● For SNMP v3: In the SNMPv3 Users table (see Configuring SNMP V3 Users), configure
an SNMPv3 user for authentication and privacy.
4. In the SNMP Trap Destinations table (see Configuring SNMP Trap Destinations with IP
Addresses), configure OVOC (defined by IP address and port) as the destination to where the
device sends traps. You also need to specify the SNMP user that you configured in the
previous step and enable the row, as shown in the example below:
5. Configure the local SNMP port on the device to 161, using the SNMPPort ini file parameter.
6. Reset the device with a save-to-flash for your settings to take effect.
Configuring the OVOC Server for QoE
The Quality of Experience Settings table lets you configure a One Voice Operations Center
(OVOC) server to where the device can report QoE voice metrics. The device can report QoE to a
single OVOC server or to two OVOC servers deployed in a Geographic Redundancy, High-
Availability (HA) mode. Geographic Redundancy is when each OVOC server is in a different subnet
and has its own IP address. For the device to report QoE to both servers, you need to configure the
address of each server (IP address or FQDN). For normal HA mode, when both OVOC servers are
in the same subnet, a single OVOC server (global, virtual) address is used for all network
components (OVOC clients and managed devices). In such a setup, you need to configure only this
address.
You can also configure the device to use a TLS connection with OVOC. Before you can do this,
configure a TLS Context (certificate) in the TLS Contexts table (see
Configuring TLS Certificate
Contexts ). If no TLS Context is specified, the device uses the default TLS Context (ID 0). You can
also configure at what stage of the call the device sends the QoE report to OVOC. The report can
be sent during the call or only at the end of the call. Reporting at the end of the call may be
beneficial when there is network congestion as this reduces bandwidth usage over time.
If a QoE traffic overflow is experienced between OVOC and the device, the device
sends the QoE data only at the end of the call, regardless of your settings.
The following procedure describes how to configure the OVOC server for QoE through the Web
interface. You can also configure it through ini file [QOESettings] or CLI (
configure voip >
qoe qoe-settings
).
➢
To configure the OVOC server for QoE:
1. Open the Quality of Experience Settings table ( Setup menu > Signaling & Media tab >
Media folder > Quality of Experience > Quality of Experience Settings ).
2. Configure the OVOC server according to the parameters described in the table below.
