Network > SNMP

SNMP allows you to manage and/or monitor devices on the Q-LAN network for conditions that may need attention. With a third-party Management Information Base (MIB) browser, you can poll any Q-SYS Core, which returns its status as well as the status of any Q-SYS peripheral devices included in the running design. Additionally, third-party devices monitored via Enterprise Manager-enabled plugins or the Monitoring Proxy component also report their statuses via the Core using SNMP.

Note: SNMP is disabled by default on new Q-SYS Core processors and those that have been factory reset.

Configuring SNMP Access

Depending on the MIB browser you select, you can access the Q-SYS information using SNMP v2c and/or SNMP v3.

Note: The parameters you specify in Network Services > SNMP must be the same values you specify in the MIB browser.

Click Edit to modify SNMP access parameters.

  • Access: Select SNMP v2c access is Disabled, Read Only, or Read/Write.
  • Community: Specify the v2c community text string.
  • Access: Select whether SNMP v3 access is Disabled, Read Only, or Read/Write.
  • User: The SNMP v3 username string.
  • Security Level: Select from:
    • No Authorization – Only a username is required.
    • Authorization No Privacy – Requires a password, and allows selection of an Auth Protocol.
    • Authorization and Privacy – Adds another layer of security using a Privacy Password and Encryption.
  • Password: The password for authorization, which is encrypted and masked. The password must be a minimum of 8 characters.
  • Auth Protocol: The protocol for encrypting the signature attached to the SNMP message, either MD5 or SHA.
  • Privacy Password: This password is used with the 'Authorization and Privacy' security level, which encrypts the entire SNMP message. The password is encrypted and masked, and must be a minimum of 8 characters.
  • Encryption: Select an encryption type, either DES or AES.

Loading the MIB File

Load the Q-SYS MIB into a MIB browser to access the Q-SYS SNMP objects by name. You can put the MIB anywhere as long as the MIB browser has access to the location.

You can obtain the MIB file from:

  • The Q-SYS Designer installation directory: C:\Program Files\QSC\Q-SYS Designer\SNMP
  • The QSC website (https://www.qsc.com) – search for "MIB".

Inventory Table

Each device in the Q-SYS design's Inventory has an entry with the following objects:

  • invDeviceName (Read Only) – the name of the Inventory device
  • invDeviceType (Read Only) – the type of Inventory device (Core, Peripheral, Page Station, Amplifier, etc. )
  • invDeviceModel (Read Only) – the specific model of the Inventory device
  • invDeviceLocation (Read Only) – the Location of the Inventory device
  • invDeviceStatus (Read Only) – the Status string
  • invDeviceStatusValue (Read Only) – the Status value. (See Status for possible values.)

Snapshot Table

Each Snapshot Bank has an entry with the following objects:

  • ssSnapshotName (Read Only) – the Name of the Snapshot Bank.
  • ssSsTotalSnapshots (Read Only) – the total available snapshots in the Snapshot Bank.
  • ssActiveSnapshot (Read/Write) – Sets the active Snapshot.
  • ssRampTimeSec (Read/Write) – Sets the time it takes for the controls to reach the saved position or value (in seconds).

Note: For all other Q-SYS SNMP objects, see the MIB file.
