Enabling SNMPv3

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 (Simple Network Management Protocol), select the SNMPv3 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 v3 section, type the SNMP engine ID in Engine ID. The SNMP engine ID is a 5 – 32 character ID for the EWC SNMP agent. Do not use spaces, control characters, or tabs.
8. Add user accounts.
   1. Click Add User Account.
      The Add SNMPv3 User Account screen is displayed.

      

      
   2. Select Enabled to enable the user.
   3. In User Name, type a user name.
   4. In the Security Level drop-down list, select the appropriate security level for the user: authPriv, authNoPriv, NoAuthNoPriv.
      If NoAuthNoPriv is selected, click OK and go to the next step.
   5. In the Authentication Protocol drop-down list, select the authentication protocol: None, MD5 (Message-Digest algorithm 5), SHA.
   6. In Authentication Password, type the password, which must be at least eight characters long. If desired, click Unmask to display the password in plain text.
      If authNoPriv is the selected security level, click OK and go to the next step.
   7. In the Privacy Protocol drop-down list, select the encryption protocol: None, DES.
   8. In Privacy Password, type the password, which must be at least eight characters long. If desired, click Unmask to display the password in plain text.
   9. Click OK to save the user account information. The SNMP Common Settings screen is displayed.
9. In Trap 1 Destination IP and Trap 2 Destination IP, type the IP addresses of the servers on the network where the SNMP traps are monitored.
10. In the Trap 1 User Name and Trap 2 User Name drop-down lists, select the user name associated with the Trap 1 and Trap 2 destination servers. Only enabled users appear in these drop-down lists.
11. To save your changes, click Save.
