Layer 3 Etherchannel

[Yankee123]

Hi, can someone say if this etherchannel configuration between a 3560 and 3750 switch is correct, thanks.

3750

int range fa0/11 - 12
description ETHER CHANNEL TRUNK LINK TO S3750
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 2
switchport trunk allowed vlan 1-20
no switchport
channel-group 1 mode on
no shut
exit

int po1
description ETHER CHANNEL TRUNK LINK TO S3750 - 192.168.2.50
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 2
switchport trunk allowed vlan 1-20
ip address 192.168.2.49 255.255.255.252
no shut
exit

Yankee123,

Ether-channels are either layer 2 or Layer3.

You can not have switchport commands and "IP address" on the same interface as it shows on po1.

Thanks
