LAG（Link Aggregation Group）只能配置在UNI端口上。

A .  Layer 3 routing between the Access and Aggregation layers facilities the ability to span VLANsacross multiple access switches， which is a requirement for many server virtualization andclustering technologies. B .  “East-west” server-to-server traffic can travel between aggregation modules by way of the core，but backup and replication traffic typically remains within an aggregation module. C .  Load balancing， firewall service， and other network service are commonly integrated by the useof service modules that are inserted in the aggregation switched. D .  Virtualization tools allow a cost effective approach for redundancy in the network design byusing two or four VDCs from the same physical switch.

A . Configuration changes made on the port-channel interface apply to all physical ports assigned to the portchannel interface. B . Configuration changes made on a physical port that is a member of a port-channel interface apply to the port-channel interface. C . Configuration changes are not permitted with Port Aggregation Protocol； instead， the standardized Link Aggregation Control Protocol should be used if configuration changes are required. D . The physical port must first be disassociated from the port-channel interface before any configuration changes can be made.
