Configuration Example for Using the VLAN Group Feature to Apply QoS on Member Links
Consider a GEC bundle interface with two member links Gig3/0/0 and Gig4/0/0.
Step 1
Assume subinterfaces exist on the GEC bundle interface having the following configurations:
Step 2
Port-channel 1.1
Port-channel 1.2
Port-channel 1.3
Assume that the following configurations need to be performed on each member link

OL-2226-23
Both ingress and egress service-policy without any queuing actions can only be applied on member
links for M:N deployment, and are restricted for 1:N deployment.
Egress service-policy with queuing action can only be applied on:
Member interfaces for an M:N GEC deployment
–
–
Bundle interface for a 1:N GEC deployment.
Restriction for application of QoS on VLAN groups:
–
A VLAN group restricts the application of QoS to a maximum of 255 individual dot1Q (VLAN)
subinterfaces. 255 denotes the number of user classes that can be used in VLAN group parent
policy.
Matching a VLAN group user class on QinQ subinterfaces is not supported using VLAN group
–
policy. Each VLAN group user class at parent hierarchy can only match a set of dot1Q
subinterfaces.
VLAN group QoS policy at member link is used only when dot1Q subinterfaces are defined on
–
the GEC bundles and not when QinQ subinterfaces are defined on the GEC bundle.
Input Quality of Service (QoS) on member links is not supported for QinQ subinterfaces.
The classification criteria of match input-interface port-channel is not supported. Instead, packets
are classified by matching them with member-links.
