Configuration restrictions and guidelines
When you configure an aggregation group, follow these restrictions and guidelines:
You cannot assign a port to a Layer 2 aggregation group if any of the following features are configured on the port:
MAC authentication (see Security Configuration Guide).
Port security (see Security Configuration Guide).
802.1X (see Security Configuration Guide).
Association between AC and cross connection (see MPLS Configuration Guide).
AC-VSI association (see MPLS Configuration Guide).
You cannot assign a port to a Layer 3 aggregation group if any of the following features are configured on the port:
Association between AC and cross connection (see MPLS Configuration Guide).
AC-VSI association (see MPLS Configuration Guide).
If a port is used as a reflector port for port mirroring, do not assign it to an aggregation group. For more information about reflector ports, see Network Management and Monitoring Configuration Guide.
Removing an aggregate interface also removes its aggregation group and causes all member ports to leave the aggregation group.
You must configure the same aggregation mode on the two ends of an aggregate link.
This switch series supports a maximum of 128 aggregation groups. As a best practice to ensure the operation of the service loopback groups, configure no more than 126 aggregation groups.
