I'm attempting to figure out how to get my 3560X to load balance a LACP port-channel that is going to a server. So about 90% of the traffic goes through one port.
Port-Channel 4: GigabitEthernet0/14: GigabitEthernet0/48:
868066479 packets input 235817603 packets input 632250162 packets input
891377158 packets output 828493193 packets output 62885071 packets output
EtherChannel Load-Balancing Configuration:
src-mac
Ports in the Port-channel:
Index Load Port EC state No of bits
------+------+------+------------------+-----------
0 00 Gi0/14 Active 0
0 00 Gi0/48 Active 0
ip cef load-sharing algorithm universal 6F1DD053
I'm not understanding why both ports have a "Load" value of 00. Any assistance on what I could do to more evenly load balance across the port channel would be appreciated.

Have you already tried configuring a more granular/balanced load balancing algorithm? The way it's setup now is the source MAC will always use the same port-channel member.
You could test using MAC + IP + Port # in the load balance algorithm to get more even load:
config t
port-channel load-balance src-dst-port

I recall(?) the 3560X might not support src-des-port, i.e.:
3560X(config)#port-channel load-balance ?
dst-ip Dst IP Addr
dst-mac Dst Mac Addr
src-dst-ip Src XOR Dst IP Addr
src-dst-mac Src XOR Dst Mac Addr
src-ip Src IP Addr
src-mac Src Mac Addr
If you only find the above, suggest trying src-dest-ip.
