Chapter 1 Configuring SNMP Monitoring
Specifying the SNMP Community String
Step 4 Enter the hostname or IP address of an SNMP trap host, SNMP community or user name, security model
to send notification, and retry count and timeout for inform requests.
Step 5 Click Submit.
To specify the SNMP host from the CLI, you can use the snmp-server host global configuration
command.
Specifying the SNMP Community String
An SNMP community string is the password used to access an SNMP agent that resides on WAAS
devices. There are two types of community strings: group and read-write. Community strings enhance
the security of your SNMP messages.
Community strings are listed in the order in which they have been created. The maximum number of
SNMP communities that can be created is ten. By default, an SNMP agent is disabled, and a community
string is not configured. When a community string is configured, it permits read-only access to all agents
by default.
To enable the SNMP agent and configure a community string to permit access to the SNMP agent, follow
these steps:
Step 1 From the WAAS Central Manager menu, choose Devices > device-name (or Device Groups >
device-group-name).
Step 2 Choose Configure > Monitoring > SNMP > Community. The SNMP Community Strings window
appears.
