10.1 SNMP
Simple Network Management Protocol (SNMP) is designed specifically for managing and
monitoring network devices. SNMP enables network management stations to read and modify
the settings of gateways, routers, switches, and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential
problems in the Switch, switch group or network.
Managed devices that support SNMP include software (referred to as an agent), which runs
locally on the device. A defined set of variables (managed objects) is maintained by the
SNMP agent and used to manage the device. These objects are defined in a Management
Information Base (MIB), which provides a standard presentation of the information controlled
by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and
the protocol used to access this information over the network.
This switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the
level of security provided between management station and network device.
In SNMP v.1 and v.2c, user authentication is accomplished by using Community Strings,
whose function like passwords. The remote user SNMP application and the Switch SNMP
must use the same community string. SNMP packets from any station that has not been
authenticated will be ignored (dropped).
The default community strings for the Switch used for SNMP v.1 and v.2c management
access are:
public – Allow authorized management stations to read MIB objects.
private – Allow authorized management stations to read and write MIB objects.
