做813上的lacp实验时候，lacp总是起不来，我单独使用两台交换机做lacp同样起不来，每次都是active端的是down，而passive端是up的，请高手帮忙看下哪里出了问题，以下是我的配置：
SW2:
interface FastEthernet0/1
channel-protocol lacp
channel-group 1 mode active
switchport trunk native vlan 99
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface FastEthernet0/2
channel-protocol lacp
channel-group 1 mode active
switchport trunk native vlan 99
switchport trunk encapsulation dot1q
switchport mode trunk
interface Port-channel 1
switchport trunk native vlan 99
switchport trunk encapsulation dot1q
switchport mode trunk
SW2#sh etherchannel summary
Flags:  D - down        P - in port-channel
        I - stand-alone s - suspended
        H - Hot-standby (LACP only)
        R - Layer3      S - Layer2
        U - in use      f - failed to allocate aggregator
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port
