The Services > SNMP page configures the access point to work with
the NMS station
. In addition to
enabling SNMP, the SNMP community must be configured. The SNMP community string
is used like a username and is for authentication, privacy, and authorization
services within SNMP
. When a
SNMP Community name is entered on the Express Setup page, the community
associates using read-only or read/write capabilities.
The SNMP Request
Communities section is not enabled until Enabled is selected in the Simple
Network Management Protocol (SNMP) field at the top of the screen and click
Apply. The descriptions are shown in Figure
.
The SNMP
Trap Community section is not enabled until Enabled is selected in the Simple
Network Management Protocol (SNMP) field at the top of the screen and click
Apply
.
With
VxWorks based APs and bridges, use the SNMP Setup page shown in Figure
to configure the
device to work with the network SNMP management station. Most of the setting
are the same as the IOS.
The default SNMP settings are shown in Figure
.
To
disable SNMP via IOS, use the no snmp-server to disable the
SNMP agent operation.
The SNMP community string is used to define the
relationship between the SNMP manager and the agent. The community string acts
like a password to permit access to the agent on the access point. The
associated string characteristics can be configured with the following:
- An access list of IP addresses of the SNMP managers that are permitted to
use the community string to gain access to the agent
- A MIB view, which defines the subset of all MIB objects accessible to the
given community
- Read and write or read-only permission for the MIB objects accessible to
the community
Beginning in configuration mode, use the command in Figure
to configure a
community string on the access point. Though visible in the command-line help
string, the version 3 keyword (SNMPv3) is not supported.
The SNMP traps are shown in Figure
. Follow the
steps in Figure
to configure the AP to send traps to a host. Follow the steps in
Figure
to set the
system contact and location of the SNMP agent so that these descriptions can be
accessed through the configuration file.
After the device SNMP settings are complete, an SNMP NMS application server
must be installed. This will be covered next.
