Had a radio briefly showing an error in red on the web page saying “Bandwidth PLL lock lost” The radio seems to operate so not sure if it is an actual issue or maybe an ongoing bug.

Cambium Bandwidth PLL lock lost

These entries are from the cambium 16.1.1 Release Notes
https://community.cambiumnetworks.com/t/450-platform-series-release-16-1-1-is-now-available/65335

  • A very few 450i/450b SMs having “Bandwidth PLL lock lost” and being unable to register to AP on 20 and 30 MHz after upgrade to 16.1.
  • Occasional false positive of 450 radios was showing “Bandwidth PLL lock Lost” but operating normally.

The following template can be used to set the user name and passwords for cambium pmp gear. Create a new template in cnMaestro, past in the following, change the passwordEncrypted to the hash of your password and run the config.

You can get the hashed password by pulling it out of a current radio config.

{
"userParameters": {
  "authenticationConfig": {
    "accounts": [ 
      { 
        "userName": "admin", 
        "level": 3, 
        "readOnly": false, 
        "passwordEncrypted": "188a934e0246ae248da19400fed83107a" 
      }, 
      { 
        "userName": "root", 
        "level": 3, 
        "readOnly": false, 
        "passwordEncrypted": "188a934e0246ae248da19400fed83107a" 
      } 
    ]
  }

The following works for setting the snmpv3 configuration on cambium 450i 900’s. Once applied it’ll run change the SNMP settings and reboot the radio.

You’ll need to find the hashed password which can be found in a config backup.
Change the SNMP username/community as needed.
