AT-VP504E FXS 6
What is SNMP? The AT-VP504E FXS uses the Simple Network Management Protocol
(SNMP) for initial software configuration provisioning and subsequent
software configuration.
SNMP is a simple request-reply protocol for Internet network
management services. It consists of
network management stations
(managers) communicating with
network elements
. The network
elements can be anything that run the TCP/IP protocol suite: hosts,
routers, X terminals (or in this case, an AT-VP504E FXS). The software
in the network element that runs the management software is called
the
agent
. Management stations are normally workstations that display
relevant facts about the elements being monitored.
SNMP works over the IP (Internet Protocol) communication stack.
The communication can be two ways: the manager asking the agent
for a specific value (“what is your designation?”), or the agent telling the
manager that something important happened (“the AT-VP504E FXS
has gone down”). Also, the manager can set variables in the agent in
addition to reading variables from the agent.
TCP/IP network management consists of three pieces:
1. A
Management Information Base
(MIB) that specifies what
variables the network elements maintain (the information that
can be queried and set by the manager). See “What is a
MIB?” on page 7 for more details.
2. A set of common structures and an identification scheme
used to reference the variables in the MIB. This is called the
Structure of Management Information
(SMI).
3. The protocol between the manager and the element, called
the
Simple Network Management Protocol
(SNMP). This
details the format of the packets exchanged. Although a wide
Default Settings switch The
Default Settings
switch resets configuration
parameters of the AT-VP504E FXS to default
(known values). It can be used to reconfigure
units.
Warning: Read Section “Using the Dual-Mode
Default Settings Switch” on page 22 before
attempting to reset the unit.
