Upload Log File

The following window is used to upload log files from SIM member switches to a specified PC. To upload a log file,
enter the Server IP address of the SIM member switch and then enter a Path\Filename on your PC where you wish to
save this file. Click Upload to initiate the file transfer.

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 Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of security
provided between the management station and the network device.
In SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which 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 are ignored (dropped).
The default community strings for the Switch used for SNMP v.1 and v.2 management access are:
•
public – Allows authorized management stations to retrieve MIB objects.
•
private – Allows authorized management stations to retrieve and modify MIB objects.
SNMPv3 uses a more sophisticated authentication process that is separated into two parts. The first part is to maintain
a list of users and their attributes that are allowed to act as SNMP managers. The second part describes what each
user on that list can do as an SNMP manager.
