Using the Nortel Application Switch Element Manager

Overview

The Nortel Application Switch Element Manager (ASEM) provides a graphical user interface (GUI) for remotely managing a Nortel Application Switch through the Simple Network Management Protocol (SNMP). This document provides an overview of how to use the ASEM.

The following topics are covered in this book:

•

"Setting ASEM Properties" (page 5)

• "Opening a Switch" (page 8)

•

"The ASEM Interface" (page 13)

•

"Switch Conﬁguration Tools" (page 35)

• "Monitoring Performance" (page 40)

•

"Customizing the ASEM Display" (page 42)

Setting ASEM Properties

ASEM uses the Simple Network Management Protocol (SNMP) to conﬁgure and manage a Nortel Application Switch. The ASEM Properties screen is used to conﬁgure parameters used to communicate with a switch. These parameters include polling interval, time-out, and retry count. These parameters are set at any time before or after a device is opened.

To set the properties in the ASEM Properties screen, follow this procedure:

Step Action 1

From the ASEM menu, select Nortel ASEM > Properties. This screen is illustrated in "Properties Screen" (page 6).

Opening a Switch

ASEM provides two options for opening a switch for conﬁguration and management. A switch can either be opened using SNMP versions 1 or 2, or SNMP version 3. The following sections explain how to open a switch through either of these methods.

If checked, the switch synchronizes the SLB, filter, and

VRRP configuration on a peer switch on Apply. To take

effect, peers must be configured on the switches and the

administrator password on the switches must be identical.

Note: This field supports only a single e-mail address. To send an e-mail notification to multiple addresses, create a mail list for those addresses.

Opening a Switch Using SNMP versions 1 or 2

To open a switch using SNMP versions 1 or 2, follow this procedure:

Step Action 1

From the menu, select Nortel ASEM > Open. The Open Device screen opens. This screen is illustrated in "Open Device screen"
