Cisco Port Aggregation

i have a synology nas with 4 1GB ports and a Dell R710 server with 8 ports

 

I want to Configure Link Aggregation

 

so i configured

port 13-20  = 8 ports 

port channel group 1 on

port 21-24 =  4 

port channel group 2 on

 

nothing  on the switch can speak to those port channels

 

where have i gone wrong

 

 

Thanks

John

Hi 

Can you share me your switch configuration , 

Similarly have enabled NIC teaming on your Dell & NAS server ??

It's not server dependent, it is OS dependent, whatever OS or Hypervisor you installed in your server
You need to match that on the switch

for VMWare they support mode ON, so your config above works, but you need to change the hashing on the ports to "route based on IP Hash"

for Windows Hyper-V, it supports both ON and active(LACP), on your hypervisor you select either static for ON, and LACP for well, LACP


your config doesn't stop there, you need to configure your OS/Hypervisor the corresponding vSwitch.

All in all, you lack configuration on your server itself
 

Hi John,

 

          When you create NIC teaming on your Dell server (I assume you are not using Hypervisor) , what type of teaming you have chosen.

If you have chosen Smart Load balancing, you don't need to configure etherchannel on your switch. But try to avoid that.

If you have chosen 802.3ad Link Aggregation (LACP), the configuration on your switch should be " channel-group 1 mode active "

 

 

 

Cheers
