Revision 1.1
WebSwitch™ Users Manual
SNMP
Simple Network Management Protocol (SNMP) is used to manage and administer network devices.
WebSwitch™ supports SNMP V1.0 and can be configured here. Using SNMP, the input and power outlet
states of WebSwitch™ can be read as well as some basic information about the device. See
Appendix
F
:
SNMP Requests
for information about how to request information from WebSwitch™ using an SNMP
manager, as well as where to find MIB files for WebSwitch™.
Note: The read and write community strings used for SNMP are actually the control password found on
the
Password
setup tab (see Section 2.4.4). If the control password is disabled, then WebSwitch™
does not check for the community string when issued a Get or Get Next request from the SNMP
manager.
SNMP Enabled
When this option is set to
Yes
,
WebSwitch™ will support SNMP. The default setting for this option is
No
.
SNMP Manager IP
When SNMP is used, this field is used to specify the IP address of the SNMP manager. The default
setting for this field is
192.168.1.25
.
SNMP Port
When SNMP is used, this field is used to specify the SNMP port that WebSwitch™ listens on. The
default setting for this field is
161
.
SNMP Trap Port
When SNMP is used, this field is used to specify the SNMP Trap port of the SNMP manager. The
default setting for this field is
162
.
IP Filter Range 1 and IP Filter Range 2
For additional security, WebSwitch™ has a simple built-in firewall. If desired, WebSwitch™ can be
configured to only allow access to client devices (computers, servers, other ControlByWeb™
devices, etc) with certain IP addresses. Two IP address ranges are provided and only client devices
with addresses that fall within those two ranges will be allowed to communicate. Devices with IP
addresses that fall outside of those ranges will not receive any response from WebSwitch™.
Example:
To allow access from any device (this is the default setting):
IP Filter Range 1:
0.0.0.0
255.255.255.255
IP Filter Range 2:
0.0.0.0
0.0.0.0
To limit access to only one device (address 192.168.1.33):
IP Filter Range 1:
192.168.1.33
192.168.1.33
IP Filter Range 2:
0.0.0.0
0.0.0.0
