Configuring QoS

The no option allows you to withdraw a previously configured Egress Encode EXP Policy Map. If the
qos exp encode-policy default-map command is not configured, the no qos exp encode-policy
default-map command will still be allowed because qos exp encode-policy default-map is the
default configuration.
Binding an Egress Encode EXP Policy Map to a port
You can bind an Egress Encode EXP Policy Map to a specified port on a Brocade device using the
qos exp encode-policy command as shown in the following.
Brocade(config)# interface ethernet 10/1
Brocade(config-if-e10000-10/1)qos exp encode-policy Customer1
Syntax: [no] qos exp encode-policy encode-map-name | default-map | all-zero-map
The encode-map-name variable is the name assigned to the Egress Encode EXP Policy Map that
you want applied to the port whose configuration this is under:
The default-map option assigns the default Egress Encode EXP Policy Map to the port whose
configuration this is under. Since the default Egress Encode EXP Policy Map is the default setting,
this option is only required when the device’s global policy map has been set to an Egress Encode
EXP Policy Map other than the default. The qos exp encode-policy default-map command will not be
displayed within the configuration unless it is explicitly configured.
The all-zero-map option assigns an Egress Encode EXP Policy Map where all 32 combinations of
priority and drop precedence are mapped to 0.
The no option allows you to withdraw a previously configured encode policy. If the qos exp
encode-policy default-map command is not configured, then the no qos exp encode-policy
default-map command will generate an error message because the qos exp encode-policy
default-map command was never configured on the port.
Enabling and disabling an Egress Encode EXP Policy Map on a port
To enable or disable an Egress Encode EXP Policy Map on a port, use the qos exp encode-policy
command as shown in the following.
Brocade(config)# interface ethernet 10/1
Brocade(config-if-e10000-10/1)qos exp encode-policy on
Syntax: [no] qos exp encode-policy on | off
The on option enables EXP encode on the port. This is the default setting. The qos exp
encode-policy on command will not be displayed within the configuration unless it is explicitly
configured.
The off option disables EXP encode on the port.
Enabling a port to use the DEI bit for Ingress
and Egress processing
In the IEEE 802.1ad specification, two types of tag are defined:
• Customer VLAN tag (C-TAG)
• Service VLAN tag (S-TAG)
