RSSI
Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the remote wireless device. In
general, remote APs with stronger signal will display higher RSSI values. For RSSI value, the smaller the
absolute value is, the stronger the signal. For example, “-50db” has stronger signal than “-80dB”. For outdoor
connection, signal stronger than -60dB is considered as a good connection.
RTS
Request To Send. A packet sent when a computer has data to transmit. The computer will wait for a CTS
(Clear To Send) message before sending data.
RTS Threshold
RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a frame if the packet frame is
larger than this value. Lower this value can improve the performance if there are many clients in your network.
You can try 1500, 1000 or 500 when there are many clients in your AP’s network.
SNMP
(Simple Network Management Protocol)
A set of protocols for managing complex networks. The SNMP network contains 3 key elements: managed
devices, agents, and network-management systems (NMSs). Managed devices are network devices that
content SNMP agents. SNMP agents are programs that reside SNMP capable device's firmware to provide
SNMP configuration service. The NMS typically is a PC based software such as HP Openview that can view
and manage SNMP network device remotely.
SSH
Developed by SSH Communications Security Ltd., Secure Shell is a program to log into another computer
over a network, to execute commands in a remote machine, and to move files from one machine to another. It
provides strong authentication and secure communications over insecure channels. It is a replacement for
rlogin, rsh, rcp, and rdist.
SSL
Secure Sockets Layer. It is a popular encryption scheme used by many online retail and banking sites to
protect the financial integrity of transactions. When an SSL session begins, the server sends its public key to
the browser. The browser then sends a randomly generated secret key back to the server in order to have a
secret key exchange for that session. SSL VPN is also known as Web VPN. The HTTPS and SSH
management interface use SSL for data encryption.
