简述Ethernet Channel Technology 与PAgP （Port Aggregation Protocol ） 的区别

第1题：

• C、 Changes in configuration to the SAN port channel interface must also be made to all members of the channel group.
• D、 The port channel protocol uses the exchange fabric parameters command to communicate across peer ports in an ISL.
• E、 The port channel protocol ensures that a set of ports is eligible to be part of the same SAN port channel.
