Configuring layer 2 CoS to service-class mapping for an Ethernet port
To enable to transport real-time and delay sensitive services such as VoIP traffic across the network, the firm-
ware application software supports the delivery of Quality of Service (QoS) information in the ToS (Type of
Service) field. This is an eight-bit field, the second field in the IP header packet. To define the Class of Service
(CoS) to service class mapping, the
•
default—Default service class when no Layer 2 CoS present
•
rx-map—Receive mapping table - Layer 2 CoS to service class mapping
•
tx-map—Transmit mapping table - Service class to Layer 2 CoS mapping
This procedure describes how to change layer 2 CoS to service class mapping.
Ethernet port configuration task list
Command
cos
command is used, with one of the following arguments:
12 • Ethernet port configuration
Purpose
Enter Ethernet port configura-
tion.
Create new VLAN port.
Defines the payload type(s) to
be used on this VLAN:
• ip: IP traffic only (not used
for PPP)
• pppoe: PPPoE sessions only
• multi: both IP traffic and
PPPoE sessions
For more information on the
PPP/PPPoE configuration see
chapter 24,
"PPP configuration"
on page 264.
Bind the VLAN port to the exist-
ing interface name. If no IP con-
text is given, the system attaches
the interface to the default IP
context known as router.
Selects the layer 2 CoS (Class of
Service) to traffic class map-
ping. The traffic class must
already exist.
Activate the VLAN port.
Make sure the hosting Ethernet
port is also activated.
