你可以象MSM样配置，把GE3,GE4配置成port channel ，同时可以在其上配置 subinterfaces (ISL or 802.1q encapsulated)
interface GigabitEthernet3 channel-group 1 interface GigabitEthernet4 channel-group 1 !--- Both port gig 3 and gig 4 are part of the channel group 1.
interface Port-channel1.2 encapsulation dot1Q 2 ip address 2.2.2.2 255.255.255.0
interface Port-channel1.3 encapsulation dot1Q 3 ip address 1.1.1.2 255.255.255.0
交换机中配置：假设x4232-L3版插在slot3 set port channel 3/1-2 156 set trunk 3/1 nonegotiate dot1q 1-1005 set trunk 3/2 nonegotiate dot1q 1-1005 set port channel 3/1-2 mode on
最后有一点要注重的是假如你要在内部GE上配置数据流ACLs,如ip access-group 等：x4232-L3不支持在GE Channel上配置这种ACLs,也不支持在其GEC子接口上的ACLx;同时其不支持动态ACLs,不支持ACLs logging,ACLs hit counters等。 因此你要配置ACLs,只能这样配置： interface gig 3 ip address 192.168.100.1 255.255.255.0 ip access-group 101 in
或 interface gig 3.10 encapsulation dot1q 10 ip address 192.168.100.1 255.255.255.0 ip access-group 99 out
而不能： interface gig 3 channel-group 1 interface gig 4 channel-group 1 interface port-channel 1 ip address 192.168.100.1 255.255.255.0 ip access-group 101 in 或 interface gig 3 channel-group 1 interface gig 4 channel-group 1 interface port-channel 1.10 encapsulation dot1q 10 ip address 192.168.100.1 255.255.255.0 ip access-group 99 out
