SNMP Poller) which only maintains the “ping” status of the network when using the application. The ATM and VLAN Management application uses a
Starting the Poller Locally
In small networks consisting of less than a 100 network devices (ATM and
Starting the Poller on Multiple Distributed Machines
When using the application to manage a larger network, consisting of many network devices, or when the network is managed over a wide area, it is possible to distribute the polling.
Distributing polling onto more than one machine has several advantages.
The advantages are:
■Localizes polling in remote sites so as not to send polling traffic on WAN links.
■Distributes the polling load onto several machines to get better polling performance and SNMP traffic distribution.
■Frees up CPU resources on the central management station, thus providing better console performance.
