3750 SFP bonding 1

[dayhawk]

I have 2 3700 Series switches, each with 4 1Gbps SFP ports. I want to know if there is a way to bond these ports together to make a single 4Gbps uplink between the switches. If this is possible, how would I accomplish this? Thanks in advance.

Yes... The technology is call etherchannel. You'll use the channel-group command to make port groups.

So will this work?

interface GigabitEthernet0/2
no ip address
channel-group 1 mode on
!
interface GigabitEthernet0/3
no ip address
channel-group 1 mode on
!
interface GigabitEthernet0/4
no ip address
channel-group 1 mode on

and i am assuming that the 'switchport mode trunk' command has to be entered for each interface? i didn't include that in the config in my previous post

Yes... Then you will configure the "interface po1" or port group 1. There you will put the "switchport mode trunk" and any other configuration commands.
