/mcpExternal QoS Support In order for Cisco Unified Communications Manager to use the APIC-EM to manage media flows, the External QoS parameter must be enabled at both the system level, via a clusterwide service parameter, and at the device level, via the SIP Profile. APIC-EM Controller Prerequisites Before using APIC-EM, you must do the following: • Configure DSCP priority for different SIP media flows in Cisco Unified Communications Manager. For details, see DSCP Settings Configuration Task Flow, on page 773. • Configure the APIC-EM controller hardware within your network. For details, see the hardware documentation that comes with the APIC-EM controller. APIC-EM Controller Configuration Task Flow Complete these tasks on Cisco Unified Communications Manager to enable APIC-EM Controller to manage SIP media flows. Procedure Purpose Command or Action Configure Unified CM on the APIC-EM Controller. Configure the APIC-EM Controller, on page 809 Step 1 Upload the APIC-EM certificate into Cisco Unified OS Administration. Upload APIC-EM Controller Certificate, on page 809 Step 2 Configure an HTTP Profile that points to the APIC-EM service. Configure HTTPS Connection to APIC-EM Controller, on page 810 Step 3 Enable the External QoS Enable service parameter to configure the system to use the Enable External QoS Service for System, on page 810 Step 4 APIC-EM to manage media flows. The service parameter must be enabled for devices to use the APIC-EM for SIP media flow management. Note You must also enable external QoS within the SIP Profile for devices that will use the APIC-EM for SIP media flow management. Enable external QoS within a SIP Profile. All devices that use this SIP Profile will be able to use the APIC-EM to manage SIP media flows Configure External QoS Service at SIP Profile Level, on page 811 Step 5 Feature Configuration Guide for Cisco Unified Communications Manager, Release 15 and SUs 808 QoS Management APIC-EM Controller Prerequisites
