Cisco Switch Etherchannel to Synology NAS

This topic is to discuss the following lesson:

Rene, this looks like outstanding work. Thanks for your efforts. I am going to be doing this exact same configurations, but with 4 ports as soon as I can arrange a maintenance window for the synology.

Hi Bill,

You are welcome, glad you like it. Hopefully you got it working!


Hi Rene,

Do you know of any Cisco switch that supports IOS with 12 ports or less that I can get for this?


Hi Rene
I have the RS812+ and a SG200-26. Would it be possible that you post some screenshots of the SG200 settings using the web interface instead of the CISCO protocol? thank you

Hi Franklin,

The 2960 and 3560 switches both have 8 port versions, those are nice for small labs.



Great Job man… You have saved me lots of time. I have been trying to get Dynamic Link Aggregation configured with Synology for hours. I though I had to place the port-channel into trucking mode.

At any rate, Thank you for the outstanding work.

You are welcome Shawn and thank you for your kind words!

Nice Boss ! (y)

Is there a reason why you are using access mode for the etherchannel instead of trunk mode ? as I see there in the screenshot of the Nas there is a box to tick to enable dot1q.
Are these normally set as access ports ?

Hello Sean

The option of enabling 802.1Q is independent of the configuration of Etherchannel. You can enable or disable a trunk on the NAS end of the link whether you have configured EtherChannel or not. In any case, it seems that the NAS is capable of using trunk encapsulation. There is also a field to indicate which VLAN or VLANs will be included in the trunk. To be honest, I’m not sure what advantages the use of a trunk on the NAS will have, other than allowing the device to have multiple IP addresses, one within each VLAN, allowing multiple subnets to have access to it directly.

I hope this has been helpful!
