Trunk trunk link, Ethernet channel
The purpose of the experiment is to logically divide a network into several small virtual Lans by dividing VLAN, and do Ethernet channels between switches to balance its load and improve its bandwidth.
C1 can interoperate with C3, others cannot, and C2 and C4 can not.
1. The SW1 is configured as follows: add VLAN10,20, add F1 SW1 2 to vlan10, and F1 SW1 3 to vlan20. F1Accord1 and f1Comp0 are used as trunk and Ethernet channels.
2.. The sw2 is configured as follows: add VLAN10,20, add F1 sw2 2 to vlan10, and F1 sw2 3 to vlan20. F1Accord1 and f1Comp0 are used as trunk and Ethernet channels.
3. Configure the ip of C1, c2, c3, c4
C1 can interoperate with C3, others cannot, and C2 and C4 can not.
