Enabling SNMPv1/v2c on the Wireless Controller

1. From the top menu, click Controller.
2. In the left pane, click Network > SNMP.
   The SNMP Common Settings screen is displayed.

   

   
3. To enable SNMP, select the SNMPv1/v2c Mode option.
4. 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.
5. In the Forward Traps drop-down list, click the security level of the traps to be forwarded: Informational, Minor, Major, or Critical.
6. 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.

7. In the SNMP v1/v2c section, type the following:
   • Read Community Name – Specifies the community name password for users with read privileges.
   • Read/Write Community Name – Specifies the community name password for users with read and write privileges.
   • Manager A – Specifies the IP address of the server on the network where the SNMP traps are monitored.
   • Manager B – Specifies the IP address of a second server on the network where the SNMP traps are monitored.
     

     Warning

     For security purposes, it is recommended that you immediately change the Read Community Name (public) and the Read/Write Community Name (private) passwords to names that are less obvious and more secure.
8. To save your changes, click Save.
