Etherchannel - Config Question

[hutcha4113]

First time configuring etherchannel.  I have followed the documentation, watched videos, etc.  The channel is up, but wanted to verify I did it right - and have not missed something.

Scenario:

Connecting a brand new 3650X into a 3750.  The 3750 is the "Core" and does the layer 3 routing, etc.  The 3650 is going to become a new Server Backbone - should participate on VLAN 10 only.  All servers in our data farm will connect into it (eventually).

Normally we just create one trunk port on each switch and call it done (we do not have a big data farm/and or IT team) but I wanted to start looking at Etherchannel, etc.

Config - Core:

interface GigabitEthernet2/0/12
 description ***Trunk to 203 - Server Backbone***
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 10
 switchport mode trunk
 switchport nonegotiate
 channel-group 1 mode on

interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 10
 switchport mode trunk
 switchport nonegotiate
 

Server Backbone:

interface GigabitEthernet1/0/1
 description ***Server Backbone - Switch 3 - Trunk***
 switchport trunk allowed vlan 10
 switchport mode trunk
 switchport nonegotiate
 channel-group 1 mode on

interface Port-channel1
 switchport trunk allowed vlan 10
 switchport mode trunk
 switchport nonegotiate
 (Does not have the encapsulation command, as not available in that IOS - assuming it is automatic?).

Basically I am looking to improve throughput and redundancy.  Is there anything else I should add and/or change about what was configured?

(NOTE:  I know these may or may not be the best switches to use - but they are what we can afford on our budget).

Well, of course, you want more than one link in your port-channel, both for additional aggregate bandwidth and additional redundancy.

You may want to review whether you're using the optimal hashing algorithm for your port-channel.

See above.

Not sure what you mean by Optimal Hashing Algorithm (let me know what I have to look for).  Thanks for the reply.

Therea are two ports on the core and 2 on the backbone switch.  I just cut an pasted an interface from each (they are both configured the same).
