The Windows Internet Naming Service, (WINS) server, is used for name resolution. It is
similar in function to DNS. It allows you to search for resources by computer name instead of IP
address.
This software release has added the field: Lease period for the DHCP server function. The
lease times you can select are: 1 hour, 2 hours, 1 day, 2 days, or 1 week.
SNMP Agent
The SNMP agent setup page allows you to set up an SNMP agent. The agent is a software
module that collects and stores management information for use in a network management
system. The WAB-1000's integrated SNMP agent software module translates the device’s
management information into a common form for interpretation by the SNMP manager, which
usually resides on a network administrator’s computer.
The SNMP manager function interacts with the SNMP agent to execute applications to
control and manage object variables (interface features and devices) in the gateway. Common
forms of managed information include number of packets received on an interface, port status,
dropped packets, and so forth. SNMP is a simple request and response protocol, allowing the
manager to interact with the agent to either
• Get - Allows the manager to read information about an object variable
• Set - Allows the manager to write values for object variables within an agent’s control,
or
• Trap - Allows the manager to capture information and send an alert about some pre-
selected event to a specific destination
The SNMP configuration consists of several fields, which are explained below:
• Community –The Community field for Get (Read Only), Set (Read & Write), and Trap
is simply the SNMP terminology for “password” for those functions.
• Source –The IP address or name where the information is obtained.
• Access Control –Defines the level of management interaction permitted.
