Here’s an example of EtherChannel configuration.

SW1 SW2
Port fa0/21 to port fa0/21 SW2 Port fa0/21 to port fa0/21 SW1
Port fa0/22 to port fa0/22 SW2 Port fa0/22 to port fa0/22 SW1
Port fa0/23 to port fa0/23 SW2 Port fa0/23 to port fa0/23 SW1
Port fa0/24 to port fa0/24 SW2 Port fa0/24 to port fa0/24 SW1
Port fa0/1 to PC1 Port fa0/1 to PC3
Port fa0/2 to PC2 Port fa0/2 to PC4

PC1 : 10.10.10.1/24 – VLAN 10
PC2 : 10.10.20.1/24 – VLAN 20
