Sw1 and Sw2 Layer 3 Ether Channel use port-channe 21 only ?Assign YY.YY.100.1/24 to SW1 port-channel 21 ?Assign YY.YY.100.2/24 to SW2 port-channel 21 ? Ensure interface F0/23 and F0/24 are channel member for both switch ? Do NOT reply on PAgP of LACP to facilitate the connection (mode on) ? Verify Layer 2 and Layer 3 connectivity via channel link interface FastEthernet0/23 -24 no switchport channel-group 21 mode on interface Port-channel21 ip address Y.Y.100.1/2 Check command: show etherchannel,show ip int port-channel… 1.3 Port-channel between Sw1, Sw3 and Sw2, Sw4 ? Sw1, Sw3, Sw2 and Sw4 Layer 2 Etherchannel use port 10 only. ? F0/19 and F0/20?are members of switches. ? On Sw2 and Sw4 assign all interface in the Etherchannel as static-access port in VLAN_200 Uncondition enable PAgP to facilitate the connection. ? Verify Layer 2 connectivity via channel link.
