Mode: Configure
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
cos command is used, with one of the following arguments:
• 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.
Step Command Purpose
1 node(config)#port ethernet slot port Enter Ethernet port configura-
tion.
2 node(prt-eth)[slot/port]#vlan id Create new VLAN port.
3 node(vlan)[id]#encapsulation {ip|pppoe|multi} 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 30, “PPP configuration”
on page 313.
4 node(vlan)[id]#bind interface name [router] 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.
5 node(vlan)[id]#map cos layer-2-CoS-value to traffic-class-name Selects the layer 2 CoS (Class of
Service) to traffic class map-
ping. The traffic class must
already exist.
6 node(vlan)[id]#no shutdown Activate the VLAN port.
7 node(vlan)[id]#exit node(prt-eth)[slot/port]# no shutdown Make sure the hosting Ethernet
port is also activated.
