Verifying Subinterface Configuration On A Vlan - Cisco ASR 1000 Series Software Configuration Manual

Configuring the Ethernet SPAs
Previous Behavior
When VLAN scale configuration is enabled using the hw-module subslot slot/subslot ethernet vlan unlimited
command, the VLAN custom COS configurations are lost. However, an informational message was not
displayed.
New Behavior
Effective from Cisco IOS XE Release 2.1.0S a warning message has been introduced when VLAN scale
configuration is enabled using the hw-module subslot slot/subslot ethernet vlan unlimited command,
suggesting that VLAN COS bits classification will be lost.
The following is a sample output of hw-module subslot slot/subslot ethernet vlan unlimited command
displaying a warning message.
Router(config)# hw-module subslot 1/3 ethernet vlan unlimited
%VLAN input classification in subslot 1/3 will not be available.
To specify VLAN classification, use the following commands in subinterface configuration mode:
Command
Router(config-subif)# plim qos input map cos enable
Router(config-subif)# plim qos input map cos
cos-value | cos-range queue low-latency | 0

Verifying Subinterface Configuration on a VLAN

To verify the configuration of a subinterface and its status on the VLAN, use the show vlans privileged EXEC
command.

Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Software Configuration Guide, Cisco IOS XE
Purpose
Enables packet classification based on 802.1q VLAN
COS bits.
By default, this command is enabled on the Gigabit
Ethernet SPA.
The no form of this command totally disables the
COS classification.
The command is used in the dot1q subinterface
configuration mode which can be either under the
main physical interface or the Gigabit EtherChannel
(GEC) link bundle.
Allows the user to specify which COS value or range
for high priority (low-latency) or low priority (0).
By default, without this command, COS value 6-7 is
classified as high priority. Only the default behavior
is supported when the hw-module subslot ethernet
vlan unlimited command is configured.
The no form of this command sets the classification
according to the default value (COS priority value
6-7).
This command is in the VLAN subinterface
configuration mode under either the main physical
interface or the GEC link bundle.
