Configuring Communication Settings for Newly Discovered Devices

You can configure AirWave to communicate with your devices by defining default shared secrets and SNMP settings. In order for AirWave to configure the devices, community strings and shared secrets must have read-write access.

To configure communication settings for newly discovered devices:

1. Go to Device Setup > Communication page, then scroll down the page.
2. Enter the following SNMP settings:
   • SNMP Timeout. The length of time (three to 60 seconds) that AirWave waits for a response from a device after sending the device an SNMP request. The default time is three seconds.
   • SNMP Retries. The number of times (one to 40) that AirWave polls a device when the device doesn't respond to an SNMP request. Optionally, AirWave uses the number of times set for the device group by the Missed SNMP Poll Threshold option. AirWave will classify the device as being down if the device doesn't respond after reaching this number. If an SNMP library has a limit of 20 retries, AirWave will stop at 20. The default is three times.
3. Click Add, then enter the following information for the SNMPv3 user:
   • Username. User name of the SNMPv3 user, as it is configured on the controller. The SNMP Inform receiver will restart when users are changed or added to the controller.
   • Auth Protocol. MD5 or SHA. The default setting is SHA.
   • Auth Passphrase. Authentication and privilege protocol passphrase for the SNMPv3 user, as it is configured on the controller. Re-enter the passphrase.
   • Priv Protocol. The symmetric-key algorithm used to encrypt data, Data Encryption Standard (DES) or Advanced Encryption Standard (AES). The default standard is DES.
   • Priv Protocol Passphrase. Privilege protocol passphrase for the SNMPv3 user, as it is configured on the controller. Re-enter the passphrase.
4. For the Telnet/SSH Timeout option, enter the timeout period (zero to 600 seconds) to apply when performing Telnet and SSH commands. The default timeout is 10 seconds.
5. For the HTTP Timeout option, enter the timeout period (three to 120 seconds) used when running an HTTP discovery scan. The default timeout is five seconds.
6. For the Attempt to ping devices that were unreachable via SNMP option, select No if ICMP is disabled on the network. By default, this option is enabled. When there are more than 100 devices, and many are unreachable by ICMP, the timeouts will impede network performance, and you should turn off this option.
7. For Symbol 4131 and Cisco IOS devices that don't have SNMP initialized, select one of the following options:
• Do not modify SNMP settings. AirWave will not modify any SNMP settings for these devices when you select this option. By default, this option is enabled.
• Enable read-write SNMP. AirWave will manage these devices using SNMP when you select this option. By default, this option is disabled.
