The Cisco MGX 8260 Media Gateway reports alarm conditions using SNMP traps and email notifications. This chapter describes the process of setting up SNMP communities and choosing trap notifications.
To configure SNMP for alarm notifications, follow these steps:
Step 2 Register SNMP traps.
When managing the Cisco MGX 8260 Media Gateway from an SNMP manager, security is enforced with password-like community strings. SNMP communities are groupings of workstations and servers (or gateways) that can manage the Cisco MGX 8260 Media Gateway. You can configure as many as 15 community strings.
To view all community strings, follow these steps:
Step 2 Click SNMP.
Step 3 Click Community String.
The Community String screen opens.
Step 4 Interpret the table as follows:
| Displayed Information | Description |
|---|---|
Manager IP Address | The IP address of the manager associated with this string |
Community String | The name of the community string |
Privilege | The manager's privilege, either read-write or read-only |
To add a community string, follow these steps:
Step 2 Click SNMP.

The Community String screen opens.
Step 4 Click the + icon.
The Add Community String form opens.
Step 5 Enter the following parameters:
| Parameter | Description | Example |
