Clarification about how the EPICenter server works on a multi-homed device in

version 7.0 compared with previous EPICenter versions

A multi-homed device is one that has more than one network interface card (NIC) installed, and may be

using multiple IP addresses. When the EPICenter 7.0 server is installed on a multi-homed device, it

works differently from previous EPICenter versions:

● In EPICenter versions prior to 6.0, when installed on a multi-homed device, the EPICenter server

used all of the IP addresses that were bound to interfaces on the device.

● Starting with EPICenter 6.0, the EPICenter server uses only one of the IP addresses bound to

interfaces on the multi-homed device. This is usually the IP address bound to the lowest-numbered

interface on the device.

To set a different IP address for the EPICenter 7.0 server, you configure the

EPICENTER_SERVER_ADDRESS environment variable. See “Installing EPICenter on a Multi-Homed

Server” in the EPICenter Installation and Upgrade Guide for information about how to do this.

Alarm Manager

Polling timeouts can cause false SNMP unreachable alarms

If timeouts occur during EPICenter’s status polling or detail polling operations, an SNMP unreachable

alarm may be triggered, even though the device is reachable. This can cause numbers of false alarms.

To work around this, you can modify the SNMP unreachable alarm to use a repetitive occurrence

specification as follows:

1 In the Alarm Manager, go the Alarm Definition tab, and select the SNMP Unreachable alarm

2 Click Modify to display the Modify Alarm Definition window with the Basic tab displayed.

3 At the bottom of this window, check the box next to “If event happens” and then enter the number

of times the event must happen, and the timeframe within which these events must occur.

For example, you could set this so that the SNMP Unreachable event must occur 3 times within 30

minutes before the SNMP Unreachable alarm will be triggered.

4 Click OK to save these changes. These will take effect immediately if the alarm is enabled.

Alternatively, you could disable the alarm using the Modify alarm process. (PD3-30468254)
