Cisco and Mikrotik bonding

RouterOS General
1

I have a Cisco 3560-X switch and a 1036. Trying to get some bonding working.

Cisco Config

interface Port-channel1
 switchport trunk allowed vlan 11,350,3200,3201
 switchport mode trunk
!
interface GigabitEthernet1/0/1
 description TO_CCR1036_PORT1
 switchport trunk allowed vlan 11,350,3200,3201
 switchport mode trunk
 channel-group 1 mode on
!
interface GigabitEthernet1/0/2
 description TO_CCR1036_PORT2
 switchport trunk allowed vlan 11,350,3200,3201
 switchport mode trunk
 channel-group 1 mode on

Mikrotik Config

/interface bonding
add link-monitoring=none mode=802.3ad name=bonding1 slaves=ether1,ether3,ether4




/interface bonding> print
Flags: X - disabled, R - running 
 0  R name="bonding1" mtu=1500 mac-address=6C:3B:6B:08:BA:C4 arp=enabled 
      arp-timeout=auto slaves=ether1,ether3,ether4 mode=802.3ad primary=none 
      link-monitoring=none arp-interval=100ms arp-ip-targets="" 
      mii-interval=100ms down-delay=0ms up-delay=0ms lacp-rate=30secs 
      transmit-hash-policy=layer-2 min-links=0

I have vlans underneath the bonding interface (see attachment).

Traffic does not load balance. All my traffic comes in one of the ethernet ports and goes out another.

How does “all your traffic” actually look like MAC-address-, IP-address-, and port-wise?

A single connection (same combination of source and destination MAC addresses, IP address, and ports) always uses the same link in LACP mode. By default, transmit-hash-policy is set to layer2, so only MAC addresses are taken into account when choosing a link for a given frame. You can change that to layer-2-and-3 if load distribution per IP address combination makes sense in your scenario, or layer-3-and-4 if you need to take the combination of ports into account.

If you test using just a few connections, you may still see one link to be preferred. This is normal, as the choice is done using a static hash (the same link will always be chosen for the same combination of mac addresses, IP addresses, and ports), and as the probability that the remainder of division of the hash by the number of links will be distributed evenly is very low.

Each device uses its own independent load distribution policy. So you have to choose an appropriate link selection policy at Cisco side as well.

After reviewing configs on a similiar setup I found my error I think.
port-channel load-balance dst-ip

I need that to add to my cisco. Your response helped jog my memory.
