Configure SNMP
When configuring an SNMP manager or SNMP agent, configure the SNMP manager first. Once all SNMP managers are configured, the SNMP agents can be created. If adding an SNMP Manager to an existing configuration, any SNMP agents configured will need to be removed and re-added after the new SNMP Managers are created.
Configure SNMP Manager
The IMG 2020 supports configuring up to three SNMP Managers on it.
Right click the External Network Elements and select New SNMP Managers. An SNMP Managers screen will appear. The SNMP managers object is a container or parent object and no configuration is needed here. Refer to the topic for more information.
Right click on SNMP Managers object and select New SNMP Manager. The SNMP Manager Screen will be displayed as displayed below. Refer to the SNMP Manager topic for more information on configuring this object.
Properties | Description |
SNMP Username | Enter a username that identifies this SNMP Manager. Click in the SNMP Username field and enter the name. |
SNMP Community Name | The SNMP Agent could require that an SNMP Manager send a particular password with each message. The SNMP Agent would then verify whether the SNMP Manager is authorized to access MIB information. This is used for security in SNMPv2. Most often there is one community string which is used for read-only access to an SNMP Agent. The default value for this community string is often "public". Using this community string like a password, the NMS can retrieve data from network elements. Click in the SNMP Community Name field and enter the name. |
SNMP Manager IP Address | Enter the IP address of the SNMP Manager. Click in the SNMP Manager IP address field and enter an IP address. |
SNMP Trap Port | The port that SNMP traps are received on. By Default port 162 is displayed as per standard RFCs for SNMP. To modify the port, highlight the SNMP Trap port and enter a different trap port number. |
SNMP Version | The version of SNMP is displayed here. Click in the SNMP version field and a drop down menu will display the two versions of SNMP the IMG 2020 supports. The IMG 2020 supports SNMPv1 and SNMPv2c. |
SNMP Timeout | The time to wait for an ACK from an SNMP Manager before timing out. The value entered will be in milliseconds. The default is set to 1500 ms (1.5 seconds). If value needs to be modified, highlight the default entry and enter the new value. |
Trap Retries | The number of times to resend a trap to the SNMP manager. The Default is three. To change, click in the Trap Retries field and select from drop down menu 0-5 |
Trap Notify Type | When the Trap Notify Type is set to "inclusive", the SNMP traps are sent. When the Trap Notify Type is set to "exclusive", the SNMP traps are not sent. This is done in the Trap Notify Type field. The two selections from the drop down menu are: inclusive - SNMP traps are sent. (Default) exclusive - SNMP traps are not sent. |
Configure SNMP Agent
Configure the SNMP Agent for all physical IMG 2020 nodes in your network. An SNMP agent can be configured for each IMG 2020 that will be monitored. In the Web GUI, right click on the IMG 2020 node object and select New SNMP Agent. A pane like below will appear.
Properties | Description |
SNMP System Name | The name that identifies the SNMP agent. The default name that appears is the name given the IMG 2020 node object. This can be modified to any name by highlighting the SNMP System Name entry and entering a different name. The SNMP System Name parameter will be printed in any traps that may occur. |
System Location | Enter a location for the SNMP Agent. Click in the System Location field and enter the location. The System Location parameter will be printed in any traps that may occur. |
System Contact | Enter a contact name to alert people who to contact in the case of an SNMP Trap being sent. The System Contact parameter will be printed in any traps that may occur. |
SNMP Agent Network Interface | Click in this field and a drop down menu displaying all interfaces configured on rear of IMG 2020 will appear. Select from drop down menu which interface the SNMP agent will be configured to communicate through. |
Repeat above steps for each IMG 2020 node that an SNMP Agent will get configured on.
