SNMP
Simple Network Management Protocol (SNMP) exchanges messages between a management client and a
management agent. Messages contain requests to get and set variables that exist in network nodes, thus
allowing a management client to obtain statistics, set configuration parameters, and monitor events.
Communication with the SNMP agent can occur over the LAN or WAN connection. To configure SNMP:
1. Click
SNMP
on the left navigation pane of the Router Information Page. This displays the SNMP
Configuration page.
2. In
Community String
, enter the name of the SNMP community to which the router belongs. This name
acts as a identifier between the SNMP manager and agent for requests. The community setting allows the
SNMP manager to request information from a
community
, rather than each node (agent) individually.
3. In Write Communicty String, enter the name of the SNMP write community to which the router belongs.
4. In
Port Number
, select one of the following:
•
Port Number
:
Enter the desired number in the field next to
Port Number
.
•
Disable
:
Disables the SNMP port.
•
Default
:
Sets the port to the default port of 161.
5. In
Enabled Interfaces
, select one or both of the following:
•
LAN designates the Local Area Network as a trusted interface.
•
WAN designates the Wide Area Network as a trusted interface.
6. In
Trap Enable
, select
Enable
or
Disable
. SNMP agents also have the ability to send (unrequested)
messages to SNMP managers; these messages are called traps and notify the SNMP managers that an
event has happened on the system.
7. If you enabled
Trap Enable
, in
Trap Manager[1-4]
specify the IP address for a node that will receive a
Trap event from the router. You can specify up to four trap managers.
8. Click
Apply
.
9. Configure
SNMP IP Filter
and
SNMP Password
.
