那篇cisco配置文章有如下描述
To configure Layer 3 EtherChannels, you create the port-channel logical interface and then put the Ethernet interfaces into the port-channel as described in the next two sections.
Creating Port-Channel Logical Interfaces
-------------------------------------------------------------
Note To move an IP address from a physical interface to an EtherChannel, you must delete the IP address from the physical interface before configuring it on the port-channel interface
在配置案例里是如下
This example shows how to create the logical port channel (5) and assign 172.10.20.10 as its IP address:
Switch# configure terminal Switch(config)# interface port-channel 5 Switch(config-if)# no switchport Switch(config-if)# ip address 172.10.20.10 255.255.255.0 Switch(config-if)# end 但我觉得它在配置channel ip前,该channel应该已经存在

In my view,U should config the int as a "port-channel"with the comm "int port-channel ×",then bundle the VI to the real phy int with the comm "channel-group x".作者: 马儿快跑 时间: 2003-2-21 11:04
与FEC无关。在L3交换机的端口上也设IP地址。作者: wxia 时间: 2003-2-26 14:52
可以不用设的呀,这句话“To configure Layer 3 EtherChannels, you create the port-channel logical interface and then put the Ethernet interfaces into the port-channel as described in the next two sections.”是说你要配好portchannel,然后要将ether接口配置到portchannel里,象接下来的2节中描述的。这是catalyst的native ios软件中需要这样作的,在cat os中命令不同作者: evenliu 时间: 2003-2-28 10:56
[q]做以太通道的一个问题
着个是我在xici提问的,大体解决的差不多了,现将整个解决过程share,还有一个遗留问题(在最后),希望版主解决

希望大家看东西一定要仔细,其实上面写的实在清楚!!
For Layer 3 EtherChannels, assign the Layer 3 address to the port-channel logical interface, not to the physical interfaces in the channel.
还有一些要注意:
The MAC address of a Layer 3 EtherChannel is the MAC address of the first interface in the port-channel.
using source addresses or IP addresses might result in better load balancing.
jifei-3550-level2(config)#interface range fa0/23 -24
jifei-3550-l(config-if-range)#no ip address
jifei-3550-l(config-if-range)#channel-group 10 mode desirable
Command rejected (Port-channel10): Either port is L2 and port-channel is L3, or vice-versa
