Chapter 4: Managing Your Appliance 49

In this dialog box, you can enter system information and community strings. You may also designate which stations can manage the appliance as well as receive SNMP traps from the switch. For more information on traps, see Enabling individual SNMP traps in this chapter. If you check Enable SNMP, the unit will respond to SNMP requests over UDP (User Datagram Protocol) port 161. Port 161 is the standard UDP port used to send and receive SNMP messages.

If you enter one or more allowable managers, only those IP addresses will be able to manage the appliance via SNMP. If you do not enter any allowable managers, then the appliance can be managed via SNMP from any IP address.

NOTE: The AMP uses SNMP within a secure tunnel to manage appliances. For this reason, UDP Port 161 need not be exposed on firewalls. You will need to expose UDP Port 161 to monitor Avocent appliance via third-party SNMP-based management software.

Figure 4.5: SNMP Configuration Dialog Box

To configure general SNMP settings:

1.Click the SNMP category in the left column in the AMP.

2.Click the Enable SNMP checkbox to allow the appliance to respond to SNMP requests over UDP port 161.

3.Enter the system’s fully qualified domain name in the Name field, as well as a description and node contact person in the System section.

4.Enter the Read, Write and Trap community names. These specify the community strings that must be used in SNMP actions. The Read and Write strings only apply to SNMP over UPD port 161 and act as passwords that protect access to the appliance. The values can be up to 64 characters in length.
