SNMP IP Setting
Simple Network Management Protocol (SNMP) is a communication protocol
designed specifically for managing devices on a network. SNMP is typically used to
configure devices for proper operation in a network environment, as well as to
monitor them to evaluate performance or detect potential problems.
The gateway includes an agent that supports SNMP version 1 and 2c access. A
network management station can access the gateway using SNMP management
software. To implement SNMP management, the gateway must first have an
assigned IP address and subnet mask.
Access to the gateway using SNMP v1 and v2c is controlled by community strings.
To communicate with the gateway, the management station must first submit a valid
community string for authentication. In addition, the SNMP management station IP
must be configured on the gateway to permit SNMP access.
The default community strings for the gateway are “public” for read-only access, and
“private” for read/write access. The default community strings can be changed only
through SNMP management software.
