QoS/Traffic Shaping
The Cisco Unified Communications 500 Series IP-PBX supports DSCP
and will mark packets for prioritization if Traffic Shaping is configured
and active. Once enabled, signaling (SIP) is marked with DSCP CS4
and media (RTP) is marked with DSCP CS5.
DSCP QoS is honored through MegaPath's network. If Internet
connectivity is provided by an off-net third party then Quality of
Service cannot be guaranteed. Other providers may or may not honor
DSCP packet marking and standard best practice is to strip the ToS
byte at the provider's network edge.
Note – Traffic Shaping MUST be configured and active in order to
activate DSCP marking and utilize QoS prioritization across MegaPath's
network.
To configure the Cisco UC 500 Series for DSCP marking, please follow
the steps outlined below:
1. Navigate to Configure Routing Internet Connection
2. Under "WAN Interfaces", FastEthernet0/0 should be listed, select
this interface and click "Modify"
3. The "Modify Internet Connections" window should display, click the
"Traffic Shaping" tab
