Ping Test

Ping is a small program that sends ICMP Echo packets to the IP address you specify. The destination
node then responds to or "echoes" the packets sent from the Switch. This is very useful to verify
connectivity between the Switch and other nodes on the network.
Figure 6- 19. Ping Test window
The user may use Infinite times radio button, in the Repeat Pinging for field, which will tell the ping
program to keep sending ICMP Echo packets to the specified IP address until the program is stopped.
The user may opt to choose a specific number of times to ping the Target IP Address by clicking its
radio button and entering a number between 1 and 255. Click Start to initiate the Ping program.

SNMP Manager

SNMP Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) 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.
The DES-3800 Series supports the SNMP versions 1, 2c, and 3. The default SNMP setting is disabled.
You must enable SNMP. Once SNMP is enabled you can choose which version you want to use to
monitor and control the Switch. The three versions of SNMP vary in the level of security provided
between the management station and the network device.
