ES4710BD 10 Slots L2/L3/L4 Chassis Switch
Example:
Configuring Ethernet port 1/1 to trust CoS value, i.e., classifying the packets according to
CoS value, DSCP value should not be changed.
Switch(Config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)#mls qos trust cos pass-through-dscp
16.2.2.11 mls qos cos
Command: mls qos cos {
<default-cos>
}
no mls qos cos
Function:
Configures the default CoS value of the port; the “
no mls qos cos
” command restores the
default setting.
Parameters:
< default-cos>
is the default CoS value for the port, the valid range is 0 to 7.
Default:
The default CoS value is 0.
Command mode:
Interface Mode
Usage Guide:
Example:
Setting the default CoS value of Ethernet port 1/1 to 5, i.e., packets coming in through
this port will be assigned a default CoS value of 5 if no CoS value present.
Switch(Config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)#mls qos cos 5
16.2.2.12 service-policy
Command: service-policy {input <
policy-map-name>
| output <
policy-map-name>
}
no service-policy {input <
policy-map-name>
| output <
policy-map-name>
}
Function:
Applies a policy map to the specified port; the “
no service-policy {input
<
policy-map-name>
| output <
policy-map-name>
}
” command deletes the specified
policy map applied to the port.
Parameters:
input <
policy-map-name>
applies the specified policy map to the ingress of switch
port;
output <
policy-map-name>
applies the specified policy map to the egress of
switch port.
Default:
No policy map is bound to ports by default.
Command mode:
Interface Mode
Usage Guide:
Configuring port trust status and applying policy map on the port are two conflicting
operations; the later configuration will override the earlier configuration. Only one
policy map can be applied to each direction of each port. Egress policy map is not
supported yet.
Example:
Binding policy p1 to ingress of Ethernet port 1/1.
Switch(Config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)# service-policy input p1
