重新启动数据包跟踪器后的EtherChannel端口独立

Question

我有两个L3交换机(思科3560)，no switcport端口连接到L2交换机(Cisco2960)。它曾经正常工作，但是当我保存和重新启动Packet时--所有端口都进入了独立模式。这是端口的配置：

Vlan-40-Main (L3)：

interface Port-channel5
 no switchport
 ip address 192.168.100.7 255.255.255.0
!
interface FastEthernet0/1
 no switchport
 no ip address
 channel-group 5 mode active
 duplex auto
 speed auto
!
interface FastEthernet0/2
 no switchport
 no ip address
 channel-group 5 mode active
 duplex auto
 speed auto
!

Vlan-30-Main (L3)：

interface Port-channel6
 no switchport
 ip address 192.168.100.6 255.255.255.0
!
interface FastEthernet0/1
 no switchport
 no ip address
 channel-group 6 mode active
 duplex auto
 speed auto
!
interface FastEthernet0/2
 no switchport
 no ip address
 channel-group 6 mode active
 duplex auto
 speed auto
!

上层-Trunk2 2 (L2)：

interface Port-channel1
 switchport mode trunk

interface Port-channel2
 switchport mode trunk

Group  Port-channel  Protocol    Ports
------+-------------+-----------+----------------------------------------------

1      Po1(SD)           LACP   Fa0/1(I) Fa0/2(I) 
2      Po2(SD)           LACP   Fa0/3(I) Fa0/4(I) 
3      Po3(SU)           LACP   Fa0/5(P) Fa0/6(P)

您不能将第三层通道连接到第二层主干通道，因为第三层通道只能处理本机VLAN，除非为其创建子接口。请记住，交换机上的第三层接口基本上与路由器接口相同.

你需要这样的东西：

interface Port-channel5
 description Native VLAN
 no switchport
 encapsulation dot1Q <VLAN Number N> native
 ip address 192.168.100.7 255.255.255.0
!
interface Port-channel5.<VLAN Number X>
 description VLAN <VLAN Number X>
 encapsulation dot1Q <VLAN Number X>
 ip address <VLAN X IP address> <VLAN X Mask>
!
interface Port-channel5.<VLAN Number Y>
 description <VLAN Number Y>
 encapsulation dot1Q <VLAN Number Y>
 ip address <VLAN Y IP address> <VLAN Y Mask>
!
interface FastEthernet0/1
 no switchport
 no ip address
 channel-group 5 mode active
!
interface FastEthernet0/2
 no switchport
 no ip address
 channel-group 5 mode active
!
