I am configuring a pair of Cisco 3750e Switches for Etherchannel to use on a VM ESX server. I would appreciate your assistance to review my config to be sure that the interfaces do not flap or start a spanning tree loop. Please see below. Thank you in advance for your help.
I have all of the interface shut down intentionally at present.
System image file is "flash:c3750e-universalk9-mz.122-44.SE2/c3750e-universalk9-mz.122-44.SE2.bin"
interface Port-channel8
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,28
switchport mode trunk
shutdown
end
interface GigabitEthernet1/0/19
description SERVER1

end
interface GigabitEthernet2/0/15
