etherchannel between 2960s & QNAP

[chpmotry]

hi guys.

i have a Qnap device that i created a trunk port with two interfaces and 802.3ad protocol and MAC state. and i connected those two to the switch .i created an etherchannel in the switch with LACP protocol and active Mode. the trunk port in the switch is up . etherchannel output rate is 146mbps ,but its input rate is 18mbps. Qnap shows me that the speed of store data to the storages is about 18MBps.i will this speed reaches to up than 200MBps.

what  i do in switch

in below i put my configuration in the Qnap & 2960s-LPD Cisco switch

my configuration in QNAP

etherchannel loadbalance src-mac
interface Port-channel10
switchport trunk native vlan 4
switchport mode trunk

interface GigabitEthernet1/0/5

switchport trunk native vlan 4
switchport mode trunk

!
interface GigabitEthernet1/0/6

switchport trunk native vlan 4
switchport mode trunk

according to the output, there is no packet drops or error. so it seems like working fine. check if your storage can provide that much throughput with configured disks and IOPS.

Can you post below output ;

show interface GigabitEthernet1/0/5

show interface GigabitEthernet1/0/6

also prefer to see full config - show run

show sdm prefer 

You used LB algorithm - src-mac

what did you configure on QNAP side - it should match Layer 2 MAC (rather Layer2+3(MAC+IP)

Select a HASH policy for 802.3ad:
The default setting is “layer 2 (MAC)“. This is compatible with every switch but only offers load balancing by MAC address. We recommend using “Layer 2+3 (MAC+IP)” for greater performance but you will need to check that your switch supports it.

Note : 

1. Port Trunking cannot break the speed limit of a single Ethernet device, but it offers a sufficient amount of bandwidth for multiple users connecting at the same time. For example, if two 1Gb NICs are used for Port Trunking, the aggregated network bandwidth will be increased to 2Gb, but the network speed will remain 1Gb.
