Enabling SNMPv3
To enable SNMPv3
parameters:
-
From the top menu, click
Controller.
-
In the left pane, click
.
The
SNMP Common Settings screen is displayed.
-
To enable SNMP, select the SNMPv3 Mode option.
-
Type the following information:
- Contact Name – Specifies
the name of the SNMP administrator.
- Location – Specifies the
location of the SNMP administration.
- SNMP Trap Port – Specifies
the destination port for SNMP traps. The industry standard is 162. If left blank,
no traps are generated.
-
In the Forward Traps drop-down list, click the security level of the traps to be forwarded: Informational, Minor, Major, or Critical.
-
In the Publish AP as interface of controller drop-down list, click to enable
or disable publishing the wireless AP and their interfaces as interfaces of the
controller. By default this option is enabled.
When this option is enabled,
all wireless APs and their interfaces are published as interfaces of the
controller when you retrieve topology statistics and configuration information
using SNMP.
Topology statistics and
configuration information on wireless APs are retrievable using both proprietary
and standard MIBs. The Publish AP as interface of controller option only affects
information retrieved through standard MIBs, i.e. IF-MIB, RFC1213. All information
that is retrieved through proprietary MIBs is not affected. If the Publish AP as
interface of controller option is disabled, the wireless APs' interfaces are not
considered interfaces of the controller.
For example, if the Publish AP
as interface of controller option is disabled, querying the ifTable would return
information on the controller physical interfaces, plus all VNSs that are
configured on that controller. If enabled, querying the same table would return
the above information, in addition to information on each wireless APs‘
interfaces.
