Hello,
I can not deal with Bonding between C3750 and MikroTik ver. 6.33.3 which I use as a hub for PPPoE clients. Has anyone done similar things at home and whether it is worth it or better to immediately invest in a 10Gbps card.
Below I am describing the config:
interface FastEthernet0 / 19
switchport trunk allowed vlan XX XX XX
switchport mode trunk
channel-group 3 mode active
channel-protocol lacp
!
interface FastEthernet0 / 20
switchport trunk allowed vlan XX XX XX
switchport mode trunk
channel-group 3 mode active
channel-protocol lacp
On MT I have:
name = "bonding" mtu = 1500 mac-address = 00: 0C: 42: 38: B5: 7D arp = enabled
slaves = ether6, ether5 mode = 802.3ad primary = none link-monitoring = mii
arp-interval = 100ms arp-ip-targets = 0.0.0.0 mii-interval = 100ms
down-delay = 0ms up-delay = 0ms lacp-rate = 30secs
transmit-hash-policy = layer-2-and-3 min-links = 0
If someone was making link aggregation on similar hardware, I would be grateful for any tips
because in the current configuration, only one card is moving. In case when I have MT
ballanced on the CISCO chanel-group 3 mode on the movement spreads evenly only on the Tx side
Re: MikroTik Bonding do C3750
I have a couple CCR1036 bonded to C3750 stacks.
This is working:
Router side
Switch side:
Hope, that helps.

EDIT: Now I just see what your real problem is.
That's a (problem/bug/unsupported feature) on the Cisco side. As you can see, the routers spread well, the switch doesn't :-(
This is working:

Re: MikroTik Bonding do C3750
Load balancing only happens in the outbound (Tx) direction.
Your hash policy on the MikroTik is layer 2 and layer 3.
What is it on the Cisco?
I have a 2960 with gigabit uplinks ($45 shipped to my door!) set like this:
It doesn't work so well with NAT coming from the WAN because the router is always the source IP or MAC so it tends to stay on one "side" of the etherchannel.
If yours supports src-dst-ip-port or something like that, you should probably try that. Mine doesn't.

Re: MikroTik Bonding do C3750
Hi,
Try channel-group mode on on switch and balance-rr on mikrotik.

Re: MikroTik Bonding do C3750
WItam, I need to do cisco etherchannel but I have tagged traffic. Tagged vlan-s from 100 - 400
switchport mode tunk
switchport trunk allow vlan 100-400
chanel group 3 mode on
On MikroTik ballance rr
Or
switchport mode tunk
switchport trunk allow vlan 100-400
chanel group 3 mode avtice
chabel-protocol lacp
On MikroTik 802.3ad
I can not set flow control on the cisco side in any configuration
