802.3ad bonding to Cisco Switch

Thu Mar 09, 2017 3:43 pm

I found a previous post relating to this subject that did not answer my issue...viewtopic.php?t=110400

I am using a CCR1036-12G-4S (6.37.4) and bonding 2 SFP modules to a Cisco Nexus 3064 switch. The bonding does not seem to be working properly. I expect it is an issue with the Mikrotik configuration as I am seeing data coming from the switch on both ports, but data originating from the Mikrotik is only traveling on one interface. I have 2 devices on the other side of the switch that are both generating/receiving data (Each device is on a different network and segmented via VLANs). While I would not expect to see even traffic flow on the Ethernet Interfaces, I would expect traffic on both.

As you have bonded the two ports on the switch you may be experiencing and issue with STP and RSTP. have you tried connecting just 1 and seeing if traffic flows?
I have Spanning Tree Disabled on the VLANs. It is traffic originating from the Mikrotik that is going only on one interface. Traffic from the switch is being distributed on both interfaces. When I had it originally connected, I was not passing Layer 3 traffic and saw that I forgot to set the Hash Policy to layer 2 and 3 (was set to 2). I did get it working by unplugging one of the ports and then saw my goof and plugged the port back in again.

I see that you deleted your response, but I wanted to answer it anyways.

Do you not need to put Channel-group 1 mode active on interfaces for them to advertise.

Sorry I saw I miss-read your post that is why I deleted mine. When I re-read it I realized you had figured that out already and you have confirmed that.

That maybe the issue. I am going to move the traffic off of the bond and see if I can fix it and move the traffic back.

That was the issue. The Cisco Interfaces now look as follows...

interface Ethernet1/17
switchport mode trunk
switchport trunk allowed vlan 206,607
speed 1000
channel-group 1 mode active

interface Ethernet1/18
switchport mode trunk
switchport trunk allowed vlan 206,607
speed 1000
channel-group 1 mode active

The Mikrotik is now showing traffic.

I guess you should never do things when you are half asleep.
