Cisco Systems EA6500 Manual De Usuario

Threshold 0 is a nonconfigurable 100-percent tail-drop threshold on these port types:

1p1q0t (receive)

1p1q8t (receive)

1p3q1t (transmit)

1p2q1t (transmit)

The standard queue thresholds can be configured as either tail-drop or WRED-drop thresholds on 
these port types:

1p1q8t (receive)

1p3q1t (transmit)

See the 

 for more 

information about configuring thresholds as either tail-drop or WRED-drop.

To map CoS values to the standard receive-queue thresholds, perform this task: 

This example shows how to map the CoS values 0 and 1 to threshold 1 in the standard receive queue for 
Gigabit Ethernet port 1/1:

Router# configure terminal 

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)# interface gigabitethernet 1/1 

Router(config-if)# rcv-queue cos-map 1 1 0 1 

Router(config-if)# end 

Router# 

This example shows how to verify the configuration:

Router# show queueing interface gigabitethernet 1/1 

<...Output Truncated...>

    queue thresh cos-map

    ---------------------------------------

    1     1      0 1 

    1     2      2 3 

    1     3      4 5 

    1     4      6 7

<...Output Truncated...>

Router# 

Router(config)# interface {fastethernet | 

} slot/port 

Selects the interface to configure.

Router(config-if)# rcv-queue cos-map queue_# 

threshold_# cos1 [cos2 [cos3 [cos4 [cos5 [cos6 

[cos7 [cos8]]]]]]] 

Maps CoS values to the standard receive queue 
thresholds. 

Router(config-if)# no rcv-queue cos-map 

Reverts to the default mapping.

Router(config-if)# end 

Exits configuration mode.

Router# show queueing interface {fastethernet | 

} slot/port 

Verifies the configuration.
